状态栏

状态栏可以使用自定义的状态栏项目显示集算表的数据以及状态。例如,双击任何单元格以查看状态栏消息更改为编辑。

状态栏可以显示各种各样的表单状态以及总计值。选择不同区域的单元格来查看状态栏中的信息是如何改变的。 以下是示例代码:
/*REPLACE_MARKER*/ /*DO NOT DELETE THESE COMMENTS*/ var tableName = "Customer"; var baseApiUrl = getBaseApiUrl(); var apiUrl = baseApiUrl + "/" + tableName; var myView; window.onload = function() { var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 0 }); var statusBar = initStatusBar(spread); initSpread(spread, statusBar); }; function initSpread(spread, statusBar) { spread.suspendPaint(); spread.options.autoFitType = GC.Spread.Sheets.AutoFitType.cellWithHeader; //init a data manager var dataManager = spread.dataManager(); //add customer table var customerTable = dataManager.addTable("myTable", { remote: { read: { url: apiUrl } } }); //init a table sheet var sheet = spread.addSheetTab(0, "TableSheet1", GC.Spread.Sheets.SheetType.tableSheet); sheet.options.allowAddNew = false; //hide new row //bind a view to the table sheet myView = customerTable.addView("myView", [ { value: "Id", width: 80 }, { value: "CompanyName", width: 200, caption :"Company Name" }, { value: "ContactName", width: 150, caption :"Contact" }, { value: "ContactTitle", width: 200, caption :"Title" }, { value: "Address", width: 200 }, { value: "City", width: 150, caption :"City" }, { value: "State", width: 100, caption :"State" }, { value: "Region", width: 100, caption :"Region" } ]); myView.fetch().then(function() { sheet.setDataView(myView); if (statusBar) { var recordItem = statusBar.get("recordCountItem"); if (recordItem) { recordItem.dataSourceLength = myView.length(); recordItem.visibleLength = myView.visibleLength(); recordItem.onUpdate(); } } }); spread.resumePaint(); } function initStatusBar(spread) { //define custom status item var StatusItem = GC.Spread.Sheets.StatusBar.StatusItem; function RecordCountItem(name, options) { StatusItem.call(this, name, options); this._value = 1; this.dataSourceLength = 0; this.visibleLength = 0; } RecordCountItem.prototype = new StatusItem(); RecordCountItem.prototype.onCreateItemView = function(container) { var element = this._element; if (!element) { element = this._element = document.createElement("span"); element.innerHTML = " Rows: <b>" + this.visibleLength + "</b> of <b>" + this.dataSourceLength + "</b> - Record Count: <b>" + this._value + "</b>"; } container.appendChild(element); }; RecordCountItem.prototype.onBind = function(context) { var _this = this; context.bind(GC.Spread.Sheets.Events.SelectionChanged, function(e, args) { _this._value = getRowCount(args.newSelections); _this.onUpdate(); }); context.bind(GC.Spread.Sheets.Events.RangeFiltered, function (e, args) { _this.dataSourceLength = myView.length(); _this.visibleLength = myView.visibleLength(); _this.onUpdate(); }); context.bind(GC.Spread.Sheets.Events.RangeFilterCleared, function (e, args) { _this.dataSourceLength = myView.length(); _this.visibleLength = myView.visibleLength(); _this.onUpdate(); }); }; RecordCountItem.prototype.onUpdate = function() { StatusItem.prototype.onUpdate.call(this); this._element.innerHTML = " Rows: <b>" + this.visibleLength + "</b> of <b>" + this.dataSourceLength + "</b> - Record Count: <b>" + this._value + "</b>"; }; //init status bar var recordCountItem = new RecordCountItem('recordCountItem', { menuContent: 'Record Count', value: 0 }); var statusBar = new GC.Spread.Sheets.StatusBar.StatusBar(document.getElementById('statusBar'), { items: [recordCountItem] }); statusBar.bind(spread); return statusBar; } function getRowCount(selections) { var selectedRows = {}; for (var i = 0; i < selections.length; i++) { var row = selections[i].row; var rowCount = selections[i].rowCount; if (row === -1) { return rowCount; } for (var c = 0; c < rowCount; c++) { selectedRows[row + c] = true; } } return Object.keys(selectedRows).length; } function getBaseApiUrl() { return window.location.href.match(/http.+spreadjs\/SpreadJSTutorial\//)[0] + 'server/api'; }
