Right-click the variable that you want to duplicate and select Copy.
The dollar sign ($) and the underscore (_) characters are JavaScript identifiers, which just means that they identify an object in the same way a name would. The objects they identify include things such as variables, functions, properties, events, and objects.
Objects are assigned and copied by reference. In other words, a variable stores not the “object value”, but a “reference” (address in memory) for the value. So copying such a variable or passing it as a function argument copies that reference, not the object itself.
var $_GET = {};
if(document.location.toString().indexOf('?') !== -1) {
var query = document.location
.toString()
// get the query string
.replace(/^.*?\?/, '')
// and remove any existing hash string (thanks, @vrijdenker)
.replace(/#.*$/, '')
.split('&');
for(var i=0, l=query.length; i<l; i++) {
var aux = decodeURIComponent(query[i]).split('=');
$_GET[aux[0]] = aux[1];
}
}
//get the 'index' query parameter
alert($_GET['index']);
