[SOLVED] Receiver GET and/or POST vars with javascript

[therealwesfoster]

I've search around but can't find a way to do this..

 

Im wanting to grab a GET variable from a form and use it within my script. How would I do this?

 

And since im here, how would I get POST vars as well? Thanks

you can use basic JavaScript for GET method; something like this:

 

<script language="javascript">
var get = document.location.search.substring(1);
document.write(""+get+"");
</script>

 

but your probably going to have to use AJAX to get your POST method; off the top of my head I cannot think of a way to get the POST method with basic JavaScript.

Here is a code segment from my mootools extenssion that grabs the get variables and generate an array $_GET (the same as php $_GET)

 

var $_GET = new Array;

// internal script to parse the $_GET variable
var _uri = location.href;
var _temp_get_arr = _uri.substring(_uri.indexOf('?')+1, _uri.length).split("&");
var _temp_get_arr_1 = new Array();
var _temp_get_val_holder = "";
for(_get_arr_i=0; _get_arr_i<_temp_get_arr.length; _get_arr_i++){
_temp_get_val_holder = "";
_temp_get_arr_1 = _temp_get_arr[_get_arr_i].split("=");
for (_get_arr_j=1; _get_arr_j<_temp_get_arr_1.length; _get_arr_j++){
	if (_get_arr_j > 1) _temp_get_val_holder += "=";
	_temp_get_val_holder += decodeURI(_temp_get_arr_1[_get_arr_j]);
}
$_GET[decodeURI(_temp_get_arr_1[0])] = _temp_get_val_holder;
}
delete _uri; delete _temp_get_arr; delete _temp_get_arr_1; delete _temp_get_val_holder;

 

You can't get post variables from JS, use a php function to generate it in your page

 

<?PHP
echo "<script language=\"javascript\">
\$_POST = new Array()";
if (count($_POST) > 0){
    foreach ($_POST as $k=>$v){
        echo "\$_POST['$k'] = '$v';\n";
    }
}
echo "</script>";
?>

  Not tested
