14. FTMSK UiTM Pahang  Page 14 Form Processing  An HTML form with common elements and buttons -3 types of buttons -Submit : to allow data in the form to be submitted into the database or to another page -Reset : to clear all data in the form/to reset the form -Button : user-defined action. Programmer writes a code to trigger specific action once the button is clicked Adding HTML Input Fields

15. FTMSK UiTM Pahang  Page 15 Form Processing  How to process inputs from HTML form? -Make sure you have created a complete HTML form (plus with input fields and a button) -We have two ways to process the inputs: -Client-side Scripting -The best example is using JavaScript (which you will learn in the next lesson) -JavaScript able to do input validation, display the outputs, process the inputs like doing calculation, and so on -BUT, JavaScript cannot send the inputs to the database! -Server-side Scripting -You will learn to process the inputs using Active Server Page (ASP) -It is able to do what JavaScript can do -It can send the inputs to the database! Passing a form as a parameter

16. FTMSK UiTM Pahang  Page 16 Form Processing  How to process inputs from HTML form? -You need to complete JavaScript lesson first before you can start to code how to process the inputs -BUT, I suggest you to learn by yourself first, we have sample in the text book and on the Internet -Some examples: -Example 1Example 1 -Example 2Example 2 Passing a form as a parameter
