实际生产过程中，我们往往有需要获得一个被压缩的图片的真实原始大小。此时我们可以用下面这个代码来实现： [js] // Get on screen image var screenImage = $("#image"); // Create new offscreen image to test var theImage = new Image(); theImage.src = screenImage.attr("src"); // Get accurate measurements from that. var imageWidth = theImage.width; var imageHeight = theImage.height; [/js]
