jquery删除选定的表格行背景颜色

Question

如何在 jquery 的帮助下去除选中行的背景色？

假设用户选择了 id=3 的行，我需要删除背景颜色。

<table class='css_table' style='width: 100%'>
<tr>
    <th style='width: 20%'>Kimden</th>
    <th style='width: 25%'>Konu</th>
    <th style='width: 25%'>Mesaj</th>
    <th style='width: 10%'>Okundu</th>
    <th style='width: 20%'>Tarih</th>
</tr>
<tr id='3' class='selected_row' style='cursor: pointer; background-color: #E0EEEE'>
    <td><span class='row_name'>Prof. Dr.altay tinar</span></td>
    <td><span class='row_subject'>asda da dasd asdasda</span></td>
    <td><span class='row_body'>asda da dasd asdasda</span></td>
    <td><span>0</span></td>
    <td><span class='row_time'>4/15/2013 3:40:40 AM</span></td>
</tr>
<tr id='5' class='selected_row' style='cursor: pointer;'>
    <td><span class='row_name'>Ped.Arifx Yilmazx</span></td>
    <td><span class='row_subject'>undefined asd asdsa </span></td>
    <td><span class='row_body'>qdqw dqw d asda sd </span></td>
    <td><span>1</span></td>
    <td><span class='row_time'>4/15/2013 3:42:36 AM</span></td>
</tr>

Answer 1

使用jQuery's css function去除背景色值：

var selectedId = 3;
$("#" + selectedId).css("background-color", "");
