如何在没有删除输入的情况下清空td的值？

Question

我想要删除自定义td的值。

<td> <input type="hidden" name="myinput" value="1"> some text </td>

我不想删除输入，只想删除一些文本。有什么帮助？

Answer 1

然后只调用textContent方法

来更新text

例如，

//$("td").text(""); //Doesn't work

//$("td")[0].textContent = ""; //Doesn't work

//convert childNodes to Array and then iterate through the same
Array.prototype.slice.call( $("td")[0].childNodes ).forEach(function(node){
  node.nodeType == 3 && node.parentNode.removeChild(node); //if the node is a text node then remove the same
});

<table>
  <tr>
    <td>
      <input type="hidden" name="myinput" value="1">some text</td>
  </tr>
</table>

{
    ... // your JSON properties here
    "serviceProperties": { // properties for service

        "Certificates": false,
        "DocumentName": "note.pdf"
