带有图标的 jQuery 可拖动 DIV

Question

我想用 jQuery 的可拖动功能制作一些可拖动的 DIV，但这些 DIV 本身不应该是可拖动的，而只能借助每个 DIV 顶部的小图标，这样我只能在单击时移动它并将该图标拖动到 DIV 上方，而不是每次单击并拖动 div 时都进行拖动。

提前致谢

使用 handle :

$( "#draggable" ).draggable({
  handle: "p"
});

片段

$(function() {
  $( "#draggable" ).draggable({ handle: "p" });
  $( "#draggable2" ).draggable({ cancel: "p.ui-widget-header" });
  $( "div, p" ).disableSelection();
});

#draggable, #draggable2 { width: 100px; height: 100px; padding: 0.5em; float: left; margin: 0 10px 10px 0; }
#draggable p { cursor: move; }

<div id="draggable2" class="ui-widget-content">
  <p>You can drag me around&hellip;</p>
  <p class="ui-widget-header">&hellip;but you can't drag me by this handle.</p>
</div>
