dojo - programmatic way to show invalid message

Question

dojo newbie - giving it a shot. After submitting a form, If an error is returned from the server I would like to show that message on the dijit.form.ValidationTextBox

var user_email = dijit.byId("login_user_email");
user_email.set("invalidMessage", data["result"]["user_email"]);
//need to force show the tooltip but how???

Any help much appreciated.

Answer 1

See it in action at jsFiddle.

1. Just show tooltip:

   var textBox = bijit.byId("validationTextBox");
   dijit.showTooltip(
       textBox.get("invalidMessage"), 
       textBox.domNode, 
       textBox.get("tooltipPosition"),
       !textBox.isLeftToRight()
   );
   

2. Temporarily switch textBox validator, force validation, restore the original validator:

   var originalValidator = textBox.validator;
   textBox.validator = function() {return false;}
   textBox.validate();  
   textBox.validator = originalValidator;
   

Or do both at once.

I think you can show the tooltip via myVTB.displayMessage('this is coming from back end validation'); method
