| Post subject: | a handy javascript function for getting GET vars |
hey, I found this online somewhere and thought I'd share. I make prolific use of GET vars where it makes sense (you can bookmark a GET, after all), and I make prolific use of javascript for AJAX, but getting a GET var with javascript can be a pain. This function does it for you. [php] function gup(name){ var regexS = "[\\?&]"+name+"=([^&#]*)"; var regex = new RegExp( regexS ); var tmpURL = window.location.href; var results = regex.exec( tmpURL ); if( results == null ) return ""; else return results[1]; } [/php] just pass it the name of the var you want and it'll send back the value. VERY handy. [php] function whatever(){ document.getElementById('PigIsTheCoolest').innerHTML = gup('PigGetVar'); } [/php] |
