  • Component template should contain exactly one root element. If you are using v-if on multiple elements, use v-else-if to chain them instead.

    vue菜鸟一枚,下载github上的代码来框架和思路,添加自己新的代码调试的时候,发现了一个错误,,具体报错如:

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    12
    error  in ./src/components/page/Test.vue
     
    (Emitted value instead of an instance of Error)
      Vue template syntax error:
     
      Component template should contain exactly one root element. If you are using v-if on multiple elements, use v-else-if to chain them instead.
     
     
     @ ./src/components/page/Test.vue 5:2-167
     @ ./src/router/index.js
     @ ./src/main.js
     @ multi ./build/dev-client babel-polyfill ./src/main.js

     刚开始这样写得时候是没有发现啥错误的,我只是在后面添加一个<div></div>或是加了别的就说出现这个错误

    1
    2
    3
    <template>
        <el-button type="primary">{{test1}}</el-button>
    </template>

      原来vue模板只能有一个根对象

    所以你想要出现正常的效果,你的用一个div来或是别的标签来包裹全部的元素

    正确的写法就是:

    1
    2
    3
    4
    5
    6
    7
    8
    <template>
        <div>
            <el-button type="primary">haha1</el-button>
            <div>hahhaa</div>
            <el-input type="text" placeholder="测试一下"></el-input>
            <h1>{{test1}}</h1>
        </div>
    </template>
