Ajax without xmlhttp

[balakrishnan.dinesh]

Is Ajax can only used as xmlhttp or else it can use for
anyother purpose,
If any sample example code for that, plz reply to me soon.

Thanks

XMLHttpRequest is /how/ Ajax is usually achieved, it isn't the purpose
of the technique.

Alternatives include frames, iframes, and passing data through the
query strings of images.

Her is a simple AJAX Tutorial: http://www.w3schools.com/ajax/

You may want to ad support for IE when using the XMLHttpRequest Object:

function GetXmlHttpObjec t(handler)
{
var objXMLHttp=null
// Firefox, Opera 8.0+, Safari
if (window.XMLHttp Request)
{
objXMLHttp=new XMLHttpRequest( )
}
// Internet Explorer
else if (window.ActiveX Object)
{
objXMLHttp=new ActiveXObject(" Microsoft.XMLHT TP")
}
return objXMLHttp
}

You don't have to use xml to pass data back and forth if that was your
question but otherwise xmlhttp IS Ajax. Another page linked to the w3
tutorials, I'll link you to mine since it shows how to pass data with
iframes in addition to ajax. (warning: self promoting link)

Someone might want to tell w3schools to test the code in IE7.

function GetXmlHttpObjec t(handler)
{
var objXMLHttp=null
// Firefox, Opera 8.0+, Safari

And IE7

if (window.XMLHttp Request)
{
objXMLHttp=new XMLHttpRequest( )
}
// Internet Explorer

IE version 6 and prior.

else if (window.ActiveX Object)
{
objXMLHttp=new ActiveXObject(" Microsoft.XMLHT TP")

And if the IE browser doesn't use/have Microsoft.XMLHT TP? Another reason
I find the level of script tutoring at w3schools to be questionable at best.

And dynamically loading .js files :)

Yes, IE7 XMLHttpRequest may and are probably implemented diffrent than
the other browsers. However, the object instance objXMLHttp is used in
the same way for both XMLHttpRequest and XMLHTTP, and it seems to
confirm with the working draft of W3C;
http://www.w3.org/TR/XMLHttpRequest. But, I agree, the comment could
sugest that it haven't been tested.

The XMLHttpRequest is just one example of AJAX without XMLHTTP.

Yes it is. IE7 uses a native object instead of an ActiveX object for the
XMLHttpRequest.

Think about what that line says.

As has already been mentioned the term AJAX implies the use of XML, but
it's sometimes a little fickle in my experience. Perhaps Roy made a typo
and intended to reference "http.responseT ext" instead of "XMLHTTPRequest ".

I always seem to run into small snags with XML and have resorted to using
simple character-delimited lists, when my problem domain doesn't require
anything more sophisticated. Here's an example of that, where my data page
will return a pipe-delimited list with 3 elements. For example:
"112197|1.46962 48|0.5309032" which is the primary key of my record,
longitude, and latitude.

Even though this is a bastardization of "AJAX" it works well and saves me
a lot of headache.
RESPONSE HANDLER:
function useHttpResponse () {
if (http.readyStat e == 4) {
if(http.status == 200) {
if ( http.responseTe xt.length ) {
var aLong = http.responseTe xt.split('|'); lngPtr =
document.getEle mentById(longAm t); latPtr =
document.getEle mentById(latAmt ); lngPtr.value = aLong[1];
latPtr.value = aLong[2];
}
}
}
}
