Mar 24.2007

[CODE]function changeSize()
{
var newSize = prompt(“Please enter size between 10 and 20″);
if (newSize => 10 && newSize <= 20)
{
document.body.style.fontSize = newSize;
}
else
{
return false;
}
}

<input type=”button” value=”Enter Size” name=”size” onclick=”changeSize()” />[/CODE]

its supposed to change the documents font size using a prompt – as long as the input is between 10 and 20. but im getting error “object expected”

@BuilderQMar 25.2007 — [CODE]newSize => 10[/CODE] should be [CODE]newSize >= 10[/CODE] Also, unless you append a unit onto the inputted font size, it will only work in Internet Explorer.

@mr_newbieauthorMar 25.2007 — thanks, it works now.

Also, unless you append a unit onto the inputted font size, it will only work in Internet Explorer.[/QUOTE]

what units are there for fontSize? and how would i include it to the function?
Copy linkTweet thisAlerts:
@BuilderQMar 25.2007 — Font size can be defined used the standard CSS units (px, pt, em...), and can be set like so: [CODE]document.body.style.fontSize = newSize+'px';[/CODE]

Success!
