是否可以在外部.js文件中引用我的代码隐藏变量？

Question

I'm cleaning up some old projects and moving the javascript from my .aspx pages to an external javascript file.

In a few of my pages, I reference variables from the C# side in my javascript. For example:

var myVal = <%= idNumber %>;

where idNumber is a public variable set in my codebehind.

This no longer works when I move the script to an external file, which makes sense. I thought explicitly stating window.idNumber might work, but I was incorrect.

Is there a way to make this work? If not, what is the best practice? Should I keep the js similar to this example in the page itself and call "external" methods? Can I assign a .js file to a specific page and only that page (just to keep my code clean)?

Any advice would be greatly appreciated

I ran into this problem a while back as well. My solution was to re-factor my JS code to use function parameters and then have my code-behind call the functions. This has the added benefit that it makes your JS code more re-usable.
