jQuery: Using window url parameter
Let’s say we have passed a parameter to URL: www.mysite.com/?page=test
To collect the data form parameter we can use this function:
function getUrlParameter(name) { name = name.replace(/[\[]/, '\\[').replace(/[\]]/, '\\]'); var regex = new RegExp('[\\?&]' + name + '=([^&#]*)'); var results = regex.exec(location.search); return results === null ? '' : decodeURIComponent(results[1].replace(/\+/g, ' ')); };
use of this code:
getUrlParameter('page');
or
if (getUrlParameter('page') == 'test'){ // do something }
