建立在其他答案上！
该代码的调试版本，以及清理和jsbeautifier.org/。
(function() {
var ThisAction = 'https://your.urlgoes.here/build?delay=0sec';
/* A little JSON never hurt anyone */
var ThisPost = {
name: 'ENVIRONMENT',
value: 'production',
name: 'DEPLOYTYPE',
value: 'Incremental',
name: 'BRANCH',
value: 'master',
statusCode: '303',
redirectTo: '.',
json: '{"parameter": [{"name": "ENVIRONMENT", "value": "production"}, {"name": "DEPLOYTYPE", "value": "Incremental"}, {"name": "BRANCH", "value": "master"}], "statusCode": "303", "redirectTo": "."}',
Submit: 'Build'
};
/* Help us locate this function */
console.trace();
/* See what we are looking at */
console.log(document);
var form = document.getElementsByTagName('form')[0];
form.style.visibility = 'hidden';
form.method = 'post';
form.action = ThisAction;
for (var key in ThisPost) {
if (ThisPost.hasOwnProperty(key)) {
input = document.createElement('input');
input.name = key;
input.value = ThisPost[key];
form.appendChild(input);
}
}
/* form.submit(); */
})();
显然，如果没有相应的html，则标签名称为“ form”的元素很可能不存在……如果这样的话，情况会更糟。以上很好地说明了这一点。请注意，在Chrome javascript中：URI /书签在新标签中不起作用，您必须先浏览一次。这将填充文档对象，甚至只是javascript：alert（'t'）; 什么也没做。
我建议以下。
(function() {
var ThisAction = 'https://your.urlgoes.here/build?optional=uri_get';
/* A little JSON never hurt anyone */
var ThisPost = {
multiple: 'value',
key: 'pairs',
or: 'JSON like so...',
note: 'the double quotes and last item with NO trailing comma.',
json: '{parameter: [{name: "stuff"}]}'
};
var form = document.createElement('form');
form.style.visibility = 'hidden';
form.method = 'post';
form.action = ThisAction;
for (var key in ThisPost) {
if (ThisPost.hasOwnProperty(key)) {
var input = document.createElement('input');
input.name = key;
input.value = ThisPost[key];
form.appendChild(input);
}
}
document.body.appendChild(form);
form.submit();
})();
删除调试设置，清理示例输入，以更好地了解期望的内容。通过http://jscompress.com/或其他方式运行并获得一行。
!function(){var e="https://your.urlgoes.here/build?optional=uri_get",t={multiple:"value",key:"pairs",or:"JSON like so...",note:"the double quotes and last item with NO trailing comma.",json:'{parameter: [{name: "stuff"}]}'},i=document.createElement("form");i.style.visibility="hidden",i.method="post",i.action=e;for(var o in t)if(t.hasOwnProperty(o)){var a=document.createElement("input");a.name=o,a.value=t[o],i.appendChild(a)}document.body.appendChild(i),i.submit()}();
编辑：提供一个有效的示例。
在美国明尼苏达州明尼阿波利斯市，使用它可以访问免费WiFi ESSID“ USIW免费WiFi”。使用https://login.usiwireless.com/mplsfree/logon.php?originalurl=www.google.com/注册帐户后，出于滥用原因，他们希望使用信用卡。
使用它登录到网络，并进行明显的替换。
javascript:!function(){var e="https://login.usiwireless.com/mplsfree/logon.pl",o={usernameLogin:"USER",passwordLogin:"PASSWORD",originalurl:"www.google.com/"},n=document.createElement("form");n.style.visibility="hidden",n.method="post",n.action=e;for(var i in o)if(o.hasOwnProperty(i)){var t=document.createElement("input");t.name=i,t.value=o[i],n.appendChild(t)}document.body.appendChild(n),n.submit()}();
