javascript - 选择 Div 行以一次突出显示它

Question

[在此处输入图像描述][1]我正在创建一个检查预约，每次单击一个时，我都希望将所选行突出显示为绿色。行中的数据来自数据库。我尝试将类直接放在 div 内，但两行突出显示。

提前谢谢

这是输出

 $(document).on('click', '.selectdate', function(){


  var selected = $('#walakapake').hasClass("highlight");


$("walakapake").removeClass("row");
        if(!selected)
        {
            $('#walakapake').addClass("row highlight");
        }

  
 });

<style type="text/css">
  

#table-wrapper {
  position:relative;
}
#table-scroll {
  height:500px;
  overflow:auto;  
  margin-top:20px;
}
#table-wrapper table {
  width:100%;

}

#walakapake:hover{
background-color: #fafafa;
}

.highlight { background-color: red; }

$('.foo').click(function() {
$('.foo').removeClass('highlight'); //Removes every highlight
$(this).addClass('highlight'); //sets highlight to the clicked one
});

.highlight {
  background-color:yellow;
 }
