DWZ的创建表单元素问题

我用js动态创建一些表单元素,代码如下:<div id="FileList">
            <p>
<label>项目名称：</label>
                <input type="hidden" name="orgLookup.id" value="${orgLookup.id}"/>
<input type="text" class="" name="dwz_orgLookup.orgName" value="" readonly="readonly"/>
                <a class="btnLook" href="<%=Url.Action("UserOrgLookup", "Admin")%>" lookupGroup="" lookupName="orgLookup" maxable="false" resizable="false"><hi:text key="查找带回"/></a>
                <a href="javascript:;" onclick="AddFile();">[+]</a>
            </p>
            </div>var index = 1;
    function AddFile() {
        var ul = document.getElementById("FileList");
        var inputDiv = document.createElement("p");
        //inputDiv.setAttribute("Id", "P" + index);
        var leabl = document.createElement("label");
        leabl.innerHTML = "项目名称：";
        var file = document.createElement("input");
        file.setAttribute("type", "text");
        file.setAttribute("class", "textInput required");
        file.setAttribute("readonly", "readonly");
        file.setAttribute("id", "dwz_orgLookup" + index+".orgName");
        file.setAttribute("name", "dwz_orgLookup" + index+".orgName");
        var select = document.createElement("a");
        select.setAttribute("class", "btnLook");
        select.setAttribute("href", "<%=Url.Action("UserOrgLookup", "Admin")%>");
        select.setAttribute("lookupGroup", "");
        select.setAttribute("lookupName", "orgLookup" + index);
        select.setAttribute("maxable", "false");
        select.setAttribute("resizable", "false");
        select.innerHTML = "<hi:text key=\"查找带回\"/>";
        var btnDel = document.createElement("a");
        btnDel.setAttribute("href", "javascript:;");
        btnDel.innerHTML = "[-]";
        btnDel.setAttribute("Id", index);
        btnDel.onclick = function () {
            inputDiv.removeChild(file);
            inputDiv.removeChild(btnDel);
            ul.removeChild(inputDiv);
        }
        inputDiv.appendChild(leabl);
        inputDiv.appendChild(file);
        inputDiv.appendChild(select);
        inputDiv.appendChild(btnDel);
        ul.appendChild(inputDiv);
        index++;
    }创建成功后的表单元素,点击查找带回,结果不跳窗了...郁闷了...也就是说完全读不到外部JS了,CSS倒是能读到...
