Javascript window.open 被 IE 弹出窗口阻止程序阻止

Can anyone help, I have a popup that is being blocked. It is a popup that is created because somebody has clicked on a Print picture on my site.

I thought IE is not supposed to block these when the popup came via an onclick?

Can anyone help? The child1 variable is always returned as NULL if popup blocker enabled...

Maybe the problem is that the onclick event then passes control to a new function which loads a html file and does child.document.write

Here is my simple code..

var width = 800;
var height = 600;
var left = parseInt((screen.availWidth / 2) - (width / 2));
var top = parseInt((screen.availHeight / 2) - (height / 2));
var windowFeatures = "width=" + width + ",height=" + height 
   + ",menubar=yes,toolbar=yes,scrollbars=yes,resizable=yes,left=" 
   + left + ",top=" + top + "screenX=" + left + ",screenY=" + top;      

child1 = window.open("about:blank", "subWind", windowFeatures);

The problem will be that open will only return a reference to the window if you are navigating to somewhere within your current host. You are navigating to about:blank which is not within your host.

Try adding a blank.htm file to your site and open that instead. I'm still not sure that document.write will be allowed the document won't be open for write, you may be able to manipulate the DOM of the existing blank document though.
