javascript preventDefault仅在父项上 [英] javascript preventDefault only on parent item

问题描述

我正在使用javascript创建下拉导航.有孩子的任何列表项我都想阻止默认操作并执行其他操作.我已经完成了这项工作，但是当应用默认操作时，它也会应用于子列表项.

I am creating a drop down nav in javascript. Any list items that have children i would like to prevent the default action and do something else. I have this working but when applied the default action is also applied to the child list items.

这是我的HTML:

<i id="mobnavtrig" class="fa fa-align-justify fa-2x"></i>
    <div class="mobilenav">
        <li class="page_item page-item-2"><a href="/">Home</a></li>
        <li class="page_item page-item-10"><a href="?page_id=10">Who We Are</a></li>
        <li class="page_item page-item-25 page_item_has_children current_page_item parent"><a href="?page_id=25">Case Studies</a>
            <ul class='children'>
                <li class="page_item page-item-55"><a href="?page_id=55">Barratt Developments</a></li>
                <li class="page_item page-item-53"><a href="?page_id=53">Care in Bathing</a></li>
            </ul>
        </li>
        <li class="page_item page-item-27"><a href="?page_id=27">Blog</a></li>
        <li class="page_item page-item-29"><a href="?page_id=29">Get In Touch</a></li>
    </div>

这是我的JS:

$( ".mobilenav li.parent" ).click(function(event) {
        if($(this).hasClass('page_item_has_children')){
            event.preventDefault( );
            $(this).addClass('current_page_item');
            $(this).find('.children').slideToggle("fast");
        }
    });

以上是否缺少我的东西?

Is there something i am missing in the above?

推荐答案

在儿童中，您必须使用

in children click you have to use stopPropagation() to stop event bubbling

$( ".mobilenav li.parent .children" ).click(function(e){
  e.stopPropagation();

});
