Check if textbox has empty value

Question

I have the following code:

var inp = $(\"#txt\");

if(inp.val() != \"\")
// do something

Is there any other way to check for empty textbox

Answer 1

if ( $("#txt").val().length == 0 )
{
  // do something
}

I had to add in the == to get it to work for me, otherwise it ignored the condition even with empty text input. May help someone.
