How can I get the url parameter in jquery ready function?

Question

I have the following:

$(document).ready(function() { window.location.href='http://target.SchoolID/set?text='; }); 

So, if someone comes to the page with the above code using the URL, for example:

Somepage.php? ID = ab123

I want the text variable in the finished function to read: abc123

Any ideas?

Answer 1

you don't need jQuery. you can do it with simple js

 function getParameterByName( name ) //courtesy Artem { name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]"); var regexS = "[\\?&]"+name+"=([^&#]*)"; var regex = new RegExp( regexS ); var results = regex.exec( window.location.href ); if( results == null ) return ""; else return decodeURIComponent(results[1].replace(/\+/g, " ")); } 

and then you can just get the querystring value like this:

alert(getParameterByName('text'));
