Is there a way to embed one JavaScript file into another so that it can be referenced? I'm looking for the JavaScript equivalent of include() in PHP.
Many people have suggested using this method:
document.write('<script type="text/javascript" src="globals.js"></script>');
However, I am unsure if this is similar to include().
Take a look at http://requirejs.org/. It allows you to define (AMD) modules and easily reference them in other modules like this:
define(["path/to/module1", "path/to/module1")], function(Module1, Module2) {
//you can now access the modules
});
Avoid using document.write as it may cause the entire page to be erased if content has already been written. Instead, consider implementing a simple solution like the following:
var newScript = document.createElement('script');
newScript.type = 'type/javascript';
newScript.src = '/dir/somefile.js'; // path to the js file you want to include
var insertionPointElement = document.getElementsByTagName('script')[0]; // this could be the first javascript tag or any other element
insertionPointElement.parentNode.insertBefore(newScript, insertionPointElement);
