Prev: how to send XMLHTTP object from a button input
Next: ANUSHKA HOT PICTURES
From: jr on 1 Aug 2010 00:04
I want the AJAX printFromHere() script to fire when the user clicks
the
'print the current page' button.
It doesn't fire now? I don't know if I need another event besides
onClick? This is what I have in the form but it doesn't work.
I would really like it if the xmlhttp response text came back in the
printer response div. I enclose the View Source with the print this
button at the close of this post.
I have enclosed the view source with the javascript function
printFromHere. The button "print this page" input with the call to
the function
is the very last line.

I would also like to know how to get the xmlhttp response to return to
the div id='response_text' below that button input.
thanks,

What is the purpose of xhr in your code? Is it to hold the
XMLHttpRequest object, or to hold the value of field
document.forms[0].search_zonenm.value?

See my earlier response to the original thread about this code for other
issues.

If you can't do that, you are getting way ahead of yourself with Ajax.

Doesn't it?

This is what I'm talking about.

Well, that's good of you.

Why are you using XHTML when IE doesn't support it? Clearly you are
relying on error correction to turn it into HTML. That's not a sound
strategy (despite its inexplicable popularity).

Also, what are you transitioning from? And why are you transitioning
to a language that died on the Web almost a decade ago?

Never do that. Use the - elements - property of the form object.

Object inference. It should be clear from the comments that this is
another form of browser sniffing. Don't write scripts based on
observing a handful of today's browsers, else you'll be rewriting them
in perpetuity (see jQuery, Dojo, YUI, Ext JS, etc.)

Well, this might just be your lucky day as I sure as hell wasn't going
to wade through the whole thing.

What's wrong with that picture? You are clearly just rearranging
patterns here. Where have you seen such a pattern?

I suppose now that the likely suspect has been pointed out, perhaps
some enabler will come along and gift-wrap the answer. I hope not as
this is how library authors are born. :(

That assumption cannot be made from the posting.

Non sequitur.

Since XHTML 1.0 is "a reformulation of HTML 4 in XML 1.0"¹, XHTML 1.0
Transitional (instead of Strict) needs to be declared if one wants to
declare and use XHTML, and use features that were (prematurely) deprecated
by HTML 4.01, such as the `target' attribute and the `iframe' element.

I wished people would stop perpetuating this legend. That many people do
not know how to use XHTML properly or do not know about the advantages that
XHTML can provide does not make the language dead.²

LOL. You really think this "jr" guy is using XML parse mode?
Furthermore, on the entire Web, I know of exactly one document that
creates an XHTML DOM. My XHTML Build Test page.

Again, what would be the point as IE (< 9) anyway does not support
it. It's been a dead issue almost from the start on the Web.

Not only that, but you are flat-out wrong about the context of this
posting. The posted markup is not going to work in XML parse mode.

Non-sense.

No kidding. But see above.

And how many sites on the Web do you know of that use XML parse mode?

It's a stiff. Bereft of life, it rests in peace. :)
