<script type="text/javascript">

	var event = new Vue()

	Vue.component('jony',{
		template:"<div>jony说<input @keyup='saidsome' type='text' v-model='jony_said'>{{jony_said}}</div>",
		data:function(){
			return {
				jony_said:'',
			}
		},
		methods:{
			saidsome:function(){
				event.$emit('said_something',this.jony_said)
			}
		}
	})
	Vue.component('tom',{
		template:"<div>tom听：{{tom_said}}",
		data:function(){
			return {
				tom_said:'',
			}
		},
		mounted:function(){
			var that = this
			event.$on('said_something',function(data){
				that.tom_said = data
			})
		},
	})
	new Vue({
		el:'#one',
	})
</script>

这里有个知识点非常重要：是mounted是监听的意思

var event = new Vue()是中间事件调度器  主要用于同级组件间是的数据通信
