本文實例講述了js實現兼容IE、Firefox的圖片縮放代碼。分享給大家供大家參考,具體如下:
function SetSize(obj, width, height) { myImage = new Image(); myImage.src = obj.src; if (myImage.width > 0 && myImage.height > 0) { var rate = 1; if (myImage.width > width || myImage.height > height) { if (width / myImage.width < height / myImage.height) { rate = width / myImage.width; } else { rate = height / myImage.height; } } if (window.navigator.appName == "Microsoft Internet Explorer") { obj.style.zoom = rate; } else { obj.width = myImage.width * rate; obj.height = myImage.height * rate; } }}
用法:
希望本文所述對大家JavaScript程序設計有所幫助。
