I done this so far and not getting idea what to do next:

url.match(?);
Can some body help.Thanks

Have a look at the MDN article about window.location.
The QueryString is available in window.location.search.
MDN also provide an example of how to the get value of a single key available in window.location.search.
Something like this:
function loadPageVar (sVar) {
return unescape(window.location.search.replace(new RegExp("^(?:.*[&\?]" + escape(sVar).replace(/[.+*]/g, "\$&") + "(?:\=([^&]*))?)?.*$", "i"), "$1"));
}
// Would alert the value of QueryString-variable called name
alert(loadPageVar("name"));

Use window.location.search to get everything after ? including ?
Example:
var url = window.location.search;
url = url.replace("?", ''); // remove the ?
alert(url); //alerts ProjectID=462 is your case
