jquery如何选择每个表行的第一个单元格

Question

I have a table like this:

<table id="myTable">
   <tr><td>1sta</td><td>2nd</td></tr>
   <tr><td>1stb</td><td>2nd</td></tr>
   <tr><td>1stc</td><td>2nd</td></tr>
   <tr><td>1std</td><td>2nd</td></tr>
</table>

Using jQuery How do I select the 1st <td> element in each row of "myTable"?

Answer 1

The first-child selector grabs each td that is the first child of its parent (the tr in this case).

$('#myTable td:first-child');

Answer 2

Use this selector '#myTable td:first-child' .

That will select the first td for every tr . Avoid the temptation to use :first instead of :first-child . :first will only select a single element. In this case it would be the first cell of the first row.
