<g:image id="controlImage" style="position:absolute; " onclick="controlImageClick();" />
请问这是什么意思呀？：（
<div id= "playbackControls ">
<g:image id= "controlImage " style= "position:absolute; " onclick= "controlImageClick(); " />

</div>
如果一个层里要插入图片不就直接是 <image> 吗？
怎么要 <g:image ??
难道是要JS中控制吗？？

This example shows how to use the src and rotation properties in script.

var oImage = document.getElementById(“myImage”);
oImage.src = “prettyPicture.png”;
oImage.rotation = 30; // degrees

This example shows you how to use g:image in HTML code.

<g:image id=’myImage’>
