Nullyfing events in a HTML

[c.anandkumar]

Hi All -

I am trying to do the following,
1. Get a piece of HTML from a db
2. Display it on my page
with a requirement - clicking on any links in that HTML should not take
me away from the page.

This does not only include links which are formed by <a>nchor tags, but
also other ways of doing it, like,
<span onClick='location.href="http://someurl"'> Blah blah..
</span>

In other words, all the events that can be raised by this piece of html
should be blocked.

Setting all the 'onClick's and 'href's to "#" or blank string is
probably a good idea to start with, but the list of all such possible
causes for an event to be raised, may not be very straightforward to
compile.

I was wondering if there could be any way to nullify/block the events
that can be raised by such a piece of HTML.

Thanks for your input

have you considered doing it serverside?

have you considered doing it serverside?

You mean setting the href targets to blank values? Yeah, I did, but
even in that case, I will have to find out that part of the HTML which
is active. By active, I mean that HTML which is a hyperlink or a div
with a onMouseMove attribute attached to it or anything. Finding out
all such pieces will require a lot of work. Could there be a simpler
way?

No i mean parsing the page with a serverside script such as with php or
perl. there 'seems' to be a lot more you can do with these.

Your looking at doing it from DOM? I would have thoought it would have been
easier parsing it as text then all you have to do is seek out "href" then
replace anything in quotes after that with #
Just my twopenneth worth.

I use "The Proxomitron" for that purpose, although, sadly, it is not being
supported anymore, due to the passing away of its creator.

Just in case, here's the link:

The filter can be configured in a very colorful variety for all tastes...

For FF and Co you can use addEventListener('event',true) to capture
events from the top.

For IE5.5 and higher you can use setCapture() method:

It will not prevent key events, but mouse events will be killed.
