我正在使用jQuery拖曳。我给主div增加了可拖的功能。现在,在所有子元素中,它也是可拖动的。如果父文件是可拖动的,如何禁用子div中的拖动?
$(function() {
$("#draggable").draggable();
});#draggable {
width: 150px;
height: 150px;
padding: 0.5em;
border: black solid 2px;
}
.noDrag {
width: 100px;
height: 50px;
border: blue solid 2px;
}<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<div id="draggable" class="ui-widget-content">
<p>Drag me around</p>
<div class='noDrag'>No Drag</div>
</div>

要修复此问题,请使用属性,并为其提供一个选择器,以匹配要禁用拖动行为的元素,如下所示:
$(function() {
$("#draggable").draggable({
cancel: '.noDrag'
});
});#draggable {
width: 150px;
height: 150px;
padding: 0.5em;
border: black solid 2px;
}
.noDrag {
width: 100px;
height: 50px;
border: blue solid 2px;
}<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<div id="draggable" class="ui-widget-content">
<p>Drag me around</p>
<div class="noDrag">No Drag</div>
</div>

您可以像jQuery文档https://jqueryui.com/draggable/#handle中的建议那样使用cancel或disableselection()。

<p class="ui-widget-header">…but you can't drag me by this handle.</p>
