Jquery image size (height and width) Example

Getting the image size in jquery is actually an application for obtaining the image height and width. We only need to use attr to load the ID. Here are two examples.

Example

The Code is as follows:	Copy code
Var pic_real_width, pic_real_height; $ (". Attr ("src", $ (img). attr ("src ")) . Load (function (){ Pic_real_width = this. width; // Note: $ (this). width () will not Pic_real_height = this. height; // work for in memory images. });

Or

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