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

Answer 1

This jQuery function selects all the text inputs when a key is unpressed, removes all whitespace from the beginning of the string and replaces the value of the input:

I do not recommend to use trim() when blank spaces are replaced directly with keyup() because when you type a space after a word, it will be deleted before you start writing the next word.
