PHP*_*let 3 jquery fade toggle fadeout
我有一个切换淡入淡出效果但是当你多次单击该按钮时,它会不止一次地淡入和淡出.(因此,如果我快速点击淡入淡出ID 20次,它会多次淡入和淡出)如何停止此操作并使其只能在动画完成时切换淡入淡出？我尝试获取当前值并制作if语句,但它不起作用:*(
谢谢
jQuery.fn.fadeToggle = function(speed, easing, callback) {
return this.animate({opacity: 'toggle'}, speed, easing, callback);
};
$(document).ready(function() {
$('.open').click(function() {
$('#fadeMe').next().fadeToggle('slow');
});
});
您需要检查元素是否:动画,如果是,则调用.animate:
<body>
<button class="open">open</button><br>
<div id="fadeMe">fade me!</div>
<style>#fadeMe {
width:20em;
height:10em;
background:black;
color:#fff;
}</style>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
<script>
jQuery.fn.fadeToggle = function(speed, easing, callback) {
return this.animate({opacity: 'toggle'}, speed, easing, callback);
};
$(document).ready(function() {
$('.open').click(function() {
var el = $('#fadeMe').next();
if ( !el.is(':animated') ) {
$(el).fadeToggle('slow');
}
});
});
</script>
</body>
