集成仪表板设计器

功能概述

Wyn 支持把仪表板设计器嵌入到 Web 应用程序的 DIV 容器中去,为最终的用户提供在线直接设计仪表板的能力。

本文为您介绍具体的集成方法。

操作介绍

1. 安装最新的集成包。

https://www.npmjs.com/package/@grapecity-software/wyn-integration

npm install @grapecity-software/wyn-integration

2. 集成。

将仪表板设计器添加到 DIV容器 “wyn-root”中:

import { WynIntegration } from "@grapecity-software/wyn-integration";

let designer:any = null;
const createViewer = (baseURL, token, dashboardId) => {
    if (designer){
        designer.destroy();
    }
    
    WynIntegration.createDashboardDesigner({
        baseUrl: baseURL, //'http://example.com:51980',
        token: token,
        defaults: {
            dashboardId: dashboardId,
        },
        features: {
        }
    }, '#wyn-root').then(instance => {
        designer = instance;
    });
}

参数说明:

  • baseURL 指的是 Wyn 服务器的地址。

  • token 指的是访问 Wyn 服务器的令牌,在 Wyn 的后台管理生成,token 所代表的用户需要具有创建仪表板的权限。具体获取方法,请详见生成令牌

  • defaults 用来配置高级查看器的默认配置项,详细的项目请参见:DashboardDesignerDefaults

    例如通过 defaults 指定默认数据集。

defaults: {
     datasetId: datasetId
},

datasetId 可以从 Wyn 的文档列表获取。

如此,在集成之后的设计器中,添加组件时则会自动加载数据集。

image

通过 defaults 对象的 dashboardId 指的是仪表板文档 Id,可以从 Wyn 的文档列表获取。如果 dashboardId 为空,设计器会创建一个空的文档。

image

  • features 用来配置高级查看器的功能配置项,详细的项目参见:dashboarddesignerfeatures

  • “wyn-root” 指的是嵌入到 HTML DIV 容器的 Id。

  • createDashboardDesigner 异步 then 方法返回的 instance 对象,是创建完成的 Designer 实例对象,实例对象的接口参见文档:dashboard.DashboardDesigner

  • 通过设计器接口,用户可以挂接事件,添加可视化组件等等,示例代码:

    // 通过组件模板添加组件
    designer.addVisualByTemplateId(componentTemplateId, left, top);
    
    // 添加嵌入式仪表板
    designer.addVisual("embeddedDashboard", width, height, left, top, { documentId });
    
    // 添加嵌入式报表
    designer.addVisual("embeddedReport", width, height, left, top, { doumentcId });

更多的示例参见 Wyn 嵌入式分析体验 (https://wyn.grapecity.com.cn/playground/index.html)
