Dont worry we dont need to find out any bug in this code.. Its working perfectly.:-P
My boss came to me and said "Hey just tell me whats the best of way of writing code for
a dynamic HTML table (add row, delete row, update row).No need to add any CSS. Just javascript. No Jquery library etc. I was confused that in the middle of the project why he asking for some stupid exercise like this. What ever i wrote the following code and mailed him and after 15 mins i got
a mail from him. "
I was expecting much better code from
a guy like you. Anyways good job
monkey.(And with
a picture of
monkey as attachment.)
thats was the mail. Line by line.
I want to reply him but before that i want to know about the quality of my code. Is this really shitty...!!! Or he was just making fun of mine.
I dont think that code is really shitty. Still correct me if you can.Code is working perfectly fine. Just copy paste it in
a HTML file.
