javascript - Angular 2 Fusion Chart 集成

Question

我刚开始使用 Angular2。我正在尝试集成 Fusion charts与 Angular2。我已经安装了所有必要的模块( @types/fusioncharts 和 fusioncharts )。下面是fusionchart组件代码。

import { Component, OnInit } from '@angular/core';
import { Http, Response } from '@angular/http';
import * as FusionCharts from "FusionCharts";
import '../../node_modules/fusioncharts/fusioncharts.charts.js';

@Component({
    moduleId: module.id.toString(),
    templateUrl: 'fusioncharts2.component.html'
})

export class FusionChartsComponent2 {
    revenueChart: any;

    constructor() {

    }

    ngAfterViewInit() {
        this.chartConfig()
    }

    public chartConfig() {
        this.revenueChart = new FusionCharts({
            type: 'column3d',
            renderAt: 'chart-container',
            width: '500',
            height: '300',
            dataFormat: 'json',
            dataSource: {
                "chart": {
                    "caption": "Monthly revenue for last year",
                    "subCaption": "Harry's SuperMart",
                    "xAxisName": "Month",

                    "divLineGapLen": "1",
                    "canvasBgColor": "#ffffff"
                },

                "data": [
                    {

                        "value": "680000"
                    },
                    {
                        "label": "Aug",
                        "value": "620000"
                    },
                    {
                        "label": "Sep",
                        "value": "610000"
                    },
                    {
                        "label": "Oct",
                        "value": "490000"
                    },
                    {

    export class AppModule { }

执行我的代码时出现以下错误。

    vendor.js:28488 [HMR] Waiting for update signal from WDS...
    vendor.js:4073 Angular is running in the development mode. Call enableProdMode() to enable the production mode.
    app.js:27495 GET http://localhost:9966/fusioncharts.charts.js (404)
    vendor.js:28300 [WDS] Hot Module Replacement enabled.

如果我通过脚本在 index.html 中包含 fusionchart cdn，或者如果 fusionchart.js 存在于应用程序文件夹中，则该错误已修复。尽管 fusionchart.js 代码在应用程序包中，但它总是在根应用程序文件夹中查找 fusionchart.js。即使我尝试通过指向 node_modules 来导入类似这样的东西“import '../../node_modules/fusioncharts/fusioncharts.charts.js';”仍然没有效果.在 html 中通过脚本标签包含 js 是正确的方法吗？还有其他方法可以解决此错误吗？

Answer 1

我遇到了同样的问题。您可以通过更新 app.module.ts 来解决此问题

更新这部分来自

// Import FusionCharts Charts module
import Charts = require('fusioncharts/fusioncharts.charts');

至

// Import FusionCharts Charts module
import * as Charts from 'fusioncharts/fusioncharts.charts';
FusionChartsModule.fcRoot(FusionCharts, Charts);

是的，这将不起作用“import '../../node_modules/fusioncharts/fusioncharts.charts.js';”因为这不是导入 FusionCharts 的正确方法

正确用法也可以引用更新后的文档 https://www.fusioncharts.com/dev/getting-started/angular/angular/configure-your-chart-using-angular
