Question

我有2个div，点击每个div我正在添加课程＆＃34;任务活动＆＃34;分别：一旦点击第一个div，正在添加类，然后再次点击另一个div。我正在搜索父div并删除类并添加到当前单击的元素（就像单选按钮一样）。

问题：每当我尝试检查if($(this).parent('').hasClass)时，它总会返回false。

HTML : 
<div class="full-page-width">


<div class="doctor-wrap clrfix">
            <div class="doctor-left">
                <div class="doc-img">

                <span class="doctor-txt">Tự chọn  bác sĩ yêu thích</span>
            </div>
            <div class="doctor-right">
                <div class="doc-img">

            </div>
        </div>
    </div>

        /*--- Mission Page Ends ---*/

Answer 1

问题是.parent（“。doctor-wrap”）

你必须做.parent s （“。doctor-wrap”）

但是，你可以这样做：

https://jsfiddle.net/bcnppybm/2/

$('.doc-img').click(function() {
    $('.doc-img').each(function(){$(this).removeClass('mission-active');});
    if (!$(this).hasClass('mission-active')) {
    $(this).addClass('mission-active');
  }
})

hasClass jQuery总是给出＆＃34; false＆＃34;
