我有几个有阴影的盒子。我希望阴影在悬停时发出脉冲。下面的代码可以工作,但是当我将其中任何一个悬停时,显然会使所有阴影产生脉动。我曾尝试在setInterval函数中使用this
,以便仅在单个框中应用脉冲效果 - 但这会将代码全部破坏。我该怎么办?
$( ".pulse_label_shadow" ).hover(function() {
setInterval(function() {
$( '.pulse_label_shadow' ).toggleClass("pulse_label_shadow_hover");
}, 450);
}
);
或者更好和/或更简单,如何在使用时添加setInterval:
$( ".pulse_label_shadow" ).hover(function() {
$( this ).toggleClass("pulse_label_shadow_hover");
}, function() {
$( this ).removeClass( "pulse_label_shadow_hover" );
}
);
css看起来像这样,如果这有任何区别:
.pulse_label_shadow{
-webkit-box-shadow: 0px 0px 35px 1px rgba(255,255,255,0.5);
-moz-box-shadow: 0px 0px 35px 1px rgba(255,255,255,0.5);
box-shadow: 0px 0px 35px 1px rgba(255,255,255,0.5);
transition: all 0.8s ease;
}
.pulse_label_shadow_hover{
-webkit-box-shadow: 0px 0px 95px 1px rgba(0,255,255,0.5);
-moz-box-shadow: 0px 0px 95px 1px rgba(0,255,255,0.5);
box-shadow: 0px 0px 95px 1px rgba(0,255,255,0.5);
}
HTML(其中一个方框):
<div name="NameOfDiv">
<a class="p1 scale1_toggle scale1_toggle_hide taphover ios_auto_playback floating show_text_on_enter1" rel="nofollow" aria-haspopup="false">
<div class="indicator_up"><img src="images/indicators/up.png"/></div>
<div class="pulse_label pulse_label_shadow border_up">
<span class="ending_arrows">Title</span>
</div>
</a>
</div>

$( ".pulse_label_shadow" ).hover(function() {
$( this ).addClass("pulse_label_shadow_hover");
}, function() {
$( this ).removeClass( "pulse_label_shadow_hover" );
}
);
所以这应该按照描述添加和删除类,我认为你的问题是'脉冲',你需要重复运行过渡。为此,我们应该使用动画和'animation-iteration-count:infinite'。
@keyframes pulse {
0% {
box-shadow: 0px 0px 35px 1px rgba(255,255,255,0.5);
}
100% {
box-shadow: 0px 0px 95px 1px rgba(255, 0, 0 ,0.5);
}
}
.pulse_label_shadow_hover{
animation: pulse 5s infinite;
}
没有jQuery来执行悬停http://codepen.io/mrbizle/pen/QjEMeO

,而不是为每个.pulse_label_shadow
绑定hover
回调。尝试使用jQuery each

使用clearInterval()
设置间隔并将其清除。
var interval;
$(".pulse_label_shadow").hover(function(event) {
console.log('bsaang');
interval = setInterval(function() {
$(event.target).closest(".pulse_label_shadow").toggleClass("pulse_label_shadow_hover");
}, 450);
}, function(event) {
clearInterval(interval);
$(event.target).closest(".pulse_label_shadow").removeClass("pulse_label_shadow_hover");
});
.pulse_label_shadow{
-webkit-box-shadow: 0px 0px 35px 1px rgba(255,255,255,0.5);
-moz-box-shadow: 0px 0px 35px 1px rgba(255,255,255,0.5);
box-shadow: 0px 0px 35px 1px rgba(255,255,255,0.5);
transition: all 0.8s ease;
}
.pulse_label_shadow_hover{
-webkit-box-shadow: 0px 0px 95px 1px rgba(255, 0, 0, 0.5);
-moz-box-shadow: 0px 0px 95px 1px rgba(255, 0, 0, 0.5);
box-shadow: 0px 0px 95px 1px rgba(255, 0, 0 ,0.5);
