Wrap 不适用于动态加载的元素。为什么？

Question

wrap(); 本身运行良好，但在 load(); 之后调用时，它就不行了。

如何才能让它发挥作用？我试图将 wrap(); 代码放在一个单独的 .js 文件中，但这没有用。我也试过加载wrap(); inside: $( window ).on( "load", function() { ... })然后把它放在html的页脚里面，也没有解决问题。

这是我的代码：

$('.page-id-202 #partner, .page-id-201 #partner').load('https://webhelytervezo.hu/ #gallery-1');
     $(".gallery-item").each(function() {
     $(this).wrap($("<a/>").attr("href", "http://" + $(".gallery-caption", this).text().trim()));
     $("#gallery-1 a").attr('target','_blank');
});

figcaption{
display: none;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="gallery-1" class="gallery galleryid-9 gallery-columns-3 gallery-size-full"><figure class="gallery-item">
            <div class="gallery-icon landscape">
                <img width="200" height="74" src="https://webhelytervezo.hu/wp-content/uploads/2022/01/cup_revolution_logo.jpg" class="attachment-full size-full" alt="" loading="lazy" aria-describedby="gallery-1-49">

编辑 1# 和 2#：

我需要在从 https://webhelytervezo.hu/ into the #partner div of page with the .page-id-202 class (https://webhelytervezo.hu/en/) and the page with the class .page-id-201 (https://webhelytervezo.hu/en/ 加载后包装 #gallery-1 的每个 .gallery-item。该代码仅适用于主页（内容未加载但无需加载）。

编辑 3#

现在的代码是：

jQuery(document).ready(function( $ ){
$('.page-id-202 #partner, .page-id-201 #partner').load('https://webhelytervezo.hu/ #gallery-1', function(){
      $(".gallery-item").each(function() {
          $(this).wrap($("<a/>").attr("href", "http://" + $(".gallery-caption", this).text().trim()));
          $("#gallery-1 a").attr('target','_blank');
     })
});
  $(".gallery-item").each(function() {
          $(this).wrap($("<a/>").attr("href", "http://" + $(".gallery-caption", this).text().trim()));
          $("#gallery-1 a").attr('target','_blank');
     })
      });

如何简化它？

Answer 1

加载是异步函数。将您的代码放在 load 方法的回调函数中。

$('.page-id-202 #partner, .page-id-201 #partner').load('https://webhelytervezo.hu/ #gallery-1', function(){
      $(".gallery-item").each(function() {
          $(this).wrap($("<a/>").attr("href", "http://" + $(".gallery-caption", this).text().trim()));
          $("#gallery-1 a").attr('target','_blank');
     })   
})

Answer 2

您需要将它包裹在 img 标签周围，而不是它的前身：

$('.page-id-202 #partner, .page-id-201 #partner').load('https://webhelytervezo.hu/ #gallery-1');
$(".gallery-item .gallery-icon img").each(function() {
    $(this).wrap($("<a/>").attr("href", "http://" + $(".gallery-caption", this.parentNode.parentNode).text().trim()));
    $("#gallery-1 a").attr('target','_blank');
});
