The code copy is as follows:
/* Get the address bar GET parameters like PHP's $_GET['arg'] */
function getArgs() {
var args = {};
var query = location.search.substring(1); // Get query string
var pairs = query.split("&");
// Break at ampersand
for(var i = 0; i < pairs.length; i++) {
var pos = pairs[i].indexOf('=');
// Look for "name=value"
if (pos == -1) continue; // If not found, skip
var argname = pairs[i].substring(0,pos); // Extract the name
var value = pairs[i].substring(pos+1); // Extract the value
value = decodeURIComponent(value); // Decode it, if needed
args[argname] = value; // Store as a property
}
return args; // Return the object
}

alert( getArgs()['user'] );// Output funsion
alert( getArgs()['age'] );// Output 26
