此编辑根据注释改进并解释了答案。
var search = location.search.substring(1);
JSON.parse('{"' + decodeURI(search).replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g,'":"') + '"}')
例
解析abc=foo&def=%5Basf%5D&xyz=5
在五个步骤:
abc=foo","def=[asf]","xyz=5
abc":"foo","def":"[asf]","xyz":"5
{"abc":"foo","def":"[asf]","xyz":"5"}
这是合法的JSON。
一种改进的解决方案允许在搜索字符串中包含更多字符。它使用reviver函数进行URI解码:
var search = location.search.substring(1);
JSON.parse('{"' + search.replace(/&/g, '","').replace(/=/g,'":"') + '"}', function(key, value) { return key===""?value:decodeURIComponent(value) })
例
search = "abc=foo&def=%5Basf%5D&xyz=5&foo=b%3Dar";
给
Object {abc: "foo", def: "[asf]", xyz: "5", foo: "b=ar"}
单线:
JSON.parse('{"' + decodeURI("abc=foo&def=%5Basf%5D&xyz=5".replace(/&/g, "\",\"").replace(/=/g,"\":\"")) + '"}')
JSON.parse('{"' + decodeURI(location.search.substring(1).replace(/&/g, "\",\"").replace(/=/g, "\":\"")) + '"}')
从ES6开始,Javascript提供了几种结构来创建针对此问题的高性能解决方案。
这包括使用URLSearchParams和迭代器
let params = new URLSearchParams('abc=foo&def=%5Basf%5D&xyz=5');
params.get("abc"); // "foo"
如果您的用例需要您将其实际转换为对象,则可以实现以下功能:
function paramsToObject(entries) {
let result = {}
for(let entry of entries) { // each 'entry' is a [key, value] tupple
const [key, value] = entry;
result[key] = value;
}
return result;
}
const urlParams = new URLSearchParams('abc=foo&def=%5Basf%5D&xyz=5');
const entries = urlParams.entries(); //returns an iterator of decoded [key,value] tuples
const params = paramsToObject(entries); //{abc:"foo",def:"[asf]",xyz:"5"}
我们可以使用Object.fromEntries(这是目前在第4阶段),替换paramsToObject
用Object.fromEntries(entries)
。
要迭代的值对是列表名称-值对,其中键是名称,值是值。
由于会URLParams
返回一个可迭代的对象,因此使用传播运算符而不是调用.entries
也将根据其规范生成条目:
const urlParams = new URLSearchParams('abc=foo&def=%5Basf%5D&xyz=5');
const params = Object.fromEntries(urlParams); // {abc: "foo", def: "[asf]", xyz: "5"}
注意:根据URLSearchParams规范,所有值都是自动字符串
正如@siipe所指出的,包含多个相同键值的字符串将被强制转换为最后一个可用值:foo=first_value&foo=second_value
本质上将变为:{foo: "second_value"}
。
按照这个答案:https : //stackoverflow.com/a/1746566/1194694没有确定如何处理它的规范,并且每个框架的行为都可能不同。
一个常见的用例是将两个相同的值连接到一个数组中,使输出对象成为:
{foo: ["first_value", "second_value"]}
这可以通过以下代码实现:
const groupParamsByKey = (params) => [...params.entries()].reduce((acc, tuple) => {
// getting the key and value from each tuple
const [key, val] = tuple;
if(acc.hasOwnProperty(key)) {
// if the current key is already an array, we'll add the value to it
if(Array.isArray(acc[key])) {
acc[key] = [...acc[key], val]
} else {
// if it's not an array, but contains a value, we'll convert it into an array
// and add the current value to it
acc[key] = [acc[key], val];
}
} else {
// plain assignment if no special case is present
acc[key] = val;
}
return acc;
}, {});
const params = new URLSearchParams('abc=foo&def=%5Basf%5D&xyz=5&def=dude');
const output = groupParamsByKey(params) // {abc: "foo", def: ["[asf]", "dude"], xyz: 5}
search string
解析器-无论它与URL关联如何,它都是设计的目的
Object.fromEntries
对于重复的按键不起作用。如果我们尝试做类似的事情?foo=bar1&foo=bar2
,我们只会得到{ foo: 'bar2' }
。例如,Node.js请求对象将其解析为{ foo: ['bar1', 'bar2'] }
let temp={};Object.keys(params).map(key=>{temp[key]=urlParams.getAll(key)})
ES6一线。干净简单。
Object.fromEntries(new URLSearchParams(location.search));
对于您的特定情况,它将是:
console.log(
Object.fromEntries(new URLSearchParams('abc=foo&def=%5Basf%5D&xyz=5'))
);
"http://place.com?foo=bar&hello=%40world&showThing"
生产{ hello: "@world", http://place.com?foo: "bar", showThing: "" }
?someValue=false
变成{ someValue: "false" }
?foo=bar1&foo=bar2
,我们只会得到{ foo: 'bar2' }
。Node.js请求对象将其解析为{ foo: ['bar1', 'bar2'] }
location.search
拆分&
以获取名称/值对,然后拆分=
。这是一个例子:
var str = "abc=foo&def=%5Basf%5D&xy%5Bz=5"
var obj = str.split("&").reduce(function(prev, curr, i, arr) {
var p = curr.split("=");
prev[decodeURIComponent(p[0])] = decodeURIComponent(p[1]);
return prev;
}, {});
使用正则表达式的另一种方法:
var obj = {};
str.replace(/([^=&]+)=([^&]*)/g, function(m, key, value) {
obj[decodeURIComponent(key)] = decodeURIComponent(value);
});
改编自John Resig的“搜索并替换”。
到目前为止,我发现的建议解决方案并未涵盖更复杂的场景。
我需要像这样转换查询字符串
https://random.url.com?Target=Offer&Method=findAll&filters%5Bhas_goals_enabled%5D%5BTRUE%5D=1&filters%5Bstatus%5D=active&fields%5B%5D=id&fields%5B%5D=name&fields%5B%5D=default_goal_name
变成这样的对象:
{
"Target": "Offer",
"Method": "findAll",
"fields": [
"id",
"name",
"default_goal_name"
],
"filters": {
"has_goals_enabled": {
"TRUE": "1"
},
"status": "active"
}
}
要么:
https://random.url.com?Target=Report&Method=getStats&fields%5B%5D=Offer.name&fields%5B%5D=Advertiser.company&fields%5B%5D=Stat.clicks&fields%5B%5D=Stat.conversions&fields%5B%5D=Stat.cpa&fields%5B%5D=Stat.payout&fields%5B%5D=Stat.date&fields%5B%5D=Stat.offer_id&fields%5B%5D=Affiliate.company&groups%5B%5D=Stat.offer_id&groups%5B%5D=Stat.date&filters%5BStat.affiliate_id%5D%5Bconditional%5D=EQUAL_TO&filters%5BStat.affiliate_id%5D%5Bvalues%5D=1831&limit=9999
进入:
{
"Target": "Report",
"Method": "getStats",
"fields": [
"Offer.name",
"Advertiser.company",
"Stat.clicks",
"Stat.conversions",
"Stat.cpa",
"Stat.payout",
"Stat.date",
"Stat.offer_id",
"Affiliate.company"
],
"groups": [
"Stat.offer_id",
"Stat.date"
],
"limit": "9999",
"filters": {
"Stat.affiliate_id": {
"conditional": "EQUAL_TO",
"values": "1831"
}
}
}
码:
var getParamsAsObject = function (query) {
query = query.substring(query.indexOf('?') + 1);
var re = /([^&=]+)=?([^&]*)/g;
var decodeRE = /\+/g;
var decode = function (str) {
return decodeURIComponent(str.replace(decodeRE, " "));
};
var params = {}, e;
while (e = re.exec(query)) {
var k = decode(e[1]), v = decode(e[2]);
if (k.substring(k.length - 2) === '[]') {
k = k.substring(0, k.length - 2);
(params[k] || (params[k] = [])).push(v);
}
else params[k] = v;
}
var assign = function (obj, keyPath, value) {
var lastKeyIndex = keyPath.length - 1;
for (var i = 0; i < lastKeyIndex; ++i) {
var key = keyPath[i];
if (!(key in obj))
obj[key] = {}
obj = obj[key];
}
obj[keyPath[lastKeyIndex]] = value;
}
for (var prop in params) {
var structure = prop.split('[');
if (structure.length > 1) {
var levels = [];
structure.forEach(function (item, i) {
var key = item.replace(/[?[\]\\ ]/g, '');
levels.push(key);
});
assign(params, levels, params[prop]);
delete(params[prop]);
}
}
return params;
};
obj=encodeURIComponent(JSON.stringify({what:{ever:','},i:['like']}))
。
这是简单的版本,显然您将需要添加一些错误检查:
var obj = {};
var pairs = queryString.split('&');
for(i in pairs){
var split = pairs[i].split('=');
obj[decodeURIComponent(split[0])] = decodeURIComponent(split[1]);
}
JSON.parse('{"' + decodeURIComponent(query.replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g,'":"') + '"}'));
为我工作
name[]=test1&name[]=test2
它将导致name[]=test2
我发现$ .String.deparam是最完整的预制解决方案(可以执行嵌套对象等)。查看文档。
对于您的具体情况:
Object.fromEntries(new URLSearchParams('abc=foo&def=%5Basf%5D&xyz=5'));
对于更常见的情况,有人想将查询参数解析为一个对象:
Object.fromEntries(new URLSearchParams(location.search));
如果您无法使用Object.fromEntries,这也将起作用:
Array.from(new URLSearchParams(window.location.search)).reduce((o, i) => ({ ...o, [i[0]]: i[1] }), {});
[...new URLSearchParams(window.location.search)].reduce((o, i) => ({ ...o, [i[0]]: i[1] }), {});
"http://place.com?foo=bar&hello=%40world&showThing
产生{ hello: "@world", http://place.com?foo: "bar", showThing: "" }
。尝试添加str.split("?").pop()
基于URLSearchParams最新标准(https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams)的另一种解决方案
function getQueryParamsObject() {
const searchParams = new URLSearchParams(location.search.slice(1));
return searchParams
? _.fromPairs(Array.from(searchParams.entries()))
: {};
}
请注意,此解决方案正在利用
Array.from(https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Array/from)
和_.fromPairs(https://lodash.com/docs#fromPairs为了简单起见,)。
创建更兼容的解决方案应该很容易,因为您可以访问searchParams.entries()迭代器。
我遇到了同样的问题,在这里尝试了解决方案,但是它们都没有真正起作用,因为我在URL参数中有数组,如下所示:
?param[]=5¶m[]=8&othr_param=abc¶m[]=string
因此,我最终编写了自己的JS函数,该函数使URI中的参数脱离数组:
/**
* Creates an object from URL encoded data
*/
var createObjFromURI = function() {
var uri = decodeURI(location.search.substr(1));
var chunks = uri.split('&');
var params = Object();
for (var i=0; i < chunks.length ; i++) {
var chunk = chunks[i].split('=');
if(chunk[0].search("\\[\\]") !== -1) {
if( typeof params[chunk[0]] === 'undefined' ) {
params[chunk[0]] = [chunk[1]];
} else {
params[chunk[0]].push(chunk[1]);
}
} else {
params[chunk[0]] = chunk[1];
}
}
return params;
}
if(chunk[0].search("\\[\\]") !== -1) {
是chunk[0]=chunk[0].replace(/\[\]$/,'');
const
而不是var
因为某人可能这样做createObjFromURI = 'some text'
,然后他们会弄乱代码。如果使用,const
则运行某人createObjFromURI = 'some text'
将出错,无法将值赋给常量变量。
使用ES6,URL API和URLSearchParams API。
function objectifyQueryString(url) {
let _url = new URL(url);
let _params = new URLSearchParams(_url.search);
let query = Array.from(_params.keys()).reduce((sum, value)=>{
return Object.assign({[value]: _params.get(value)}, sum);
}, {});
return query;
}
使用URLSearchParams
JavaScript Web API 非常简单,
var paramsString = "q=forum&topic=api";
//returns an iterator object
var searchParams = new URLSearchParams(paramsString);
//Usage
for (let p of searchParams) {
console.log(p);
}
//Get the query strings
console.log(searchParams.toString());
//You can also pass in objects
var paramsObject = {q:"forum",topic:"api"}
//returns an iterator object
var searchParams = new URLSearchParams(paramsObject);
//Usage
for (let p of searchParams) {
console.log(p);
}
//Get the query strings
console.log(searchParams.toString());
注意:IE不支持
对于Node JS,您可以使用Node JS API querystring
:
const querystring = require('querystring');
querystring.parse('abc=foo&def=%5Basf%5D&xyz=5&foo=b%3Dar');
// returns the object
我没有知道任何本机解决方案。如果您偶然使用该框架,则Dojo具有内置的反序列化方法。
否则,您可以自己简单地实现它:
function unserialize(str) {
str = decodeURIComponent(str);
var chunks = str.split('&'),
obj = {};
for(var c=0; c < chunks.length; c++) {
var split = chunks[c].split('=', 2);
obj[split[0]] = split[1];
}
return obj;
}
编辑:添加了decodeURIComponent()
有一个名为YouAreI.js的轻量级库,该库已经过测试,可以轻松实现。
YouAreI = require('YouAreI')
uri = new YouAreI('http://user:pass@www.example.com:3000/a/b/c?d=dad&e=1&f=12.3#fragment');
uri.query_get() => { d: 'dad', e: '1', f: '12.3' }
使用URLSearchParam接口执行此操作的最简单方法之一。
以下是工作代码段:
let paramObj={},
querystring=window.location.search,
searchParams = new URLSearchParams(querystring);
//*** :loop to add key and values to the param object.
searchParams.forEach(function(value, key) {
paramObj[key] = value;
});
这似乎是最好的解决方案,因为它考虑了多个同名参数。
function paramsToJSON(str) {
var pairs = str.split('&');
var result = {};
pairs.forEach(function(pair) {
pair = pair.split('=');
var name = pair[0]
var value = pair[1]
if( name.length )
if (result[name] !== undefined) {
if (!result[name].push) {
result[name] = [result[name]];
}
result[name].push(value || '');
} else {
result[name] = value || '';
}
});
return( result );
}
<a href="index.html?x=1&x=2&x=3&y=blah">something</a>
paramsToJSON("x=1&x=2&x=3&y=blah");
console yields => {x: Array[3], y: "blah"} where x is an array as is proper JSON
我后来决定也将其转换为jQuery插件...
$.fn.serializeURLParams = function() {
var result = {};
if( !this.is("a") || this.attr("href").indexOf("?") == -1 )
return( result );
var pairs = this.attr("href").split("?")[1].split('&');
pairs.forEach(function(pair) {
pair = pair.split('=');
var name = decodeURI(pair[0])
var value = decodeURI(pair[1])
if( name.length )
if (result[name] !== undefined) {
if (!result[name].push) {
result[name] = [result[name]];
}
result[name].push(value || '');
} else {
result[name] = value || '';
}
});
return( result )
}
<a href="index.html?x=1&x=2&x=3&y=blah">something</a>
$("a").serializeURLParams();
console yields => {x: Array[3], y: "blah"} where x is an array as is proper JSON
现在,第一个将仅接受参数,但是jQuery插件将获取整个url并返回序列化的参数。
这是我使用的一个:
var params = {};
window.location.search.substring(1).split('&').forEach(function(pair) {
pair = pair.split('=');
if (pair[1] !== undefined) {
var key = decodeURIComponent(pair[0]),
val = decodeURIComponent(pair[1]),
val = val ? val.replace(/\++/g,' ').trim() : '';
if (key.length === 0) {
return;
}
if (params[key] === undefined) {
params[key] = val;
}
else {
if ("function" !== typeof params[key].push) {
params[key] = [params[key]];
}
params[key].push(val);
}
}
});
console.log(params);
基本用法,例如
?a=aa&b=bb
Object {a: "aa", b: "bb"}
重复的参数,例如。
?a=aa&b=bb&c=cc&c=potato
Object {a: "aa", b: "bb", c: ["cc","potato"]}
缺少按键,例如
?a=aa&b=bb&=cc
Object {a: "aa", b: "bb"}
缺少值,例如
?a=aa&b=bb&c
Object {a: "aa", b: "bb"}
上面的JSON / regex解决方案在这个古怪的网址上引发语法错误:
?a=aa&b=bb&c=&=dd&e
Object {a: "aa", b: "bb", c: ""}
这是我的快速而又肮脏的版本,基本上是将以&分隔的URL参数拆分为数组元素,然后在该数组上进行迭代,以将以=分隔的键/值对添加到对象中。我正在使用encodeURIComponent()将编码的字符转换为它们的正常字符串等效项(因此%20变为空格,%26变为'&',依此类推):
function deparam(paramStr) {
let paramArr = paramStr.split('&');
let paramObj = {};
paramArr.forEach(e=>{
let param = e.split('=');
paramObj[param[0]] = decodeURIComponent(param[1]);
});
return paramObj;
}
例:
deparam('abc=foo&def=%5Basf%5D&xyz=5')
退货
{
abc: "foo"
def:"[asf]"
xyz :"5"
}
唯一的问题是xyz是一个字符串而不是一个数字(由于使用了deleteURIComponent()),但除此之外,它并不是一个不好的起点。
//under ES6
const getUrlParamAsObject = (url = window.location.href) => {
let searchParams = url.split('?')[1];
const result = {};
//in case the queryString is empty
if (searchParams!==undefined) {
const paramParts = searchParams.split('&');
for(let part of paramParts) {
let paramValuePair = part.split('=');
//exclude the case when the param has no value
if(paramValuePair.length===2) {
result[paramValuePair[0]] = decodeURIComponent(paramValuePair[1]);
}
}
}
return result;
}

建立在Mike Causer的答案之上我制作了此函数,该函数考虑了具有相同键(foo=bar&foo=baz
)和逗号分隔参数(foo=bar,baz,bin
)的多个参数。它还使您可以搜索某个查询键。
function getQueryParams(queryKey) {
var queryString = window.location.search;
var query = {};
var pairs = (queryString[0] === '?' ? queryString.substr(1) : queryString).split('&');
for (var i = 0; i < pairs.length; i++) {
var pair = pairs[i].split('=');
var key = decodeURIComponent(pair[0]);
var value = decodeURIComponent(pair[1] || '');
// Se possui uma vírgula no valor, converter em um array
value = (value.indexOf(',') === -1 ? value : value.split(','));
// Se a key já existe, tratar ela como um array
if (query[key]) {
if (query[key].constructor === Array) {
// Array.concat() faz merge se o valor inserido for um array
query[key] = query[key].concat(value);
} else {
// Se não for um array, criar um array contendo o valor anterior e o novo valor
query[key] = [query[key], value];
}
} else {
query[key] = value;
}
}
if (typeof queryKey === 'undefined') {
return query;
} else {
return query[queryKey];
}
}
输入示例:
foo.html?foo=bar&foo=baz&foo=bez,boz,buz&bar=1,2,3
输出示例
{
foo: ["bar","baz","bez","boz","buz"],
bar: ["1","2","3"]
}
如果您使用的是URI.js,则可以使用:
https://medialize.github.io/URI.js/docs.html#static-parseQuery
var result = URI.parseQuery("?foo=bar&hello=world&hello=mars&bam=&yup");
result === {
foo: "bar",
hello: ["world", "mars"],
bam: "",
yup: null
};
首先需要确定什么是变量:
function getVar()
{
this.length = 0;
this.keys = [];
this.push = function(key, value)
{
if(key=="") key = this.length++;
this[key] = value;
this.keys.push(key);
return this[key];
}
}
比刚刚读:
function urlElement()
{
var thisPrototype = window.location;
for(var prototypeI in thisPrototype) this[prototypeI] = thisPrototype[prototypeI];
this.Variables = new getVar();
if(!this.search) return this;
var variables = this.search.replace(/\?/g,'').split('&');
for(var varI=0; varI<variables.length; varI++)
{
var nameval = variables[varI].split('=');
var name = nameval[0].replace(/\]/g,'').split('[');
var pVariable = this.Variables;
for(var nameI=0;nameI<name.length;nameI++)
{
if(name.length-1==nameI) pVariable.push(name[nameI],nameval[1]);
else var pVariable = (typeof pVariable[name[nameI]] != 'object')? pVariable.push(name[nameI],new getVar()) : pVariable[name[nameI]];
}
}
}
并使用像:
var mlocation = new urlElement();
mlocation = mlocation.Variables;
for(var key=0;key<mlocation.keys.length;key++)
{
console.log(key);
console.log(mlocation[mlocation.keys[key]];
}
我还需要处理+
URL的查询部分(encodeURIComponent不是),因此我将Wolfgang的代码修改为:
var search = location.search.substring(1);
search = search?JSON.parse('{"' + search.replace(/\+/g, ' ').replace(/&/g, '","').replace(/=/g,'":"') + '"}',
function(key, value) { return key===""?value:decodeURIComponent(value)}):{};
就我而言,我使用jQuery获取可用于URL的表单参数,然后使用此技巧从中构建对象,然后可以轻松地更新对象上的参数并重建查询URL,例如:
var objForm = JSON.parse('{"' + $myForm.serialize().replace(/\+/g, ' ').replace(/&/g, '","').replace(/=/g,'":"') + '"}',
function(key, value) { return key===""?value:decodeURIComponent(value)});
objForm.anyParam += stringToAddToTheParam;
var serializedForm = $.param(objForm);
我这样做:
const uri = new URL('https://example.org/?myvar1=longValue&myvar2=value')
const result = {}
for (let p of uri.searchParams) {
result[p[0]] = p[1]
}
如果您需要递归,则可以使用小型js-extension-ling库。
npm i js-extension-ling
const jsx = require("js-extension-ling");
console.log(jsx.queryStringToObject("a=1"));
console.log(jsx.queryStringToObject("a=1&a=3"));
console.log(jsx.queryStringToObject("a[]=1"));
console.log(jsx.queryStringToObject("a[]=1&a[]=pomme"));
console.log(jsx.queryStringToObject("a[0]=one&a[1]=five"));
console.log(jsx.queryStringToObject("http://blabla?foo=bar&number=1234"));
console.log(jsx.queryStringToObject("a[fruits][red][]=strawberry"));
console.log(jsx.queryStringToObject("a[fruits][red][]=strawberry&a[1]=five&a[fruits][red][]=cherry&a[fruits][yellow][]=lemon&a[fruits][yellow][688]=banana"));
这将输出如下内容:
{ a: '1' }
{ a: '3' }
{ a: { '0': '1' } }
{ a: { '0': '1', '1': 'pomme' } }
{ a: { '0': 'one', '1': 'five' } }
{ foo: 'bar', number: '1234' }
{
a: { fruits: { red: { '0': 'strawberry' } } }
}
{
a: {
'1': 'five',
fruits: {
red: { '0': 'strawberry', '1': 'cherry' },
yellow: { '0': 'lemon', '688': 'banana' }
}
}
}
注意:它基于locutus parse_str函数(https://locutus.io/php/strings/parse_str/)。
