What is wrong with the following htmla and javascript code

formToConvert.html

<html>
    <head>
        <title>ExampleToConvert</title>
        <script type = "text/javascript" src = "con.js"></script>
    </head>
    <body> 
        <form id ="myform">
            <input type = "text" id = "field1" value = "Enter text Here"/><br/>
            <input type ="submit" value = "submit" onclick = "convert()"/>
        </form>
    </body> 
</html>

con.js 

function convert() 
{
    var str ;
    str = document.getElementById("field1");
    document.writeln(str.toUpperCase());
}

Why is the above code not giving me the desired result?

    Try:

    str = document.getElementById("field1").value;

    This is because getElementById returns a reference to your HTML Element, not the “text”-value that is contained.
