此文接vue生命周期学习心得（上）http://www.cnblogs.com/pengshadouble/p/7488330.html
通过vue生命周期学习心得（上），大至了解了vue生命周期的８个阶段及相关钩子函数触发的时间点，这章我们通过简单的代码看一下具体的运行结果：

<template>
  <div id="container">
    <headers></headers>
    <router-view></router-view>
    <!--<hello></hello>-->
  </div>
</template>

<script>
  import Hello from ‘./components/Hello‘
  export default {
   data() {
     return {
       message: ‘vue的生命周期！‘
     }
   },
    beforeCreate: function () {
      console.log(‘%c创建前(beforeCreate)...... ‘, ‘color: red‘);
      console.log(‘data: ‘+ this.message);
      console.log(‘el: ‘+ this.$el);
      this.init()
    },
    created: function () {
      console.log(‘%c创建后(created)......‘, ‘color: red‘);
      console.log(‘data: ‘+ this.message);
      console.log(‘el: ‘+ this.$el);
      this.init()
    },
    beforeMount: function () {
      console.log(‘%c挂载前(beforeMount)......‘, ‘color: red‘);
      console.log(‘data: ‘+ this.message);
      console.log(‘el: ‘+ this.$el);
    },
    mounted: function () {
      console.log(‘%c挂载后(mounted)......‘, ‘color: red‘);
      console.log(‘data: ‘+ this.message);
      console.log(‘el: ‘+ this.$el);
    },
    beforeUpdate: function () {
      console.log(‘%c更新前(beforeUpdate)......‘+ new Date(), ‘color: red‘);
      console.log(‘data: ‘+ this.message);
      console.log(‘el: ‘+ this.$el);
    },
    updated: function () {
      console.log(‘%c更新后(updated)......‘+ new Date(), ‘color: red‘);
      console.log(‘data: ‘+ this.message);
      console.log(‘el: ‘+ this.$el);
    },
    beforeDestroy: function () {
      console.log(‘%c销毁前(beforeDestroy)......‘, ‘color: red‘);
      console.log(‘data: ‘+ this.message);
      console.log(‘el: ‘+ this.$el);
    },
    destroyed: function () {
      console.log(‘%c销毁完成后(destroyed)......‘, ‘color: red‘);
      console.log(‘data: ‘+ this.message);
      console.log(‘el: ‘+ this.$el);
    },
    methods:{
      init() {
        console.log(‘%c事件初使化成功(methods)......‘, ‘color: blue‘)
      }
    }
  }
</script>

<style>
#app {
  font-family: ‘Avenir‘, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>
