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 ;-).
