JavaScript $_GET

[Xephra]

This is my equivalent of PHPs $_GET.

It's basic, I might do some other things soon.


<script>
function jsGet(type){
if(location.href.match(type)){
return location.href.split(type+'=')[1].split('&')[0];
}}
</script>


Example Useage:


document.write(jsGet('action'));


To show the current action.

If you are trying to emulate PHP's $_GET, then maybe something like this would work better...

var $_GET = new Object();
var $qry_str = location.search.substring(1);
var $k = 0;

do {
    $_GET[$qry_str.split("=")[0].replace(/&/, "")] = $qry_str.split("=")[1].split(/&|$/)[0];
    $qry_str = $qry_str.split($qry_str.split("=")[1].split(/&|$/)[0])[1];
    $k ++;
} while($k < (location.search.split("=").length - 1));

for(key in $_GET){
    alert("Variable: " + key + "\nValue: " + $_GET[key]);
}

Haha...I was thinking of doing a more advanced one, and some other things similar. Nice code. =)

I didn't realize that $ was a valid character in JavaScript variables

Yup. Its kind of bizarre (sp?) if you ask me.

My var version (just a few changes):
var $_GET = {};
vars_area = location.search.substring(1);

if(vars_area.length > 2)
{
   get_sets = query_str.split("&");
   for(i = 0, num_gets = get_sets.length; i < num_gets; i++)
   {
      parts = get_sets[$i].split("=");
      $_GET[unescape(parts[0])] = unescape(parts[1]);
   }
}

My function version:
function getGetVar(searchStr)
{
   start = location.search.indexOf(searchStr)+searchStr.length+1;
   end = (location.search.indexOf('&', start) == -1)? location.search.length : location.search.indexOf('&', start);
   return unescape(location.search.substring(start, end));
}

Just one one Note i used this about 2 years ago and then came across needing it again today but it fails validation due to it creating an error if there are not any url variables
So i fixed it for you hehe:

var $_GET = new Object();
var $qry_str = location.search.substring(1);
var $k = 0;

if($qry_str.split("=")[1]){
do {
   $_GET[$qry_str.split("=")[0].replace(/&/, "")] = $qry_str.split("=")[1].split(/&|$/)[0];
   $qry_str = $qry_str.split($qry_str.split("=")[1].split(/&|$/)[0])[1];
   $k ++;
} while($k < (location.search.split("=").length - 1));
}

Just added the if around it if($qry_str.split("=")[1]){
