How to disable/remove only first space on input field?

Question

Good morning everybody!

I have a case, when I should prevent users to entering space as a first character on input field.

I have a demo here: http://jsbin.com/fo

You can do this by checking if key is space and selection start is 0 as below:

$(function() {
  $('body').on('keydown', '#test', function(e) {
    console.log(this.value);
    if (e.which === 32 &&  e.target.selectionStart === 0) {
      return false;
    }  
  });
});
