View 3 RepliesI'm using jquery to make it easy for AJAX calls.
So I create a class: function cMap(mapID){//vars and stuff}
I go and prototype a function: cMap.prototype.loadMap = function(){ //jquery AJAX call }
Now in the jquery $.ajax({...}); call, I use an anonymous function on the "success:" call: success: function(data){ this.member = data; }
My problem is that inside this anonymous function call I'm trying to call a class member of my cMap class to store the data in from the AJAX call, but it's out of scope. So the JS console in FF/Chrome throws errors about bad value/doesn't exist.
How can I access this class member from inside an anonymous function? Or at least what's a good way to go about doing all this?

I already have a PHP function (in a class) that retrieves the provinces/states from the database based on the country. I was wondering if it was possible to call this function instead of having to make a new file (in this case FindProvinces.php) that calls the function.
Just getting my feet wet with AJAX and trying to figure out how I can make a javascript call to a specific PHP function in another file when I have a drop down menu change value using DOM. I've found lots of examples of how it could be done with GET variables, but none for this particular method of data retrieval. Has anyone ever ran into this, and if so, how did you solve this interesting deliema?

So this comes down to finding away to fire the javascript function only after the JQuery function has finished updating the HTML property of the DIV tag. I'm having a similar problem with a .post() command, and I expect whatever the solution is to this problem can be used to resolve the other as well.
Clearly I am invoking this wrong.

At the moment I have a link in a div that targets an ASP page to remove an item from the database.
<a class="small" href="/products.asp?Action=RemoveProduct&ID=<%=(rsCartItems.Fields.Item("ID").Value)%>">remove</a>
What I could like to do is use JQuery .click and .ajaxmethods but the only thing I am unsure of is hot to get the ID of the a href tag containing the unique item ID that relates to the db record. Can I use this.id?
<script>
$(document).ready(function
(){
$(".removecartitem"

I am trying to track progress of a database operation . and want to display percentage progress on page asynchronously.
Process.jsp - In this i used javascript to call ajax function continuously which returns percentage progress. My Code is ...
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();
}
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() {

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?
On a project I got stuck on this "problem". When you make a json (ajax) call. You also need a callback function. Which means I have to call the next $.getJSON within that callback function to read the next portion of data. In my opinion this is not very readable code...What I want is a nice and readable piece of code. Where you could just write it like this:
var data1 = $.getJSON(..);
var data2 =$.getJSON(..);
I've found a solution here: [URL] (explains my problem perfectly). But it's not compatible with the getJSON story. Is there already a possibility to do this with the jquery library?
I am having a problem of calling the user defined JS function after I make the AJAX call. Basically, I created couple radio buttons on the main html page. When the user clicks on one of the radio button, it will trigger the AJAX call and return another html file in the "div" content that I set in the main html page. The other html file contains a user defined JS function (e.g. "updateContent()") which use the onclick event handler to call the function. When I'm running the app, and click on the button. I had seen the firebug was complaining the "updateContent() is not defined" error. The function itself works fine and must be defined properly.
Here is the code in the main.html page:
Code:
<script type="text/javascript">
var asyncRequest;
function getTools(url){

I am trying to get a form to call a javascript function on submit to send an ajax request. The site sits on one server and the php target file on another. I get a status of 0. From what I read, this is because the php file sits on a different server. I do don't believe I can get around the files sitting on different servers.I can set the php file as the form action, but I do not want to redirect, just send a request to the other server to modify some values in a DB. If I can not send an ajax request between servers, I was thinking an alternative might be to set the php file as the form action, run the updates, and then have the page redirect me back. Is there a better way to get around this problem
