[Solution] jQuery: How to capture the TAB keypress within a Textbox

Problem : 

• I have a text box which is an ajax auto complete,so when i select a record i save an id into         a hidden variable.
•  And there is a keydown event on that text box, if key down i delete the hidden variable             value.  because i don't want the user to enter any thing after he selects from the  autocomplete.
• Now even when i press the tab button the hidden variable is cleared. 
• Is there a way to avoid only Tab press event.?

Answer :

• When the tab is pressed you have to read if the keydown was from the Tab button, if so you can avoid it..

$("body").on('keydown', '#textboxId', function(e) { 
  var keyCode = e.keyCode || e.which; 

  if (keyCode == 9) { 
    e.preventDefault(); 
    //IF Tab Pressed You Can Do Anything Here
  } else{ //If Its Not Tab, You Can Do It Here }
});
