Can somebody please help me to create a mandatory radio button in JSP?
Idea is to prompt the user to check the radio box when he parses through the page, and once he checks either of the radio button (Yes or No) we capture the value and save it to Db.
By default radio should be blank it should be blank.
Embedded a piece of Javascript in your page, upon form submission, the Javascript validates radiobutton value like this:
How can I check whether a radio button is selected with JavaScript?
if(document.getElementById('gender_Male').checked) {
//Male radio button is checked
} else if(document.getElementById('gender_Female').checked) {
//Female radio button is checked
} else {
alert('You should select a radio button!');
}

I started creating an automation framework for my current company. now I’m having a problem with a form that has a JS modal appearing top part of the form attaches to it. that JS form comes every time if I change the default value of the form (Changes Detected: save button, dismissed button). the issue is there is a drop-down box and the default value is set to empty. after I change that to a value (eg: house) that JS modal comes that I have made a change to the form and put the value of the drop-down box to that default empty value. this happens in the run time. if I put a thread.sleep for 3 seconds that solves the issue. but I need a more reliable solution. are there any other options that I can use for this issue?
All I can think of now is to call that first function, Wait for success
WebDriverWait wait = new WebDriverWait(driver, 5);
wait.until(ExpectedConditions.javaScriptThrowsNoExceptions("putValue()"));
May be a little bit

I've created a JComboBox that gets populated with an arraylist of strings. My comboBox gets populated correctly just as I want. My problem comes when getting the selected item: As I print it in a btnGo.addActionListener I realize that it is always the same one selected, even though I change the selection and click Go again. Is there a way to make the selection actually change? And can I do the same without having to click Go? Like just selecting the item from the comboBox and instantly do the action.
This is how I check what item is getting selected:
String selected = comboBox.getSelectedItem().toString();
And then I print selected in the btnGo.addActionListener
yes it's possible to execute an action when a comboBox element is selected. You just need to add an ActionListener to your comboBox ; here is a sample code :
comboBox.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
JComboBox comboBox = (JComboBox) event.getSource();
Object selected = comboBox.getSelectedItem();
if(selected.toString().equals("item1"))
field.setText("AA");
else if(selected.toString().equals("item2"))
field.setText("BB");
}
});
getContentPane().add(comboBox);
getContentPane().add(field);
}
Please share source code in order to help you with the selection issue.

We use a sortable CellTable with two columns, with a SingleSelectionModel.
Now one of the columns is filled with ButtonCells.
And the problem is: if I click the first time directly on the button of a row, only the row gets selected and it doesn't directly fires the Event for the Button. I have to click a second time.
How can I change this? How can I directly fire the event of the Button?
You can set a FieldUpdater on your Button Column:
column.setFieldUpdater(new FieldUpdater<Auction, String>() {
#Override
public void update(int index, Auction object, String value) {
// The user clicked on the button for the passed auction.
}
});
The CellSampler from GWT's docs has a direct example of clickable buttons. Cheers.
Another option is is overriding the Button's onBrowserEvent() method.

I'm a student and still learning a lot about Java, but I have a pretty good grasp on the basics. Right now I am trying to figure out a way to recreate a radio button to mesh with the UI design for an application I have been commissioned to build.
The entire application is meant to be designed around the Star Trek LCARS interface (Bold bars, distinct color changes, no check boxes or radio buttons). I need to incorporate radio buttons into the design, but I have been unable to find any resource that will allow me to design a radio button without that distinctive filled/empty circle.
I already have a good idea of how I need to work the design. The selected item will change to a different display color with the mouse click or touchscreen tap. Selecting another item in the same group would deselect the original and select the new option, while trying to select the same item would unselect all choices (Select an undisplayed, "default option").
The problem is pure aesthetics, but it is important to the customer.
Is it possible to create a label (or other component) and have the ActionListener "transfer" the user interaction with the object to a radio button? In other words, the user clicks on the selection label and it fires off the same commands (change item/text color, play sound) and also fires off a command to set a designated radio button to either on or off?
well first of all... Everything is possible..its just a matter of how much time/effort you want to put in.
If I read that right..You have suggested creating a hidden radio button that gets information passed to it. This would work but is probably not the best way to design it.
I would personally just make an integer and call it mostRecentLabel or something to that effect and if you have 4 labels you would just keep track of which label was "turned on" with your mostRecentLabel variable. Then just put a function in that responds whenever a label is clicked to update your mostRecentLabel and this would update the display accordingly
