Question

我正在尝试选择某个类的表的偶数行。

所以表格如下：

Absolute row 1 -- virtual row 1 of class a
Absolute row 2 -- virtual row 2 of class a (should be matched by css selector)
Absolute row 3 -- virtual *row 1* of class b
Absolute row 4 -- virtual row 3 of class a
Absolute row 5 -- virtual row 4 of class a (should be matched by css selector)

我尝试使用此选择器：

.table-result tbody tr.include:nth-child(even) {background-color: #eeeeee;}

但是它仍然保持着不同类的想法

有解决方法吗？无需求助于表格中的表格？

HTML：

    <table class="ui-widget ui-widget-content table-result" id="adspaceresult">
        <thead>
            <tr class="ui-widget-header">
                <th>Type</th>

                <th>Info</th>

                <th>Average</th>

                <th>Bid</th>

                <th>Graph</th>
            </tr>

        </thead>

        <tbody id="adrbody">
            <tr class="include">
                <td><button data-adtype="1" data-adspaceid="2" class="resultbutton ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" role="button"><span class="ui-button-text">Micro Bar<br>
                88x31</span></button></td>

                <td></td>

                <td>77</td>

                <td>Bid</td>

                <td>Graph</td>
            </tr>

            <tr>
                <td colspan="5">Why hello there!</td>
            </tr>

            <tr class="include">
                <td><button data-adtype="1" data-adspaceid="3" class="resultbutton ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" role="button"><span class="ui-button-text">Micro Bar<br>
                88x31</span></button></td>

                <td></td>

                <td>748102</td>

                <td>Bid</td>

                <td>Graph</td>
            </tr>

            <tr class="include">
                <td><button data-adtype="1" data-adspaceid="5" class="resultbutton ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" role="button"><span class="ui-button-text">Micro Bar<br>
                88x31</span></button></td>

                <td></td>

                <td>226</td>

                <td>Bid</td>

                <td>Graph</td>
            </tr>

            <tr class="include">
                <td><button data-adtype="1" data-adspaceid="6" class="resultbutton ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" role="button"><span class="ui-button-text">Micro Bar<br>
                88x31</span></button></td>

                <td></td>

                <td>6003</td>

                <td>Bid</td>

                <td>Graph</td>
            </tr>
        </tbody>
    </table>

不应计入包含“为什么在那里打招呼”消息的tr。

Answer 1

按类名选择行并选择备用元素

var list = $(".include")
for (i=0;i<list.length-1;i++)
 {
 if (i%2 == 0){
  // do what you want
 }
}

Answer 2

如果行数有限，可以不这样做，但我不建议使用它

table .b, table .b~.b~.b, ... {background:white;}
table .b~.b, table .b~.b~.b~.b, ...{background:blue;}
