Load JS files just before they are needed based on the location of the mouse pointer.
Include the on-demand.js file in your HTML page. Then add something like the following.
document.addEventListener('DOMContentLoaded', function() {
OnDemand.init({ weight: 100 });
OnDemand.addWatch("div-id-1", "scripts/somefile0.js", function(){
alert("scipts/somefile0.js has been added to the page");
});
OnDemand.addWatch("div-id-2", "scripts/somefile1.js", function() {
alert("scripts/somefile1.js has been aded to the page");
});
});The weight that is passed in this example is optional, it defaults to 200. The weight is how many pixels around the element you want to trigger off adding the script to your page.
Then when adding a watch you pass in the id of the element, the file to be loaded, and an optional callback that currently runs just after adding in the new script element. I plan to move this to execute after the script has loaded and been processed.
