Obtain the license plate specifications to unify, otherwise it is difficult to grasp the license plate positioning this piece.2. The key to cutting characters is to let the program determine the location of the license plate, so it is more convenient to cut. The problem is that it takes a bit of time to get f

For example, to have the page scroll smoothly to an element with an ID of box, the jquery code is as long as one sentence, the key position is as follows:$ ("Html,body"). Animate ({scrolltop:$ ("#box"). Offset (). top},1000)Where Animate is a custom animation method for jquery, $ ("#box"). Offset (). Top indicates that a jquery object with the ID of box is offset from the top of the page, and 1000 indicates tha
