我正在使用 vue.js、vue-resource、vue-mdl 和 google material design lite 构建一个 Web 应用程序。JS 编译是通过 laravel elixir 使用 webpack 进行的。在这个应用程序中，我必须为从 Rest API（Django Rest Framework）返回的数组中的每个对象呈现一个表格行。我在 html 中编写了以下代码来使用 vue.js 呈现内容：

<tr v-for="customer in customers">
    <td class="mdl-data-table__cell--non-numeric">{{ customer.status }}</td>
    <td class="mdl-data-table__cell--non-numeric">{{ customer.name }}</td>
    <td class="mdl-data-table__cell--non-numeric">{{ customer.company }}</td>
<tr>

这应该将数组中的所有对象呈现为表格行。我还尝试将上述内容包装在这样的模板标签中：

<template v-for="customer in customers">
<tr>
    <td class="mdl-data-table__cell--non-numeric">{{ customer.status }}</td>
    <td class="mdl-data-table__cell--non-numeric">{{ customer.name }}</td>
    <td class="mdl-data-table__cell--non-numeric">{{ customer.company }}</td>
</tr>
</template>

这也没有改变。我还尝试在 vue 实例的 ready() 函数中对数组进行硬编码，但这也无济于事。

window._ = require('lodash');
require('material-design-lite');
window.Vue = require('vue');
require('vue-resource');
var VueMdl = require('vue-mdl');
Vue.use(VueMdl.default);
const app = new Vue({
    el:'body',
    ready: function(){
        //this.getCustomerList();
        this.customers = [
            { name: "Peter", status: "true", company: "Company 1"},
            { name: "John", status: "false", company: "Company 2"}
        ]

    },
    data: {
        customers: [],
        response: null,
        messages: []
    },
    methods: {
        getCustomerList: function()
        {
            this.$http({url: '/api/customers/', method: 'GET'}).then(function(response){
                //Success
                this.customers = response.data
                console.log(response.data)
            },
            function(response){
                console.log(response)
            })
        }
    }
})

将上述更改为此也不会改变：

window._ = require('lodash');
require('material-design-lite');
window.Vue = require('vue');
require('vue-resource');
var VueMdl = require('vue-mdl');
Vue.use(VueMdl.default);
const app = new Vue({
    el:'body',
    ready: function(){
        //this.getCustomerList();

    },
    data: {
        customers: [
            { name: "Peter", status: "true", company: "Company 1"},
            { name: "John", status: "false", company: "Company 2"}
        ],
        response: null,
        messages: []
    },
    methods: {
        getCustomerList: function()
        {
            this.$http({url: '/api/customers/', method: 'GET'}).then(function(response){
                //Success
                this.customers = response.data
                console.log(response.data)
            },
            function(response){
                console.log(response)
            })
        }
    }
})

我还尝试制作一个没有应用任何 Google MDL 类的普通 html 表，这也没有给出任何结果。登录this.customers到控制台显示它确实包含数据，但由于某种原因它没有呈现。这是为什么？我究竟做错了什么？

这是您的代码片段，可以按预期工作。我已经在 CDN 中添加了对您提到的库的引用，但我没有对它们做任何事情。我将此作为起点，让您看看是否可以在这里找到哪些更改会重现您的问题。

const app = new Vue({
  el: 'body',
  ready: function() {
    //this.getCustomerList();
    this.customers = [{
      name: "Peter",
      status: "true",
      company: "Company 1"
    }, {
      name: "John",
      status: "false",
      company: "Company 2"
    }]
  },
  data: {
    customers: [],
    response: null,
    messages: []
  }
})

它现在似乎正在工作。在里面app.js我有：

const app = new Vue({ el: 'body' })

出于某种原因，这与我在里面创建的那个相冲突customer_list.js——尽管我的方法工作得很好。
