[Program principle] The following uses simpledrag as an example to describe the basic principle. First, you need a drag-and-drop object in the initialization program:This. Drag = $ (drag );Two parameters are also required to record the coordinates of the mouse relative to th

drag-and-drop operation sometimes achieves the effect of dragging the content in the source component to the target component, this effect is "Move".

Now this drag if I move the mouse faster, you will find this mouse from this div out, this time Div will not follow the mouse away. So why does this p

Some advanced applications of Javascript drag-and-drop-by-line code analysis make it easy for you to drag the code line by line.
