1) In the code above, you only set the value of the variable maxLength. 
To set the length of an element, you have to do something like:

document.myForm.myInput.maxlength = 5;

2) Do not use the onfocus eventhandler for this, because it's possible to change the checkbox without the onfocus-handler being called for a second time.
