Question

点击“编辑”课后，我需要使用jquery获取特定的最接近的消息输入文本。

注意这段代码是乘以

$(".message-input").text()

对我不好..

这是代码：

<div class="1">
  <div class="2">
    <div class="3">
      <div class="3a"></div>
      <div class="3b">
        <div class="3b-inner">
        <span>aaa</span>
        <span>aaa</span>
        <p class="message-input">Get this message after click</p>
        </div>
      </div>
      <div class="3c">
      <i></i>
      <ul>
        <li class="edit">On click this button</li>
        <li class="delete"></li>
      </ul>
      </div>
    </div>
  </div>
</div>

Answer 1

这段代码说的是：

点击此.edit元素，在最近的父div之前找div查找.message-input。

＆＃13;

$(".edit").on("click",function(){
  var myText = $(this).closest("div").prev("div").find(".message-input").html();
  console.log(myText);
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="1">
  <div class="2">
    <div class="3">
      <div class="3a"></div>
      <div class="3b">
        <div class="3b-inner">
        <span>aaa</span>
        <span>aaa</span>
        <p class="message-input">Get this message after click</p>
        </div>
      </div>
      <div class="3c">
      <i></i>
      <ul>
        <li class="edit">On click this button</li>
        <li class="delete"></li>
      </ul>
      </div>
    </div>
  </div>
</div>

＆＃13;

Answer 2

假设您重复发布的结构，这是一种方式：

    $(".edit").click(function(){
        var text = $(this).closest("div.3").find(".message-input").text();
        console.log(text)
    })

示例：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="1">
  <div class="2">
    <div class="3">
      <div class="3a"></div>
      <div class="3b">
        <div class="3b-inner">
        <span>aaa</span>
        <span>aaa</span>
        <p class="message-input">Get this message after click 1</p>
        </div>
      </div>
      <div class="3c">
      <i></i>
      <ul>
        <li class="edit">On click this button</li>
        <li class="delete"></li>
      </ul>
      </div>
    </div>
  </div>

        <span>aaa</span>
        <p class="message-input">Get this message after click 2</p>
        </div>
      </div>
