IE9下顯示錯誤沒有 createContextualFragment 方法請在載入ext-all後加入以下js的script <script type="text/javascript">if ((typeof Range !== "undefined") && !Range.prototype.createContextualFragment){ Range.prototype.createContextualFragment = function(html) { var frag = document.createDocumentFragment(), div = document.createElement("div"); frag.appendChild(div); div.outerHTML = html; return frag; };}</script>另外可在之間加入將IE9相容於IE8
