In this tutorial you will learn how to integrate Salesforce Tableau worksheets into your Angular 10 web application.

在本教程中，您将学习如何将Salesforce Tableau工作表集成到Angular 10 Web应用程序中。

Considering, you already know Angular web development, I will not walk you through how to create a Angular web app, directly dive into the recipe to cook Tableau with Angular.

考虑到您已经知道Angular Web开发，我不会逐步指导您如何创建Angular Web应用程序，直接介绍如何使用Angular编写Tableau。

Step 1:Download and add Tableau JS API Library file, into project, angular.json

步骤1：下载Tableau JS API库文件并将其添加到项目angular.json中

https://public.tableau.com/javascripts/api/tableau-2.min.js

Under the hood it actually calls to the latest version of tableau JS Library as below code

实际上，它实际上调用了Tableau JS库的最新版本，如下代码

window.tableau=window.tableau||{}.....................window.tableau._apiLoaded||(window.tableau._apiLoaded=!0,t(n("tableau-2.min.js")+"tableau-2.5.0.min.js"))}();

Our angular.json should look like below

我们的angular.json应该如下所示

"build": { ... "options": { ... "assets": [ ... ], "styles": [ ... ], "scripts": ["src/assets/libs/tableau.js"] },

Step 2: Create a component and use as below:

第2步：创建组件并按以下方式使用：

Define the tableau object to be used into angular component as below from tableau-2.min.js

定义tableau-2.min.js中要用作角组件的tableau对象，如下所示

import { Component, AfterViewInit, ViewChild, ElementRef } from '@angular/core';declare var tableau: any;// The only compatible way to access tableau object in angular 2+@Component({........

Create a function, define the worksheet url, tableau options, and create an instance of tableau Viz object, as below

创建一个函数，定义工作表URL，Tableau选项，并创建Tableau Viz对象的实例，如下所示

initViz() { const containerDiv = this.vizContainer.nativeElement; //Get the reference of DOM element that holds the tableau frame let url = "http://public.tableau.com/views/RegionalSampleWorkbook/Storms" let options = { hideTabs: true, onFirstInteractive: () => { } } this.viz = new tableau.Viz(containerDiv, url, options)}

At the end, we call the function initViz() inside lifecycle hook AfterViewInit as below

最后，我们在生命周期挂钩AfterViewInit中调用函数initViz()，如下所示

ngAfterViewInit(): void { this.initViz();}
