How can I detect onclick() or similar for individual characters in a text?

Question

I\'m new to Javascript and would like to modify a text string by clicking on individual characters. The string is: 0000 0000 0000 0000 representing a binary num

Answer 1

Put each 0 into a span and register an eventhandler on the whole paragraph, in order to use delegation. Use Event.target property to change the text of the span you clicked on in the event handler.
