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?
None of my getElementById (or other) references produce anything but "undefined." This occurs in the latest versions of Fx, IE, Chrome, and Safari, so it must be something I am doing but not not seeing here. I have boiled it down to the following without success, and wonder whether there is some add on interaction. Fx 3.6.12 has the problem with this code:
<code>
<html>
<head>
<title>This is a test of getElementById</title>
</head>
<body>
<div id="area" name="area_name">xxx</div>
<script type="text/javascript">
var divs = document.getElementsByTagName('div');
var msg = '';
msg = 'Divs[0] contains ' + divs[0] + ' with width = ' + divs[0].width + "
";
msg +='Test area width by id = ' + document.getElementById('area').width + "
";
msg +='Test area width by name = ' + document.getElementsByName('area_name').width;
alert(msg);
</script>
</body>
</html>
</code>
This function was working in Safari but not in Firefox. I was referencing a couple of elements using the forms[] array instead of getElementById(). I changed those refernces to use getElementById() and now the calculateTotals function does not work in Safari or Firefox.
So I did an alert box to see ucell and it was null. I tried two more alert boxes for the id I was passing to getElementById and for the id of the actual element on the page (which was also created dynamically). They were both identical. The element is created in the onload event, and I am not calling the calculateTotals function until there is onchange event on a text box. So it is not that the element has not been created yet. . Code:

Is there something wrong with my script? Typo?
function accite() {
bq = document.getElementById("content").getElementsByTagName("blockquote");
q = document.getElementById("content").getElementsByTagName("q");
alert(
"<blockquote /> = " + bq.length +
"<q /> = " + q.length
);
}
It's saying "document.getElementById('content') has no properties", and yes, I definitely have a <div id="content" />.
I am working on a very simple code to determine the highest value from an array and also use parallel arrays.
The problem I am having is, when I try to invoke the parallel array namesArray it returns undefined.
I have coded the function so it can be used to find the highest value in more arrays as this is only the beginning of my code. Im not sure if this is what is causing the problems but I have a feeling it is code...
Here is a clip of code from a script project im working on. Now my document.getElementsByTagName is returning a "undefined" value.
<a href="[URL]" style="text-decoration: none; color: #EDDBAF; font-size: 16px;">
<center style="margin-left: 10px; margin-right: 10px;">
<font style="color: #EDDBAF; font-size: 16px;" id="title"></font>
</center></a>
<li id="name"><a http="[URL]" style="color: blue;">John Doe</a></li>
<script type="text/javascript">
var pname = document.getElementById('name').getElementsByTagName('a');
Now if I remove the ".getElementsByTagName('a')" it will actually work, but it also includes the <a> tag thats within the <li> tag, which I don't want.
document.getElementById('title').innerHTML=pname.innerHTML;
</script>
I have a following snippet

I could see the individual values in each index in firefox, but ie is displaying as undefined.
know whether this is not allowed in IE?. Is there any workaround for this?.
I am using getJSON to get results from a different domain and i wantedto get _some_ object back when calling getJSON so that i can insertsome variables into the callback scope.Basically, what i wanted to do was this:
var new_json = $.getJSON(url, function(data) {
alert
(this.variable_from_caller);

I have a function where in I call another function that assigns a value to a var. code...
For some reason my code below is returning 'undefined'. But when I place an alert(); before the 'return' it shows the correct value. However when I place an alert(); to show the var that is set to what the function returns it says 'undefined'.
Firebug throws no errors. I am using a little bit of jQuery.
Here's the problem: I have several hidden divs containing information. When you click on a link, javascript executes which is supposed to move the appropriate info from one of the hidden divs into the visible 'body' div. The javascript isn't working, though, and I'm getting 'undefined' instead

Using jQuery v1.4.2, Firefox 3.6.6, Chrome 4.1, IE 6,7,8.
I'm using jQuery .css() function to get the value of the css attribute "background". The attribute has not previously been assigned a value (either in script or style sheet).
e.g. alert($(this).css("background"));
In Firefox and Chrome, the return value is an empty string (""). However in IE 6,7,8, the return value is "undefined".
It also makes the following statement impossible:
alert($(this).css("background").indexOf("somepic.gif"));
Because css() in IE doesn't return a blank string, doing indexOf() raises an error.
cross-browser scripting compatibility, for jQuery to return a blank string *for all browsers* if the css attribute isn't set. Otherwise we have to check for both "" or "undefined" which is the sort of pain jQuery users are trying to avoid.
Currently, I'm building a website with jQuery. The function below helps me to get content from a database. In the file content_ajax.php there are some functions to handle ajax-requests. JS calls the PHP-function correctly (I've send an email to myself inside that function to check) but the script doesn't return 'succes' and doesn't give me an error...Also, when I put an alert inside the succes and error function, it doesn't popup!

if it's possible to return an array from my php generated content to ajax's responseText. I tried echoing back the whole array variable but can't seem to fully receive it in javascript.
somewhere in file1.php
<?php
$myArray = array();
$myArray['name'] = "ajax tech";
$myArray['age'] = 20;

I'm attempting to simplify my javascript code when it comes to ajax, but afterwords it only prints 'undefined' to the screen rather than what I want it to print.
I want to be able to put something like this on my main page onclick="document.getElementById('output').innerHTML = print_output();" where print_output() is the ajax function. This way I don't have to use a function to assign values directly to innerHTML and I don't have to muck about with a js file whenever I want to change my page layout.
To do this, I created a recursive function:
function print_output(return_value) {
if a value has been passed to the function, simply return it
if(return_value || return_value == 0) {
return return_value;
}
[Code].....
but like I said, it prints 'undefined' out to the screen. Why isn't this printing the contents that it receives from 'index.php' like it's supposed to?
I'm having trouble placing some data returned by an ajax function in the page where I want it.
I've included the relevant html and the javascript function below. There is some php code included which works but is not relevant to this question. The first ajax part of the function works. I have tested it with positive results in another context.
The part starting with "var x . . ." is the part that is not working. This part is supposed to generate the following html: Code:

How do i return many lines of data?
The page eventos_search.php is supose to get more then 1 line of records
This process i dont know how it works.
i happen to chase my fortunes in development as a newcomer. Scenario,// using jqm-rc2, sample registration - ajax callback scenario
1. Say formtoregister.phpcalls a studentsregister.php // Ajax/json and POST
2. Thisstudentsregister.phpdoes this 2.1 validates POST data, does db work and 2.2 sends back to formtoregister.php following messages //on success echo json_encode($promoinfo);// json format, see below the echoed content echo "<p>Welcome $user </p>" problem,is plain format text is printed Message is: {promo code: JsonNAjax}<p>Welcome Beginner </p>

I am running the scripts below which should return a string containing a URL.So far, it cannot find the form contents in Firefox, but displays the non-dynamic data such as ?Location=. It won't work at all in IE.
View 1 Replies View RelatedI'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?
I'm doing some jquery and ajax work with C# asp.net MVC on the server.

What I'm wondering is there ways to return values from DeleteListing on the server to the success function?

A while ago I wrote a "Vector data type" script
using DOM interface to select.options.
That was a (beautiful) mind game :-) rather than
a practical thing to use.
Here is another attempt open for criticism, this
time dead serious. I really need an effective
Vector emulator for a project (as much effective
as something not implemeted in language but
emulated by means of the language itself is: a
productivity impact is imminent, the question
is to minimize it).
<html>
<head>
<title>Vector constructor</title>
<meta http-equiv="Content-Type"
content="text/html; charset=iso-8859-1">
<script>
function Vector(arr) {
this.$_$ = arr || new Array();
this.length = this.$_$.length;
this.add = Vector.$add;
this.remove = Vector.$remove;
this.toString = Vector.$toString;
}
Vector.$add = function(m,i) {
if (('number'!=typeof(i))||(i<0)||(i>=this.$_$.length)) {
this.$_$.push(m);
}
else {
var tmp = [m];
tmp.push(this.$_$[i]);
this.$_$.splice(i,1,tmp);
}
this.length = this.$_$.length;
}
Vector.$remove = function(i) {
var ret = this.$_$.splice(i,1)[0];
this.length = this.$_$.length;
return ret;
}
Vector.$toString = function() {
return this.$_$.toString();
}
// Create new vector and use it as a wrapper
// over Array argument:
var v = new Vector([1,2,3]);
// add(newElement, atPosition) method
// if no atPosition provided, newElement will
// be added to the top
v.add(4); // add 4 to the top
// Add 3.5 atPosition 3
// The element currently located at v[3] and all elements atop
// of it will be moved one position up
v.add(3.5, 3);
// remove(atPosition) method
// Elements currently located atop of it will be moved
// one position down
v.remove(1);
// toString method is overloaded so in string
// context it gives comma-separated vector values
alert(v); //1, 3, 3.5, 4

I want after send a comment, that message submit online and insert to database, Without Refresh Page. In this code, $.ajax function worked , but success: function(html) does not work(document.getElementById). I do not know why it does not work!? What do I do?
[Code]...
This may be a NOOB question and I am new to jquery itself so my syntax may just be incorrect but I do work with javascript and php quite a bit.Anyway here is a piece of sample code that is correct and does what is expected
[Code]...
From what I have read I believe the format is correct in my function. In PHP I have a print_r function that would dump an array where regular echo commands would simply output array so this may be a similar issue. I am not sure.
