星評価クリックして項目を追加します.Class機能は動作しません

Question

私のjsコードに1つの問題があります。私はこのDEMOをcodepen.ioから作成しました。このデモではツリースターのdivがあることがわかります。

スターをホバーすると、.rate-btn-hoverがhovered divクラスを追加します。私もクリック機能を追加したいが、私のクリック機能コードは機能しない。誰が私を間違ってやっているの？ HTML

<div class="container"> 
    <div class="div"> 
    <div class="rate-ex1-cnt" id"ab"> 
     <div id="1" class="star star-one-1 rate-btn star-one"></div> 
     <div id="2" class="star star-one-2 rate-btn star-one"></div> 
     <div id="3" class="star star-one-3 rate-btn star-one"></div> 
     <div id="4" class="star star-one-4 rate-btn star-one"></div> 
     <div id="5" class="star star-one-5 rate-btn star-one"></div> 
    </div> 
    </div> 
    <div class="div"> 
    <div class="rate-ex2-cnt"> 
      <div id="1" class="star star-two-1 rate-btn star-two"></div> 
      <div id="2" class="star star-two-2 rate-btn star-two"></div>

      <div id="5" class="star star-two-5 rate-btn star-two"></div> 
     </div> 
    </div>

JS

var prevStars = $(this).prevAll(); 
    var nextStars = $(this).nextAll(); 

$('.star').on('mouseover',function() { 
    var prevStars = $(this).prevAll(); 
    prevStars.addClass('rate-btn-hover'); 
}); 
$('.star').on('mouseout',function(){ 
    var prevStars = $(this).prevAll(); 
    prevStars.removeClass('rate-btn-hover'); 
}); 
    // Add rate-btn-hover after click 
    $("body").on("click", ".star", function(){ 
    var prevStars = $(this).prevAll(); 
    prevStars.addClass('rate-btn-hover'); 
    }); 

Answer 1

実際にクラスが追加されていますが、ときにマウスを外に除去されます。 rate-btn-activeという別のクラスがあるので、次のようなクリックイベントで使用できます。

$('.star').on('mouseover', function() { 
 
    var prevStars = $(this).prevAll(); 
 
    prevStars.addClass('rate-btn-hover'); 
 
}); 
 
$('.star').on('mouseout', function() { 
 
    var prevStars = $(this).prevAll(); 
 
    prevStars.removeClass('rate-btn-hover'); 
 
}); 
 
// Add rate-btn-hover after click 
 
$("body").on("click", ".star", function() { 
 
    $(this).siblings().removeClass('rate-btn-active') 
 

 
    var prevStars = $(this).prevAll().addBack(); 
 
    prevStars.addClass('rate-btn-active'); 
 
});
