The Message Box

This is a very simple script. It opens up an alert message box which displays whatever is typed in the form box. Take a few minutes to learn as much as you can from this, then we'll break it down into smaller pieces.

<HTML>

<HEAD>
    <SCRIPT LANGUAGE="JavaScript">
        <!-- Beginning of JavaScript -

        function MsgBox(textstring) {
            alert(textstring)
        }

        // - End of JavaScript - -->
    </SCRIPT>

</HEAD>

<BODY>
    <FORM>
        <INPUT NAME="text1" TYPE=Text>
        <INPUT NAME="submit" TYPE=Button VALUE="Show Me" onClick="MsgBox(form.text1.value)">
    </FORM>

</BODY>

</HTML>
