How to append a variable to all the javascript files before they are loaded in a page in cake php?

Question

Hello friends,

I need to append a variable to all Javascript files while they are included in a page automatically. The variable needs to be added before the page gets loaded.

Following is the example of what i need.

var scriptfile='http://www.whatever.com/myjs.js?rnd='+revision_number

I need to achieve this using Cake PHP. Please give your suggestions.

Answer 1

I would extend the javascript helper, and write my own custom method to append the string, then call that new method in my layout.

Link, is the method you probably want to overwrite if you don't create a custom one. http://api.cakephp.org/class/javascript-helper#method-JavascriptHelperlink

Answer 2

If revision_number is something you have access to on the server side, you can also set a global variable in your layout and read from that in later scripting or in linked source files.
