                            #### vue中watch的簡單用法

1.監聽值的變化：
~~~
// 在data里定義初始值
data: {
	a: 1,
    b: 2,
    form: { userName: '', password: ''}
},
// watch監聽值單個的變化
watch: {
	a: function(val, oldval) {
    	console.log('new: %s, old: %s', val, oldVal)
    },
    //檢測一個對象的值的變化
    form: {
    	handler: function(val, oldval){
        	console.log('new: %s, old: %s', val, oldVal)
        },
	//確認是否深入監聽      
        deep: true;
	}
}
~~~

2.監聽路由參數的變化：
~~~
// 定義方法
methods: {
	getRoute(code, state){}
},
// 在created里調用
created() {
	this.getVal(code, state);
}
// 在watch監聽路由參數的變化
watch: {
	$route () {
    	if(this.$route.query.code != ""){
        	this.getVal(this.$route.query, this.$route.query)
        }
    }
}
