jquery - 查询从多个类中选择单个类

Question

我非常需要帮助 我有一张 table ，我需要从该行获取两个跨度标签 已选中复选框并将其设为变量

这是表格，我需要的类是 .down payment 和 .fullpay 但仅限于选中的行

如果有帮助，这里是该表格的屏幕截图，以帮助理解

<table class="table">
<tr class="planbreak">
    <td rowspan="2"> <input type="checkbox" name="plan"> </td>
    <td colspan="3" class="plan-title">Premium Add - Stated</td>
    <td colspan="2" class="plan-right"><span class="badge"><a href="#" data-toggle="modal" data-target="#modifiyvehicle">T &amp; C</a></span> 60/125000</td>
</tr>
<tr class="plan-info">
    <td>10% Down: $<span class="downpayment">262.00</span></td>
    <td class="text-center">18 Months: $131.15</td>
    <td class="text-center">12 Months: $196.73</td>
    <td class="text-center">Full Pay: $<span class="fullpay">2,623.00</span></td>
    <td class="text-right">Coverage miles: 15,000 (yr)</td>
</tr>
<tr class="planbreak">
    <td rowspan="2"> <input type="checkbox" name="plan" > </td>
    <td colspan="3" class="plan-title">Premium Add - Stated</td>
    <td colspan="2" class="plan-right"><span class="badge"><a href="#" data-toggle="modal" data-target="#modifiyvehicle">T &amp; C</a></span> 60/100000</td>
</tr>
<tr class="plan-info">
    <td>10% Down: $<span class="downpayment">262.00</span></td>
    <td class="text-center">18 Months: $131.15</td>
    <td class="text-center">12 Months: $196.73</td>
    <td class="text-center">Full Pay: $<span class="fullpay">2,623.00</span></td>
    <td class="text-right">Coverage miles: 15,000 (yr)</td>
</tr>
</table>

我已经尝试过了

downpay = $(this).closest('tr').next().next('span').text();

但不起作用

downpay = $(this).closest('tr').next().find('span').text();

这只是返回所有类

Answer 1

您的第二次尝试几乎是正确的，只需将类添加到 span 选择器即可:

downpay = $(this).closest('tr').next().find('span.downpayment').text();
