<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’>
