一、
代码如下：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> <script src="https://unpkg.com/vue/dist/vue.js"></script> </head> <body> <div id="app"> {{data}} </div> <script> var app = new Vue({ el: "#app", data: { data: "这是测试", info: "none" }, beforeCreate() { console.log("创建前======="); console.log(this.data); console.log(this.$el); console.log("这是一条分割线=========="); }, created() { console.log("已创建========="); console.log(this.data); console.log(this.$el); console.log("这是一条分割线=========="); }, beforeMount() { console.log("mount之前=========="); console.log(this.info); console.log(this.$el); console.log("这是一条分割线=========="); }, mounted() { console.log("mounted======"); console.log(this.info); console.log(this.$el); console.log("这是一条分割线=========="); }, beforeUpdate() { console.log("更新前========="); console.log("这是一条分割线=========="); }, updated() { console.log("更新完成======="); console.log("这是一条分割线=========="); }, beforeDestroy() { console.log("销毁前========"); console.log(this.info); console.log(this.$el); console.log("这是一条分割线=========="); }, destroyed() { console.log("已销毁========="); console.log(this.info); console.log(this.$el); console.log("这是一条分割线=========="); }, }) </script> </body> </html>
循环渲染
<div id="myData"> {{userModel.type}} <template v-for="value in userModel.data"> <template v-if="userModel.type=='No_House_Holder'"> 输出值{{value["ctime"]}} </template> <template v-else-if="userModel.type=='House_Holder'">输出值{{value["ctime"]}}</template> <template v-else>输出值{{value["ctime"]}}</template> </template> </div>
