<td width="10%" title="双击修改" ondblclick="ShowElement(this,<%#Eval("id") %>
</td>

function ShowElement(element, productid, flag, ishotorcommend) {

    alert("请先设置该产品为推荐");
    return;
  }
  if (flag == 1 && ishotorcommend == 0) {
    alert("请先设置该产品为热销");
    return;
  }
  var oldhtml = element.innerHTML;//原单元格里的值

  var newobj = document.createElement(str);  //创建新的input元素
  newobj.setAttribute("value", oldhtml);//把原来单元格中的值赋给文本框
  newobj.onblur = function() {
    element.innerHTML = this.value &#63; this.value : oldhtml; //当触发时判断新增元素值是否为空，为空则不修改，并返回原有值 
    var sort = element.innerHTML;
