You can put anything that you want in a <script> tag.

No, they’re not needed, in fact you’ll get a syntax error if you include them. Your .js files should contain only JavaScript, no HTML tags around it, like would have inside a page.

I apologise for replying to a super old question but after spending an hour wrestling with the above solutions I opted for simpler stuff. <script src=”https://stackoverflow.com/questions/5292372/..” one=”1″ two=”2″></script> Inside above script: document.currentScript.getAttribute(‘one’); //1 document.currentScript.getAttribute(‘two’); //2 Much easier than jquery OR url parsing.

You can’t load JSON like that, sorry. I know you’re thinking “why I can’t I just use src here? I’ve seen stuff like this…”: <script id=”myJson” type=”application/json”> { name: ‘Foo’ } </script> <script type=”text/javascript”> $(function() { var x = JSON.parse($(‘#myJson’).html()); alert(x.name); //Foo }); </script> … well to put it simply, that was just the script … Read more
How about adding a new script tag to <head> with the script to (re)load?

You may need to add … Read more
