Crash course on Javascript Loops
Loops in Javascript by RockBll4
First of all this is my second first article, so dont be too harsh.
Well I know some Javascript and I thought I'd do a little article on Loops.
So the loops in javascript are: the for loop and the while loop.
THE FOR LOOP:
The for loop is used when you know in advance how many times the script should run.
the syntax for the for loops is as follow:
for ( var = value; var <= endvalue; var(increment) )
{
code to be executed within the code block
}
Example:
<html>
<head>Javascript for Loop Example</head>
<body>
<script type="text/javascript" language="Javascript">
<!--
var i = 1;
for ( i = 1; i <= 5; i++ )
{
docu<i></i>ment.write("Hi " + i + " times");
docu<i></i>ment.write("<br/>");
}
//-->
</script>
</body>
</html>
Result:
Hi 1 times
Hi 2 times
Hi 3 times
Hi 4 times
Hi 5 times
THE WHILE LOOP:
The while loop is used when you want the loop to execute and continue executing while the specified condition is true.
the syntax for the while loop is:
while ( var <= endvalue)
{
Code to be executed within the code block
var(increment);
}
Example:
<html>
<head>Javascript while Loop Example</head>
<body>
<script type="text/javascript" language="Javascript">
<!--
var i = 1;
while ( i <= 5 )
{
docu<i></i>ment.write("Hello " + i + " times.");
docu<i></i>ment.write("<br/>");
i++
}
//-->
</script>
</body>
</html>
Result:
Hello 1 times.
Hello 2 times.
Hello 3 times.
Hello 4 times.
Hello 5 times.
There is your crash course on the loops in Javascript.
If you would like to further your understanding on loops or Javascript go to google and do some research ;-).
