在JQuery中排序后的调用事件 [英] Call event after sorting in JQuery

问题描述

在学习jQuery/jQueryUI时，我试图在对元素进行排序后调用该事件.由于jQuery有许多实现回调的方法，所以这可能相对简单.

In relearning jQuery/jQueryUI, I'm trying to call an event on an element after sorting it. This is probably relatively simple to do since jQuery has many ways to implement callbacks.

jQuery(document).ready(function($) {
  $('ul').addClass('list-unstyled');
  $('.sortable').sortable({
    revert: true,
    connectWith: ".sortable"
  });
});

ul {
  margin: .8rem 2rem !important;
}

li {
  margin: 0;
  padding: 0;
}

div>div {
  border: 1px solid #999;
  margin-bottom: 2px;
}

body {
  padding: 1rem;
}

.sortable {
  cursor: pointer;
}

.sortable>div:hover {
  background: #f0f0f0;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<div class="sortable">
  <div>
    <ul class="1">
      <li>test 1</li>
      <li>test 2</li>
    </ul>
  </div>
  <div>
    <ul class="2">
      <li>test 3</li>
      <li>test 4</li>
    </ul>
  </div>
</div>
<div class="sortable">
  <div>
    <ul class="3">
      <li>test 7</li>
      <li>test 8</li>
    </ul>
  </div>
  <div>
    <ul class="4">
      <li>test 9</li>
      <li>test 0</li>
    </ul>
  </div>
</div>

因此，假设我移动了3/4列表.我想在元素移动完成后发出回调(以更改背景或字体大小).

So let's say I move the 3/4 list. I want to issue a callback (to change the background or the font size) after the element is finished moving.

• 20101019-1145EST:我想我需要更加清楚.我正在尝试在已排序的特定元素上调用事件.我想我也许可以使用sort/change函数，但是不应该有条件吗?这不仅涉及添加类，我计划附加的最终函数将执行一些AJAX以及一些计算.

• 20101019-1145EST: I think I need to be more clear. I'm trying to call the event on a particular element that is sorted. I guess I might be able to use the sort/change function, but shouldn't there be a conditional involved? This involves more than adding a class, the eventual function I plan to attach will perform some AJAX as well as some calculations.

推荐答案

使用sortable插件的stop事件.

排序时触发此事件 已停止.

This event is triggered when sorting has stopped.

在您的示例中

$('.sortable')
    .sortable({
       revert       : true,
       connectWith  : ".sortable",
       stop         : function(event,ui){ /* do whatever here */ }
    });
