我的html页面中有一个图片标签.

推荐答案

首先设置具有空白图像(如1 x 1像素的白色图像)的图像标签.
然后使用Javscript

您需要为此使用javascript:

First set Image Tag with a blank image like 1 x 1 pixel white image.
Then use Javscript

You''ll need to use javascript for this:

<img src="white.jpg" id="RunTimemage" />

<script type="text/javascript">
  document.getElementById("RunTimeImage").src = "image3.jpg";
</script>

如果需要，您也可以切换其可见性:
声明它不可见.

Also you can toggle its visibility too if you want:
Declare it invisible.

<img src="" style="visibility:hidden"></img>

使其可见:

Make it visible:

document.getElementById(RunTimeImage).style.visibility = 'hidden';
