是否有一分子发射任何事件来检查三轮驱动器是否已经启动或结束?
完成科索沃安全局的过渡会产生相应的索马里行动。 每一不动产都受到攻击。 这使得内容编制者能够开展与完成过渡同步的行动。
为了确定过渡何时完成,为过渡阶段结束时发出的“OM”活动设置了“Java”诗歌听器功能。 这项活动是WebKit TransitionEvent的一个实例,其类型为
webkit TransitionEnd
。
box.addEventListener( webkitTransitionEnd ,
function( event ) { alert( "Finished transition!" ); }, false );
过渡时期结束后,发生了一起事件。 活动名称:
transend
,操作,o Transition End
, and in Web 页: 1
There is one type of transition event available. The
oTransitionEnd
event occurs at the completion of the transition.
<代码>过渡代码>活动在过渡完成时发生。 如果过渡工作在完成之前结束,则不会发生火灾。
<>Update>
所有现代浏览器现在都支持未预定的活动:
element.addEventListener ( transitionend , callsback, false);

我采用佩特的做法,但我现在开始采用以下做法:
$(".myClass").one( transitionend webkitTransitionEnd oTransitionEnd otransitionend MSTransitionEnd ,
function() {
//do something
});
或者,如果你使用boot,那么你就能够干 do。
$(".myClass").one($.support.transition.end,
function() {
//do something
});
这包括boot锁中的以下部分。 j)
+function ($) {
use strict ;
// CSS TRANSITION SUPPORT (Shoutout: http://www.modernizr.com/)
// ============================================================
function transitionEnd() {
var el = document.createElement( bootstrap )
var transEndEventNames = {
WebkitTransition : webkitTransitionEnd ,
MozTransition : transitionend ,
OTransition : oTransitionEnd otransitionend ,
transition : transitionend
}
for (var name in transEndEventNames) {
if (el.style[name] !== undefined) {
return { end: transEndEventNames[name] }
}
}
return false // explicit for ie8 ( ._.)
}
$(function () {
$.support.transition = transitionEnd()
})
}(jQuery);
说明中还包括一种可确保总是出现退约所需的良机。
// http://blog.alexmaccaw.com/css-transitions
$.fn.emulateTransitionEnd = function (duration) {
var called = false, $el = this
$(this).one($.support.transition.end, function () { called = true })
var callback = function () { if (!called) $($el).trigger($.support.transition.end) }
setTimeout(callback, duration)
return this
}
Be aware that sometimes this event doesn’t fire, usually in the case when properties don’t change or a paint isn’t triggered. To ensure we always get a callback, let’s set a timeout that’ll trigger the event manually.

element.addEventListener ( transitionend , callsback, false);
最新版本的“ Chrome”、“ Firefox”和“Sato”工程。 甚至IE10+。
在操作12时,如果你要使用简便的 Java本,转播工作将:
document.addEventListener("oTransitionEnd", function(){
alert("Transition Ended");
});
然而,如果你通过 j子约束,你需要使用 o。
$(document).bind("otransitionend", function(){
alert("Transition Ended");
});
如果有的话,你正在使用现代仪或boot子进行过滤。 j 您只能作一改动:
var transEndEventNames = {
WebkitTransition : webkitTransitionEnd ,
MozTransition : transitionend ,
OTransition : oTransitionEnd otransitionend ,
msTransition : MSTransitionEnd ,
transition : transitionend
},
transEndEventName = transEndEventNames[ Modernizr.prefixed( transition ) ];

就真的,不这样做!
$.fn.transitiondone = function () {
return this.each(function () {
var $this = $(this);
setTimeout(function () {
$this.trigger( transitiondone );
}, (parseFloat($this.css( transitionDelay )) + parseFloat($this.css( transitionDuration ))) * 1000);
});
};
$( div ).on( mousedown , function (e) {
$(this).addClass( bounce ).transitiondone();
});
$( div ).on( transitiondone , function () {
$(this).removeClass( bounce );
});
如果你只想发现一个单一的过渡目的,而在此不使用任何联合材料框架,则这种功能便捷:
function once = function(object,event,callback){
var handle={};
var eventNames=event.split(" ");
var cbWrapper=function(){
eventNames.forEach(function(e){
object.removeEventListener(e,cbWrapper, false );
});
callback.apply(this,arguments);
};
eventNames.forEach(function(e){
object.addEventListener(e,cbWrapper,false);
});
handle.cancel=function(){
eventNames.forEach(function(e){
object.removeEventListener(e,cbWrapper, false );
});
};
return handle;
};
使用:
var handler = once(document.querySelector( #myElement ), transitionend , function(){
//do something
});
如果你希望在某个时候取消,你仍然可以这样做。
handler.cancel();
它对其他活动使用也有好处:
