Change value of 'meta' in link css after onload

I have a problem.

I'm trying to use asynchronous CSS loading to optimize my graphic elements.

In the <head> of my html I have several links of .css (example:)

<link id="cs1" rel="stylesheet" href="css/ZooCss.css" media="none" onload="cambiarMedia()"/>

The cambiarMedia() function is above the links:

<script type="text/javascript">
    function cambiarMedia() {
        if (document.getElementById("cs1").getAttribute('media') === 'none') {
            document.getElementById("cs1").setAttribute('media', 'all');
        }
    }
</script>

Basically what I want you to do is change the value from meta to all . The problems that I crash with:

Just like the function cambiarMedia Visual Studio throws me the following error:

'ASP.default_aspx' does not contain a definition of cambiarMedia nor is found any extension method cambiarMedia that accepts a first argument of type 'ASP.default_aspx' (missing a directive using or an assembly reference?)

If I solve this error, I would also like to transform the cambiarMedia function so that it is reusable for all CSS's. Not to rewrite it for each CSS ID.

Can you give me a hand with that please?
