Question

我需要找到子元素的位置。

我有一张桌子，当点击一个td时，我想要td的位置（0,1或2）

<table>
<tr>
 <td>   

 </td>
 <td>   

 </td>
 <td>

 </td>
</tr>
</table>

和这样的脚本

<script>
$("td").click(function(){
  //how do i get the position of the td?
  alert("column " + columnPosition + "is clicked")
});
</script>

Answer 1

<script>
$("td").click(function(){
  //how do i get the position of the td?
  alert("column " + $(this).parent().children().index(this) + " is clicked")
});
</script>

编辑：我测试了它，并且它可以正常工作

Answer 2

仅供参考，这很好

<div>First div</div>
<div>Second div</div>
<div>Third div</div>
<div>Fourth div</div>

<script>
 $( "div" ).click(function() {
    // `this` is the DOM element that was clicked
    var index = $( "div" ).index( this );
    $( "span" ).text( "That was div index #" + index );
 });
</script>
