方法详细信息
load(options)
将命令加入队列以加载对象的指定属性。 阅读属性前必须先调用 context.sync()。
load(options?: Excel.Interfaces.ChartDataLabelsLoadOptions): Excel.ChartDataLabels;参数
为要加载的对象属性提供选项。
返回
load(propertyNames)
将命令加入队列以加载对象的指定属性。 阅读属性前必须先调用 context.sync()。
load(propertyNames?: string | string[]): Excel.ChartDataLabels;参数
- propertyNames
-
string | string[]
指定要加载的属性的逗号分隔的字符串或字符串数组。
返回
示例
// Show the series name in data labels and set the position of the data labels to "top".
await Excel.run(async (context) => {
const chart = context.workbook.worksheets.getItem("Sheet1").charts.getItem("Chart1");
chart.dataLabels.showValue = true;
chart.dataLabels.position = Excel.ChartDataLabelPosition.top;
chart.dataLabels.showSeriesName = true;
await context.sync();
console.log("Data labels shown");
});
load(propertyNamesAndPaths)
将命令加入队列以加载对象的指定属性。 阅读属性前必须先调用 context.sync()。
load(propertyNamesAndPaths?: {
select?: string;
expand?: string;
}): Excel.ChartDataLabels;参数
- propertyNamesAndPaths
-
{ select?: string; expand?: string; }
propertyNamesAndPaths.select 是指定要加载的属性的逗号分隔字符串，以及 propertyNamesAndPaths.expand 指定要加载的导航属性的逗号分隔字符串。
返回
set(properties, options)
同时设置对象的多个属性。 可以传递具有相应属性的纯文本对象，也可以传递另一个相同类型的 API 对象。
set(properties: Interfaces.ChartDataLabelsUpdateData, options?: OfficeExtension.UpdateOptions): void;参数
- properties
- Excel.Interfaces.ChartDataLabelsUpdateData
一个 JavaScript 对象，其属性与调用该方法的对象的属性同构结构。
- options
- OfficeExtension.UpdateOptions
提供一个选项，用于在 properties 对象尝试设置任何只读属性时禁止错误。
返回
void
set(properties)
基于现有加载的对象，同时在对象上设置多个属性。
set(properties: Excel.ChartDataLabels): void;参数
- properties
- Excel.ChartDataLabels
返回
void
toJSON()
覆盖 JavaScript toJSON() 方法，以便在将 API 对象传递给 JSON.stringify()时提供更有用的输出。 (JSON.stringify反过来调用 toJSON 传递给它的对象的方法。) 虽然原始 Excel.ChartDataLabels 对象是 API 对象， toJSON 但该方法返回一个纯 JavaScript 对象， (类型化为 Excel.Interfaces.ChartDataLabelsData) ，其中包含从原始对象加载的任何子属性的浅层副本。
toJSON(): Excel.Interfaces.ChartDataLabelsData;
