View 1 Replies View RelatedI was wondering if it was possible to execute javascript returned by ajax (XMLHttpRequest)? I can see that the script is returned by it doesn't execute. Here is what it returns. I can see the output but when I click on it nothing happens.
Code:
<script type="text/javascript">
function hi(name){
var latBox = document.getElementById("myinfo");
latBox.innerHTML = "<div>Greetings: " + name + "</div>";
}
</script>
<p onClick="hi('hi');">Math.random = " + Math.random() + "</p>
I came across the same error and have modified the code from
<a href = "" onClick = "javascript:somename( );">somename</a>"
to
<a href = "javascript:void(0);" onClick = "javascript:somename(
);">somename</a>"
In somename( ) fn i am using AJAX to retrieve the value and whenever i
click on that link [old code] it takes me to current page itself
without giving any AJAX response, that too only in Mozilla browser.
After that i changed the href attribute value to "javascript:void(0);"
and it works well without any error.
So this is the situation i came across. I dont know whether the above
info will help you guys?
There's something I can't understand. If I do:
Why does jQuery return elem1 and not the created element ? Returning the created element does much more sense to me since:
a) I already got a reference to elem1 if I need to do further manipulation.
b) I got a references to the 'div' element I've just added.
The way jQuery does it, I'll never get a references to the element I've added.
Can anybody clarify this for me? Is it a 'jquery way' to work this?
I find ajax with jquery more confusing than with regular JS, b/c in jQuery you don't declare XMLHttpRequest object.. so how do you do something like:
In example I mention here,[url] namely [url] I don't understand where var 'msg' is declared, I know it comes from the back-end, but HOW is it passed to the front-end? (how do you do this w/o responseText or something similar?)
I'm trying to connect to a send-mail jsp with ajax.. the email is not getting sent.. I want to test if the ajax connection is being made at all.. don't know how do it w/o something like xmlHttp.responseText
This is my jQuery ajax code for connecting to send-email jsp:
var dataToSend = "name=sName&email=sEmail&msg=sMsg;
I call a query, get success, but don't know how to get the data out. Here is the code..
[Code]...
An object is returned, but I can't the data out of it.
The below code posts a couple of vars to a php file which sends back a json object containing (in the test case) one object called 'faves' with 2 variables (let's say called var1 and var2). I can't seem to access the variables after the ajax call. The result is always an 'undefined' error message. I've tried:
console.log(data.var1)console.log(data.faves.var1)
console.log(var1)
All to no avail. Can anyone tell me what I'm doing wrong here? I have checked with FireBug that all the data returned is good and well-formed etc.
$(function() {
$.post("<? echo base_url(); ?>test.php", {
id: "<?php echo $id; ?>",

Im trying to figure out if a public picasaweb userid exists or not. Its a pure client app, so no server-side proxies. The 1st method works only on FF & Chrome.

in my javascript code I'm using a synchronous XMLHTTPRequest to periodically fetch a file from a server. Recently I added the "If-Modified-Since" header request (to reduce downloads if nothing is modified). Since adding the "If-Modified-Since" header request the javascript code still works with all browser (IE, FF, GC, AS) besides Opera.
The issue only happens if there is no new file to be downloaded: with the other browser I can see the 304 request status code, while with Opera (opening dragonfly) the request remains indefinitely as "in progress", the request status code returned being 0.
function XML_request(func) {
var onreadystatechange= func;
this.method = "GET";
this.get = function(url) {
var request = null;
var state_change = function() {
if (request.readyState==4) {
if (request.status==200) {
onreadystatechange(request);
} else {
return null;
}
}
}
try {
request = new XMLHttpRequest();
} catch(e) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {
return null;
}
}
if (request===null) {
return null;
}
request.onreadystatechange = state_change;
request.open(this.method, url, true);
request.send(null);
}
}
var req = new XML_request(function(response) {
response = response.responseXML
alert(response.getElementsByTagName('blah')[0].firstChild.data);
});
req.get('index.php?mode=blah&a=response')
i didn't like the examples I found so this is suitable.. I only tested in ie and firefox though.. so let me know what I may be missing.. or criticism in general.

I am trying to create an xmlhttprequest object to update the shopping cart on my web page without submitting the entire page to the server for processing. However, what I have done so far is not working. All that is happening when I click the "update cart" button is the page sort of flashes and the check marks in the remove item check boxes disappear. The first code snippet is the "traditional" way of submitting the whole page to the server for processing - and it works. The second snippet is what I have done to try and implement AJAX to submit only the shopping cart - and it does not work.

I've created a small AJAX library for our application. We send the response data back as JSON in responseText. So far so good.
Before we invoke the response handler, I'm putting the eval'ed responseText in the request object like so:
Code:
req.respText = eval('(' + req.responseText + ')');
This works in FF but breaks in IE 6. (*gasp*)
I finally got the Microsoft Script Editor yesterday, so I could play with the values and see what was going on. Kind of... I'm still in the dark. For some reason, it won't let me add a property to req. Can anyone explain why/how it prevents me from doing so?
Conceivably I could add the eval'ed responseText to the response handler function, but that would break the API, and would require us to modify a bunch of existing functions.
Im trying to set request header of my XMLHttpRequest object.
Code:
xhr.setRequestHeader("Content-Type", "text/xml");
and it gives this exception

I am having some difficulties getting some inline js code to run when
retrieved via AJAX by XMLHTTPRequest.
Basically I am running a php script every 15 secs or so that does a query of
a mysql database, checks to see if any new chat requests have been sent to
the user, and if so, it is simply returning them via a "echo" statement, and
the info is placed into a DIV in my sidebar.
Now when I add something in like:
<script type="text/javascript">
alert('you have a chat request');
</script>
it runs if i go ahed and run the script by itself, i get the chat requests
and the alert to popup. When the script is called via AJAX and loaded into
the div, I get the message from the mysql query about chat info, but no
javascript alert.
Am i just missing something stupid here? Like I said, it works when I run
the script by itself, just not when called via XMLHTTPRequest.
I am trying to xmlhttp object using ajax. In my first request I am getting the desired result. On the readystatechange I called a function whic process the response of the first request. According to the response of my first request, I fired the second httprequest. But the second httprequest always returns a status code 0. I got a message called request cancelled.
View 3 Replies View RelatedI want to update an element in my DOM that contains Javascript code when an action X is performed and an AJAX response generated with new Javascript code that is one of the AJAX response variables.
The AJAX request is successfully returned, as is the Javascript JSON response variable. However, I'm having no luck updating the DOM element containing the old JS code with the new JS code. I'm performing these operations using JQuery.
I am going to use the server push
for streaming the data by keeping the connection open. At client side,
i am having the XMhttprequest object (i.e ActiveX object of IE). When
the data comes, onreadystatechange method get callback on state 3 but
it doesn't allow me to read the data from the object. It says 'The data
necessary to complete this operation is not yet available'. Is it
possible to read the streaming data from the XMLHttprequest object in
IE?
I know Mozilla supports to read the data, when the ready state is 3. In
Internet Explorer, how we can use the XMLhttp Active object to read the
streaming data.
Say I have 2 HTML pages. In page A, I want to display part of page B.(content between a div tag pair with ID in B) Now I was able to use the XMLHttpRequest object to get the complete page B, namely, through the reponseText property of the XMLHttpRequest object. But my goal is only part of page B, not the entire page. I tried to use XML DOM tree node methods to extract the wanted part from page B, but it does not work. I think the problem is that page B is a HTML page, not a XML page. Is there a work around on this?
View 2 Replies View RelatedI am trying to write a tool (say [URL])The tool contains a list of https urls (say [URL]) given as a hyperlinks (say abc) on clicking the url the http status code of the https page should be displayed in the same page.. Is this possible? I am currently using the following code snippet..
function sendRequest(url){
var client = new XMLHttpRequest();
client.onreadystatechange = function(){
if (this.readyState == 4)
alert(client.status);
} client.open("GET", url, true);
client.send(null);

This seems to be working if the url given is http url but I have to get status for https url for a non-secure (http) url.
I stumbled upon a strange behaviour of the XMLHttpRequest.. Maybe I'm
just not well informed enough about its possibilities, so could someone
please confirm my question?
When I put plain javscript in a file that is read-in through a
XMLHttpRequest-object, it's like it is totally ignored. Eg. I have the
file ajax_include.html with in it's body the following lines
<script type="text/javascript" language="javascript">
alert('some alert');
</script>
when I directly surf to the file, the alert pops up as expected, but
when I use a simple XMLHttpRequest to replace the contents of a div
with the contents of this page, the alert is not popping up, although
when I view the selection's source (Thank you, Firefox!), it is there!
When I place an anchor with an onclick-action (eg. alert('onclick')),
it works when I click it.
So my "conclusion" is that it seems like inline javascript commands are
ignored (functions not recognized etc.). All actions assigned to other
events work nice though.
Can someone confirm this strange behaviour? Or is it just normal with
the use of an XMLHttpRequest opbject?
I'm making a script that requires cross-domain scripting to get the statuscode of other files. I'm currently using a small PHP script to relay the files from the remote server onto mine. If I want to get the files directly using AJAX, it is not allowed for obvious reasons. I don't want the actual files, I only want to get the status code of that file, and it is going to be either a 404 or a 301. I would've assumed that as the AJAX call is never attempted, the statusCode will be 0, and this is what the actual call variable returns.
However, in Firebug it shows the statuscode next to the request (404 or 301), even if, the call has never been made. Why is the statuscode appearing in Firebug but not in the statuscode variable?
Can any tell me javascript code that will control the browser progress bar which is located in the status bar. I want to control that progress bar so that I can notify the user about the completion of file uploading.
View 2 Replies View RelatedWe've been using ajaxSubmit to process a login form request (can be found here: [URL] Login Link in navigation). However when we attempted to upgrade from 1.3.2 to 1.4.4, we get the following error whenever we submit the form:
"jQuery(this).ajaxSubmit is not a function"
The only way we've been able to get the form to work again is to go back to vs. 1.3.2.
Has something changed in 1.4.4 that would prevent the form from working? Is "ajaxSubmit()" no longer a valid function?
Here's the javascript below:
jQuery(document).ready(function() {
jQuery("#show_login").click(function() {
formLogin();
jQuery('#user').focus();
