I did not try to work with the page that you gave yesterday, but what I gave is a solution (might be) that fits on the subject given. Since you will be submitting form without clicking on the submit button, then, all you have to do is determine the length of characters inputted by the user, if in case, that the length of the input is equal to five, then, you have to execute a command (function).

I suggest you make use of onkeypress function for the textbox. If the total number of characters in the textbox reaches a minimun lenght, then execute a function. http://www.w3schools.com/jsref/event_onkeypress.asp
