我已經編寫了一個Google應用程序腳本,它首先在UI應用程序中創建並顯示折線圖,然後根據選定列表框值重新繪製圖形點擊按鈕事件處理程序在圖形「刷新」時觸發。GAS單擊事件處理程序在用戶界面Web應用程序中導致「意外錯誤」
我試圖解決的問題是,當作爲Web應用程序發佈時,我在觸發點擊事件時收到Error Encountered: An unexpected error occurred
。
該代碼可以從電子表格中完美運行(除了一些討厭的權限問題,其他用戶被要求下載面板對象;我將在後面討論),而且我爲什麼贏了' t翻譯。
下面的代碼爲它的價值:
function doGet(){
var app = UiApp.createApplication().setWidth(800).setHeight(650).setTitle('FLEET Chart');
var e = 'undefined';
lb(app);
return click(e, app);
}
function lb(app){
var lb = app.createListBox(true).setId('myId').setName('myLbName');// add items to ListBox
var lb2 = app.createListBox(true).setId('myId2').setName('myLbName2');
var lb3 = app.createListBox(true).setId('myId3').setName('myLbName3');
var bttn = app.createButton('Refresh').setId('myBttn');
lb3.addItem('2011').addItem('2012');
lb2.addItem('January')
.addItem('February')
.addItem('March')
.addItem('April')
.addItem('May')
.addItem('June')
.addItem('July')
.addItem('August')
.addItem('September')
.addItem('October')
.addItem('November')
.addItem('December');
lb.addItem('Drug1')
.addItem('Drug2')
.addItem('Drug3')
.addItem('Drug4');
var mypanel = app.createHorizontalPanel().setVisible(true);
mypanel.add(lb).add(lb2).add(lb3).add(bttn);
app.add(mypanel);
var handler = app.createServerChangeHandler('click').addCallbackElement(mypanel);
handler.addCallbackElement(bttn);
bttn.addClickHandler(handler);
}
function click(e, app) {
var valuelb = new Array('Drug1','Drug2','Drug3','Drug4');
var valuelb2 = new Array ('January','February','March','April','May','June','July','August','September','October','November','December');
var valuelb3 = new Array('2011','2012');
var SS = SpreadsheetApp.openById('0Am8DRqAEaxH7dF9NWFJLSTdWZGRxeEFfMkFjNlFCT2c');
var sheeteff = SS.getSheetByName('Efficiency');
var data = sheeteff.getDataRange().getValues();
if (String(e) != 'undefined') {
app.setWidth(800).setHeight(650).setTitle('FLEET Chart');
var valuelb = String(e.parameter.myLbName);
if (valuelb.indexOf(',') != -1) {
var valuelb = e.parameter.myLbName.split(',');

}
SS.getSheetByName('Sheet2').getRange(1,1).setValue(String(valuelb2) + ' ' + valuelb.indexOf(','));//for unformation purposes
lb(app);
}else{
SS.getSheetByName('Sheet2').getRange(1,1).setValue(String(e));//for information purposes
}
var usedata = ArrayLib.filterByText(ArrayLib.filterByText(ArrayLib.filterByText(data, 3, valuelb), 1, valuelb2), 0, valuelb3);
//Build data table
var dataTable = Charts.newDataTable();
//Add Column types
dataTable.addColumn(Charts.ColumnType.DATE, data[0][2]);
dataTable.addColumn(Charts.ColumnType.NUMBER, data[0][9]);
dataTable.addColumn(Charts.ColumnType.NUMBER, data[0][8]);
//Add rows
for(var j=0; j<usedata.length; j++){
dataTable.setValue(j, 0, usedata[j][2]);
dataTable.setValue(j, 1, usedata[j][9]);
dataTable.setValue(j, 2, usedata[j][8]);
}
//Create and build chart
var chart = Charts.newLineChart()
.setDataTable(dataTable)
.setTitle('Efficiency over Time \nConfiguration: [' + valuelb + ']\n' + 'Month: [' + valuelb2 + ']\n' + 'Year: [' + valuelb3 + ']')
.setXAxisTitle('Time')
.setYAxisTitle('Percentage')
.setDimensions(750, 600)
.setPointStyle(Charts.PointStyle.MEDIUM)
.build();
app.add(chart);
return app;
}
感謝斯里蘭卡, 我已經刪除除了最初的一個createApplication方法,並設置處理程序來調用click(e)函數;這實際上是如何設定的,但我一直在弄清楚什麼是錯。 唉...仍然沒有刷新。 Regards, Ryan – user1579717 2012-08-06 18:43:19
好的,在這種情況下,您應該在點擊(e)代碼中執行var app = UiApp.getActiveApplication()。 – Srik 2012-08-07 04:19:58
