how to delete specific image using jquery in sortable jquery

问题

我有一个HTML中的图像部分，其中图像以网格形式显示，用户可以拖动和重新排列，根据重新排列，图像名称存储在隐藏的输入框中，这部分代码如下：

<!-- 开始代码片段: js 隐藏: false 控制台: true Babel: false -->

<!-- 语言: lang-js -->
$(function () {
  $("#imageListId").sortable({
    update: function (event, ui) {
      getIdsOfImages();
    }, //end update
  });
});

function getIdsOfImages() {
  var values = [];
  $(".listitemClass").each(function (index) {
    values.push($(this).attr("id").replace("im", ""));
  });
  $("#outputvalues").val(values);
}

<!-- 语言: lang-css -->
/* 图像尺寸 */

.listitemClass img {
  height: 200px;
  width: 100%;
}
/* imagelistId 样式 */

#imageListId {
  margin: 0;
  padding: 0;
  list-style-type: none;
}

#imageListId div {
  margin: 0 4px 4px 4px;
  padding: 0.4em;
  display: inline-block;
}
/* 输出顺序样式 */

#outputvalues {
  margin: 0 2px 2px 2px;
  padding: 0.4em;
  padding-left: 1.5em;
  width: 250px;
  border: 2px solid dark-green;
  background: gray;
}

.listitemClass {
  border: 1px solid #006400;
  width: 25%;
}

.height {
  height: 10px;
}

  </div>
  <button type="submit" name="editcategory" class="btn btn-primary">保存</button>
</form>

<!-- 结束代码片段 -->

我想从此网格中删除某些特定图像，请告诉我如何实现这一点，提前感谢。

你需要重置可排序组件：

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->
$(function() {
  const getIdsOfImages = () => {
    const values = $('.listitemClass').map(function() {
      return this.id.replace('im', '')
    }).get();
    $('#outputvalues').val(values);
  };
  const init = () => {
    $('#imageListId').sortable({
      update: getIdsOfImages
    });
    getIdsOfImages();
  }
  $('.delete').on('click', function() {
    $(this).closest('.listitemClass').remove();
    init();
  })
  init();
});

<!-- language: lang-css -->
/* 图片尺寸 */
.listitemClass img {
  height: 200px;
  width: 100%;
}

/* imagelistId 样式 */
#imageListId {
  margin: 0;
  padding: 0;
  display:flex;
}

#imageListId div {
  margin: 0 4px 4px 4px;
  padding: 0.4em;
  display: inline-block;
}

/* 输出顺序样式 */
#outputvalues {
  margin: 0 2px 2px 2px;
  padding: 0.4em;
  padding-left: 1.5em;
  width: 250px;
  border: 2px solid dark-green;
  background: gray;
}

.listitemClass {
  border: 1px solid #006400;
  width: 25%;
}

.height {
  height: 10px;
}

<!-- language: lang-html -->

    <input id="outputvalues" type="text" value="" name="nname" />
    <input type="hidden" value="1" name="nname1" />
  </div>
</form>

<!-- end snippet -->

这是你提供的代码的翻译。如果有其他需要，请随时告诉我。

英文:

You need to reset the sortable:

$(function() {
const getIdsOfImages = () =&gt; {
const values = $(&#39;.listitemClass&#39;).map(function() {
return this.id.replace(&#39;im&#39;, &#39;&#39;)
}).get();
$(&#39;#outputvalues&#39;).val(values);
};
const init = () =&gt; {
$(&#39;#imageListId&#39;).sortable({
update: getIdsOfImages
});
getIdsOfImages();
}
$(&#39;.delete&#39;).on(&#39;click&#39;, function() {
$(this).closest(&#39;.listitemClass&#39;).remove();
init();
})
init();
});

/* image dimension */
.listitemClass img {
height: 200px;
width: 100%;
}
/* imagelistId styling */
#imageListId {
margin: 0;
padding: 0;
display:flex;
}
#imageListId div {
margin: 0 4px 4px 4px;
padding: 0.4em;
display: inline-block;
}
/* Output order styling */
#outputvalues {
margin: 0 2px 2px 2px;
padding: 0.4em;
padding-left: 1.5em;
width: 250px;
border: 2px solid dark-green;
background: gray;
}
.listitemClass {
border: 1px solid #006400;
width: 25%;
}
.height {
height: 10px;
}

&lt;script src=&quot;https://code.jquery.com/ui/1.12.1/jquery-ui.js&quot;&gt;&lt;/script&gt;
&lt;b&gt;Drag and drop images to arrange&lt;/b&gt;
&lt;div class=&quot;height&quot;&gt;&lt;/div&gt;&lt;br&gt;
&lt;div id=&quot;imageListId&quot;&gt;
&lt;div id=&quot;im1&quot; class=&quot;listitemClass&quot;&gt;
&lt;img src=&quot;https://picsum.photos/id/236/200/300&quot; alt=&quot;Image 1&quot;&gt;
&lt;button type=&quot;button&quot; class=&quot;btn btn-primary delete&quot;&gt;X&lt;/button&gt;
&lt;/div&gt;
&lt;div id=&quot;im2&quot; class=&quot;listitemClass&quot;&gt;
&lt;img src=&quot;https://picsum.photos/id/237/200/300&quot; alt=&quot;Image 2&quot;&gt;
&lt;button type=&quot;button&quot; class=&quot;btn btn-primary delete&quot;&gt;X&lt;/button&gt;
&lt;/div&gt;
&lt;div id=&quot;im3&quot; class=&quot;listitemClass&quot;&gt;
&lt;img src=&quot;https://picsum.photos/id/238/200/300&quot; alt=&quot;Image 3&quot;&gt;
&lt;button type=&quot;button&quot; class=&quot;btn btn-primary delete&quot;&gt;X&lt;/button&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;form action=&quot;&quot; method=&quot;post&quot; enctype=&quot;multipart/form-data&quot; style=&quot;margin-top:3%&quot;&gt;
&lt;div id=&quot;outputDiv&quot;&gt;
