下面是對(duì)一些數(shù)字進(jìn)行格式化
我們想改變這么一段代碼中間td之間的文本
<table>
<tr id='generated_rows'>
<td class='row_class' id='row_id_1'>1</td>
<td class='row_class' id='row_id_2'>2</td>
<td class='row_class' id='row_id_3'>3</td>
<td class='row_class' id='row_id_4'>4</td>
<td class='row_class' id='row_id_5'>5</td>
</tr>
</table>

實(shí)現(xiàn)顯示為：

<table>
<tr id='generated_rows'>
<td class='row_class' id='row_id_1'>1.00</td>
<td class='row_class' id='row_id_2'>2.00</td>
<td class='row_class' id='row_id_3'>3.00</td>
<td class='row_class' id='row_id_4'>4.00</td>
<td class='row_class' id='row_id_5'>5.00</td>
</tr>
</table>
實(shí)現(xiàn)的函數(shù)為：
$('#generated_rows td.row_class').each(function() {
var x = Number($(this).text()).toFixed(2);
$(this).text(x);
});
演示代碼
