请看下面的IE代码：

var ie =（（document.all）？true：false）;

var ElementUtil = new Object（）;

ElementUtil.addEventListener = function（o，type，handler）{

ElementUtil.addEventListener（img，drag，函数（）{return false;}）;

I am trying to implement a rubber band/image selection script. For
that I need to remove the default drag behaviour on an image. I am
able to do this in IE but not Netscape. Does any one have a solution?

Pls look below for IE code:

var moz = ((document.all)? false : true);
var ie = ((document.all)? true : false);
var ElementUtil = new Object();
ElementUtil.addEventListener = function(o, type, handler) {
if(ie) {
o.attachEvent("on" + type, handler);
}
else if(moz) {
o.addEventListener(type, handler, false);
}
}

// Removes default drag behaviour on image in ie
ElementUtil.addEventListener(img, "drag", function() {return false;});

Thanks in advance

感谢Martin，这正是我想要的。有没有

的网站，我们可以参考Netscape的对象模型（属性，

方法，事件......）？

Thanks Martin, this is exactly what I was looking for. Is there any
website where we can refer Netscape''s object model (properties,
methods, events...)?
