unwanted dialog appears when pressing enter key

I am developing an online radio project. In the middle of hearing music, if the user presses the enter key开发者_开发问答, sometimes a dialog is displayed. What is the remedy for this?

Do this:

protected void onSavePrompt()
{
   return true;
}

 protected void onClose()
    {
       return true;
    }

add the code in ur screen where the issue arises. One method is for closing and one for saving.

depending on your requirement u can add both or any Hope this helps.
