如何將輸入值傳遞給使用GAS的函數

Question

我會盡量保持簡短。我試圖在谷歌電子表格中制​​作一個谷歌網絡應用程序，它將允許我輸入最小值和最大值。

我已經能夠創建GUI並將其添加到面板。但我似乎無法將正在輸入的整數傳遞到另一個函數中。我已經嘗試了所有的東西，我對創建Google腳本相對來說比較陌生，所以我很抱歉，如果這看起來有些不好的問題。

這是迄今爲止所有代碼：

function onOpen() { 
    var ss = SpreadsheetApp.getActive(); 
    var menuEntries = []; 
    menuEntries.push({name: "Open Dialog", functionName: "showDialog"}); 
    ss.addMenu("Min/Max", menuEntries); 
} 


//creating a panel to add the min and max of low to high for scoring 
function showDialog() { 
    max = 10; 
var app = UiApp.createApplication(); 
app.setTitle("My Applicaition"); 
    var panel = app.createVerticalPanel(); 
    var textBox = app.createTextBox(); 
    var label = app.createLabel("Set the min value for 'Low'"); 
    //had to create a hidden element with id="min" for a global value that can be updated 
    var min = app.createHidden().setValue('0').setName('min').setId('min'); 
    textBox.setName('myTextBox').setId('myTextBox'); 
    var button = app.createButton('Submit'); 
    panel.add(label); 
    panel.add(textBox); 
    panel.add(min); 
    panel.add(button); 


    //click handler for setting the value of min to the new value 
    var clickHandler = app.createServerClickHandler("responedToSubmit"); 
    button.addClickHandler(clickHandler); 
    clickHandler.addCallbackElement(panel); 
    app.add(panel); 

    var doc = SpreadsheetApp.getActive(); 
    doc.show(app); 
} 

function responedToSubmit(e) { 
    var app = UiApp.getActiveApplication(); 
    var textBoxValue = e.parameter.myTextBox; 
    Logger.log(e.parameter.min); 
    if (typeof textBoxValue != "number") { 
    var num = parseInt(textBoxValue); 
    app.getElementById('min').setValue(num); 
    Logger.log("textBoxValue is = "+textBoxValue+"\n min value is = "+e.parameter.min); 
    } else { 
    throw "value needs to be set as number"; 
    } 
    return app.close(); 
} 

這是我相信事情正在按計劃不會：

function responedToSubmit(e) { 
    var app = UiApp.getActiveApplication(); 
    var textBoxValue = e.parameter.myTextBox; 
    Logger.log(e.parameter.min); 
    if (typeof textBoxValue != "number") { 
    var num = parseInt(textBoxValue); 
    app.getElementById('min').setValue(num); 
    Logger.log("textBoxValue is = "+textBoxValue+"\n min value is = "+e.parameter.min); 
    } else { 
    throw "value needs to be set as number"; 
    } 
    return app.close(); 
} 

我發現，每次我測試.setValue （）不會更新'min'的值，我不明白爲什麼。你能幫忙嗎？

您需要將textBox元素添加到clickHandler的callBack元素列表中。 試試這個：

//click handler for setting the value of min to the new value 
var clickHandler = app.createServerClickHandler("responedToSubmit"); 
clickHandler.addCallbackElement(panel); 
clickHandler.addCallbackElement(textBox); 
button.addClickHandler(clickHandler); 
app.add(panel);
