Javascript In Ajax ResponseText

May 1, 2006

I'm making an ajax call to return the contents for a page using the responseText property. I want to be able to define a javascript function in the page and call it, doing something like:

<script>
function test(){
alert('hi');
}
test();
</script>

However, none of the javascript in my page works. I'd imagine it has something to do with it being included as part of the responseText and the browser is not picking it up. I haven't been able to find any info about this online anywhere. Any thoughts?

Ajax :: Return Xmlhttp.responseText From Function?

Jun 9, 2011

I've been racking my brain for a couple hours now and doing a lot of searching and I cannot seem to find an answer. I want to know if it is possible to return the xmlhttp.responseText value from an AJAX function to the function that originally called the AJAX function.

Code:
//Set handler for server response.
xmlhttp.onreadystatechange = function()
{

[Code]....

I want to return the my_response variable to the original caller. No matter what I try I have been unsuccessful. I even tried assigning it to the global window variable using window.my_response = xmlhttp.responseText but it ends up being undefined.

Every example I've seen of using AJAX pretty much does something inside of the if (xmlhttp.status == 200) part to update the web page. I really do not want to do that.

Can I return the value?

Feb 25, 2006

I'm fetching some HTML files with XMLHttpRequest and dumping the

FireFox)

What's going on ? What is the workaround ? I've tried this:

divElement.innerHTML = x.responseText.replace(/?/g, "'")

IE ResponseText Is Empty

Feb 24, 2011

I'm trying, to fill a table with data I receive from a Servlet. In Chrome everything works fine. But when I try the app on IE the responseText is allways empty. The following is my JS code (using prototype):

function updateToDeleteTable(){
var url = 'getDefHidConFechaInsercionMayor?plantacion_id='+$('plantacion_id').
options[$('plantacion_id').selectedIndex].value +
"&fechaDesde="+$("dateSelect").options[$("dateSelect").selectedIndex].value;

[Code].....

I know the servlet returns a correct text, because when I enter the request uri in a new IE tab it returns the appropiate html code.

Allso when I check the variable response in the IE JS debugger the resaponse of the servlet is 200 (OK). I realy can't think of anything I'm doing wrong, exept, that maybe there is a size limit for the responseText.

Keeping Whitespace In ResponseText, Etc.

Aug 24, 2006

I'm trying to access the source of an HTML page with as few alterations
from the actual source (as in, that seen from the View Source option)
as I can. The method document.documentElement.innerHTML returns the
HTML source, but adds HEAD and other elements if they are absent from
the source, and takes out whitespace (i.e., line feeds, carriage
returns and tabs) within tags and between tags. The follow function:

function xhr() {

xhr = new XMLHttpRequest()
xhr.open("GET","test-page.html",true);
xhr.onreadystatechange = function() {
if (xhr.readyState==4) {
alert(xhr.responseText);
}
}
xhr.send(null)
}

doesn't add or alter any tags that are absent in the source, and does
not take out line feeds within tags; it does, however, still take out
all non-line-feed whitespace within tags and all whitespace in general
between tags.

It seems that preserving whitespace is all that I need, but I haven't
found a way to do that through my searches. So is there any way to get
the unaltered HTML source of a page without innerHTML or applets, like
a better version of the XMLHttpRequest object's responseText method?

AJAX, Eval(), And Javascript Within Javascript

Apr 28, 2006

Ok so, this is my purpose:
- to be able to load asynchronously (via AJAX) some javascript ads (like google's or adbrite) so as to make them be loaded in the background, then update the page after the ads have loaded via innerHTML

Why?
-Because 90% of the time in my newer sites, javascript ads are the major offender in terms of speed of page rendering

My problem:
Via ajax, I can call a php file that retrieves some javascript and outputs it, XMLhttprequest returns those javascript lines, but they don't render in the page, since they miss the whole page loading, and are apparently not parsed
For example, let's say I call a php file via ajax, and it returns the output into a variable named "text" containing "document.write('hello')"
if I use xxx.innerHTML=text, nothing happens

My 1st solution:
Passing those javascript lines to eval() [like eval(text) ], but this produces a second problem, that I couldn't solve (probably because of my lack of knowledge in javascipt):
if I eval the code, it deletes my current page and renders a new one
for example, if I parse a document.write, my page disappears, and a new one is rendered with the document.write text

What I want is basically to make that "document.write" appear inside a div in my page, adding to the content (and not overwriting the whole page), much like what happens when using innerHTML

Is this even possible? How would you go about it?
I tried xxx.innerHTML=eval(outputfromphpfile) but it overwrites my whole page...

Make Responsetext Elements Navigable With HREF

May 31, 2009

I'm not really a programmer, but have been tasked with performing some AJAX functions to make a call and return results to my page using getElementByID. I have been able to return search results to the page, but now need to make them clickable as it will lead to another query. E.g., when a user clicks one of the returned categories, it should invoke a query to return products within that category.

Right now, I just want to see how to effectively wrap an HREF around each search result.

Here's the page I'm working on: [URL]

Here's the javascript I used to return the results to that DIV:

function setDataHTML(xmlHttp)
{
document.getElementById('CollapsiblePanel2').lastChild.innerHTML = xmlHttp.responseText;
}

how to make these results clickable?

Getting Started With Javascript And AJAX

Aug 30, 2006

I'm interested in learning Javascript with an eye towards using it for
client-side user interfaces for web services, and I have a couple
questions.

First -- In reading some of the archives here, I've noticed a fairly
strongly held opinion that it is better to write purpose-built
Javascript than to use large libraries. Since this was what I was
planning on doing anyway, because of the size of the libraries and
compatibility quirks with Safari, it's nice to hear confirmation from
experts. That said, is the code in Prototype, Scriptaculous, and
OpenRico good enough to be worth reading and emulating?

Second -- I do much better with dead-tree references than with the
web, especially as a lot of the links that come up when I google for
Javascript topics are tutorials for the clueless by the clueless.
(Perl has the same problem, but with Perl I have enough knowledge to
filter the useful bits from the flat-out wrong bits.) Aside from the
O'Reilly Javascript reference (which I have) and _Ajax Hacks_ (which I
also have), are there other good references I should get my hands on?

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?

Javascript On AJAX Request

Feb 16, 2007

I am currently creating a social network. On a profile if a user has comments they can delete them. I am running AJAX to update the database and display the comments refreshed (one deleted will no longer show). The data I am requesting includes the following...

<script language="JavaScript">
document.write("<a href="javascript:void(0)" 'CommentsTable', 'PostLink1', 'PostCommentText', 'ViewCommentsText')" id="PostLink1">Post Comment</a>");
</script>
<noscript>
<a href="comment.php?action=post&user=<?php echo $user; ?>">Post Comment</a>
</noscript>

My problem is that the JavaScript from the request does not work, I can only seem to display regular HTML. Is there a solution to this problem to make the JavaScript work or do I have to use an HTML alternative?

Overhead A Javascript Tookit A Necessary Evil For AJAX?

Feb 28, 2007

I am currently running a website for a medium sized company that has an application which relies heavily on AJAX. Currently, I am using DOJO, and it does a great job when it comes to cross-browser compatability. It comes with so many extras, and clients are forced to download these extras!! I have looked around at various other Javascript applications, and, while some vary in size, it seems that they are all quite large. Are these toolkits neccessary for a functioning ajax application? Must clients download an extra 30 - 150kb of js to use AJAX? In an attempt to solve this problem, I threw a script together with some help from the internet and an Ajax book that weighs in at 1.2kb. I would love to just throw this up and be done, but I don't have the testing capabilities to justify doing so. There are so many flavors of browsers, and I have access to only a few of them. Frustrating Don't really know what i'm asking, anyone else run into this frustration?

Dynamic Content Replacement Using Ajax/Javascript/PHP

Jun 26, 2007

I'm sure some wizard will tell me this is a classic example of "piece of cake"; in which case I bow and promise to listen In case I've struck granite rock, feel free to throw questions my way and I'll tell you if I've tried it or not.

I have a file, main.php (I know this is the JS-forum, bear with me). It outputs HTML and inline Javascript functions. When the user clicks on a graphical "tab", that tab is activated, and an ajax call is made to fetch.php with some specific parameters. Once the ajax request has completed, a given innerHTML container on the now active tab is filled with the stuff that fetch.php outputs.

So far so good.

The problem is that the stuff that fetch.php outputs is partial pure HTML and partial inline javascript. And this is where it gets tricky. If I declare an inline javascript function in the returned data, Firefox (and I suspect MSIE) refuses to understand that the function is there. It simply doesn't exist (!).

Using the Web Developer add-on for Firefox, there's an option to look at "Source code" and "Generated source code". The output from these two differ in that when I view the "Generated source code", I see the dynamically inserted javascript/HTML from fetch.php, whereas viewing "just" the source doesn't.

What did I do wrong? How do I get the browser to find/accept/activate the javascript code/functions that were inserted dynamically? I cannot put them in a .js file and include it, since they need to be dynamically created, and I cannot use eval() since that executes javascript "as is", in which a function will not be executed unless called.

One specific example of the problem I'm having is creating sortable lists with scriptalacous. It works great if I access the page directly, but if I access the page using an ajax call the javascript of the page doesn't seem to fire.
