IE9下Coolite.Ext出现createContextualFragment错误

解决Ext在IE9上报错“createContextualFragment”，只需要在使用Coolite.Ext页面加入如下代码即可：

if ((typeof Range !==
"undefined") && !Range.prototype.createContextualFragment)
{
       
Range.prototype.createContextualFragment = function(html) {
           
var frag = document.createDocumentFragment(),
               
div = document.createElement_x("div");
           
frag.appendChild(div);
           
div.outerHTML = html;
           
return frag;
       
};
    }
