Is it possible to pass parameters to prototypes? Such as...
var myString="Hello World!";
This would be a case of passing a value of red to the prototype script to display the text as red. Something like this?
This example doesn't work, but I'd like to know how to do it, if it's possible.

yeah, there's absolutely no difference between a prototyped property/method and any other property/method.

The String object already has a built-in methods for formatting text:
big, blink, bold, fixed, fontcolor, fontsize, italics, small, strike, sub and sup.
myString = new String("Formatting methods")
document.write ("<p>big() = " + myString.big())
document.write ("<br>blink() = " + myString.blink())
document.write ("<br>bold() = " + myString.bold())
document.write ("<br>fixed() = " + myString.fixed())
document.write ("<br>fontcolor("5") = " + myString.fontsize("5"))
document.write ("<br>small() = " + myString.small())
document.write ("<br>strike() = " + myString.strike())
document.write ("<br>sub() = " + myString.sub())
document.write ("<br>sup() = " + myString.sup())

Glenn, I'm aware of those styles... actually, I want to create custom ones based on the same ideas as those. I just need to know how to do it.
String.prototype.color=function(theColor) doesn't seem to work... or maybe it's just me... would this work?
... or am I missing something...

1) doesn't return anything, because this.style.color = somecolor, does not return a value.
2) this.style.color does not exist; Stings don't have style properties.

I appreciate the help, but you're simply confirming what I already know... this script doesn't work.
The next step is... how can I make it work?

return '<span style="color:'+theColor+'">'+this+'</span>';
i've used span tag instead of the font tag which i believe is deprecated in XHTML.
but if you still want to use font tag:
return '<font color="'+theColor+'">'+this+'</font>';

By defining custom methods for the String and Array prototypes (and window too) to implement whatever HTML tags/attributes/containers I want.
See my HTML() bookmarklet library (http://www.angelfire.com/ca/redwards/html__.calendar.html) for details.
