Random number are number which make
a random sequence of numbers.In many appliaction we need random number
sequence,for example creating roll number between 1 to 10, in java script you can get random number using Math.random()
which return a floating point number less than zero.
You can get number within a range by multiplying. If you want
integer number then use can use parseInt function..
Create Random Number Between 1 to 10
function ranNumber()
{
alert(parseInt(Math.random()*10));
}
HTML..
<body>
<input type="button" value="Get Random Number" onclick="ranNumber()" />
</body>
Change Text Color Randomly ..
function ChangeTextColor()
{
var ob=document.getElementById('s3');
ob.style.color='#'+parseInt(Math.random()*10)+''+parseInt(Math.random()*10)+''+parseInt(Math.random()*10)+''+parseInt(Math.random()*10)+''+parseInt(Math.random()*10)+''+parseInt(Math.random()*10);
setTimeout("fun2()",1000);
}
HTML...
<body onload= "ChangeTextColor()">
<span id="s1"></span>
</body>
Change Text Color..
function ChangeTextSize()
{
var ob=document.getElementById('s1');
ob.style.fontSize=parseInt(Math.random()*100)+'px';
setTimeout("ani()",1000);
}
HTML...
<body onload= "ChangeTextSize()">
<span id="s1"></span>
</body>
Move A Divison Randomly
function movedivison()
{
var ob=document.getElementById('d1');
ob.style.top=parseInt(Math.random()*800);
ob.style.left=parseInt(Math.random()*800);
setTimeout("movedivison()",1000);
}
HTML...
<body onload= "ChangeTextSize()">
<div id=d1 style="height:100px;width:100px;position:absolute;background-color:Aqua">
</div>
