vue.js - 在 HTML 页面中插入 VueJS 组件模板不起作用

问题描述

我有以下 main.js：

import Test from './components/Test.vue'

Vue.component('test', Test);

var vm = new Vue({
    el: '.vue-wrap',
    components: { Test },
});
window.vm = vm;

我有以下Test.vue：

<template>
    <li>
        Hello World
    </li>
</template>

<script>
    export default {
        name: 'Test',
    }
</script>

我构建应用程序并将“dist”文件夹的内容复制到我网站的“vue”文件夹中。我有以下 HTML 文件：

<!DOCTYPE html><html><head><meta charset=utf-8><link rel=apple-touch-icon sizes=76x76 href=static/img/apple-icon.png><link rel=icon type=image/png sizes=96x96 href=static/img/favicon.png><meta http-equiv=X-UA-Compatible content="IE=edge,chrome=1"><title>My App!</title><meta name=viewport content="width=device-width,initial-scale=1,maximum-scale=1,user-scalable=0"><link type=text/css href="https://fonts.googleapis.com/css?family=Muli:400,300" rel=stylesheet><link type=text/css href="https://fonts.googleapis.com/css?family=Montserrat" rel=stylesheet><link type=text/css href=https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css rel=stylesheet><link type=text/css href=https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css rel=stylesheet><link href=static/css/themify-icons.css rel=stylesheet><link href=/vue/static/css/app.d9b210b92ea60ad0856c8dc063cccfec.css rel=stylesheet></head><body><div class=wrapper id=app></div><script type=text/javascript src=/vue/static/js/manifest.bdf9878acc459aaa413c.js></script><script type=text/javascript src=/vue/static/js/vendor.0eae82ab4e0e2a32fd9c.js></script><script type=text/javascript src=/vue/static/js/app.aa1500d2bdd1b2f93122.js></script>

<div class="vue-wrap">
  <test></test>
</div>

</body>
</html>

VueJs 不应该直接用 HTML 填充“测试”标签吗？因为在我的情况下，所有 css/js 文件都加载正常，如果我在控制台中输入“vm”，我可以看到 Vue 对象，但模板部分仍然没有插入 HTML。我怎样才能做到这一点？我的页面是空的。我想加载多个组件，如果在 HTML 中找到这些组件，它们应该插入到组件槽中。

解决方案

如果您希望能够通过将其包装在“main”中来指定 Vue 正在使用的组件，则<div class="vue-wrap">可以使用slots。

var vm = new Vue({
    el: '.vue-wrap',
    template: "<slot></slot>",
    components: { 
        /* all components injected by "slots" */ 
        Test, 
        SomeComponent
    },
});

<test></test>...然后您可以通过将其添加为主 div 的子项来注入您的组件。

<div class="vue-wrap">
    <test></test>
    <some-component></some-component>
</div>

否则，如果您能够在 Vue 组件中编写模板，则应使用template@latovic 建议的键/选项。

var vm = new Vue({
    el: '.vue-wrap',
    template: `
        <test></test>
        <some-component></some-component>
    `,
    components: { Test, SomeComponent }
});

如果您正在构建应用程序，换句话说，如果您可以使用.vue文件，那么您可以在单文件组件中编写模板。

更新（由于问题更新）

在您的特定示例中，尝试删除Vue.component('test', Tree);asi 可能会由于不区分大小写的名称而导致一些问题（这样您正在创建全局组件test并且您已经导入并注册了组件Test）。

此外，如前所述，如果你想传递<test></test>给你的 HTML 而不是模板，你需要一个<slot></slot>.

import Test from "/path/to/component";

var vm = new Vue({
    el: '.vue-wrap',
    template: "<slot></slot>",
    components: { 
        /* all components injected by "slots" */ 
        Test
    },
});

但是，如果您的 index.html 完全为空，则说明您的构建过程存在问题，我们无法提供帮助，因为我们没有相关信息。
