GcExcel 中有模板语法这个功能,通过一个模板在后端根据数据源去生成一个指定的表单,非常方便快捷。
在前端 SpreadJS,也有区域模板这一功能,但是他是一个单元格类型,且无法直接编辑与导出 Excel。
这篇教程就来实现一个利用数据绑定实现的自定制区域模板功能。可以先看下效果。
首先,我们先设计上一个需要填报或者绑定的模板
加载完模板后,我们定义了一些数据源。
var score = [
{ class: "A班", name: "小明", cn: 88, ma: 69, en: 77 },
{ class: "A班", name: "小红", cn: 90, ma: 87, en: 80 },
{ class: "B班", name: "小张", cn: 60, ma: 68, en: 71 },
{ class: "B班", name: "小焦", cn: 95, ma: 88, en: 79 },
{ class: "C班", name: "小绿", cn: 57, ma: 66, en: 68 },
{ class: "C班", name: "小菊", cn: 79, ma: 69, en: 71 },
];
接下来的重头戏就是绑定,我们通过遍历,给将数据源一次一次地给数据源进行绑定,然后将新绑定的表单通过copyTo的接口复制到下一个区域,直至将数据源遍历完。最后再通过deleteRows将初始的模板删除。
for (var i = 0; i < score.length; i++) {
var data = score[i];
var source = new GC.Spread.Sheets.Bindings.CellBindingSource(data);
sheet.setDataSource(source);
sheet.copyTo(
1,
1,
7 * (i + 1) - i,
1,
5,
4,
1 | 2 | 4 | 8 | 16 | 32 | 64 | 128 | 512 | 1024
);
}
sheet.deleteRows(1, 6);
我们也可以通过导出excel的按钮将这个表单导出。
