vue2 关于ref

Posted 2020-10-16 ermao的博客

1，VUE2子组件索引

<div id="app">
    <navbar></navbar>
    <pagefooter></pagefooter>
</div>

Vue.component(‘navbar‘,{
    template:‘#navbar‘,
    data:function () {
        return {
            navs:[]
        }
    }
});

Vue.component(‘pagefooter‘,{
    template:‘#pagefooter‘,
    data:function () {
        return {
            footer:‘‘
        }
    }
});
new Vue({
    el:‘#app‘,
    mounted:function () {
        //ready,
        //这里怎么直接访问navbar的navs和pagefooter的footer值呢，
    }
})

2，使用ref

<div id="app">
    <navbar ref="navbar"></navbar>
    <pagefooter ref="pagefooter"></pagefooter>
</div>

new Vue({
    el:‘#app‘,
    mounted:function () {
        //ready,
        //这里怎么直接访问navbar的navs和pagefooter的footer值呢，
        console.log(this.$refs.navbar.navs);
        console.log(this.$refs.pagefooter.footer);
    }
})
