vuejs制作背景淡入淡出切換動(dòng)畫的實(shí)例

1、vuejs制作背景淡入淡出切換動(dòng)畫的實(shí)例安裝好vuejs之后，在至添加s代碼如下empltedivlassounddivlassnsitiov:cssfalsevefore-enter=beforeEnterventerenterveave=eavev-bid:src=showImgvsitivdivlassscreenvtematesexdefaulamegroundeturmgs:sAniate:lse,sstbg/0.jpgsdex:strueounted:fuhis.nextck(funhis.slse;his.eths:functionvhisthis;hisget(sts.imgs

6、-resource用法用來獲取圖片的json數(shù)據(jù)this.$http.get(url).then(response=console.log(response.body);,response=console.log(response.body););用vue-resource時(shí)需要把importVueResourcefromvue-resourceVue.use(VueResource);寫到main.js中去mounted函數(shù)中，需要將運(yùn)行函數(shù)放在this.$nextTick(function()中在vue中用velocity-animatenpminstallvelocity-animate

7、-save-dev在main.js中加入importVelocityfromvelocity-animate多圖片循環(huán)過度效果這里研究了很久，頁(yè)面進(jìn)去之后會(huì)直接從eave函數(shù)開始運(yùn)行，不是想象的從beforeEnter開始。后來終于弄清楚為什么了，把show:true改成show:false，則可以讓頁(yè)面從beforeEnter前開始。exportdefaultname:background,data()returnimgs:,isAnimate:false,showImg:static/bg/0.jpg,showIndex:0,show:true,mounted:function()this

8、.$nextTick(function()this.show=false;this.bg_data(););,methods:bg_data:function()var_this=this;this.$http.get(static/data/bg.json).then(function(response)_this.imgs=response.body;);,beforeEnter:function(name)name.style.opacity=0;name.style.transform=scale(1)rotate(0deg);,enter:function(name,done)varvm=this;Velocity(name,opacity:1,scale:1.2,rotateZ:3deg,duration:6000,complete:function()done();vm.show=false;);,leave:function(name,done)varvm=this;Velocity(name,opacity:0,scale:1,rotateZ:0deg,duration:6000,complete:function()done()vm.showIm
