Re: two questions

I have read the following message from "Darius Fatakia"
<darius_fatakia @yahoo.com>
and have decided to lend my vast knowledge.

The writer said:[color=blue]

and my reply is:
document.myform .description.va lue = description[i]; should be
document.myform .description.va lue = title[i];

For the color look for info on CSS.

I don't understand the slash before the > and if title[i] =~ unless
that is something in xml which is beyond my knowledge.

To change the color, you script .color whereas you script
..backgroundCol or to change the background color.

I know just above zero about XML. So, I could be totally
wrong here, but I hope not.

I'll expand a little on earlier comments.

// I don't think you want to split a string across an input line.
// I assume this was a posting thing.
var title = new Array(
"Death in Venice",
"A portrait of the artist as a young man",
"A room with a view",
"The house of spirits",
"Of love and shadows");

// I like putting {} on separate lines to verify that they
// are aligned correctly. Other people like other styles, I
// know, but I needed to sort out what was happening.
for(i = 0; i < title.length; i++)
{
// != means not equal
// == means equal
// = is always a assignment statement even in an if test
// Don't know what the leading slash is for
// nor the trailing (There are some langages were you have
// indicate that variables are a string in comparisions, but
// JavaScript isn't one of those.)

// In a production environment, you want to consider
// space normalization: eliminate leading, trailing, and
// multiple blanks.

if (title[i] == document.myform .title.value)
{
// I don't see the description arrary declared.
document.myform .description.va lue = description[i];
found = 1;
break;
}
}

I think you are confusing a tag end marking such as </tr> with a field
end marking >.

Questionable:
</tr>
<tr><td><img src="spacer.gif " height="20" alt="s3" />

Try:
</tr>
<tr><td><img src="spacer.gif " height="20" alt="s3">
