Wouldn't it be nice if you could pass parameters to your JavaScript file? Well, it turns out you can.
I have tested the method described here in Chrome, FireFox, InternetExplorer, and Safari.
index.html
<!DOCTYPE html>
<html>
<head>
<title>Arguments Demo</title>
<script src="arguments.js" spinner="spinner.png"></script>
</head>
<body>
</body>
</html>
arguments.js
if(!NSArguments) {
var Arguments = function() {
var self = {
script: document.currentScript || document.scripts[document.scripts.length-1]
};
var that = {};
that.getArgument = function(name) {
return self.script.getAttribute(name);
};
return that;
};
var NSArguments = Arguments();
}
(function(){
window.addEventListener("load", function() {
var spinner = NSArguments.getArgument("spinner");
console.log(spinner);
});
}());
The output in the console will be:
