IE9 : DOM Exception: INVALID_CHARACTER_ERR (5)

以下代码在IE8下运行通过，在IE9中出错：
document.createElement('<iframe id="yui-history-iframe" src="../../images/defaults/transparent-pixel.gif" style="position:absolute;top:0;left:0;width:1px;height:1px;visibility:hidden;"></iframe>');
错误提示：exception : SCRIPT5022: DOM Exception: INVALID_CHARACTER_ERR (5)

思路分析：
第一步：兼容IE9，firefox，Opera，Safari等浏览器；
var iframe = document.createElement("iframe");
iframe.setAttribute("id", "yui-history-iframe");
iframe.setAttribute("src", "../../images/defaults/transparent-pixel.gif");
iframe.setAttribute("style","position:absolute;top:0;left:0;width:1px;height:1px;visibility:hidden;");

第二步：兼容IE6-8：由于ie6-8 不能修改iframe的name属性
var oFrame = isIE ? document.createElement("<iframe name=/"" + this._FrameName + "/">") : document.createElement("iframe");
oFrame.name = "iframName";

综合解决办法:

        var isIE = (document.all) ? true : false;//这里仅仅简单的对是否是IE进行判断，详细浏览器判断：请参考浏览器类型侦测
        var ua = navigator.userAgent.toLowerCase().match(/msie ([/d.]+)/)[1];
        if (ua == "9.0") {
            isIE = false;
        }
var oFrame = isIE ? document.createElement("<iframe name=/"" + this._FrameName + "/">") : document.createElement("iframe");
oFrame.name = "iframName";
