Jquery Check if Array contains empty entry

Question

I have an array : var list = ["",""];that will be filled with strings.

Before I let the user do something, I would like to make sure the array doesn't contain anymore empty entry.

I made a special function that I would like to work like that:

function checkEmptryEntry(array_name)
{
   if(arrayContainsEmptyEntry(array_name))
   {
      return "bad";
   }

   else
   {
      return "good";
   }
}

How could I do that ?

What have you tried so far? Iterate through the array and check for at least one empty string, and please return a boolean. — Andrew Li

Assuming you have used jquery, you can use inArray:

return (!jQuery.inArray("", array_name) ? "good" : "bad");

Using native javascript, You can use indexOf to find first position of empty string. if it return -1, then array have no empty string:

return (array_name.indexOf("") == -1 ? "good" : "bad" ) ;
