JS Problem In An Ajax Script : "undefined" Result
Jul 12, 2006
well i've a display problem in my ajax script, my script ask to the server a message every x seconds so when i receive it, i display it in a div element with innerHTML. But the first message of the first time i launch the script in my page i see 'undefined', like :

The problem is solved when i redo the script without reloading my page. Like an element which didn't exist yet... How can i fix this?

I have several divs called 'profile', 'codesamples', 'artportfolio' and 'resume' which are hidden. I also have a visible div called 'bodytext' which is visible. When you click one of the links on my page, the function ClickButton is supposed to run, and send the information contained in one of the hidden divs into my visible 'bodytext' div. Instead, I get 'undefined' when I click one of the buttons.

My webpage can work normally in IE but not in Safari(e.g. when I clicked on some buttons like 'Delete' button, the page opened in Safari stays the same while it should delete the object chosen).
When I tried debugging on Safari, after clicking the 'update' button, this message error appeared: "TypeError: Result of expression 'this.form.fireEvent' [undefined] is not a function".
I believe this code makes the incompatability between the 2 browser:
How should I amend the script for it to work on 2 browser concurrently?

I am not a javascript programmer, however are checking as I would like to investigate if I can do following:
I have a calculator that check the price for the properties for a choosen date, I use php and mysql to get the result and the result are displayed on the same page refreshing the page using this in the form: action="<?=$_SERVER['SCRIPT_NAME']?>#formdestination">
I know you can print the result using ajax or other javascripts to do this without having to refresh the page and jump to the result.
Was doing a research and I quckly found this link:[URL]..It does not look so complicated, however as I can see the form is done in javascript so I suppose if you have javascript disabled you cant use the calculator.
I would like to have a non javascript solution with the way I am doing it to work if javascript is disabled. An exampel of the calculator can be viewed on this link for exampel:[URL]..

Have developed a Joomla AJAX search module for VirtueMart .
Works fine in everything except IE.
I know the reason is IE's limitation in innerHTML (block level html not allowed in inline)
The problem is the returned html from the AJAX call contains a form so IE throws an error.
To fix it I need to filter out the result before setting the html in the div, in other words select just the elements I need before doing the setHTML.
I've tried everything but I just can't get the syntax right.
Here's what I have
Code:
var req = new Ajax(url, { method: 'get', delay : 300, data: { 'option' : 'com_virtuemart', 'page' : 'shop.browse', blah blah },
onComplete: function(results) {
var theNewEle = new Element('div').setHTML(results);
[Code]....
So what I need to do is target the div class="browseProductContainer and setHTML only that.

I'm new to jQuery and I'm having a bit of a problem manipulating AJAX results with jQuery methods.
I use an AJAX get and execute the find() method on the resulting output. But this seems to work only once. Subsequent attempts using the same selector in the find() argument don't work. Different selectors will work, but again, only once.

I am calling an AJAX function from a certain method, but for any reason it does not return the result.
The JSON object is "Records". The URL is build within another method and properly passed (as I can see in Firebug)[code]...

I have a text-box. On the event of `OnKeyup` a function is triggered that looks like this:
$.getJSON(url,function(data){
$.each(data, function(key, value) {
showSearchResult(value);
});
});
No my problem is that when you type really fast then the return search result does not always return relevant to the current value of the textbox.
[I did think of adding a very small time-interval on the onkeyup event but i thought there might be a cleverer way of doing it ]
This problem is because the Ajax calls do not sometimes return in the same sequence that they were fired.

I have to following piece of code:
var myarray = new Array();
$.ajax({
url: 'http://distantserver.net/path/script',
dataType: "jsonp",
data: {
[Code]...
It's a cross-domain request. The first console.log() debug message prints the desired result, the second doesn't. It seems that the variable myarray has its scope limited to the success-callback. How do I get the data out of the success-callback?

In firefox, i look through the DOM and its showing me that both xmlHttpRequest and ActiveXObject("Microsoft.XMLHTTP") are undefined.Also if one could check the ready state methods I used, I'm not 100% if they are correct eg. xhttp.onreadystatechange = loadBlurbs() and if null is the value for a failed loading procedure.lasty, can I do this processBlurbs() = getElementByTagName, and then, processBlurbs() { this.length, this.child etc. ? }
Code:
<script type="text/javascript" language="javascript">
var blurbdoc;
var blurbs;[code].......

This piece of code is used for an AJAX function, it works perfectly well in all other browsers than internet explorer.
// JavaScript Document
// store xmlhttp in a variable
var xmlHttp;
function xmlHttpRequestObject () {
// assume we're working with a newer browser
try {
xmlHttp = new XMLHttpRequest();
}
catch(e) {
// assume IE6 or older
try {
xmlHttp = new activeXObject("Microsoft.XMLHTTP");
}
catch(e) { }
} .....

I have been trying to figure this out for a few days now and have finally come to the point where I think I got it but may just need a little push to get what I want.
Heres the situation:
I have this function that uses ajax to access a database and returns the results in the responseText. That part is working fine, I have confirmed that the responseText contains the information that I need
**************code*****************************************
//new ajax already created and assigned to the variable xmlhttp//
var response_recieved = "some data";
function get_answer(Table_Name, Field_Name, Data_Type) {
[Code]....
As evidence by my posting, this is not working correctly. The variable response_recieved is coming up undefined outside of the callback function assigned to the onreadystatechangeproperty.
Based on the information that I have gathered online from various forums, I believe this issue has to deal with a problem with closure in the callback function assigned to onreadystatechange property. I don't think it has any. Based on the fact that there is no anonymous function in that function. But my problem is that the call back function is anonymous itself... I think???
get the variable response_recieved to survive outside of this function.

I can not for the life of me get an ajax example/tutorial to work. I have tried dozens including prototype library and JQuery.
Here is my latest attempt:
As you can see I am trying to alert the variable teamH but I keep getting an undefined in the alert. I also tried a static drop down and I received the same undefined alert.
How I get that variable to contain my drop down choice?
