onCreate: function() { this.setView("leftMenu.html", { items : [] }); me.threeTrigger = iAuto.Util.bind(me,me.threeTrigger); }, ... ... releaseBtn : function(event){ var me = this; setTimeout(me.threeTrigger(event),700); }, threeTrigger : function(event){ var me = this,$el = me.$element; return function() { me.returnTrigger(event); } }, returnTrigger : function(event){ var me = this,$el = me.$element; var klass = $(event.target).data("klass"); $el.find("."+klass).removeClass("pressed"); $el.trigger(klass); },
用setTimeout做延时会丢失上下文，所以首先绑了this，
然后这家伙还不能带参数，那么需要再写个函数，该函数返回一个不带参数的函数，详细转自

动画方面我采用的时给after加上帧动画：
.left_menu .bigSize:after { content: ""; position: absolute; top: 8px; left: 40px; width: 45px; height: 45px; display: block; z-index: -1; border-radius: 45px; opacity: 0; background-color: #373737; } .left_menu .bigSize:hover:after { -webkit-animation: boom 0.7s ease; } @-webkit-keyframes boom { 0% { opacity: 0; } 5% { -webkit-transform: scale(1.2); opacity: 0.5; } 70% { -webkit-transform: scale(1.6); opacity: 0.8; } 100% { -webkit-transform: scale(2.4); opacity: 1; width: 353px; height: 66px; display: block; } }
动画的质感需要理科基础，有空深入研究。
