Check email availability using jQuery’s ajax (Part 2. easy way)

On our previous tutorial (Part 1), we have deal with hard way of checking email availability using jQuery ajax.
Now we will accomplish the same problem, which is to check email availability without have to reload the page (server side processing).

Remote feature allow us to process ajax call then handle its response.
Well then, lets begin.

Here we will make a form such as registration form, which is contain of email field, that need to be checked for its availability.

Naturally, we will check its (email) availability by let the form submitted once, then processed it in the server. However by using AJAX, we can make it possible to check its availability on client-side. Again, jQuery will make it much easier to accomplish.

Generate dynamic chart using amchart and php + ajax drill down

On our previous tutorial, we’ve made simple dynamic chart using php. Now we will add little feature to make the chart more interactive. We will add drill down feature using jquery’s ajax.

For this purpose, we need to make several changes. We will add another chart as a view of dill down data. Again, we will simulate this data using -fake-data dummy.

We can assume our chart can show the detail of composition of the visitor for ‘clicked’ day, eg. for January 1st, the number of visitor is 68 persons, we -hope- can see the composition of that ‘68′ persons divided into male and female.

Enough for introduction. Lets coding.

Pengalaman dari PKL (agustus 07),
Saya dihadapkan pada kasus reverse engineering dari sistem informasi yang sudah ada, namun tidak bekerja.
Sistem tersebut dikembangkan berbasis web php. Bisnis proses dari sistem tersebut pada awalnya sangat tidak jelas, karena yang mereka berikan pada saya adalah puluhan file .php dengan susunan dan sistem penamaan yang tidak teratur seperti a1.php, a2. php, h1.php, dll.
Bagi programmer seperti saya, hal tersebut sangat membingunkan, pertama karena sistem tidak jalan, dan kedua kode program tidak memiliki aturan jelas.
