The examples I've seen online seem much more complex than I expected (manually parsing &/?/= into pairs, using regular expressions, etc). We're using asp.net ajax (don't see anything in their client side reference) and would consider adding jQuery if it would really help.
I would think there is a more elegant solution out there - so far this is the best code I've found but I would love to find something more along the lines of the HttpRequest.QueryString object (asp.net server side) . Thanks in advance,

确实有一个jQuery的QueryString插件 ,如果你愿意安装jQuery核心和插件它可能证明是有用的。
I am using this function in case i don't want to use a plugin:
function getQueryVariable(variable) {
var query = window.location.search.substring(1);
var vars = query.split("&");
for (var i = 0; i < vars.length; i++) {
var pair = vars[i].split("=");
if (pair[0] == variable) {
return pair[1];
}
}
return null;
}
Take a look at my post, as it tells you exactly how to do this:

For jQuery I suggest jQuery BBQ: Back Button & Query Library By "Cowboy" Ben Alman
jQuery BBQ leverages the HTML5 hashchange event to allow simple, yet powerful bookmarkable #hash history. In addition, jQuery BBQ provides a full .deparam() method, along with both hash state management, and fragment / query string parse and merge utility methods.
Example:
// Parse URL, deserializing query string into an object.
// http://www.example.com/foo.php?a=1&b=2&c=hello#test
// search is set to ?a=1&b=2&c=hello
// myObj is set to { a:"1", b:"2", c:"hello" }
var search = window.location.search;
var myObj = $.deparam.querystring( search );
*$(document).ready(function () {
$("#a").click(function () {
window.location.href = "secondpage.aspx?id='0' & name='sunil'& add='asr' & phone='1234'";
});
});*
**then read the query string parameters on another using split method . Here as follows:**
*$(document).ready(function () {
var a = decodeURI(window.location.search);
var id = window.location.search = "id=" + $().val();
var name = a.split("name=")[1].split("&")[0].split("'")[1];
var phone = a.split("phone=")[1].split("&")[0].split("'")[1];
var add = a.split("add=")[1].split("&")[0].split("'")[1];
alert(id+','+name+','+add+','+phone);
});*
If there's any possibility of encountering repeated parameters (eg ?tag=foo&tag=bar), most libraries out there won't be sufficient. In that case, you might want to consider this library that I developed from Jan Wolter's very comprehensive parser . I added .plus() and .minus() functions and roundtripping:
https://github.com/timmc/js-tools/blob/master/src/QueryString.js
Use the String utility from prototypejs.org, called toQueryParams().
Example from their site: http://prototypejs.org/api/string/toQueryParams
'section=blog&id=45'.toQueryParams();
// -> {section: 'blog', id: '45'}'section=blog;id=45'.toQueryParams();
// -> {section: 'blog', id: '45'}' http://www.example.com?section=blog&id=45#comments '.toQueryParams();
// -> {section: 'blog', id: '45'}'section=blog&tag=javascript&tag=prototype&tag=doc'.toQueryParams();
// -> {section: 'blog', tag: ['javascript', 'prototype', 'doc']}'tag=ruby%20on%20rails'.toQueryParams();
// -> {tag: 'ruby on rails'}'id=45&raw'.toQueryParams();
// -> {id: '45', raw: undefined}
Also, you may use the alias parseQuery() to obtain the same results.
window.location.search.parseQuery();
Since window.location returns an object, you must obtain the string.
