Well optional argument is essential feature when it comes to re usability of your code. But its not given in js as simple as its given in PHP & other languages. But with some simple trick you can also achieve the same.

For e.g.

function calCulate(val1, val2, operator){
if(!operator){
operator = 'plus';
}

switch(operator){
case 'plus':
return val1 + val2;
break;

case 'minus':
return val1 - val2;
break;
}

}

alert(calCulate(1,2));

alert(calCulate(2,1,'minus'));

this is it and now you have optional argument in your Javascript code

basically this is the most simplest way to load data in twitter way (Load more). for this i have not used jquery, mootools or any other fancy javascript framework. to use this you need very basic knowledge of javascript along with little ajax & php that’s it, so here we start

step 1: you html base

again i have kept this very simple.. just one div where you want to show your twitts. now heart of this code will be your javascript functions here we will use 2 javascript functions one to send request (AJAX) and another one to load your resulting twitts… also i have used 1 javascript variables to trace my twitts (pages)

i.e.

var page = 1;

lets start with first function

function getData(){

	document.getElementById("div-Loading").className = "show";

	document.getElementById("div-button").className = "hide";

and this are simple Stylesheet classes to show and hide the content. Read more…
