AJAX - Comment Box with [ Javascript jQuery JSON PHP MySQL ] - Step by Step How to Guide - Part 18

In this last and final tutorial of this series, I talk about making sure that when a new comment is inserted to the list, then the user cannot immediately delete the same comment which they have made, due to the fact that we havent set an event handler on newly inserted objects.

When we first loaded the page, we looped through all delete-btn's and attach an event handler. Therefore the only thing which we need to do once we have inserted a new comment into the list, is to run the same loop once again, to reattach new event handlers.

So we basically take the code which we wrote before and place it into a function so as we then dont have to rewrite the same code.

Finally I then talk about how to only allow the user which has entered the comment be able to delete it. As you know at the beginning we made 2 input elements of type hidden holding the userId and userName. We use this information to act as the cookie which would be stored on the client when the user has logged in.

Once this has been done, all works just fine.

Hey David, thank you so much for your tutorial! The way you explained it was perfect! There are 3 things what you could add to this tutorial:

1. a reply function for a comment 
2. an edit function with the date when it was edited
3. rating function for a comment sothat rated comments will be listed on top.

[mishalalsharekh]

Thanks a lot, I really liked this tutorial series, especially your way to taking care of client script first before server side also with good code housekeeping . Looking forward to learn more from you.

I wish you make a tutorial to how to use bootstrap with jquery.

[kevinpatel]

[TheGoldDandelion]

You've saved my life! ^^thank you! you're a great teacher ^^

[cherrymontesa]

Yes I agree with omar. Please make login/signup tutorials with cookies especially if it's actually needed for this comment box tutorial. Otherwise, it's like a waste of time for beginners because we can't make them ourselves and we won't be able to make use of this comment tutorial... Nobody's rushing you to finish all these tutorials in one day so you could take your time and add the necessary stuff we need to know

Other than that very nice tutorial, it took me hours to finish them all and almost got me crazy trying to find out why it wasn't working near the end but I made it work. Thanks a lot!

[GaiaKH]

Thanks for this tutorial ! was kind of hard in the middle but eventually it worked perfectly !

[samhaas]

Thanks David for you r invaluable videos. I will become a coder before long. ...like your accent (coming from a yank).
