Using JavaScript controls

You can create JavaScript objects that contain the state and implement the behavior of a control. The controls take care of drawing themselves, including changing their appearance as a result of various state changes.

To create JavaScript controls

Create JavaScript to add screen controls. The following example adds a text box and a button.

var helloButton;
+var nameField;
+
+...
+    // Add a text box to the view
+    nameField = new TextField(null, "Enter your name");
+    mainView.addControl(nameField);
+    
+    // Add a button to the view
+    helloButton = new FormButton(null, "Say Hello!");
+    helloButton.addEventListener("ActionPerformed", helloButtonClicked);
+    mainView.addControl(helloButton);
