Explanation / Answer

The user will be prompted to enter a different name The Input is :: Willy Shakespeare It is having more than 12 characters. Hence it is satisfied by the loop condition and the input is again asked. The alert will display The name to be printed is EDGAR A. POE The Input is :: ??Edgar A. Poe It is having exactly 12 characters. Hence it is not satisfied by the loop condition and the loop is not executed. Then the alert will display the uppercase of the name entered by the user. use the focus() method to move the cursor out of the textbox We can use the focus to disable the user from entering the text into the textbox. Example:: $('input').onfocus(function(){this.blur()}) function getUserAge(user) ??A function declaration should always start with the keyword 'function' Hence above is the answer. creates a function and stores it in a variable named display_error We are creating the function and using the assign operator to stre the function in that variable. Whenever we try to print the variable,it prints the function on the display.
