Hi friend,
We test and run the program having error of it always come in the "else"
condition due to white space problem.
This problem remove to use trim function in javascript.
function trim(value) {
var temp = value;
var obj = /^(\s*)([\W\w]*)(\b\s*$)/;
if (obj.test(temp)) { temp = temp.replace(obj, '$2'); }
var obj = / /g;
while (temp.match(obj)) { temp = temp.replace(obj, " "); }
return temp;
}
correct code :
<html>
<head>
<title>javscsript program</title>
<script type="text/javascript" language="javascript">
function trim(value) {
var temp = value;
var obj = /^(\s*)([\W\w]*)(\b\s*$)/;
if (obj.test(temp)) { temp = temp.replace(obj, '$2'); }
var obj = / /g;
while (temp.match(obj)) { temp = temp.replace(obj, " "); }
return temp;
}
function palindrome()
{
var string=document.f.text.value;
document.f.reverse.value=reverse(string);
alert(string);
alert(reverse(string));
if(trim(string) == trim(reverse(string)))
{
alert("this is djfksjfja palindrome");
}
else
{
alert("this is not a palindrome");
}
}
function reverse(ss)
{
var len=ss.length;
var rev=" ";
for(var i=len; i>=0; i--)
{
var rev= rev+ss.charAt(i);
}
return rev;
}
</script>
</head>
<body>
<form name="f">
Enter string to be Reversed : <input type="text" name="text"><br>
<input type="button" onClick="palindrome(); " value="submit "><br>
Reversed String is : <input type="text" name="reverse">
</form>
</body>
</html>
If you have any more problem then explain in details.
Thanks
