Question

我的网页中有多个div，我想用div中的第一个链接包装它们。我为此编写了一个函数，但我想这不是动态的，所有div都有相同的链接我的错？

$(document).ready(function(){
   var findAlink = $(".tab-col-2").find("a").attr("href");
   $(".tab-col-2").wrapAll('<a href="'+findAlink+'"></a>');
});

.tab-col-2{
  width:400px;
  height:330px;
  overflow:hidden;
  border:1px solid #ccc;
  float:left;
  margin:10px;
}
.tab-col-2 img{
  width:100%;
  height:170px; 
  display:block;
}
.tab-col-2 h2,.tab-col-2 p{
  text-align:center;
}

<html lang="en">

  <meta charset="UTF-8" />
  <title>Document</title>

<div class="tab-col-2">

Answer 1

迭代div并使用现有的a标记包装元素，首先解开img。

$(document).ready(function() {
  // iterate over the divs
  $(".tab-col-2").each(function() {
    // get the `a` tag within the div
    var $a = $('a', this);
    // unwrap the img tag
    $('img', $a).unwrap();  
    // get all child nodes and wrap it with the cached `a` tag
    $(this).contents().wrapAll($a)
  });
});

＆＃13;

$(document).ready(function() {
  $(".tab-col-2").each(function() {
    var $a = $(this).find('a')
    $('img', $a).unwrap();
    $(this).contents().wrapAll($a)
  });
});

＆＃13;

.tab-col-2 {
  width: 400px;
  height: 330px;
  overflow: hidden;
  border: 1px solid #ccc;
  float: left;
  margin: 10px;
}
.tab-col-2 img {
  width: 100%;
  height: 170px;
  display: block;
}
.tab-col-2 h2,
.tab-col-2 p {
  text-align: center;
}

Answer 2

您需要循环遍历每个div，然后将其包装在标记

中

试试这个

$(document).ready(function(){
 
  $(".tab-col-2").each(function(){
    var findAlink = $(this).find("a").attr("href");
    $(this).wrapAll('<a href="'+findAlink+'"></a>');
  });
});

.tab-col-2{
  width:400px;
  height:330px;
  overflow:hidden;
  border:1px solid #ccc;
  float:left;
  margin:10px;
}
.tab-col-2 img{
  width:100%;
  height:170px; 
  display:block;
}
.tab-col-2 h2,.tab-col-2 p{
  text-align:center;
}

<html lang="en">
<head>
  <meta charset="UTF-8" />
  <title>Document</title>
</head>
<body>


<div class="tab-col-2">
<a href="http://www.stackoverflow.com">
 <img src="http://support.yumpu.com/en/wp-content/themes/qaengine/img/default-thumbnail.jpg">
</a>
<h2>Title of the box</h2>
<p>explain of the title</p>
<p>73,40 US </p>
  <a href="#">my boxes..</a>
</div><!-- col-->
