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?

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?

Below is JS code:
Code:
var request = new XMLHttpRequest();
request.open("GET", "http://127.0.0.1/get/file.json?filepath=c:\xxx.xxx");
request.onreadystatechange = function() {
if (request.readyState == 4) {
[Code]...
using above code, I wanna implement uploading/dowloading/parsing file with json format. however, the responseText always return null in FF. It it about to make me crazy.

I'm fetching some HTML files with XMLHttpRequest and dumping the
ResponseText into block elements; works fine except that single and double
quotes are being displayed as question marks (inside of a black diamond in
FireFox)
What's going on ? What is the workaround ? I've tried this:
divElement.innerHTML = x.responseText.replace(/?/g, "'")
but it does nothing ... even if it did work it would not be distinguishing "
from '

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.

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?

Using the following code:
var plabhttp = createRequestObject();
function getPowerLab(){
if(plabhttp.readyState == 4){
var plabresponse = plabhttp.responseText;
document.downloadForm.powerlab.value = plabresponse;
}
}
Problem is that in firefox the variable plabresponse displays nothing. However in IE it comes out ok.
Has anyone seen this before?

I am using AJAx to call a method on the server which sends a mail to
the user.
my code if(status == 200) is evaluating to false yet the mail is
delivered. But because of the above status I am un able to display the message to the user. Do any one hava an idea how to access responseText or ResposeXML
without status=200 because my prime target is to display messages in the user interface.

I need to turn xmlhttp.responseText into a column of links that will be displayed in a popup div.I've defined xmlhttp.responseText as var named txt with: var txt=xmlhttp.responseText;
That produces a var with comma delimited values. I'd like to proceed by passing txt through a For Loop that will create the links, but I can't find a method that will count commas.
How do I return the number of commas in javascript?

I am using JSP with AJAX. After a certain JSP script is processed the output is sent to the responseText. Now, I want to check what output responseText consists so that i can perform further processing. For eg, I want responseText to contain"yes" or "no" and depending on what it contains i want to execute client side script. I hope i have nt confuse you.

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...

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?

xmlhttp.responseText = "Bob , Brittany , Brian"
var txt=xmlhttp.responseText;
var txt2 = txt.slice(0,txt.indexOf(","));
slices off Bob. How do I get all three into a var with line breaks between them so I can display them with
document.getElementsByTagName('body')[0].appendChild(div);
document.getElementById('link_container').innerHTML=????????;
