Ajax :: Function Directed To Same Page Not Working?
Aug 23, 2010
I have a dropdown menu and i want it to be populated based on certain values of other dropdown menus. I'm therefore using ajax to send the values of the other form elements to the server based on the onchange event of the other dropdown menus. I have written a function in my js file that sends the values to the server using ajax and the request is sent to the same page (php file) that is supposed to receive and use the values. Thus a portion of the page sends the request to itself and another is supposed to receive the values of the request ad use them. I realize the values don't get sent at all and the onreadystatechange function returns the html and js content of this php page as its response text.
Here is the code for the js file
function fac_sem_lev(fac_arg,sem_arg,lev_arg)
{
get the selected indices to be used to find the selected items
var f=document.getElementById(fac_arg).selectedIndex;
var s=document.getElementById(sem_arg).selectedIndex;
[Code].....

I have the following code:
$(document).ready(function(){
$('#link').click(function() {
alert('Clicked!');
$('#content').load('dialogs/load/content', function() {});
});
});
The link is a normal link that is not dynamically created. The alert works. I know the problem is not the Ajax call because this works just fine:
$(document).ready(function(){
$('#content').load('dialogs/load/content', function() {});
$('#link').click(function() {
[Code]....
It only breaks when located inside the click handler. It does not return response headers or a response. Is there something about event handlers and ajax that I'm missing?

big fan -- first time poster. I've been learning javascript and jquery on the fly so bear with me if I seem to lack understanding of what may be semantic basics.
Anyway, I'm building a mobile app using phonegap. One page grabs data for a table from ajax, and each table element has a delete button in one of the cells. In short: the clicks aren't working. I put the alert in to test, and no dice. I'm not asking for help on the internals, I'm just stumped on why the function isn't being activated,

I have this code in a function.
[Code]...
Alert 1 is to check if the program enters the function. And it does in all browsers. But when it comes to alert 2, Firefox does not execute the alert. So I assume there is something wrong with firefox executing the onreadystatechange. By the way this is the code for initAjaxObject()

I have several ajax calls that originates from the same page its updating. It works perfectly in firefox but in IE it works for about 18 requests and then just stops until the page is refreshed. I thought it was a cashe issue but I have added a variable for that. I think it may have something to do with binding but I am not sure how to sort that. This is one of my functions.

I am not a guru jquery coder and still have to learn alot, recently while learning jquery AJAX I have bumped into a weired issue, I have a apge right and in this page I have a dropdown list for people to select an RSS channel that they wish to know more about, the dropdownlist ahs an onChange event which when triggered it will get the value of the selected item in teh dropdownlist and post it to the other 'mini' pages that load on the same page via AJAX by using the GET method - ie: im passing the parameters like a normal querystring would. The problem is that when I assign the dropdown value to a variable called dropdown in the following line of code "var dropdown =document.getElementById('ddlChannelSelect');" it works in IE but not in the other browsers, I have debbugged this in FireBug and it seems that the variable dropdownlist is not actually getting the value of the actual dropdownlist nad it says 'null' or sometimes 'undefined'. Am I doing something wrong ? why is it that it is working in IE but not in other browsers ? can you pls give me a solution with some examples ?

I wrote this small page and for some reason when I click on the submit nothing happens (checked on firebug, no submit is happening)
<html><head>
<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
<script type="text/javascript">
$('form#login').submit(function() {
$.ajax({
type: 'POST',
url: '[URL]',
data: this.html(data),
success: success,
dataType: dataType
})});
</script>
</head><body>
<form action="#" id="login">
<input type="textbox" id="UserName" value="user">
<input type="textbox" id="Password" value="password">
<input type="submit" value="submit">
</form></body></html>

I have this code below:
Code:
$('#admintable').load("/includes/ajax.php?type=gallery&action=order&var=" + $.tableDnD.serialize());
The problem is that throughout my php project it calls different classes and definitions based on what modules are loaded.Is it possible to get it to load a function that is predefined rather than executing a page that will require me to once again declare all my variables and classes so I can perform just a simple db search.

can anyone direct me to some decent code that would allow "page a" to have a "login" (text) box, and based on what someone typed (i.e. "user x") they were directed to a different page?
user x => page x
user f => page f
etc.

Trying to call the same Ajax function twice on initial load of the page, but only the second one executed. I try to load mainpage, and inside mainpage I try to use ajax to load content1.asp to div1 and content2.asp to div2.
Test scenario (based on the Situation below):
- Page loaded, 1st ajax function skipped, 2nd ajax function loaded
- Remarked 1st ajax function, then 2nd ajax function loaded
- Remarked 2nd ajax function, then 1st ajax function loaded
- Moved the 2nd ajax function to above 1st ajax function, the 2nd ajax function is skipped.
Conclusion:
- the 1st ajax function always skipped. But Why? How to ensure both ajax is called upon loading of the page?
Situation:
mainpage.asp
<div id="div1"></div>
<div id="div2"></div>
<script language="JavaScript1.2">
ajax('div1', 'GET', 'page1.asp');
ajax('div2', 'GET', 'page2.asp');
</script>
ajax.js -
function ajax(strDivID, strMethod, strURL){
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById(strDivID).innerHTML=xmlhttp.responseText;
}}
xmlhttp.open(strMethod,strURL,true);
if (strMethod="POST"){
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
}xmlhttp.send();
}

Im using keyup function to track text typed in input box. The idea is to perform incremental search in db. This works fine. After this I update the html dynamically to display the filtered resuts and at the same time I must dynamically rewrite the html for input box code. After this the keyup function is not working anymore, allthough the id tag is the same? How should I get around this?
$('#filterBox').keyup(function() {
$('#status').text(this.value.length)
if (this.value.length > 2) {
filter($.trim(this.value));
}
});

This code works to insert a MySQL record to a Database using AJAX. It works fine on IE, but it's not working on FF or Chrome. When I test it on FF/Chrome, i just get the text "Just a second..." and it doesn't advance from there.

I'm creating an AJAX page that is built using a PHP Class, ie the php looks a bit like this: PHP Code:
$wp_page->addjs('../var/savepolicies.js')
$wp_parser->page = "userpolicywindow.php";
$wp_parser->addlink("Home","../index.php","");
$wp_parser->addlink("Logout","javascript:logout();","");
$wp_parser->getpageid("501");
[Code]...
within this page that has been created, there is an AJAX tree folder which calls another page to be loaded into a DIV by AJAX again. Code:
[Code]...
I don't know why it doesn't work because the page has been loaded with the JS file, but as soon as the link is added afterwards it doesn't work. I take it this is because it doesn't know where to find the JS, but how can I overcome this?

I have the following bit of jQuery:
Code:
$("#save_photos_all_continue").click(function() {
event.preventDefault();
var $black_white_all = $("#black_white_all").is(':checked');
var $color_all = $("#color_all").is(':checked');
var $other_all = $("#other_all").is(':checked');
[Code]...
In Google Chrome it works fine but in Mozilla/5.0 it actually goes to the save_edits page instead of just using the post and staying on the original page.

Im doing an Ajax call which calls a Java struts 2 action. This action basically just does a DB update. There is no data being returned to the client. The page refreshes to a blank white page. I dont want his to happen. I want a pop up box on my page. The ajax call happens when i press a save button. Here is the jquery code:
[Code]...
Im a Jquery newbie. As far as I can gather JQuery is expecting data back. It gets nothing back (which is what I want). But Jquery does a refresh with this. Hence why my page goes to a blank white page. I think this is what is happening
I was thinking of putting in my dummy div and loading the blank/empty no html into the dummy div but there has to be a way to stop the white page showing up. I dont get pop up boxes either as shown in code above:

Goal 1: display errors above the form on same page
Goal 2: direct users to a new thankyou page when form is submitted.
The form uses ajax. I am able to get it to work with the error messages displaying correctly but as is, the thankyou message also displays in the same spot and the form is left filled out. I need it to direct to a new page I designed for the purpose.
