如何使用 jquery sortable 对一组元素进行排序并防止放置点

Question

我有一个类别列表，每个类别下面都有自己的问题。我想根据他们的问题对所有类别进行排序。

使用我当前的代码，我只能对类别栏进行排序，但问题仍然存在。

这是我的 html（问题和类别可以是任意数量，因为在创建它们时可以动态添加它们）：

<span id="sortablecats" class="ui-sortable">
   <label class="categorytitle ui-sortable-handle" style="">jjjj</label>
   <div class="row ui-sortable-handle" id="questionrow">
      <div class="col-md-8">
         <p class="questionclass">hhhh</p>
      </div>
      <div class="col-md-4">
         <div class="container text-right">
            <input type="radio" name="questionlist[jjjj][hhhh]" id="radio-1" value="ok" required="">
            <label class="radiotoggle" for="radio-1"><span class="radio">Ok</span></label>
            <input type="radio" name="questionlist[jjjj][hhhh]" id="radio-2" value="fout" checked="">
            <label class="radiotoggle" for="radio-2"><span class="radio">Fout</span></label>
            <input type="radio" name="questionlist[jjjj][hhhh]" id="radio-3" value="nvt">
            <label class="radiotoggle" for="radio-3"><span class="radio">N.v.t</span></label>
         </div>
      </div>
      <div class="col-md-8">
         <p class="questionclass">jjj</p>
      </div>
      <div class="col-md-4">
         <div class="container text-right">
            <input type="radio" name="questionlist[jjjj][jjj]" id="radio-4" value="ok" required="" checked="">
            <label class="radiotoggle" for="radio-4"><span class="radio">Ok</span></label>
            <input type="radio" name="questionlist[jjjj][jjj]" id="radio-5" value="fout">
            <label class="radiotoggle" for="radio-5"><span class="radio">Fout</span></label>
            <input type="radio" name="questionlist[jjjj][jjj]" id="radio-6" value="nvt">
            <label class="radiotoggle" for="radio-6"><span class="radio">N.v.t</span></label>
         </div>
      </div>
   </div>
   <label class="categorytitle ui-sortable-handle" style="">Testt</label>
   <div class="row ui-sortable-handle" id="questionrow">
      <div class="col-md-8">
         <p class="questionclass">test</p>
      </div>
      <div class="col-md-4">
         <div class="container text-right">
            <input type="radio" name="questionlist[Testt][test]" id="radio-7" value="ok" required="">
            <label class="radiotoggle" for="radio-7"><span class="radio">Ok</span></label>
            <input type="radio" name="questionlist[Testt][test]" id="radio-8" value="fout" checked="">
            <label class="radiotoggle" for="radio-8"><span class="radio">Fout</span></label>
            <input type="radio" name="questionlist[Testt][test]" id="radio-9" value="nvt">
            <label class="radiotoggle" for="radio-9"><span class="radio">N.v.t</span></label>
         </div>
      </div>
   </div>
</span>

还有我的js：

$( "#sortablecats" ).sortable({
    placeholder: "ui-state-highlight",
    connectWith: "#questionrow",
    cancel: "#questionrow"
  });

我有一个 jsfiddle 来演示当前发生的事情

我怎样才能只对包含所有问题的类别进行排序？并且只能将它们排序在其他组的上方或下方（因此不是在另一个组中间的组）？

Answer 1

您需要将所有可排序的内容放在同一个子项中 div 并将它们 link 放在父项中。

例如让父 div 像这样：

<div id="sortMyContents">
    <div>Content to be draggable with everything inside</div>
    <div>Content to be draggable with everything inside</div>
</div>

按照这个逻辑，您的代码应该是：

$("#sortablecats").sortable({
  connectWith: "#questionrow",
  cancel: "#questionrow"
});
