表单级别绑定

SpreadJS 支持绑定数据源到表单(绑定类型有表单级别绑定和单元格级别绑定。)

你可以使用 setDataSource 和 getDataSource 方法来设置获取数据源。 在设置数据源之前, 你可以使用 autoGenerateColumns 方法来控制是否自动生成绑定列。 例如: 你也可以使用 getDataItem 方法来获取指定行的数据信息。 你可以像这个例子版将数据字段绑定到指定的列:
import { Component, NgModule, enableProdMode } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import '@grapecity-software/spread-sheets-resources-zh'; GC.Spread.Common.CultureManager.culture("zh-cn"); import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; import { SpreadSheetsModule } from '@grapecity-software/spread-sheets-angular'; import GC from '@grapecity-software/spread-sheets'; import './styles.css'; @Component({ selector: 'app-component', templateUrl: 'src/app.component.html' }) export class AppComponent { spread: GC.Spread.Sheets.Workbook; hostStyle = { width: '100%', height: '100%', overflow: 'hidden', float: 'left' }; getProducts(count: number) { const _lines = ["Computers", "Washers", "Stoves"]; const _colors = ["Red", "Green", "Blue", "White"]; const _ratings = ["Terrible", "Bad", "Average", "Good", "Great", "Epic"]; var dataList = []; for (var i = 1; i <= count; i++) { var line = _lines[Math.floor(Math.random() * 3)]; dataList[i - 1] = new Product(i, line, _colors[Math.floor(Math.random() * 4)], line + " " + line.charAt(0) + i, Math.floor(Math.random() * 5001) / 10.0 + 500, Math.floor(Math.random() * 6001) / 10.0, Math.floor(Math.random() * 10001) / 100.0, !!(Math.random() > 0.5), _ratings[Math.floor(Math.random() * 6)]); } return dataList; } initSpread($event: any) { this.spread = $event.spread; let spread = this.spread; spread.suspendPaint(); spread.options.tabStripRatio = 0.8; var products = this.getProducts(100); var sheet = spread.getSheet(0); sheet.name("Default binding"); sheet.setDataSource(products); var sheet2 = spread.getSheet(1); sheet2.name("Custom binding"); sheet2.autoGenerateColumns = false; sheet2.setDataSource(products); var colInfos = [ { name: "id", displayName: "ID" }, { name: "name", displayName: "Name", size: 100 }, { name: "line", displayName: "Line", size: 80 }, { name: "color", displayName: "Color" }, { name: "price", displayName: "Price", formatter: "0.00", size: 80 }, { name: "cost", displayName: "Cost", formatter: "0.00", size: 80 }, { name: "weight", displayName: "Weight", formatter: "0.00", size: 80 }, { name: "discontinued", displayName: "Discontinued", cellType: new GC.Spread.Sheets.CellTypes.CheckBox(), size: 100 }, { name: "rating", displayName: "Rating" } ]; sheet2.bindColumns(colInfos); spread.resumePaint(); } } class Product { id: any; line: string; color: string; name: string; price: number; cost: any; weight: any; discontinued: any; rating: any; constructor(id: any, line: string, color: string, name: string, price: number, cost: any, weight: any, discontinued: any, rating: any) { this.id = id; this.line = line; this.color = color; this.name = name; this.price = price; this.cost = cost; this.weight = weight; this.discontinued = discontinued; this.rating = rating; } } @NgModule({ imports: [BrowserModule, SpreadSheetsModule], declarations: [AppComponent], exports: [AppComponent], bootstrap: [AppComponent] }) export class AppModule { } enableProdMode(); // Bootstrap application with hash style navigation and global services. platformBrowserDynamic().bootstrapModule(AppModule);
