从第三方库扩展 vue.js 组件 [英] Extend vue.js component from third-party library

问题描述

我正在使用 element-ui 中的组件 ElDatepicker，我想更改它的模板和事件处理程序方法.我正在尝试在单个文件组件中做这样的事情:

I'm using component ElDatepicker from element-ui and I want to change it's template and event handler method. I'm trying to do something like this in single file component:

import Vue from 'vue';
import ElDatePicker from 'element-datepicker'
Vue.use(ElDatePicker)
var dpkr = Vue.component('ElDatePicker')
console.log(dpkr)
export default {
    extends: ['ElDatePicker']
}

但它不起作用.怎么改?

But it doesn't work. How i can change it?

推荐答案

您的主要问题是 extends 应该指定单个组件而不是数组.您应该引用组件而不是名称.

Your main problem is that extends should specify a single component and not an array. You should reference the component and not the name.

import Vue from 'vue';
import ElDatePicker from 'element-datepicker'

export default {
  extends: ElDatePicker
}

您发布的 repo 来自 element-ui

The repo you posted is from element-ui

做npm install element-ui

那么:

import { DatePicker } from 'element-ui'
export default {
  // Use mixins for array syntax
  mixins: [DatePicker]
  // OR use extends without array
  extends: DatePicker
}
