Using jQuery to Reorder a List and Update a Database

by

This tutorial will show you how to use jQuery to allow as list (UL) to be reordered and will also make an AJAX call to a PHP file that will update the database when an item is dropped. I found this useful for a project I was working on recently. The user wanted to be able to change the order that categories displayed in a report. The items are stored in a database with a field called display_order. When the report is generated we simply order by that field.

Password Verification and Strength Checker

This tutorial will walk you through creating a registration form that includes a password strength checker to tell the user how strong (security wise) their password is. This form will also include two password boxes and will verify that the same password has been entered twice to prevent typing the wrong thing into a password box.

Hide and Show a Div Using Javascript

by

This tutorial will show you how to create a hidden Div and display it with the click of a link. There are a few reasons you may want to hide a Div in a website design. You may want to create a drop down type menu or a box that will show more information when you click a link. Another reason would be for SEO purposes. In theory hiding information in a Div is not against Google’s rules. As long as the user can still see the content when clicking a button you are not displaying different information to the user than you are to the search engine.
