Dynamic loading of JavaScript files

I am working on a JavaScript framework that uses JQueryMobile. The framework can be used for both mobile and non-mobile sites. You can set the page for mobile by calling, for example, enableMobile method. So the framework does not load JS files for JQueryMobile up front. It does so only when enableMobile method is called.

Simple Drag&Drop with JavaScript, JQuery



I am working on an application that requires Drag & Drop functionality in a web page with images.

As it turned out, it is not really very difficult. Here is a simple demo of that implementation.

The original image would be added to the Div.You can then move images within this Div. If you drag and drop it anywhere outside the div, the drop operation is cancelled and image is removed.
