JavaScript : Get the GET request parameter in script tag

Question

Similar to this question, I would like to get the GET request parameter, but in the script tag itself.

My script tag in HTML <head> is:

<script src="js/script.js?lang=en"></script>

How can I get the lang value ?

jQuery is used and I can obtain the src by:

$('script[src$="/script.js"]').attr('src');

Yes, I solved the issue after few tries, and I think somebody may find it useful. — Raptor, Feb 15 '14 at 03:16
One thing about `data-lang` is that it is only valid in HTML5 — Raptor, Feb 15 '14 at 03:20

To obtain the parameters in <script> tag, we can use:

var lang;
var src = $('script[src~="js/script.js"]').attr('src');
if(src != undefined) {
  lang = src.split("lang=")[1] ? src.split("lang=")[1] : 'yourDefaultValue';
}

Think you probably want `src~="js/script.js"` – megawac Feb 15 '14 at 03:16
