Below is my code.

when open the page in ie browser, then select the text in div, the text will be showed by some shadow quad blank . If you delete a line z-index:0, in css class test1, the ie will perform correctly.

In my project , the z-index must be set greater than zero, so I couldn't delete the line.

I found a solution is to set bg_img.filter = "" when pannel.z-index greater than 0, then ie will also working good. But unfortunately, the bg_img.filter.alpha must be set, too.

So how could I do?

      pannel.setAttribute('class', 'test1开发者_如何学C');
      pannel.setAttribute('className', 'test1');

      bg_img.style.cssText = "position:relative;left:0px;top:0px;"
      + "width:198px;"

      head.style.cssText = "position:absolute;"

      document.body.appendChild (pannel);
      pannel.appendChild(bg_img);
      pannel.appendChild(head);

      head.innerHTML = "<div>yusutechasdf</div><div>innerhtml</div>"

IE has problems with z-index: 0; try setting it to one and adjust other z-indexes accordingly.
