jquery and passing global variables

I have the following:

window.linkFrom;

$(document).ready(function(){

    $("a.linker").click(function(event){

            window.linkFrom = $(this).closest("div").attr("id");

            alert(window.linkFrom); 

            });开发者_如何转开发

 });

and want to pass the var linkFrom to a different script on a second page:

window.linkFrom;

(document).ready(function(){    

            alert(window.linkFrom);

});

How do I make this work?

TIA.

The script environments of two different pages are entirely independent, so you cannot communicate over variables like this. Basically you have two choices:

1. Use cookies.
2. Modify the calls to the second page to add e.g. #linkFrom=asdf to the address and parse that in the js of the second page.
