ionic3 集成 devextreme 图表

devextreme在国内相对来说用得比较少，但在国外却很火。而且功能很强大，可以说基本的网页需要的UI它都提供有，还能兼容PC和手机H5。

1. 集成到ionic

1.1 在项目根目录执行安装

$ npm install --save devextreme devextreme-angular

1.2 在项目根目录创建copy.config.js文件

填入

var copy = require('@ionic/app-scripts/config/copy.config.js');

copy.copyStyleSheets = {
  src: ['{{ROOT}}/node_modules/devextreme/dist/css/**/*'],
  dest: '{{WWW}}/assets/css'
};

module.exports = copy;

1.3 修改package.json文件

"config" : {
    "ionic_copy": "./copy.config.js"
},

1.4 index.html引入css样式

css来自于npm 下载的包，复制一份到

最后在src文件夹的index.html里引入

2. 调用

2.1 app.module.ts文件中将所需的独立模块（或整个DevExtreme）导入到此

import { DxDataGridModule } from 'devextreme-angular';

@NgModule({ 
    ... 
    imports: [ 
        ... 
        DxDataGridModule , 
        ... 
    ] 
})

如果你的页面使用了懒加载，那么就应该导入该页面的Module里，例如：

2.2 使用

html代码

ts代码

import { Customer, Service } from './app.service';

 customers: Customer[];

 constructor(service: Service) {
        this.customers =  service.getCustomers();
 }

模拟数据

import { Injectable } from '@angular/core';

export class Customer {
    ID: number;
    CompanyName: string;
    Address: string;
    City: string;
    State: string;
    Zipcode: number;
    Phone: string;
    Fax: string;
    Website: string;
}

let customers: Customer[] = [{
