Read javascript .js get parameters

Question

How can I read get parameters passed to a JS file like so:

<script type="text/javascript" src="/script.js?p1=hello&p2=world"></script>

In the same file (script.js) I want to read the p1 and p2 values like:

var p1 = params["p1"];

I'd rather avoid a method that getElementById's or uses the dom anyway. thanks.

Would it be possible for you to make a PHP wrapper that echoes the get parameters into the .js file? — pimvdb

No magic that I'm aware of here... As the script is loaded, the tag is added to the dom tree and you can read from it using document.getElementsByTagName('script') and then parse the results.

Thanks, I wanted to make sure there wasn't anything similar to window.location that pertains to the .js file itself. Used getElementById eventually.

See this answer. You then have to parse the result yourself.

This will not work, cause script[i].src contains full URL with all params, so you don't have loop through all scripts' srcs if you already know query string
