    • ]]>     To using prototype, first we must download it. It’s only 1 file named ‘prototype.js‘. It is about 120kb, a bit too large for a website. but don’t worry, because the 120kb will do more… ;) besides that, we can compress it using any packer. I won’t describe how to compress the file here. If you wanna compress the file, you can learn it on “Compressing JavaScript”.

    To use the prototype, first refer to the ‘prototype.js’ as shown below
    <script type="text/javascript" src="prototype.js">
    </script>

    Place it at the <head> tags of your html. Actually you can place it anywhere to use prototype, but It always be good to place it on the head because your pages will look cleaner.

    And the main function in prototype is

    document.observe('dom:loaded' , function() {
    ... -> script code here
    });

    it’s not necessary to include the function if we want to use prototype, but this function guarantee that all the DOM structure has been loaded before the script run. That is a good habid to always use this function.

    The Hello World

    It’s a good idea to start every programming with the ‘hello world’.

    document.observe('dom:loaded' , function() {
    $(document).update("Hello World!!");
    });

    note that we call the sexy function ‘$(document).update‘ to pop out the text. about further of this function, we will learn it together later… by now, this is only ‘Using Prototype‘

  • The Prototype $() function
  • The Form $F() function
    • ]]>     The dollar dollar function is Prototype’s CSS Selector Engine. The ‘$$()’ function returns all css match elements. It was used quite same as the CSS selector. For example, to get all tags with the class “myclass”, we use the following:

    $$(".myclass")

    This function will return the array of elements match the selector string. And We can make the returned elements bold like this:

    $$(".myclass").invoke('setStyle', { fontWeight: bold; })

    Easy as pie…

    • ]]>     The dollar function is one of the Prototype Utility Function. $() is the most frequently used prototype’s function. basically it was used to refer an element in the HTML page. The function is quickly shorthand for getElementById.

    The usual function identifying an element is:
    document.getElementById("element_id")

    The $() function reduces the code to:
    $("element_id")

    For example, you can set the CSS text color with this code:
    $("element_id").style.color = "#ffffff";

    Or, the “Prototype way”:
    $("id_of_element").setStyle({color: '#ffffff'});

It used by many giant-website such : Apple, Gucci, etc… The Prototype JavaScript Framework is a JavaScript framework created by Sam Stephenson. Prorotype is implemented as a single file of JavaScript code “prototype.js”.

    Prototype is also used as the low layer for many framework, for example: script.aculo.us, Rico, ExtJS, Moo.fx, etc. Prototype provides many functions for developing JavaScript web applications. The prorotype features programming shortcuts for accessing element, events, and major functions to deal with Ajax.

    Prototype also feature library functions to support object oriented programming that use classes and ojects, something the JavaScript language hard to implement.

    You can find and download prototype on their site.
