div动态生成

.hidenDiv{filter:Alpha(Opacity=50);
position:absolute;
z-index:101;
left:0px;
top:0px;

}

<div id="main"></div>
<div id="div1" class="hidenDiv"><IMG width="100%" src="./images/blue_back.png" ></div>

如何用js动态生成div1这个层

Answer 1

<div id="main">rr</div>

<script language="JavaScript">
var vIMG = document.createElement("IMG ");
vIMG.setAttribute("width", "100%");
vIMG.setAttribute("src", "./images/blue_back.png");

var vDIV = document.createElement("DIV");
vDIV.appendChild(vIMG);
vDIV.setAttribute("className","middle");
document.getElementById("main").innerHTML = vDIV.innerHTML;
</script>

document.all.div1.style.display='';

document.all.div1.style.display='none';
