@before-enter,在隐藏后,点击让它显示的时候,显示之前会触发。@enter不同,是在动画执行的过程中触发。done触发完成之后就是@after-enter。这些是通过js钩子来实现,也就是js来实现的:
<!DOCTYPE html> <html> <head> <title></title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link rel="stylesheet" type="text/css" href="./animate.css"> <script src="./vue.js"></script> <!-- <script src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script> --> </head> <body> <div id="root"> //自定义class名字: <transition name="fade" @before-enter="handleBeforeEnter" @enter="handleEnter" @after-enter="handleAfterEnter" > <div v-show="show">hello</div> </transition> <button @click="handleClick">切换</button> </div> <script type="text/javascript"> var vm = new Vue({ el: "#root", data: { show: true }, methods: { handleClick: function() { this.show = !this.show }, //el指的是动画包裹的标签 handleBeforeEnter: function(el) { //console.log("handleBeforeEnter") //在标签从隐藏点击显示的时候,变成了红色 el.style.color = "red" }, //接收两个回调函数,el同上,done handleEnter: function(el, done) { //之前显示是红色,两秒后变成绿色 setTimeout(()=>{ el.style.color = "green" }, 2000) setTimeout(()=>{ //但4秒才告诉vue结束(也就是2秒后变绿,又4-2秒后变黑) done() //这个done很重要,执行完之后要告诉vue,已经执行完 }, 4000) }, handleAfterEnter: function(el) { el.style.color = "black" } } }); </script> </body> </html>
当然,除了入场动画,还有出场动画:
<!DOCTYPE html> <html> <head> <title></title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link rel="stylesheet" type="text/css" href="./animate.css"> <script src="./vue.js"></script> <!-- <script src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script> --> </head> <body> <div id="root"> //自定义class名字: <transition name="fade" @before-leave="handleBeforeLeave" @leave="handleLeave" @after-leave="handleAfterLeave" > <div v-show="show">hello</div> </transition> <button @click="handleClick">切换</button> </div> <script type="text/javascript"> var vm = new Vue({ el: "#root", data: { show: true }, methods: { handleClick: function() { this.show = !this.show }, //el指的是动画包裹的标签 handleBeforeLeave: function(el) { //console.log("handleBeforeLeave") //在标签从隐藏点击显示的时候,变成了红色 el.style.color = "red" }, //接收两个回调函数,el同上,done handleLeave: function(el, done) { //之前显示是红色,两秒后变成绿色 setTimeout(()=>{ el.style.color = "green" }, 2000) setTimeout(()=>{ //但4秒才告诉vue结束(也就是2秒后变绿,又4-2秒后变黑) done() //这个done很重要,执行完之后要告诉vue,已经执行完 }, 4000) }, handleAfterLeave: function(el) { setTimeout(()=>{ el.style.color = "black" }, 2000) } } }); </script> </body> </html>
