如何在Javascript中将多个json对象数组传递给模拟软报表

Question

我用javascript编写了以下代码：

var viewer = new window.Stimulsoft.Viewer.StiViewer(
  null,
  "StiViewer",
  false
);

var report = new window.Stimulsoft.Report.StiReport();
const { data: reportData } = await GetRequestFromStore(
  this.state.reportDate,
  this.state.storeId
);

var json = {
  DataSet: reportData.requestItems,
};
var dataSet = new window.Stimulsoft.System.Data.DataSet("JSON");
dataSet.readJson(json);
report.regData("JSON", "JSON", dataSet);

report.loadFile(this.state.reportName);
report.dictionary.variables.getByName(
  "requestDate"
).valueObject = this.state.jalaaliReportDate;

viewer.report = report;

viewer.renderHtml("viewer");

并在stimulsoft中进行数据源的设计

如何在代码中将Items对象数组和Description对象数组传递给报表。谢谢。

DataSet With Two Tables解决了我的问题。我已经将两个JSON对象数组组合成一个JSON对象，并注册了dataset。

现在，reportData是这样的：

let reportData = {
  items: [],
  descriptions: [],
};

Stimulsoft designer中的dataSet设计是：

这部分代码对我来说是有效的。

var viewer = new window.Stimulsoft.Viewer.StiViewer(null, "Viewer", false);

var report = new window.Stimulsoft.Report.StiReport();
const { data: reportData } = await GetRequestFromStore(
  this.state.reportDate,
  this.state.storeId
);

var dataSet = new window.Stimulsoft.System.Data.DataSet("DS1");
dataSet.readJson(JSON.stringify(reportData));//one JSON object

//this line of code added,too.
report.dictionary.databases.clear();
report.regData("DS1", "DS1", dataSet);

//this line of code is also required.
report.dictionary.synchronize();

report.loadFile(this.state.reportName);
report.dictionary.variables.getByName(
  "requestDate"
).valueObject = this.state.jalaaliReportDate;

viewer.report = report;

viewer.renderHtml("viewer");
