Question

I know this question is so noob. but I want to know how to get the first letter of the entered word in the input text.

I do not know about that. but please tell me about it.

Answer 1

The built-in Javascript substr() method can do this:

 var firstChar = $('#textbox').val().substr(0, 1); 

The first argument is the position of the character to begin with, the second is the length.

Answer 2

You can use charAt to get the first letter.

 var x = 'some text'; alert(x.charAt(0)); 

If you use jQuery and have a text field with id = "firstName", you can access the first letter as follows.

 var firstLetter = $("#firstName").val().charAt(0); 

Answer 3

Try

 var value =$('#input').val(); var firstLetter=value.substring(1, value.length);
