我正在学习Angular 2,并尝试在Angular 2应用程序中导入nicolas kruchten的数据透视表js

当我尝试在angular 2中包装数据透视表js时,它不会给出任何错误,但是当我尝试在浏览器中检查时,它不会显示数据透视表

我可以检查组件是否已创建,但始终为空

我认为
AfterViewInit
应该让我显示表格

\\pivot.component.ts

import {Component , Inject, ElementRef, AfterViewInit} from '@angular/core';

declare var jQuery:any;
declare var $:any;
import 'pivottable/dist/pivot.min.js';
import 'pivottable/dist/pivot.min.css';
@Component({
  selector: 'app-pivot',
  template: `<div id="pivot"></div>`
})

export class PivotWrapper {

private el: ElementRef;
//constructor spelling was incorrect now working fine
constructor (@Inject(ElementRef)el: ElementRef){
    this.el = el;
}
ngAfterViewInit(){

    if (!this.el ||
        !this.el.nativeElement ||
        !this.el.nativeElement.children){
            console.log('cant build without element');
            return;
    }

    var container = this.el.nativeElement;
    var inst = jQuery(container);
    var targetElement = inst.find('#pivot');

    if (!targetElement){
        console.log('cant find the pivot element');
        return;
    }

    //this helps if you build more than once as it will wipe the dom for that element
    while (targetElement.firstChild){
        targetElement.removeChild(targetElement.firstChild);
    }

    //here is the magic
    targetElement.pivot([
            {color: "blue", shape: "circle"},
            {color: "red", shape: "triangle"}
        ],
        {
            rows: ["color"],
            cols: ["shape"]
        });
}
import { Component,ElementRef,Inject} from '@angular/core';

declare var jQuery: any;
import {PivotWrapper} from './pivot.component';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {}

这是一个使用react with pivottable(在typescipt生态系统中作为pivottable工作)的示例-可能无法回答您的问题-但可能会给您一些提示

我认为这对处理没有加载css的pivot table的人会有所帮助。 我没有意识到我忘记在
angular cli.json
中包含
pivot表css


我不知道AfterViewInit是如何使用的。我认为应该实现它并调用buildPivot(),对吗?@cmonkey这是一个愚蠢的错误,因为构造函数的拼写不正确。但是现在,当我尝试使用
pivotUI
函数时,它会给出渲染错误,而这在理论上可能会回答这个问题,在这里包括答案的基本部分,并提供链接供参考。有关如何编写更好的“基于链接”答案的说明,请参阅。谢谢我认为这里有一个输入错误,您希望在“样式”中包含“pivot.css”而不是.js文件:[“./node\u modules/pivottable/dist/pivot.min.js”,对吗?也包括在“node\u modules/jquery ui/dist/jquery ui.min.js”中,
