Answer 1

Can you use the HTML5 attribute pattern? See the MDN article on it for more information.

Using a regex of ^[a-zA-Z][\sa-zA-Z]* seems to cover your requirements.

So something like:

<div>Username:</div>
<input type="text" pattern="^[a-zA-Z][\sa-zA-Z]*" title="Can use upper and lower letters, and spaces but must not start with a space" />

Answer 2

You should try this

 $("#contactname").keypress(function(event){
        var inputValue = event.charCode;
        if(!(inputValue >= 65 && inputValue <= 120) && (inputValue != 32 && inputValue != 0)){
            event.preventDefault();
        }
 });

Answer 3

I finally got solution for this issue

$("#contactname").keypress(function(e) {
       if (e.which === 32 && !this.value.length) {
           e.preventDefault();
       }
       var inputValue = event.charCode;
       if(!(inputValue >= 65 && inputValue <= 120) && (inputValue != 32 && inputValue != 0)){
           event.preventDefault();
       }          
   });

This code working fine for my exact need
