Script tags with src and code between script tags

Question

Is the following valid javascript? Would the variable be available to the externally called script?

Answer 1

No, it's not possible to do what you're doing directly. However there's a clever little hack you can employ to enable it: http://ejohn.org/blog/degrading-script-tags/

Consider the following HTML snippet:

Add the following code to the end of your external.js file:

var scripts = document.getElementsByTagName("script");
var length = scripts.length;
var script = scripts[length - 1].innerHTML;
eval(script);

Note however that eval must be called indirectly so that the script is executed in the global scope.
