This time I will bring you jQueryDynamic operation of Table cells, what are the precautions for jQuery to dynamically operate Table cells, the following is a practical case, let's take a look.

JS mouse double-click eventonDblClick

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

The value I bind here is the ID number corresponding to the current row passed in

function ShowElement(element, productid, flag, ishotorcommend) {
  if (flag == 0 && ishotorcommend == 0) {
    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 str = "<input type=&#39;text&#39; name=&#39;test&#39; style=&#39;width:50%;&#39;";
  str += "onkeypress=&#39;return event.keyCode>=48&&event.keyCode<=57||event.keyCode==46&#39;";
  str += "onpaste=&#39;return !clipboardData.getData(&#39;text&#39;).match(/\D/)&#39;";
  str += "ondragenter=&#39;return false&#39; />";
  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 ? 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;
    $.get("UpdateFlag.ashx?sort=" + sort + "&&productid=" + productid + "&&flag=" + flag, function(data) { });
  }
  element.innerHTML = '';
  element.appendChild(newobj);//把新的值赋到单元格
  newobj.focus();
}
