Javascript Array Example - Test for Palindrom


Here are some simple example of javascript. We will try to find if a string is palindrom. A palindrome is a sequence that may be read the same way in either direction - example 1234321 or abcdcba.

Take a look at the following example


<html>
<body>
<script type="text/javascript">
<!--

/*
********************************************************
Example - Test if a string is a palindrom  
********************************************************
*/

var x ="12321"; // string to test for palindrome
var y = x.split('');
var z =[];

var match = true;
for (i=0; i<=(y.length-1); i++)
{
z[i]= y[i];
}

y.reverse();

for (i=0; i<=(y.length-1); i++)
{
if (z[i] != y[i]) match = false;
}

if (match) document.writeln (x + ' is a palindrome');
else document.writeln (x + ' is a not a palindrome');
 //-->
</script>
</body>
</html>
