在使用AJAX调用的Web应用程序中,我需要提交一个请求,但要在URL的末尾添加一个参数,例如:
原始网址:
结果网址:
http://server/myapp.php?id = 10 &enabled = true
寻找一种JavaScript函数,该函数解析URL并查看每个参数,然后添加新参数或更新值(如果已经存在)。

Answers:
您需要调整的基本实现如下所示:
function insertParam(key, value) {
key = encodeURIComponent(key);
value = encodeURIComponent(value);
// kvp looks like ['key1=value1', 'key2=value2', ...]
var kvp = document.location.search.substr(1).split('&');
let i=0;
for(; i<kvp.length; i++){
if (kvp[i].startsWith(key + '=')) {
let pair = kvp[i].split('=');
pair[1] = value;
kvp[i] = pair.join('=');
break;
}
}
if(i >= kvp.length){
kvp[kvp.length] = [key,value].join('=');
}
// can return this or...
let params = kvp.join('&');
// reload page with new params
document.location.search = params;
}
这大约是正则表达式或基于搜索的解决方案速度的两倍,但这完全取决于查询字符串的长度和任何匹配项的索引
我为完成测试而基准的慢速正则表达式方法(慢了大约150%)
function insertParam2(key,value)
{
key = encodeURIComponent(key); value = encodeURIComponent(value);
var s = document.location.search;
var kvp = key+"="+value;
var r = new RegExp("(&|\\?)"+key+"=[^\&]*");
s = s.replace(r,"$1"+kvp);
if(!RegExp.$1) {s += (s.length>0 ? '&' : '?') + kvp;};
//again, do what you will here
document.location.search = s;
}
encodeURIComponent
而不是encodeURI
吗?否则=
,&
您的名称或值之类的任何字符(如)都会损坏URI。
您可以使用以下之一:
例:
var url = new URL("http://foo.bar/?x=1&y=2");
// If your expected result is "http://foo.bar/?x=1&y=2&x=42"
url.searchParams.append('x', 42);
// If your expected result is "http://foo.bar/?x=42&y=2"
url.searchParams.set('x', 42);
XML
到http://foo.bar/?x=1&y=2
,使最终结果为http://foo.bar/?x=1&y=2&XML
。这可能吗?我想url.searchParams.set('XML');
,url.searchParams.set('XML', null);
和url.searchParams.set('XML', undefined);
-但没有工作过的Chrome 63。
谢谢大家的贡献。我使用了annakata代码,并进行了修改,以包括网址中根本没有查询字符串的情况。希望这会有所帮助。
function insertParam(key, value) {
key = escape(key); value = escape(value);
var kvp = document.location.search.substr(1).split('&');
if (kvp == '') {
document.location.search = '?' + key + '=' + value;
}
else {
var i = kvp.length; var x; while (i--) {
x = kvp[i].split('=');
if (x[0] == key) {
x[1] = value;
kvp[i] = x.join('=');
break;
}
}
if (i < 0) { kvp[kvp.length] = [key, value].join('='); }
//this will reload the page, it's likely better to store this until finished
document.location.search = kvp.join('&');
}
}
escape(key)
和escape(value)
到encodeURIComponent
功能。
if (kvp.length==1 && kvp[0]="")
吗?
if (document.location.search)
这是非常简单的解决方案。它不控制参数的存在,并且不更改现有值。它将参数添加到末尾,因此您可以在后端代码中获取最新值。
function addParameterToURL(param){
_url = location.href;
_url += (_url.split('?')[1] ? '&':'?') + param;
return _url;
}
url = (url.indexOf("?") != -1 ? url.split("?")[0]+"?"+part+"&"+url.split("?")[1] : (url.indexOf("#") != -1 ? url.split("#")[0]+"?"+part+"#"+ url.split("#")[1] : url+'?'+part));
function appendQs(url, key, value) { return url + (url.indexOf('?') >= 0 ? "&" : '?') + encodeURIComponent(key) + "=" + encodeURIComponent(value); };

。
这是一个大大简化的版本,在易读性和较少的代码行数(而不是微优化的性能)之间进行了权衡(实际上,我们谈论的是几毫秒的差异,由于这种性质(在当前文档的位置上进行操作) ),则很可能会在页面上运行一次)。
/**
* Add a URL parameter (or changing it if it already exists)
* @param {search} string this is typically document.location.search
* @param {key} string the key to set
* @param {val} string value
*/
var addUrlParam = function(search, key, val){
var newParam = key + '=' + val,
params = '?' + newParam;
// If the "search" string exists, then build params from it
if (search) {
// Try to replace an existance instance
params = search.replace(new RegExp('([?&])' + key + '[^&]*'), '$1' + newParam);
// If nothing was replaced, then add the new param to the end
if (params === search) {
params += '&' + newParam;
}
}
return params;
};
然后,您将这样使用:
document.location.pathname + addUrlParam(document.location.search, 'foo', 'bar');
[\?&]
与([\?&])
在正则表达式(我只是编辑它自己,但我不知道如果社会政策允许的答案修复bug)。
/**
* Add a URL parameter
* @param {string} url
* @param {string} param the key to set
* @param {string} value
*/
var addParam = function(url, param, value) {
param = encodeURIComponent(param);
var a = document.createElement('a');
param += (value ? "=" + encodeURIComponent(value) : "");
a.href = url;
a.search += (a.search ? "&" : "") + param;
return a.href;
}
/**
* Add a URL parameter (or modify if already exists)
* @param {string} url
* @param {string} param the key to set
* @param {string} value
*/
var addOrReplaceParam = function(url, param, value) {
param = encodeURIComponent(param);
var r = "([&?]|&)" + param + "\\b(?:=(?:[^&#]*))*";
var a = document.createElement('a');
var regex = new RegExp(r);
var str = param + (value ? "=" + encodeURIComponent(value) : "");
a.href = url;
var q = a.search.replace(regex, "$1"+str);
if (q === a.search) {
a.search += (a.search ? "&" : "") + str;
} else {
a.search = q;
}
return a.href;
}
url = "http://www.example.com#hashme";
newurl = addParam(url, "ciao", "1");
alert(newurl);
并且请注意,在将参数附加到查询字符串之前,应先对其进行编码。
http://abc.def/?a&b&b
)。
我有一个“类”来做到这一点,这里是:
function QS(){
this.qs = {};
var s = location.search.replace( /^\?|#.*$/g, '' );
if( s ) {
var qsParts = s.split('&');
var i, nv;
for (i = 0; i < qsParts.length; i++) {
nv = qsParts[i].split('=');
this.qs[nv[0]] = nv[1];
}
}
}
QS.prototype.add = function( name, value ) {
if( arguments.length == 1 && arguments[0].constructor == Object ) {
this.addMany( arguments[0] );
return;
}
this.qs[name] = value;
}
QS.prototype.addMany = function( newValues ) {
for( nv in newValues ) {
this.qs[nv] = newValues[nv];
}
}
QS.prototype.remove = function( name ) {
if( arguments.length == 1 && arguments[0].constructor == Array ) {
this.removeMany( arguments[0] );
return;
}
delete this.qs[name];
}
QS.prototype.removeMany = function( deleteNames ) {
var i;
for( i = 0; i < deleteNames.length; i++ ) {
delete this.qs[deleteNames[i]];
}
}
QS.prototype.getQueryString = function() {
var nv, q = [];
for( nv in this.qs ) {
q[q.length] = nv+'='+this.qs[nv];
}
return q.join( '&' );
}
QS.prototype.toString = QS.prototype.getQueryString;
//examples
//instantiation
var qs = new QS;
alert( qs );
//add a sinle name/value
qs.add( 'new', 'true' );
alert( qs );
//add multiple key/values
qs.add( { x: 'X', y: 'Y' } );
alert( qs );
//remove single key
qs.remove( 'new' )
alert( qs );
//remove multiple keys
qs.remove( ['x', 'bogus'] )
alert( qs );
我已经重写了toString方法,因此无需调用QS :: getQueryString,您可以使用QS :: toString,或者像我在示例中所做的那样,仅依赖于被强制转换为字符串的对象。
const urlParams = new URLSearchParams(window.location.search);
urlParams.set('order', 'date');
window.location.search = urlParams;
.set第一个参数是关键,第二个是值。
如果您有一个要用参数修饰的带有url的字符串,则可以尝试以下操作:
urlstring += ( urlstring.match( /[\?]/g ) ? '&' : '?' ) + 'param=value';
这意味着什么?将是参数的前缀,但是如果已经有?在中urlstring
,将&用作前缀。
encodeURI( paramvariable )
如果您没有对参数进行硬编码,我也建议您这样做,但是它位于paramvariable
;中;或者其中有有趣的人物。
有关功能的用法,请参见javascript URL编码encodeURI
。
这是添加查询参数的简单方法:
const query = new URLSearchParams(window.location.search);
query.append("enabled", "true");
请注意支持规格。
查看https://github.com/derek-watson/jsUri
URI和javascript中的查询字符串操作。
该项目包含了Steven Levithan出色的parseUri正则表达式库。您可以安全地解析各种形状和大小的URL,但是这些URL无效或令人生厌。
以下功能将帮助您向URL添加,更新和删除参数。

这是我自己的尝试,但是我将使用annakata的答案,因为它看起来更干净:
function AddUrlParameter(sourceUrl, parameterName, parameterValue, replaceDuplicates)
{
if ((sourceUrl == null) || (sourceUrl.length == 0)) sourceUrl = document.location.href;
var urlParts = sourceUrl.split("?");
var newQueryString = "";
if (urlParts.length > 1)
{
var parameters = urlParts[1].split("&");
for (var i=0; (i < parameters.length); i++)
{
var parameterParts = parameters[i].split("=");
if (!(replaceDuplicates && parameterParts[0] == parameterName))
{
if (newQueryString == "")
newQueryString = "?";
else
newQueryString += "&";
newQueryString += parameterParts[0] + "=" + parameterParts[1];
}
}
}
if (newQueryString == "")
newQueryString = "?";
else
newQueryString += "&";
newQueryString += parameterName + "=" + parameterValue;
return urlParts[0] + newQueryString;
}
另外,我在stackoverflow的另一篇文章中找到了这个jQuery插件,如果您需要更大的灵活性,可以使用它:http : //plugins.jquery.com/project/query-object
我认为代码会(尚未测试):
return $.query.parse(sourceUrl).set(parameterName, parameterValue).toString();
添加到@Vianney的答案https://stackoverflow.com/a/44160941/6609678
我们可以按如下所示在节点中导入内置URL模块
const { URL } = require('url');
例:
Terminal $ node
> const { URL } = require('url');
undefined
> let url = new URL('', 'http://localhost:1989/v3/orders');
undefined
> url.href
'http://localhost:1989/v3/orders'
> let fetchAll=true, timePeriod = 30, b2b=false;
undefined
> url.href
'http://localhost:1989/v3/orders'
> url.searchParams.append('fetchAll', fetchAll);
undefined
> url.searchParams.append('timePeriod', timePeriod);
undefined
> url.searchParams.append('b2b', b2b);
undefined
> url.href
'http://localhost:1989/v3/orders?fetchAll=true&timePeriod=30&b2b=false'
> url.toString()
'http://localhost:1989/v3/orders?fetchAll=true&timePeriod=30&b2b=false'
有用的链接:
https://developer.mozilla.org/zh-CN/docs/Web/API/URL https://developer.mozilla.org/en/docs/Web/API/URLSearchParams
试试这个。
// uses the URL class
function setParam(key, value) {
let url = new URL(window.document.location);
let params = new URLSearchParams(url.search.slice(1));
if (params.has(key)) {
params.set(key, value);
}else {
params.append(key, value);
}
}
url.searchParams
是该URL
对象的预初始化参数列表。
我喜欢Mehmet FatihYıldız的回答,即使他没有回答整个问题。
在与他的答案相同的行中,我使用以下代码:
“它不会控制参数的存在,并且不会更改现有值。它将参数添加到末尾”
/** add a parameter at the end of the URL. Manage '?'/'&', but not the existing parameters.
* does escape the value (but not the key)
*/
function addParameterToURL(_url,_key,_value){
var param = _key+'='+escape(_value);
var sep = '&';
if (_url.indexOf('?') < 0) {
sep = '?';
} else {
var lastChar=_url.slice(-1);
if (lastChar == '&') sep='';
if (lastChar == '?') sep='';
}
_url += sep + param;
return _url;
}
和测试人员:
/*
function addParameterToURL_TESTER_sub(_url,key,value){
//log(_url);
log(addParameterToURL(_url,key,value));
}
function addParameterToURL_TESTER(){
log('-------------------');
var _url ='www.google.com';
addParameterToURL_TESTER_sub(_url,'key','value');
addParameterToURL_TESTER_sub(_url,'key','Text Value');
_url ='www.google.com?';
addParameterToURL_TESTER_sub(_url,'key','value');
_url ='www.google.com?A=B';
addParameterToURL_TESTER_sub(_url,'key','value');
_url ='www.google.com?A=B&';
addParameterToURL_TESTER_sub(_url,'key','value');
_url ='www.google.com?A=1&B=2';
addParameterToURL_TESTER_sub(_url,'key','value');
}//*/
这是在服务器端(例如Node.js)上进行一些基本url参数添加或更新时使用的方法。
CoffeScript:
###
@method addUrlParam Adds parameter to a given url. If the parameter already exists in the url is being replaced.
@param {string} url
@param {string} key Parameter's key
@param {string} value Parameter's value
@returns {string} new url containing the parameter
###
addUrlParam = (url, key, value) ->
newParam = key+"="+value
result = url.replace(new RegExp('(&|\\?)' + key + '=[^\&|#]*'), '$1' + newParam)
if result is url
result = if url.indexOf('?') != -1 then url.split('?')[0] + '?' + newParam + '&' + url.split('?')[1]
else if url.indexOf('#') != -1 then url.split('#')[0] + '?' + newParam + '#' + url.split('#')[1]
else url + '?' + newParam
return result
JavaScript:
function addUrlParam(url, key, value) {
var newParam = key+"="+value;
var result = url.replace(new RegExp("(&|\\?)"+key+"=[^\&|#]*"), '$1' + newParam);
if (result === url) {
result = (url.indexOf("?") != -1 ? url.split("?")[0]+"?"+newParam+"&"+url.split("?")[1]
: (url.indexOf("#") != -1 ? url.split("#")[0]+"?"+newParam+"#"+ url.split("#")[1]
: url+'?'+newParam));
}
return result;
}
var url = "http://www.example.com?foo=bar&ciao=3&doom=5#hashme";
result1.innerHTML = addUrlParam(url, "ciao", "1");
<p id="result1"></p>
最简单的解决方案,可以在您已经有标签的情况下工作,并自动将其删除,这样就不会继续添加相同的标签,请尽情享受
function changeURL(tag)
{
if(window.location.href.indexOf("?") > -1) {
if(window.location.href.indexOf("&"+tag) > -1){
var url = window.location.href.replace("&"+tag,"")+"&"+tag;
}
else
{
var url = window.location.href+"&"+tag;
}
}else{
if(window.location.href.indexOf("?"+tag) > -1){
var url = window.location.href.replace("?"+tag,"")+"?"+tag;
}
else
{
var url = window.location.href+"?"+tag;
}
}
window.location = url;
}
然后
changeURL("i=updated");
Vianney Bajart的答案是正确的;但是,仅当您具有带有端口,主机,路径和查询的完整URL 时,URL才起作用:
new URL('http://server/myapp.php?id=10&enabled=true')
仅当您传递查询字符串时,URLSearchParams才有效:
new URLSearchParams('?id=10&enabled=true')
如果您有不完整或相对的URL,并且不关心基本URL,则可以按以下?
方式拆分以获取查询字符串,然后像下面这样加入:
function setUrlParams(url, key, value) {
url = url.split('?');
usp = new URLSearchParams(url[1]);
usp.set(key, value);
url[1] = usp.toString();
return url.join('?');
}
let url = 'myapp.php?id=10';
url = setUrlParams(url, 'enabled', true); // url = 'myapp.php?id=10&enabled=true'
url = setUrlParams(url, 'id', 11); // url = 'myapp.php?id=11&enabled=true'
与Internet Explorer不兼容。
var u = new URL(window.location), usp = u.searchParams;
,则不必使用任何花哨的字符串拆分。
setUrlParams('https://example.com?foo=thing???&bar=baz', 'baz', 'qux') => "https://example.com?foo=thing&baz=qux???&bar=baz"
如果您在链接或其他地方弄乱了网址,则可能还必须考虑哈希值。这是一个相当简单易懂的解决方案。可能不是最快的, 因为它使用了正则表达式...但是在99.999%的情况下,差异实际上并不重要!
function addQueryParam( url, key, val ){
var parts = url.match(/([^?#]+)(\?[^#]*)?(\#.*)?/);
var url = parts[1];
var qs = parts[2] || '';
var hash = parts[3] || '';
if ( !qs ) {
return url + '?' + key + '=' + encodeURIComponent( val ) + hash;
} else {
var qs_parts = qs.substr(1).split("&");
var i;
for (i=0;i<qs_parts.length;i++) {
var qs_pair = qs_parts[i].split("=");
if ( qs_pair[0] == key ){
qs_parts[ i ] = key + '=' + encodeURIComponent( val );
break;
}
}
if ( i == qs_parts.length ){
qs_parts.push( key + '=' + encodeURIComponent( val ) );
}
return url + '?' + qs_parts.join('&') + hash;
}
}
好的,在这里我比较了两个函数,一个是我自己(regExp)制作的,另一个是(annakata)制作的。
分割数组:
function insertParam(key, value)
{
key = escape(key); value = escape(value);
var kvp = document.location.search.substr(1).split('&');
var i=kvp.length; var x; while(i--)
{
x = kvp[i].split('=');
if (x[0]==key)
{
x[1] = value;
kvp[i] = x.join('=');
break;
}
}
if(i<0) {kvp[kvp.length] = [key,value].join('=');}
//this will reload the page, it's likely better to store this until finished
return "&"+kvp.join('&');
}
正则表达式方法:
function addParameter(param, value)
{
var regexp = new RegExp("(\\?|\\&)" + param + "\\=([^\\&]*)(\\&|$)");
if (regexp.test(document.location.search))
return (document.location.search.toString().replace(regexp, function(a, b, c, d)
{
return (b + param + "=" + value + d);
}));
else
return document.location.search+ param + "=" + value;
}
测试案例:
time1=(new Date).getTime();
for (var i=0;i<10000;i++)
{
addParameter("test","test");
}
time2=(new Date).getTime();
for (var i=0;i<10000;i++)
{
insertParam("test","test");
}
time3=(new Date).getTime();
console.log((time2-time1)+" "+(time3-time2));
似乎即使使用最简单的解决方案(当regexp仅使用test而不输入.replace函数时),它仍然比拆分要慢...好。正则表达式有点慢,但是...呃...
这是我的工作。使用我的editParams()函数,您可以添加,删除或更改任何参数,然后使用内置的replaceState()函数更新URL:
window.history.replaceState('object or string', 'Title', 'page.html' + editParams('enable', 'true'));
// background functions below:
// add/change/remove URL parameter
// use a value of false to remove parameter
// returns a url-style string
function editParams (key, value) {
key = encodeURI(key);
var params = getSearchParameters();
if (Object.keys(params).length === 0) {
if (value !== false)
return '?' + key + '=' + encodeURI(value);
else
return '';
}
if (value !== false)
params[key] = encodeURI(value);
else
delete params[key];
if (Object.keys(params).length === 0)
return '';
return '?' + $.map(params, function (value, key) {
return key + '=' + value;
}).join('&');
}
// Get object/associative array of URL parameters
function getSearchParameters () {
var prmstr = window.location.search.substr(1);
return prmstr !== null && prmstr !== "" ? transformToAssocArray(prmstr) : {};
}
// convert parameters from url-style string to associative array
function transformToAssocArray (prmstr) {
var params = {},
prmarr = prmstr.split("&");
for (var i = 0; i < prmarr.length; i++) {
var tmparr = prmarr[i].split("=");
params[tmparr[0]] = tmparr[1];
}
return params;
}
最好的情况是,上述答案都不能解决查询字符串包含参数的情况,这些参数本身就是数组,因此会出现多次,例如:
http://example.com?sizes[]=a&sizes[]=b
以下功能是我编写的要更新的功能document.location.search
。它使用键/值对数组作为参数,并将返回后者的修订版,您可以根据需要进行操作。我正在这样使用它:
var newParams = [
['test','123'],
['best','456'],
['sizes[]','XXL']
];
var newUrl = document.location.pathname + insertParams(newParams);
history.replaceState('', '', newUrl);
如果当前网址是:
http://example.com/index.php?test=replaceme&sizes[]=XL
这会让你
http://example.com/index.php?test=123&sizes[]=XL&sizes[]=XXL&best=456
功能
function insertParams(params) {
var result;
var ii = params.length;
var queryString = document.location.search.substr(1);
var kvps = queryString ? queryString.split('&') : [];
var kvp;
var skipParams = [];
var i = kvps.length;
while (i--) {
kvp = kvps[i].split('=');
if (kvp[0].slice(-2) != '[]') {
var ii = params.length;
while (ii--) {

试试
正则表达式,太慢了,因此:
var SetParamUrl = function(_k, _v) {// replace and add new parameters
let arrParams = window.location.search !== '' ? decodeURIComponent(window.location.search.substr(1)).split('&').map(_v => _v.split('=')) : Array();
let index = arrParams.findIndex((_v) => _v[0] === _k);
index = index !== -1 ? index : arrParams.length;
_v === null ? arrParams = arrParams.filter((_v, _i) => _i != index) : arrParams[index] = [_k, _v];
let _search = encodeURIComponent(arrParams.map(_v => _v.join('=')).join('&'));
let newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + (arrParams.length > 0 ? '?' + _search : '');
// window.location = newurl; //reload
if (history.pushState) { // without reload
window.history.pushState({path:newurl}, null, newurl);
}
};
var GetParamUrl = function(_k) {// get parameter by key
let sPageURL = decodeURIComponent(window.location.search.substr(1)),
sURLVariables = sPageURL.split('&').map(_v => _v.split('='));
let _result = sURLVariables.find(_v => _v[0] === _k);
return _result[1];
};
例:
// https://some.com/some_path
GetParamUrl('cat');//undefined
SetParamUrl('cat', "strData");// https://some.com/some_path?cat=strData
GetParamUrl('cat');//strData
SetParamUrl('sotr', "strDataSort");// https://some.com/some_path?cat=strData&sotr=strDataSort
GetParamUrl('sotr');//strDataSort
SetParamUrl('cat', "strDataTwo");// https://some.com/some_path?cat=strDataTwo&sotr=strDataSort
GetParamUrl('cat');//strDataTwo
//remove param
SetParamUrl('cat', null);// https://some.com/some_path?sotr=strDataSort
通过JS的新成就,可以在这里向URL添加查询参数:
var protocol = window.location.protocol,
host = '//' + window.location.host,
path = window.location.pathname,
query = window.location.search;
var newUrl = protocol + host + path + query + (query ? '&' : '?') + 'param=1';
window.history.pushState({path:newUrl}, '' , newUrl);
另请参阅这种可能性Moziila URLSearchParams.append()
重置所有查询字符串
var params = { params1:"val1", params2:"val2" };
let str = jQuery.param(params);
let uri = window.location.href.toString();
if (uri.indexOf("?") > 0)
uri = uri.substring(0, uri.indexOf("?"));
console.log(uri+"?"+str);
//window.location.href = uri+"?"+str;
