初始化Spread

此示例演示如何创建Spread.Sheets工作簿组件,还说明如何从初始化的工作簿主机DOM元素中获取组件实例。

你可以按照以下步骤创建一个SpreadJS的workbook: 在页面的head元素中添加两个 link 元素: 分别是 gc.spread.sheets.x.x.x.css 和 gc.spread.sheets.all.x.x.x.min.js. 在body元素中创建一个带有id的div元素以挂载SpreadJS组件。 在页面的onload事件中创建一个javascript变量并通过调用workbook的构造函数(需要传入上一步所创建的div元素)为其分配一个workbook对象。Workbook的构造函数还可以接收一个JSON对象,这个JSON可以设定workbook对象的一些选项,或者你可以在创建workbook之后指定这些选项。 创建对象后,你可以使用workbook对象加载SpreadJS的SSJSON文件,导入一个Excel文件,改变控件中一部分元素的可见性,比如滚动条,表单名称标签,公式编辑器,并且动态地修改工作簿上的Spread表单,表格以及图表等。其他的功能例子将展示其中的具体属性。 最后, 你可以通过使用GC.Spread.Sheets.findControl方法(需要提供工作簿所挂载的DOM元素)获取页面上的任何工作簿对象。 当然,你仍可以配合jQuery来操作SpreadJS, 例如:
import * as React from 'react'; import * as ReactDOM from 'react-dom'; import './styles.css'; import { AppFunc } from './app-func'; import { App } from './app-class'; // 1. Functional Component sample ReactDOM.render(<AppFunc />, document.getElementById('app')); // 2. Class Component sample // ReactDOM.render(<App />, document.getElementById('app'));
