Where to find a code for responseHTML

Dear Expert,

Do you know where I can find the function or javascript library  of responseHTML in other webiste ?
so I can access it through DOM to extract data in other HTML file like
 document.getElementById('test').innerHTML =xmlhttp.responseHTML.getElementByID("......)
that is similar to  extract xml data from xmlhttp.responseXML

I got one but not complete at http://www.ohjelmointirengas.fi/Ohjelmointi/responseHTML.txt

Please help and advise

all you are doing above is creating a mootools Request object everytime you run "main()".  nothing happens because you're not asking it to do anything.  you need to tell the request to send()
function main() {
myRequest = new Request({
			url: "http://www.e-hftrade.com/mootools/screen_update/sales1.htm",
			noCache: true,
			link: 'ignore',
			method: 'get',
			async: false,
			onSuccess: function(responseText, responseXML) {
				$('my_content').innerHTML = responseText;
				alert($('my_content').getElementsById('Book1_25322').getElementsBYTagName('img').src);
			}
		}).send();
}

I've used mootools but JQuery will do the same for you.  the following is the ajax request object using the mootools library.  When the data has been received you can see I load an htm page and then access elements within it using simple css selectors.


		myRequest = new Request({
			url: "sales1.htm",
			noCache: true,
			link: 'ignore',
			method: 'get',
			async: false,
			onSuccess: function(responseText, responseXML) {
				$('my_content').innerHTML = responseText;
				alert($('my_content').getElement('#Book1_25322').getElement('img').src);
			}
		});

However you will not be able to ajax to another website unless for IE it is in trusted sites and for Fx it implements Cross Origin Resource Sharing

That's right, the html file has to reside in the same domain unless you want to use the additional Request.JSONP package from mootools
see: http://www.clientcide.com/wiki/cnet-libraries/06-request/00-jsonp

Btw You've answered this question in your other question you have open: http://www.experts-exchange.com/Programming/Languages/Scripting/JavaScript/Q_26622228.html?cid=1749

that is the right code.  I would focus on using the Request.HTML and the onSuccess function() to obtain the responseHTML content

Dear Taqit,

it is not wokring and no response for my following try , and your index.html
in other  thread is working for sales1.htm so I put this following code  file in the same directory
under screen_update

And I want to know which word in your is code  calling mootools libray , OnSucess, Right ?
And  I found some ajax example   is working if I put the code file at D: drive
and some is not like yours.   Actually, xmlhttp is internet stuff, so it cannot access file system
on PC, RIght? But I don't know why some ajax example is also working on D: drive.

RobOwner (Aidellio)Commented:
the "Request" is part of mootools.  without mootools you would have to determine which ajax object to use... see here:
http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_first

the onSuccess is an Event that happens when the Request is completed and receives data back

AJAX = Asynchronous JavaScript and XML.

AJAX is not a new programming language, but a new way to use existing standards.

AJAX is the art of exchanging data with a server, and update parts of a web page - without reloading the whole page.


Of course it will work with D: but as long as you are running it through a local webserver like http://localhost
