如何使用jquery在表中选择一行？
问题描述：
我在我的应用程序中创建了一个表，我想在单击复选框时选择（更改背景颜色）整行，与gmail一样，当我们在gmail中单击复选框时，整行变为黄色。
I have created a table in my application, I want to select (change background color) whole row on click of a checkbox, same as gmail is doing, When we click checkbox in gmail, the whole row becomes yellow.
<table>
<tbody>
<tr>
<td><input type="checkbox" name="chk" id="chk" /></td>
<td>My Name</td>
<td>Description of the job</td>
</tr>
</tbody>
</table>
请告诉我如何在jquery中做同样的事情？
Please tell me how to do the same in jquery?
答
$(function() {
$("#chk").click(function() {
$(this).parents("tr").toggleClass("diffColor");
});
});
创建一个CSS类（上面称为diffColor）并添加背景颜色，类似于：
Create a CSS class (called "diffColor" above) and add the background color that way, something like:
<style type="text/css">
tr.diffColor td { background-color: yellow; }
</style>
不要直接设置CSS属性。尽可能使用课程。
Don't set CSS attributes directly. Use classes where possible.
