I want the text to be printed without commas.

<html>
<head>
<title>Reverse</title>
</head>
<body>
<form name="rev">
Enter the string : <input type="text" name="str"/>
<input type="button" value="click" onclick="rev1()" /><br>
reverse of given string : <input type="text" name="res"/>
</form>
<script type="text/JavaScript">
function rev1(){
var a=rev.str.value;
var b=[];
var i,j=0;
    for(i=a.length-1;i>=0;i--){
    b[j]=a[i];
    j++
}
//rev.res.value=b;
alert(b);
}
</script>
</body>
</html>

If I give the input as abc I am getting an output as c,b,a, but I want it as cba.

    1. You may reverse your string using javascript built-in functions:

              <html>
        <head>
        <title>Reverse</title>
        </head>
        <body>
        <form name="rev">
        Enter the string : <input type="text" name="str"/>
        <input type="button" value="click" onclick="rev1()" /><br>
        reverse of given string : <input type="text" name="res"/>
        </form>
        <script type="text/JavaScript">
            function rev1(){
                var a=rev.str.value;
                var b=a.split("").reverse().join("");
                //rev.res.value=b;
                alert(b);
            }
        </script>
        </body>
        </html>

    2. You may also transfer join your array elements to become a string

              <html>
        <head>
        <title>Reverse</title>
        </head>
        <body>
        <form name="rev">
        Enter the string : <input type="text" name="str"/>
        <input type="button" value="click" onclick="rev1()" /><br>
        reverse of given string : <input type="text" name="res"/>
        </form>
        <script type="text/JavaScript">
            function rev1(){
                var a=rev.str.value;
                var b=[];
                var i,j=0;
                    for(i=a.length-1;i>=0;i--){
                    b[j]=a[i];
                    j++
                }
                //rev.res.value=b;
                alert(b.join(""));
            }
        </script>
        </body>
        </html>
