JavaScript and HTML assignment

Question

Okay, I'm ashamed to be asking, but it just isn't clicking. My brother-in-law has an assignment to have a text box and then a command button. When the button is pressed, it will loop 10 times printing whatever was in the text box. Should be simple - I know!

I know the error is on this line:

<input type="button" value="Press Here" onClick="sayit(document.getElementById('myTextField').value) ">

Here's what we have:

<html>
<head>
<title> Homework #11 part 2 </title>
<script type="text/javascript">
function sayIt(var message){

        count = 1;
        num = 10;
        while (count <= num) {
        document.write(message);    
            document.write("<br/>");

            count = count + 1;
        }


}
</script>
</head>
<body>
<p>
Type in a phrase.
<input type='text' id='myText' />


<br />
<input type="button" value="Press Here" onClick="sayit(document.getElementById('myTextField').value) ">

</p>
</body>

<html> <head> <title> Homework #11 part 2 </title> <script type="text/javascript"> function sayIt(var message){ count = 1; num = 10; while (count <= num) { document.write(message); document.write("<br/>"); count = count + 1; } } </script> </head> <body> <p> Type in a phrase. <input type='text' id='myText' /> <br /> <input type="button" value="Press Here" onClick="sayit(document.getElementById('myTextField').value) "> </p> </body> </html> — Patrick From An IBank

use a for loop for that if its for school... for (i=0; i < 10; i++){document.write(message)} — clamchoda

The code has three thins wrong.

1) function sayIt(var message) should be function sayIt(message) 2)onClick="sayit(....)" should be onClick="sayIt(....)"

sayIt is function name

3)document.getElementById('myTextField').value should be document.getElementById('myText')

myText is input element's id attribute

You've got three things wrong.

^{_{^{_{Hints - you don't need var in your function declaration, your id is not right, and you "misspelled" sayIt}}}}

( ^ If you care to see the answers, they are above ^ )

Invest in Firebug. It gave me all the answers I needed. ;)
