Getting value GET OR POST variable using JavaScript?

Question

How to get value of the get or post variable on page load using JavaScript?

Answer 1

You can't get the value of POST variables using Javascript, although you can insert it in the document when you process the request on the server.

<script type="text/javascript">
    window.some_variable = '<?=$_POST['some_value']?>'; // That's for a string
</script>

GET variables are available through the window.location.href, and some frameworks even have methods ready to parse them.

Answer 2

You can only get the URI arguments with JavaScript.

// get query arguments
var $_GET = {},
    args = location.search.substr(1).split(/&/);
for (var i=0; i<args.length; ++i) {
    var tmp = args[i].split(/=/);
    if (tmp[0] != "") {
        $_GET[decodeURIComponent(tmp[0])] = decodeURIComponent(tmp.slice(1).join("").replace("+", " "));
    }
}

I just woke up and am very groggy so I may not be clear but you can find anything in the form using the DOM. If x contains the form object, then x.method tells you whether it's POST or GET. x.action is also available.

Or am I misunderstanding? Christmas parties kill me every time.
