Change the text in a TextBox on button click in JavaFX

Question

I have this easy little form in my JavaFX application. I want to use a button to change firstNameText and firstNameText .

I'm not capable, I'm a newbie. I tried the code below, where is my mistake?

def lastNameLabel = Label { text: "Last Name" };
def firstNameLabel = Label { text: "First Name" };
var lastNameText = TextBox { text: "Last Name" };
var firstNameText = TextBox { text: "First Name" };

def cancelButton = Button { 
    text: "Cancel" 
    action: function() {
        lastNameText = TextBox { text: "ciao" };
        firstNameText = TextBox { text: "ciao" };

    }

};

Answer 1

you are creating 2 new textboxes instead of updating your 2 existing ones.

try

action: function() {
    lastNameText.text = "ciao";
    firstNameText.text = "ciao";
}
