    Default Help with validating a string

    Guys.

    My first java post, and my first attempt at trying to modify a java script.
    I have a small script that i'm trying to modify (below)
    This was originally to check if a field was empty or not, however, I'd like to modify it so it checks the
    existance of a specific string.

    I've played with the X== section, but i've now conceded that it's not as easy as i thought it would be.
    Ideally, i just want to create a challenge question, and the script will check if the answer is correct.

    Could anyone point me in the right direction please.




    <script>
    function validateForm()
    {
    var x=document.forms["myForm"]["answer"].value;
    if (x==null || x=="")
    {
    alert("Answer must be filled out");
    return false;
    }
    }
    </script>
    </head>


    <body>
    <form name="myForm" action="demo_form.asp" onsubmit="return validateForm()" method="post">
    Answer: <input type="text" name="answer">
    <input type="submit" value="Submit">
    </form>

    Java != javascript! Go and find a javascript forum.

    Try this javascript forum: JavaScript frameworks - CodingForums.com
    Or learn JAVA - not javascript / html
