jQuery选择器

Question

I have the following HTML Table: 我有以下HTML表：

<table class="display" style="width: 1000px;" id="failoverServers">
    <thead>
        <tr>
            <th class="row_selector_head"> <input type='checkbox' class='select_all_chkbx'/></th>
            <th><div>{% trans "IP ADDRESS" %}</div></th>
            <th><div>{% trans "VIRTUAL IP ADDRESS" %}</div></th>
            <th><div>{% trans "USERNAME" %}</div></th>
            <th><div></div></th>
        </tr>
    </thead>

    <tbody>
    {% for i in list %}
        <tr rel="{{ i.id }}">
            <td class="row_selector"><input type='checkbox'/></td>
            <td rel="ip">{{ i.ipAddress }}</td>
            <td rel="virtualIP">{{ i.virtualIpAddress }}</td>
            <td rel="username">{{ i.username }}</td>

        </tr>
    {% endfor %}

    </tbody>
</table>

If I do the following: 如果我执行以下操作：

var list = "";
            $('#failoverServers td.row_selector.selected').each(function() {
            var row = $(this).closest('tr');
            var id = row.attr('rel');
            list += id + " ";           
        });

Then I have a list of the numbers in the very first checkbox column. 然后在第一个复选框列中有一个数字列表。

I want to get a list of the following from the table: 我想从表中获取以下列表：

<td rel="ip">{{ i.ipAddress }}</td>

What jquery selector do I use for this?? 我为此使用什么jquery选择器？

Thanks 谢谢

Answer 1

Try this: 尝试这个：

var list = [];

$('#failoverServers td.row_selector.selected').each(function() {
    var row = $(this).closest('tr');
    list.push($(row).children("td[rel=ip]")[0].text());
});

Thanks for all the comments. 感谢所有的评论。 I have got the following working: 我有以下工作：

 var list = [];
  $('#failoverServers td.row_selector.selected').each(function() {
        var row = $(this).closest('tr');
        var serverIp = row.find('td[rel=ip]').text();
        list += serverIp + " ";         
    });

What I want to do is to just get all the ip items from the table whether they are selected or now (Just get all them) How do I do this? 我想做的就是从表中获取所有ip项目，无论它们是已选择还是现在（仅获取全部）。我该怎么做？

Here is your working example (static so that I could test). 这是您的工作示例（静态，以便我可以测试）。 Place your template placeholders accordingly and change your markup (if you want to be standarts complient): your table header contains 5 cells, but td's in the rows are just 4, divs should not be placed in td s - my IDE is screaming :) and these 'rel's - why do you use them - rels should be used in links. 相应地放置模板占位符并更改标记（如果您希望符合标准格式）：表头包含5个单元格，但行中的td仅4个，div不应放置在td s中-我的IDE尖叫:)这些“ rel”（为什么要使用它们）“ rels”应在链接中使用。 I think "id" and "class" are sufficient to achieve everything you need ("id's" for unique elements, "class" for as many as you want). 我认为“ id”和“ class”足以满足您所需的一切（“ id”代表唯一的元素，“ class”代表您想要的任何数量）。

And result is: 结果是： jQuery选择td数据检索结果
