Question

我是JavaScript和Google Apps脚本的新手，所以这绝对是一个'初学者'的问题。我很有信心。

我在电子表格中使用Google Apps脚本来使用onEdit触发器格式化单个单元格。单元格的格式基于来自包含6个按钮的自定义UI应用程序的用户输入。我遇到的问题是onClickHandler函数没有看到最初触发onEdit触发器的相同活动单元格;相反，在Handler中调用的getActiveCell方法返回由于用户按下“Enter”并且活动范围向下移动一个单元格而被编辑的单元格正下方的单元格。

如何让处理程序专注于启动onEdit触发器的同一个单元格？我不确定我是否应该以某种方式将活动单元格从触发onEdit代码的事件通过按钮参数传递给处理程序，或以某种方式获取返回到onEdit代码的值以对那里编辑的单元格进行更改。无论哪种方式是正确的，我都不确定如何去做。

function onEdit(event)
{
  var sheet = event.source.getActiveSheet();
  var cell = sheet.getActiveCell();
  var cellR = cell.getRow();
  var cellC = cell.getColumn();
  var cellValue = cell.getValue();
  var active_spreadsheet = SpreadsheetApp.getActiveSpreadsheet();

  if ((cellR >= 14 && cellR <= 21 && cellC >= 1 && cellC <= 7) ||
           (cellR >= 34 && cellR <= 41 && cellC >= 1 && cellC <= 7)) {

    displayUserOptions();
  }
}

function displayUserOptions()
{
  var app = UiApp.createApplication().setTitle('Choose Equipment Class').setHeight(40).setWidth(350);
  var handler = app.createServerHandler('onClickHandler');
  var button1 = app.createButton('War').setTabIndex(1).setId('war').addClickHandler(handler);
  var button2 = app.createButton('Nature').setTabIndex(2).setId('nature').addClickHandler(handler);
  var button3 = app.createButton('Balance').setTabIndex(3).setId('balance').addClickHandler(handler);
  var button4 = app.createButton('Fortune').setTabIndex(4).setId('fortune').addClickHandler(handler);
  var button5 = app.createButton('Chaos').setTabIndex(5).setId('chaos').addClickHandler(handler);
  var button6 = app.createButton('Generic').setTabIndex(6).setId('generic').addClickHandler(handler);
  var mypanel = app.createHorizontalPanel();
  mypanel.add(button1); mypanel.add(button2); mypanel.add(button3);
  mypanel.add(button4); mypanel.add(button5); mypanel.add(button6);
  app.add(mypanel);

  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  spreadsheet.show(app);

}

function onClickHandler(e) {
  var app = UiApp.getActiveApplication();
  var sheet = SpreadsheetApp.getActiveSheet();
  var cell = sheet.getActiveCell();
  if (e.parameter.source == 'war') {
    Logger.log("War button pressed");
    Browser.msgBox(cell.getValue()); 
    cell.setValue("War!"); // *This string is committing to the wrong cell.
  }
  app.close();
  return app;
}

你可以在你的处理函数中处理它，就像这样：

function onClickHandler(e) {
  var app = UiApp.getActiveApplication();
  var sheet = SpreadsheetApp.getActiveSheet();
  var rowIndex = cell.getRowIndex()-1;
  var colIndex = cell.getColumnIndex();
  sheet.setActiveRange(sheet.getRange(rowIndex,colIndex));
  var cell = sheet.getActiveCell();
  ...

或者你可以在你的Ui中存储单元格的坐标，如下例所示（参见隐藏的小部件和callBackElement）

这样做的好处是，即使用户使用TAB键（或另一个单元格上的mouseClick）来验证他的输入，它也可以工作......所以即使代码更多，我也会推荐这种方法添加; - ）

function onEdit(event){
  var sheet = event.source.getActiveSheet();
  var cell = sheet.getActiveCell();
  var cellR = cell.getRow();
  var cellC = cell.getColumn();
  var cellValue = cell.getValue();
  var active_spreadsheet = SpreadsheetApp.getActiveSpreadsheet();

  if ((cellR >= 14 && cellR <= 21 && cellC >= 1 && cellC <= 7) ||
           (cellR >= 34 && cellR <= 41 && cellC >= 1 && cellC <= 7)) {

    displayUserOptions(cellR,cellC);
  }
}

function displayUserOptions(cellR,cellC){
  var app = UiApp.createApplication().setTitle('Choose Equipment Class').setHeight(40).setWidth(350);
  var mypanel = app.createHorizontalPanel();
  var hidden = app.createHidden('coord').setValue(cellR+'|'+cellC);
  mypanel.add(hidden);
  var handler = app.createServerHandler('onClickHandler').addCallbackElement(mypanel);
  var button1 = app.createButton('War').setTabIndex(1).setId('war').addClickHandler(handler);
  var button2 = app.createButton('Nature').setTabIndex(2).setId('nature').addClickHandler(handler);
  var button3 = app.createButton('Balance').setTabIndex(3).setId('balance').addClickHandler(handler);
  var button4 = app.createButton('Fortune').setTabIndex(4).setId('fortune').addClickHandler(handler);
  var button5 = app.createButton('Chaos').setTabIndex(5).setId('chaos').addClickHandler(handler);
  var button6 = app.createButton('Generic').setTabIndex(6).setId('generic').addClickHandler(handler);
  var mypanel = app.createHorizontalPanel();
  mypanel.add(button1); mypanel.add(button2); mypanel.add(button3);
  mypanel.add(button4); mypanel.add(button5); mypanel.add(button6);
  app.add(mypanel);

  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  spreadsheet.show(app);

}

function onClickHandler(e) {
  Logger.log(Utilities.jsonStringify(e));
  var app = UiApp.getActiveApplication();
  var sheet = SpreadsheetApp.getActiveSheet();
  var rowIndex = Number(e.parameter.coord.split('|')[0]);
  var colIndex = Number(e.parameter.coord.split('|')[1])
  sheet.setActiveRange(sheet.getRange(rowIndex,colIndex));
  var cell = sheet.getActiveCell();
  if (e.parameter.source == 'war') {
  Logger.log("War button pressed");
  Browser.msgBox(cell.getValue()); 
  cell.setValue("War!"); // *This string is committing to the wrong cell.
  }else{
  cell.setBackground('#ffffaa');// just for test to confirm that the right cell has been modified
  }
  app.close();
  return app;
}

注意：如果您希望“活动”单元格没有更改，但仍希望该值出现在正确的单元格中，您可以这样做：

（改变处理函数）

  ... 
  var rowIndex = Number(e.parameter.coord.split('|')[0]);
  var colIndex = Number(e.parameter.coord.split('|')[1])
  var cell = sheet.getRange(rowIndex,colIndex);
  ...

Google Apps脚本Active Cell在调用它的onEdit代码中更改了Handler
