我遇到与this question类似的问题 - 但我需要获得2个 第1和第2个列表框的e参数,以便填充第3个电子表格列表框。
e.parameter正在读取vert
,但chan
未定义,我不明白,因为它在第二个列表框中完全正常,但不是第三个。
我在这段代码中有监督的东西吗?
var channelBox = app.createListBox().setId('channelBox').setName('channelBox').setWidth(152).setHeight(22);
var chanHandler = app.createServerChangeHandler('showChannelinfo');
chanHandler.addCallbackElement(channelBox);
channelBox.addChangeHandler(chanHandler);
var chaArray = ['Select channel','--','Email','Phone','Chat']; for (var i=0;i<chaArray.length;++i) {channelBox.addItem(chaArray[i]);};
var verticalBox = app.createListBox().setId('verticalBox').setName('verticalBox').setWidth(152).setHeight(22);
var vertHandler = app.createServerChangeHandler('showVerticalinfo');
vertHandler.addCallbackElement(verticalBox);
verticalBox.addChangeHandler(vertHandler);
function showChannelinfo(e){
var app = UiApp.getActiveApplication();
var itemSpreadsheetKey = 'ABC------------123';
var openedSS = SpreadsheetApp.openById(itemSpreadsheetKey);
var sheetList3 = openedSS.getSheetByName("boolean3");//Vertical Lookup Sheet
var channelBox = app.getElementById('channelBox');
var verticalBox = app.getElementById('verticalBox');
var chan = e.parameter.channelBox;
if (chan == 'Phone')
{ verticalBox.clear();
var marketFilter = sheetList3.getRange('A1').setFormula('=iferror(filter(boolean2!A:D,boolean2!B:B=TRUE))');}
if (chan == 'Email')
{ verticalBox.clear();
var marketFilter = sheetList3.getRange('A1').setFormula('=iferror(filter(boolean2!A:D,boolean2!D:D=TRUE))');}
if (chan == 'Chat')
{ verticalBox.clear();
var marketFilter = sheetList3.getRange('A1').setFormula('=iferror(filter(boolean2!A:D,boolean2!C:C=TRUE))');}
var numItemList1 = sheetList3.getLastRow();//get the item array
var list1ItemArray = sheetList3.getRange(1,1,numItemList1).getValues();//Add the items in ListBox
for(var i=0; i<list1ItemArray.length; i++)
{verticalBox.addItem(list1ItemArray[i][0]);}
if (chan == '--')
{verticalBox.clear();
var vertArray = ['Select vertical','Hardware','Apps','Ebooks','Movies','Music','Nik','Shopping','Places','Wallet','YouTube','BeatThatQuote'];
for (var i=0;i<vertArray.length;++i) {verticalBox.addItem(vertArray[i]);};}
return app
};
function showVerticalinfo(e){
var app = UiApp.getActiveApplication();
var itemSpreadsheetKey = 'ABC------------123';
var openedSS = SpreadsheetApp.openById(itemSpreadsheetKey);
var sheetList4 = openedSS.getSheetByName("boolean4");//Language Lookup Sheet
var channelBox = app.getElementById('channelBox');
var verticalBox = app.getElementById('verticalBox');
var langBox = app.getElementById('langBox');
var chan = e.parameter.channelBox;
var vert = e.parameter.verticalBox;
langBox.clear();
var langFilter = sheetList4.getRange('A1').setFormula('=iferror(filter(boolean!A:D,boolean!A:A="' + chan + '",boolean!B:B="' + vert + '",boolean!D:D=TRUE))');
//**this returns as chan = undefined**
var numItemList2 = sheetList4.getLastRow();//get the item array
var list1ItemArray2 = sheetList4.getRange(1,3,numItemList2).getValues();//Add the items in ListBox
for(var i=0; i<list1ItemArray2.length; i++){langBox.addItem(list1ItemArray2[i][0]);}
if (chan == '--')
{langBox.clear();
var langArray = ['Select language','Dutch','French','German','Italian','Portuguese', 'Russian','Spanish'];
for (var i=0;i<langArray.length;++i) {langBox.addItem(langArray[i]);};}
return app
};
如果有人能用他们的魔眼给我任何建议,我们将不胜感激!

问题在于你的callbackElement。 我建议您将这两个列表框放在一个面板中,并将此面板作为回调元素添加到两个处理程序中。像
这样的东西function doGet(){
/* Your other code here */
var panel = app.createVerticalPanel().setId('panel');
var channelBox = app.createListBox().setId('channelBox').setName('channelBox').setWidth(152).setHeight(22);
var chanHandler = app.createServerChangeHandler('showChannelinfo');
chanHandler.addCallbackElement(panel); /* Add panel as the callback element */
channelBox.addChangeHandler(chanHandler);
var chaArray = ['Select channel','--','Email','Phone','Chat']; for (var i=0;i<chaArray.length;++i) {channelBox.addItem(chaArray[i]);};
var verticalBox = app.createListBox().setId('verticalBox').setName('verticalBox').setWidth(152).setHeight(22);
var vertHandler = app.createServerChangeHandler('showVerticalinfo');
vertHandler.addCallbackElement(panel); /* Add panel as the callback element */
verticalBox.addChangeHandler(vertHandler);
panel.add(channelBox);
panel.add(verticalBox);
/* Your other UI Code here */
}
