关系视图

TableSheet可以在同一个视图内绑定多个关系表。

要将多个表绑定到一个视图,用户只需要执行以下3个步骤: 将多个表添加到DataManager 在这些表之间添加关系 添加自定义视图 以下是示例代码:
window.onload = function() { var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 0 }); initSpread(spread); }; function initSpread(spread) { spread.suspendPaint(); spread.options.autoFitType = GC.Spread.Sheets.AutoFitType.cellWithHeader; spread.bind(GC.Spread.Sheets.Events.EditStarting, function (e, args) { if (args.sheet.getValue(0, args.col, GC.Spread.Sheets.SheetArea.colHeader) === 'customer'){ args.cancel = true; } }); //init a data manager var baseApiUrl = getBaseApiUrl(); var dataManager = spread.dataManager(); //add order table var orderTable = dataManager.addTable("orderTable", { remote: { read: { url: baseApiUrl + "/Order" } } }); //add customer table var customerTable = dataManager.addTable("customerTable", { remote: { read: { url: baseApiUrl + "/Customer" } } }); //add relationship between order table and customer table dataManager.addRelationship(orderTable, "CustomerId", "customer", customerTable, "Id", "orders"); //init a table sheet var sheet = spread.addSheetTab(0, "TableSheet1", GC.Spread.Sheets.SheetType.tableSheet); sheet.options.allowAddNew = false; //hide new row sheet.actionColumn.options({ visible: false }); //hide action column //bind a view to the table sheet var style = { formatter: 'Ship To: {{=CONCAT(PROPERTY(@, "ShipAddress"), ", ", PROPERTY(@, "ShipCity"))}}' }; var selectView = customerTable.addView("customersView", [ { value: 'Id' }, { value: 'CompanyName' }, { value: 'ContactName' }, { value: 'ContactTitle' }, ]); var multiSelectStyle = { formatter: '{{=CONCAT(PROPERTY(@, "CompanyName"), ", ", PROPERTY(@, "ContactName"))}}', // convert the object to string cellButtons: [ { imageType: "dropdown", command: "openMultiColumn", useButtonStyle: true, } ], dropDowns: [ { type: "multiColumn", option: { width: 400, height: 400, dataSource: selectView, bindingInfos: [ { name: "Id", size: 60 }, { name: "CompanyName", size: "*" }, { name: "ContactName", size: "*" }, ] } } ] }; var myView = orderTable.addView("myView", [ { value: "Id", width: 100 }, //set column width 100px { value: "OrderDate", width: 200, style: { formatter: "MM/dd/yyyy" } }, { value: "Freight", width: 100 }, /** * customer.companyName - this is a related field from the customer table * update the customerId in orderTable by select from customer table. */ { value: "customer", width: 350, style: multiSelectStyle }, /** * [=@] this column will contain the full row as a value, the formatter formula will extract the shipping address from the full row. * Format functions can be used to customize column display value * use star-size "2*" to set column width relative to the viewport width */ { value: "=[@]", caption: "Address", style: style, width: "2*" } ]); myView.fetch().then(function() { sheet.setDataView(myView); }); spread.resumePaint(); } function getBaseApiUrl() { return window.location.href.match(/http.+spreadjs\/SpreadJSTutorial\//)[0] + 'server/api'; }
