我做了一个照片概念的演示,在两个图像之间切换以显示它们之间的差异.

我有一个onMouseClick事件工作正常,除了在iPad上.我的桌面上的响应是即时的,但平板电脑上的延迟可能是500毫秒？

这是正常的吗？还有另一种方法可以解决这个问题吗？

使用Javascript:

var img1 = new Image();
img1.src = "http://watkinsfilm.com/wp-content/uploads/2012/09/19mm.jpg";

var img2 = new Image();
img2.src = "http://watkinsfilm.com/wp-content/uploads/2012/09/200mm.jpg";


function test() {
    if (document.pic.src == 'http://watkinsfilm.com/wp-content/uploads/2012/09/19mm.jpg') {

        document.pic.src = 'http://watkinsfilm.com/wp-content/uploads/2012/09/200mm.jpg';
    }
    else if (document.pic.src == 'http://watkinsfilm.com/wp-content/uploads/2012/09/200mm.jpg') {

        document.pic.src = 'http://watkinsfilm.com/wp-content/uploads/2012/09/19mm.jpg';
    }
}?

身体:

 <div>
   <table id="table-1" >
   <tr><td>
      <img id="img" src="http://watkinsfilm.com/wp-content/uploads/2012/09/19mm.jpg" name="pic" onMouseDown="test()"/>
       <img id="png1" src="http://www.thedigitaltrekker.com/wp-content/uploads/2012/03/logo-6smA.png"/>
Click on the image above to toggle between 19mm and 200mm <br>
   </td></tr>
   </table>
</div>
?
