按鈕單擊更改電子表格中的行

Question

當您單擊按鈕時，如何添加或減去數字。我想簡單地說

if (button.click){ 
    num++; 
} 

我該如何用google apps腳本按鈕做類似的事情？事情似乎沒那麼直截了當，因爲我從來沒有使用過點擊處理程序。它可能是我錯過的一些簡單的事情。謝謝您的幫助。

請看看這個演示代碼：

var sh = SpreadsheetApp.getActiveSheet(); 
var ss = SpreadsheetApp.getActiveSpreadsheet(); 
// 
function move() { 
    var app = UiApp.createApplication().setTitle("move test") 
     .setHeight(100).setWidth(400).setStyleAttribute("background-color","beige"); 
    var panel = app.createVerticalPanel(); 
    var next = app.createButton('next').setWidth('180'); 
    var chkmode = app.createCheckBox("moving mode (checked = up/dwn, unchecked=L/R)").setValue(false).setName('chkmode'); 
    panel.add(next).add(chkmode); 
    var handler = app.createServerHandler('click').addCallbackElement(panel); 
    next.addClickHandler(handler); 
    app.add(panel); 
    ss.show(app); 
} 
// 
function click(e) { 
    var app = UiApp.getActiveApplication(); 
    var activeline = sh.getActiveRange().getRow();// get the row number of the selected cell/range 
    var activecol = sh.getActiveRange().getColumn();// get the row number of the selected cell/range 
    var chkmode=e.parameter.chkmode;// this returns a string, that's why true is written "true" just below... 
    if(chkmode=="true"){ 
    ++activeline 
    }else{ 
     ++activecol} // the ++ can be before or after the var name, your choice ;-) 
    var sel=sh.getRange(activeline,activecol); 
    sh.setActiveSelection(sel);// make the next row or column active 
    return app; 
} 

編輯：（以下次要問題）來獲取標籤顯示單元格的內容，您可以在處理函數中使用此代碼：

function click(e) { 
    var app = UiApp.getActiveApplication(); 
    var activeline = sh.getActiveRange().getRow();// get the row number of the selected cell/range 
    var activecol = sh.getActiveRange().getColumn();// get the row number of the selected cell/range 
    var cellvaluestring = sh.getActiveRange().getValue().toString(); 
    var label = app.getElementById('label'); 
    label.setText(cellvaluestring); 
    var chkmode=e.parameter.chkmode; 
    if(chkmode=="true"){ 
    activeline++ 
    }else{ 
     activecol++} 
    var sel=sh.getRange(activeline,activecol); 
    sh.setActiveSelection(sel);// make the next row active 
    return app; 
} 

，並在UI定義你要創建這樣的標籤：

var label = app.createLabel("test Label with text that will be modified on click").setId('label'); 
    panel.add(label);
