Try this. It's pure javascript, no jQuery involved. In fact jQuery is too heavy for such a job, really.
尝试这个。它是纯 javascript，不涉及 jQuery。事实上，jQuery 对于这样的工作来说太重了，真的。
function GetURLParameter(sParam)
{
var sPageURL = window.location.search.substring(1);
var sURLVariables = sPageURL.split('&');
for (var i = 0; i < sURLVariables.length; i++)
{
var sParameterName = sURLVariables[i].split('=');
if (sParameterName[0] == sParam)
{
return decodeURIComponent(sParameterName[1]);
}
}
}?
var id = GetURLParameter('id');
var name= GetURLParameter('name');
decodeURIComponent should be used to allow parameter value contain any character, for example the very crucial equals sign =, an ampersand &or a question mark ?.
decodeURIComponent 应该用于允许参数值包含任何字符，例如非常重要的等号=、与号&或问号?。

A simple one if you know the url always has idand name
一个简单的一个，如果你知道网址总是id和name
var url = "www.test.com/index.html?id=1&name=boo";
var id = /id=(\d+)/.exec(url)[1];
var name = /name=(\w+)/.exec(url)[1];

Try this: Working fine in IE and chrome both.Get query string values through javascript
试试这个：在 IE 和 chrome 中都可以正常工作。通过 javascript 获取查询字符串值
$.urlParam = function(name){
var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
if (results == null){
return null;
}
else {
return decodeURI(results[1]) || 0;
}
}
var getData= $.urlParam('emailid');
