Example of jquery Image height and width acquisition

Simple principle

After the image is loaded, we use attr to load a tag for the image, and then we get the width and height of the image.

The code is as follows:	Copy code
Var img = $ ("# imgID"); // Obtain the img element Var picRealWidth, picRealHeight; $ ("") // Create an img tag in the memory . Attr ("src", $ (img). attr ("src ")) . Load (function (){ PicRealWidth = this. width; PicRealHeight = this. height; });
