jquery - 当使用 .html 获取 jQuery 内容时，该内容会丢失 jQuery 功能。

Question

<div id="mainContent">
<div class="photoShow"></div>
<div class="photo_nav"></div>
<div class="photo_caption">
<div class="photo_caption_content"></div>
</div>

// .photo_content has jQuery content and photo background
<div id="content">
<div class="photo_content"></div>
<div class="photo_content"></div>
<div class="photo_content"></div>
</div>

  <script>
  $('.photo_nav a.photo_nav_item').click(function(){
var navClicked = $(this).index();
var Photo = $('.photo_content').get(navClicked);
var curPhoto = $(Photo).html();
  $(".photo_nav a.photo_nav_item").removeClass('current');
  $(".photoShow").removeClass('current');
$(this).addClass('selected');
$(".photoShow").fadeIn('slow', 'swing');
$(".photoShow").html(curPhoto);
   });
  </script>

  // .photo_content has jQuery properties which runs fine by itself. But with this click      //function, it loses the properties. Using .get, instead of .html i.e. 


 $(".photoShow").get(Photo); 

 //keeps the contents working but then I lose navigation index property.
 //in conclusion, with .html, it displays correct .photo_content but DOM does not work.
 //With .get, I get .photo_content that works but indexing does not work.

Answer 1

这个问题不是 100% 清楚。但是 .get() 和 .html() 返回根本不同的东西。

.get() 返回一个 DOM 元素

.html() 返回(或设置)一个 HTML 内容字符串。

另请注意，这没有意义:

$(".photoShow").get(Photo);

除非 Photo 是一个整数，根据您的代码，它不是一个整数。

这有帮助吗？如果不是 - 您发布的代码中的哪一行没有达到您的预期？
