Hi, I am interested in knowing how to dynamically modify what browser shows
using javascript. I have seen advert programs that put a javascript at the
end of html code, and then dynamically underline certain keywords that the
browser is showing. How do they do that.
Thanks for your help.

That's a pretty far reaching question. You need to know HTML, the
Document Object Model for browsers and a scripting language such as
JavaScript. Once you know something about these subjects you will need
to write some code and try it out. You can do that right on your own
computer and you don't even need a server to start out.
Open Notepad, copy and paste the code below, save it with a file name
of hi.html. Then go double click on it and see what happens.
Experiment.
<html>
<head>
<title>My Simple Test Page</title>
<script>
function hi()
{
var oWin = window.open();
oWin.document.writeln("<html><head></head><body><h1>Hello,
world</h1></body></html>");
return false;
}
</script>
</head>
<body>
<input type=button onclick='return hi();return' value='Say hi'>
</body>
</html>

Only if you want to write the code yourself. Using DynWrite in the FAQ
there is no need to understand 99% of what you just said.

You don't even need a browser to tinker with JScript.....

Experiment.
And if the user doesn't have Notepad?

Thanks for the tip. I forget that some people still use email for this
kind of thing.:)

I don't know. If I say get a text editor they you'll say, What if they
don't have a computer? After all you can do all this with a pencil and
paper. (But what if he doesn't have a pencil?)
But seriously, I guess I was just trying to encourage the guy to
experiment. My suggestion to you is why don't you give him your ideas
about how to approach the issue. It sounds like you might have some
good ones.

No they don't. This is Usenet so what people use is dedicated newsreader
software (and easily the majority does so).

Not really. You have not trimmed the material unnecessary to maintain
the context of your responses, including Randy's signature (signatures
are never quoted unless they are the direct subject of a response).

Then you need a different stand alone script engine.

No. Your assumption is very flawed. Macs, Linux, any non-windows OS does
not have Notepad. Had you said "Use a text editor", I would have said
nothing about it.
But seriously, I guess I was just trying to encourage the guy to
experiment. My suggestion to you is why don't you give him your ideas

Dynamic modification of a page? Simple. It is so frequently asked that
it is directly answered in this groups FAQ:
<URL: http://jibbering.com/faq/#FAQ4_15>
4.15 How do I modify the current page in a browser?
I assume that you *have* read the FAQ, right?
P.S. You were a long way from properly quoting me.
