来自可变空白标记的值

Question

我是Google应用程序脚本的初学者。 我想从其他功能的flextable标签中获得价值。我是前主动与setTag（“初始化”）上的doGet（）函数的标签，但是当我叫getTag（），有什么（空白） 这里是我的代码

var SPREADSHEET_ID = "xxx"; 

function doGet(){ 
    var app = UiApp.createApplication().setTitle('Request For Leaving'); 
    var panel = app.createVerticalPanel(); 
    var grid = app.createGrid(4, 4).setId('request'); 

    var employee = gsLibrary.getEmployee(SPREADSHEET_ID); 

    var date1 = new Date(); 
    var preLabel = app.createLabel(': ').setText(': '); 
    var preLabel2 = app.createLabel(': ').setText(': '); 
    var preLabel3 = app.createLabel(': ').setText(': '); 
    var preLabel4 = app.createLabel(': ').setText(': '); 
    var preLabel5 = app.createLabel(': ').setText(': '); 

    var employee = gsLibrary.getEmployee(SPREADSHEET_ID); 
    var idLabel = app.createLabel('Employee ID '); 
    var userIdLabel = app.createLabel(employee.employeeId).setId('userId').setTag(employee.employeeId); 

    var yearLabel = app.createLabel('Year '); 
    var yearDropdown = app.createListBox().setName("yearList").setId("yearList").setWidth('120px'); 

    var statusLabel = app.createLabel('Status '); 
    var statusDropdown = app.createListBox().setName("statusList").setId("statusList").setWidth('120px'); 

    var searchButton = app.createButton("Search").setId("search"); 

    grid.setWidget(0, 0, idLabel) 
    .setWidget(0, 1, preLabel5) 
    .setWidget(0, 2, userIdLabel) 
    .setWidget(1, 0, yearLabel) 
    .setWidget(1, 1, preLabel4) 
    .setWidget(1, 2, yearDropdown) 
    .setWidget(1, 3, searchButton) 
    .setWidget(2, 0, statusLabel) 
    .setWidget(2, 1, preLabel3) 
    .setWidget(2, 2, statusDropdown); 

var flexTable = app.createFlexTable()  
    .setId('myTable') 
    .setTag('init') 
    .setStyleAttribute('border','1px solid black') 
    .setStyleAttribute("left","50px") 
    .setStyleAttribute('borderCollapse','collapse') 
    .setBorderWidth(1) 
    .insertRow(0) 
    .insertCell(0, 0).setStyleAttribute(0,0,"width","20px") 
    .insertCell(0, 1).setStyleAttribute(0,1,"width","80px") 
    .insertCell(0, 2).setStyleAttribute(0,2,"width","70px") 
    .insertCell(0, 3).setStyleAttribute(0,3,"width","70px") 
    .insertCell(0, 4).setStyleAttribute(0,4,"width","500px") 
    .insertCell(0, 5).setStyleAttribute(0,5,"width","50px") 
    .setText(0,0,'No. ') 
    .setText(0, 1,'Leave Day(s)') 
    .setText(0, 2,'Start Date') 
    .setText(0, 3,'End Date') 
    .setText(0, 4,'Description') 
    .setText(0, 5,'Status') 
    .setStyleAttribute('text-align','center').setCellPadding(10).setVisible(true); 

    var searchHandler = app.createServerClickHandler('searchRequestList'); 
    searchHandler.addCallbackElement(panel); 
    searchButton.addClickHandler(searchHandler); 
    setYearList(app,employee); 
    setStatusList(app); 

    panel.add(grid); 
    panel.add(flexTable); 
    app.setStyleAttribute("height","auto"); 
    app.add(panel); 
    return app; 
} 

function setYearList(app,employee){ 
    var yearList = app.getElementById("yearList"); 
    var listYear=getAllYear(employee); 
    var index=0; 
    yearList.addItem("All Year"); 
    for (var i=0;i<listYear.length;i++){ 
    yearList.addItem(listYear[i]); 
    index++; 
    } 

} 

function getAllYear(user){ 
    var AllLeaveObjects = gsLibrary.getAllLeaveRequestByUser(SPREADSHEET_ID, user); 
    var m_yearList=[]; 
    for (var i =0 ;i<AllLeaveObjects.length;i++){ 
    var status=true; 
    var index; 
    index=0; 
    while (status==true && index<=m_yearList.length){ 
     if (gsLibrary.getYear(AllLeaveObjects[i].startDate)==m_yearList[index]){ 
     status =false; 
    } 
     index++;  
    } 
    if (status==true){ 
     m_yearList.push(gsLibrary.getYear(AllLeaveObjects[i].startDate)); 

    } 

    } 

    m_yearList.sort(); 
    return m_yearList; 
} 

function setStatusList(app){ 
var statusList = app.getElementById("statusList"); 
    var allStatus=getAllStatusName(); 
    statusList.addItem("All Status"); 
    for (var i=0;i<allStatus.length;i++){ 
    statusList.addItem(allStatus[i].status); 
    } 
} 

function getAllStatusName(){ 
    var spreadsheetId = SPREADSHEET_ID; 
    var sheet = SpreadsheetApp.openById(spreadsheetId).getSheetByName("Status Request"); 
    var status = gsLibrary.getRowsData(sheet); 
    return status; 
} 

function getStatusNameByNum(num){ 
    var statusName; 

    var allStatusName = getAllStatusName(); 
    for (var i =0 ;i<allStatusName.length;i++){ 
    if (num == allStatusName[i].statusCode){ 
     statusName = allStatusName[i].status; 
    } 
    } 
    return statusName; 
} 

function searchRequestList(e){ 
    var app = UiApp.getActiveApplication(); 
    var employee = gsLibrary.getEmployee(SPREADSHEET_ID); 
    var year=e.parameter.yearList; 
    var status = e.parameter.statusList; 

    fillTable(app,employee,year,status); 
    return app; 
} 

function fill(table, LeaveRequest, index, row, tag){ 
    table.setText(index+1,0,index+1); 
    table.setText(index+1,1,LeaveRequest[row].numberOfDays); 
    table.setText(index+1,2,gsLibrary.convertDate(LeaveRequest[row].startDate)); 
    table.setText(index+1,3,gsLibrary.convertDate(LeaveRequest[row].endDate)); 
    table.setText(index+1,4,table.getTag()); //<--- this is the problem, always blank 
    table.setText(index+1,5,getStatusNameByNum(LeaveRequest[row].status)); 
} 

function setTagTable(){ 
    var app = UiApp.getActiveApplication(); 
    var table = app.getElementById("myTable"); 
    if(table.getTag() == 'init'){ 
    table.setTag() = '1'; 
    }

    var index = 0; 


    if(year == "All Year" && status == "All Status"){ 
     for (var row = 0; row<LeaveRequest.length; row++){ 
     fill(table, LeaveRequest, index, row, ntag); 
     index++;   
     } 
    } 
    else if(year == "All Year"){

     } 
     } 
    } 
    else if(status == "All Status"){

      fill(table, LeaveRequest, index, row, ntag); 
      index++;   
     } 
     } 
    } 
} 

gsLibrary是我创建的库之前，有一个与它没有任何问题...... 谢谢：d

您可以得到任何小部件的标签下面

function doGet(){ 
    ... 
    var lbl = app.createLabel('Hello World').setId('lbl').setTag('tag'); 
    ... 
} 

function handleFunction(e){ 
    /* Some handler function invoked when a button is clicked etc. */ 
    var tag = e.parameter.lbl_tag; 
}
