Analyzing GET request with JavaScript

GET requests (using address bar) can be easily analyzed with JavaScript. I’ll demonstrate this with the following example: write in the address bar any parameter in the format ?parameter=value&parameter=value...

Variables of the GET request: 

var tmp = new Array(); // two auxiliary
var tmp2 = new Array(); // arrays
var param = new Array();
 
var get = location.search; // string of the GET request
if( get != '' ) {
  tmp = ( get.substr( 1 ) ).split( '&' ); // split variables
  for( var i=0; i < tmp.length; i++ ) {
    tmp2 = tmp[ i ].split( '=' ); // array param will contain
    param[ tmp2[ 0 ] ] = tmp2[ 1 ]; // param key(name of the variable)->value
  }
  var obj = document.getElementById( 'greq' ); // screen output
  for( var key in param ) {
    obj.innerHTML += key + " = " + param[ key ] + "<br>";
  }
}

The key value is location.search (see article on base tag).
