如何使用Jquery/Javascript从嵌套HTML标记中获取价值 [英] How to get value from nested HTML tag with Jquery/Javascript

问题描述

我在我的网站上使用外部银行贷款计算器，该计算器在输入特定金额后会自动计算贷款条件.

I'm using an external bank-loan-calculator on my website, which after entering specific amounts of money it automatically calculates the conditions for a loan.

现在，出于显示原因，我需要从生成的值中提取一些数据.我想我可以用Jquery做到这一点，但我不确定为什么.

Now, for display reasons I need to extract some data from the generated values. I think I could do that with Jquery but I'm not sure why.

这是计算器插件生成的HTMl:

Here is the HTMl the calculator plugin generates:

<section class="info">
  <div class="graph on">
    <div class="sums">
        <dl data-type="capital">
            <dt>
                <span class="percent">2%</span>
            </dt>
            <dd>100.000</dd>
        </dl>
        <dl data-type="bankloan">
            <dt>
                <span class="percent">18%</span>
            </dt>
            <dd>400.000</dd>             
        </dl>                          
        <dl data-type="mortage">                 
            <dt>                     
                <span class="percent">80%</span>
            </dt>                 
            <dd>1.500.000</dd>             
        </dl>                  
    </div> 
 </div>
</section>

我需要的是<dd>-标记

有人建议如何实现吗?

推荐答案

是的，您可以使用jquery函数each()进行操作，该函数将解析每个<dl>元素，然后在其中的每个元素中找到<dd>元素并获取相关文本，如下所示:

Yes you can do it using jquery function each() that will parse every <dl> element, and after that find the <dd> element inside each of them and get the related text, like following :

$('.sums').find('dl').each(function(){
    $('#sums_area').append('<h2>' + $(this).find('dd').text() + '</h2>');
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<section class="info">
  <div class="graph on">
    <div class="sums">
        <dl data-type="capital">
            <dt>
                <span class="percent">2%</span>
            </dt>
            <dd>100.000</dd>
        </dl>
        <dl data-type="bankloan">
            <dt>
                <span class="percent">18%</span>
            </dt>
            <dd>400.000</dd>             
        </dl>                          
        <dl data-type="mortage">                 
            <dt>                     
                <span class="percent">80%</span>
            </dt>                 
            <dd>1.500.000</dd>             
        </dl>                  
    </div> 
 </div>
</section>
<div id='sums_area'></div>
