JQuery url GET变量

Question

I there a possible way to use a GET variable in jQuery url. Like in PHP we have something like this:

header('location : path/to/page.php?id='.$id);

And In the page.php we do this:

$id = $_GET['id'];

So in jQuery can we do something like:

window.location.replace(path/to/page.html/* and pass the url query here*/);

I think what you are looking for is to access the query string ($_GET in php) variables in javascript. You can use this function for that.

function getParameterByName(name, url) {
    if (!url) url = window.location.href;
    name = name.replace(/[\[\]]/g, "\\$&");
    var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
        results = regex.exec(url);
    if (!results) return null;
    if (!results[2]) return '';
    return decodeURIComponent(results[2].replace(/\+/g, " "));
}

and then call getParameterByName('id') to get ?id=val part of the current URL.
