Vue2.0 如何动态切换组件？

Question

点击按钮切换组件 但切换不了
js:

var Rm={
    template:'#aa',
}
var Wr={
    template:'#bb',
}
var vm=new Vue({
    el:'#app',
    data:{
        currentView:Rm,
        picked:0
    },
    mounted:function(){

    },
    watch:{
        'picked':function(val){
            this.currentView=Wr
            console.log(this.currentView)
        }
    },
})

html

<script type="text/x-template" id="rm">
    <div>123</div>
<script>
<script type="text/x-template" id="wr">
    <div>456</div>
<script>
<component :is="currentView"></component>


报错内容是
vue2.0.js:2611 [Vue warn]: Cannot find element: #wr 

vue2.0.js:2611 [Vue warn]: You are using the runtime-only build of Vue where the template option is not available. Either pre-compile the templates into render functions, or use the compiler-included build.
(found in anonymous component - use the "name" option for better debugging messages.)

Answer 1

• 组件要在初始化Vue对象时或者在之前注册

• <component :is="currentView"></component>中currentView是string类型的组件名称，而不是初始化组件的options object

• 官方文档的动态组件例子很详细: https://vuejs.org/v2/guide/co...

vue-router 嵌套路由 http://router.vuejs.org/zh-cn...
