Show/hide TextBox based on status of RadioButton - textbox

Question

I would like to show "txtElementID" when the radSource4 button is clicked and "txtQuiaLink" and "txtQuiaPass" when the radSource5 button is clicked. How do I go about doing that... I am a little new to Google Apps Script and trying to learn some basics. Thanks

Answer 1

Use ClientHandlers that toggle visibility...
A short example is better than a long explanation, I guess it's clear enough, just insert the following code after you have created all the radioButtons and textBoxes.
DEMO app and full code here
//Client Handlers for textBoxes
var showTxtElementHandler = app.createClientHandler().forTargets(txtElementsID).setVisible(true);
var hideTxtElementHandler = app.createClientHandler().forTargets(txtElementsID).setVisible(false);
radSource4.addClickHandler(showTxtElementHandler);// show when click on radio4
radSource3.addClickHandler(hideTxtElementHandler);// hide if click other
radSource5.addClickHandler(hideTxtElementHandler);
var showtxtQuiaLinkHandler = app.createClientHandler().forTargets(txtQuiaLink).setVisible(true);
var hidetxtQuiaLinkHandler = app.createClientHandler().forTargets(txtQuiaLink).setVisible(false);
radSource5.addClickHandler(showtxtQuiaLinkHandler);// show when clicked on radio5
radSource3.addClickHandler(hidetxtQuiaLinkHandler);// hide in other cases
radSource4.addClickHandler(hidetxtQuiaLinkHandler);
EDIT : did you mean something like this ? :
in this case I did it with an horizontal panel like below (demo updated)
var txtRadioGrp1 = app.createTextBox().setName('txtRadioGrp1').setVisible(false);
var txtRadioGrp2 = app.createTextBox().setName('txtRadioGrp2').setVisible(false);
var txtElementsID = app.createTextBox().setName('txtElementsID');
var txtQuiaLink = app.createTextBox().setName('txtQuiaLink');
var txtElementsIDP = app.createHorizontalPanel().add(app.createLabel('enter a value')).add(txtElementsID).setVisible(false);
var txtQuiaLinkP = app.createHorizontalPanel().add(app.createLabel('enter a value')).add(txtQuiaLink).setVisible(false);
var txtQuiaPass = app.createTextBox().setName('txtQuiaPass').setVisible(false);
//Create Source Radio Button Group
var radSource1 = app.createRadioButton('group1', 'Hard-Copy').setFormValue('Hard-Copy').addClickHandler(app.createClientHandler().forTargets(txtRadioGrp1).setText('Hard-Copy'));
var radSource2 = app.createRadioButton('group1', 'Electronic-Copy').setFormValue('Electronic-Copy').addClickHandler(app.createClientHandler().forTargets(txtRadioGrp1).setText('Electronic-Copy'));
//Create Type Radio Button Group
var radSource3 = app.createRadioButton('group2', 'Teacher-Made Exam').setFormValue('Teacher-Made Exam').addClickHandler(app.createClientHandler().forTargets(txtRadioGrp2).setText('Teacher-Made Exam'));
var radSource4 = app.createRadioButton('group2', 'Elements Exam').setFormValue('Elements Exam').addClickHandler(app.createClientHandler().forTargets(txtRadioGrp1).setText('Elements Exam'));
var radSource5 = app.createRadioButton('group2', 'Quia Exam').setFormValue('Quia Exam').addClickHandler(app.createClientHandler().forTargets(txtRadioGrp1).setText('Quia Exam'));
var btnCreate = app.createButton('Create Event');
//Client Handlers for textBoxes
var showTxtElementHandler = app.createClientHandler().forTargets(txtElementsIDP).setVisible(true);
var hideTxtElementHandler = app.createClientHandler().forTargets(txtElementsIDP).setVisible(false);
radSource4.addClickHandler(showTxtElementHandler);
radSource3.addClickHandler(hideTxtElementHandler);
radSource5.addClickHandler(hideTxtElementHandler);
var showtxtQuiaLinkHandler = app.createClientHandler().forTargets(txtQuiaLinkP).setVisible(true);
var hidetxtQuiaLinkHandler = app.createClientHandler().forTargets(txtQuiaLinkP).setVisible(false);
radSource5.addClickHandler(showtxtQuiaLinkHandler);
radSource3.addClickHandler(hidetxtQuiaLinkHandler);
radSource4.addClickHandler(hidetxtQuiaLinkHandler);
EDIT 2 : GRID version
//Add all the elemnts to the panel
var grid = app.createGrid(12,2).setCellPadding(5);
vertMainPanel.add(grid);
grid.setWidget(0,0,lblTeacherName)
.setWidget(0,1,txtTeacherName)
.setWidget(1,0,lblExt)
.setWidget(1,1,txtExt)
.setWidget(2,0,lblDate)
.setWidget(2,1,boxDate)
.setWidget(3,1,lbxSubject)
.setWidget(3,0,lbxPeriod)
.setWidget(4,0,lblStudentNum)
.setWidget(4,1,txtStudentNum)
.setWidget(5,0,radSource1)
.setWidget(5,1,radSource2)
.setWidget(6,0,txtRadioGrp1)
.setWidget(7,0,radSource3)
.setWidget(8,0,radSource4)
.setWidget(8,1,txtElementsIDP)
.setWidget(9,0,radSource5)
.setWidget(9,1,txtQuiaLinkP)
.setWidget(10,0,txtQuiaPass)
.setWidget(10,1,txtRadioGrp2)
.setWidget(11,0,btnCreate);
