使用jQuery获取每个表行的ID

Question

很抱歉缺少代码,但我只需要有人指明方向并帮我提供一个each()声明来提醒每个TR的ID.

$( document ).ready(function() {

  /* alert each TR's ID from #theTable */

});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<table id="theTable">
  <tr id="id1"></tr>
  <tr id="id2" class="theClass"></tr>
  <tr id="id3"></tr>
</table>

Answer 1

使用each()方法和获取id元素的属性.

$(document).ready(function() {
  $('#theTable tr').each(function() {
    console.log(this.id)
  })
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<table id="theTable">
  <tr id="id1"></tr>
  <tr id="id2" class="theClass"></tr>
  <tr id="id3"></tr>
</table>
