Ajax.response Max Size

Feb 24, 2007

I am using ajax / php where I am looking up some info from the
database and populating a select list dynamically, however I am
running into some sort of size limitation with the ajax.response
object. If the string I am passing to javascript from php is too large
javascript does not get it all the data. The magic number appears to
be 6123 characters, anything below that it works fine, anything above
and if I alert the ajax.response, I see the string is cutoff. Any
ideas where this limitation is defined?

AJAX Response Data Size Limit

May 18, 2006

I seem to be experiencing a character length cut-off with XMLHTTPRequest. I suspect this because the ActiveX .XMLHTTP works just fine for supporting IE. The data supposed to be recieved is a database outputting in an HTML table format. Any gecko based browser cuts off at about 4200 characters Code:

JavaScript As AJAX Response (RPC)

Oct 15, 2006

Some servers return JavaScript as the response to an AJAX request. When
the response JavaScript is eval'ed it calls other JavaScript functions
already in the browser to update elements, etc. This seems like a good
system because it allows so much freedom in creating the desired
behavior in the browser. The required data doesn't have to be converted
to XML or JSON on the server. The browser doesn't have to have
templates for interpreting and converting this data into some change in
the browser. All of the conversion algorithms don't have to be written
and changed when new behavior is required. This remote procedure call
approach is the predominant system in the Ruby on Rails world.
(Unfortunately they are calling Prototype.js functions.)

However apparently some people seem to think this remote procedure call
approach is a bad idea. I can't see why it is so bad because it is so
lightweight and flexible. It also helps to keep the client less
intellegent which seems good in a world of incompatible client-side
bugs.

If I use some neutral data format like XML to accomdate different types
of clients then I have to write different client-side interpreters for
each type of client (browser, RSS, POP, cell phone, etc). Why not just
write different server-side code that generates the correct JavaScript
(or other) for the requesting client type?

When is the RPC approach such a bad idea?

Ajax :: Wait Until Response Comes

Nov 15, 2008

I am using following code

Now what i want to do is: i have a callajax() function. with in this function i will call do_login() function. this do_login() handles an ajaxrequest and returns the responsetext.

Now i want to do some validation on this responsetext(in case of onsuccess). so i am trying to return value to callajax() function for onSuccess case in ajaxrequest.submit();

That is(onsuccess response) supposed to be some string( but not true or false). but i am always getting false in ajaxcall() function. i know the do_login() function is returning false before ajaxrequest completes

So i want to stop this and make do_login wait until ajaxrequest completes and then i want to return it's response to callajax() function.

I am wondering how possible it is to use eval() to parse javascrpt that is pulled in through ajax(innerHTML)? I have found a few notes about this, such as:

Run JavaScript That Is Part Of AJAX Response

Apr 12, 2006

In my browser, I make an AJAX request. The server sends me a fragment
of an HTML document. That fragment has some JavaScript inside some
script tags. How do I run these scripts when the fragment arrives at
the browser?

JQuery :: Ajax - Always Getting Empty Response?

Aug 27, 2010

I am making a call like -

$('#display').load(adnwurl, function(response, status, xhr) {
alert(response);
});

And also tried with -

$.get(adnwurl,
{},
function(data) {[code]...

In both the cases I am getting an empty response instead of expected html response.If I just copy paste this adnwurl in browser, I do get a proper html response. Its not working with ajax call.

adnwurl = "http [url]...site_id=4764&partner_id=70606a913077034c&timeout=5000&version=1.5&language=jsp&format=wap&testing=1&target_params=AGE=>29||DOB=>1981-08-[code]....

JQuery :: Ajax Response And .html()?

Dec 22, 2010

I'm using $.ajax for an ajax request and I've setup a basic html form and if there are errors in the form when the user submits them my server side script is returning them in an array to the client with the errors.

If there are multiple values in the array, how do I display each error on its own line either using <li> tags or even just a <br/>? I'm injecting the ajax response into a div using .html() but how do I iterate the array within that div so I get one error message per line?

Do I need to construct the HTML on the client side after the ajax response has come back or should I do this on the server side before the data is even returned to the client? Right now I'm returning a raw array so that is why I'm asking the question about how to format things up and get the form errors into my div.

Ajax :: Redirect To URL Response Not Working

Feb 10, 2009

I have a simple ajax request that is supposed to (after a short timeout) redirect the page to the URL that the server sends back but it just wont work. It does work without the setTimeOut() function however.

var http = false;
if(navigator.appName == "Microsoft Internet Explorer") {
http = new ActiveXObject("Microsoft.XMLHTTP");
} else {
http = new XMLHttpRequest();
}

function go() {
var u = "http://site.com/";
http.open("GET", "go.php?" + "u=" + u, true);
http.onreadystatechange=function() {
if(http.readyState == 4) {
var redirURL = http.responseText;
setTimeout("window.location.href = redirURL;" , 2000);
} }
http.send(null);
}

Firefox - Replacing The Whole Page By The New One In Ajax Response

Sep 24, 2006

We have the following situation - when Ajax request is sent what's
being returned by the server is usually an XML (which is used for DOM
updates) but sometimes it's HTML which is a whole new page that should
replace an existing one. I.e when we issue an Ajax request we don't
know what will be returned and analyze the response to act accordingly.

Now, the way to replace the current document with a new one used to be
easy and portable for both browsers (we're only supporting IE6 and
Firefox 1.5):

document.open();
document.write( head );
document.write( body );
document.close();

where "head" and "body" are two parts of the result HTML. We had to cut
it to two (rather than going simply with document.write( NewHTML ))
because of IE - our head section contains references to external
JavaScript files (<script type="text/javascript"
src="sth.js"></script>) and IE only loads them when document.write()
call ends. So if body contains any script block (<script
type="text/javascript".. </script>) using any of JS referenced by
head - IE would fail with something like "Resource undefined" if we
push the whole new HTMl in one go by using document.write( NewHTML ).
But it worked perfectly fine in Firefox, meaning

document.open();
document.write( NewHTML );
document.close();

did the job just fine. What's even more important - it also evaluated
all JavaScripts correctly - both in external files referenced by the
head and in the JS blocks embedded in the body.

Until Firefox 1.5.0.6/7 where things stopped working completely - our
lovely and used-to-be portable code

document.open();
document.write( head );
document.write( body );
document.close();

caused Firefox to loose all CSS/JS and display an HTML only page (as if
CSS/JS were disabled). Removing document.close(); improved the
situation a bit by displaying the page with CSS this time but still -
*no* JavaScript was evaluated (meaning, JavaScript blocks embedded in
the document's body were not evaluated).

I took a different path from this point by pushing the new content to
document's head and body "innerHTML". It worked but not for JS
evaluation - I had to do that manually. To evaluate the JS referenced
in the head section of the document - I've traversed the head's DOM
tree while looking for the "script" nodes, then downloaded all of them
one by one using a synchronous Ajax calls (don't laugh!) and eval()-ed
the response. To evaluate JS blocks embedded in the body of the
document - I've traversed the body's DOM tree while looking for the
"script" nodes and eval()-ed them.

The problem is following: eval()-ing external JS files after
downloading them with Ajax doesn't work in 100% of cases - some
statements using Prototype functions fail to execute ("prototype.js" is
one of external JS files referenced in the head). Anyway, I'm almost
sure that what I'm doing is plain wrong, i.e it's sounds silly to
download all JS files referenced in the head and eval() them !

So how do I fix it ? Simply put - how do I replce the content of the
document to the completely new one received as a response to
asynchronous Ajax call ? The new content conatins doctype, head, body -
it's a completely new page. And all JS referenced in the head and
embedded in the body should be evaluated as well.

I really wish

document.open();
document.write( head );
document.write( body );
document.close();

was working in Firefox as before. Is it simply a Firefox bug, should I
submit it ? Btw, document.open.write.write.close() works just fine in IE6.

Parallele Ajax, Parameters To Response Handler?

Aug 12, 2007

i'm new to ajax. simple request no problem - but it seems when I set
the response handler function, I can only pass the function name and
not give parameters, so I have a problem when starting e.g. 5 ajax
requests parallele. how to do that correctly? for one case, where I
used *different* resp. handlers, I solved the problem by global
variables - but now I have a loop of e.g. 20 calls to the *same*
r.handler and I don*t know how to tell the function *which* request of
the 20 to use. I expect the solution to be simple but how..

JQuery :: Ajax Response Time Inconsistent?

Feb 27, 2011

What I'm doing is creating a div element dynamically when the user clicks on a point in the page. Once created I create a record in my database table the corresponds to this div element and save information such as the width,height, x coordinate, and y coordinate of the element. This is done via AJAX accessing my web service. The weird thing is, I get really fast responses 80% of the time but 20% of the time, its taking a lot longer. For example, I would get a response after 50-100ms and at times I would get it in 2 seconds What do you think is the source of this problem?

JQuery :: Initialize Plugin After Ajax Response

Aug 26, 2010

I'm initializing a lightbox type plugin after an ajax response. The plugin is usually initialized with .ready, but I've read on this forum that .ready won't work after page load or with dynamic loading. Most posts say to initialize right after the ajax response... I've done this and it works for the first ajax load, but not for the subsequent ajax loads. It should trigger the same code every time ajax is called since it goes through the same function, but it doesn't.

Project Info: This project seems pretty simple... There are links that load content into a DIV via ajax... the content is made up of thumbnails that should launch lightbox...Is there a good way of dynamically initializing plugins after ajax load?

JQuery :: Slow Response To AJAX Calls In IE7?

Jul 30, 2009

I am developing quite a complex user interface in jQuery that relies on an AJAX call to retrieve JSON.We have noticed that the code runs slow in IE7. IE8 and IE6 are acceptable. Firefox and Chrome really quick. I have traced the problem back to the AJAX call, which IE7 seems slow o process. What takes less than a second in the other browsers will take IE7 3 or 4. I have googled for an answer it seems there is some consensus that the native XHR in IE7 is slow, so it may not be a specific jQuery problem.Has anyone else experienced this? Does anyone have a solution? Please consider that this will be a public website, so the solution cannot involve altering settings on users' machines.
