I am trying to access my own JS object from within an ajax call, and can't figure out how to get it to work Whenever I access "this" in the function, it returns the ajax context and not my JS object context. My code looks something like this. I have a Zone object defined in a JS file like this:

I am getting an error to a mysql_query() call: Access denied for user 'SYSTEM'@'localhost' (using password: NO)' in path 'C:PHPClassesMySQLDbClass.php' at line 1078 This is coming from using a XML HTTP Request object (AJAX) to send form data to the server requesting my DB records interface script page, ajaxRecordsInterface.php. In using PHP sessions, I have no problem going from a logged-in-select-activity PHP document to an activity controlled by a PHP document that does records interface. But apparently an XML HTTP Request object has a different session than a PHPdoc-2-PHPdoc session. Is that so?
Here is MORE DETAIL: I am building first a version of a web-based database interaction using MySQL that does not use page reloads, so that means I am using Ajax/XML HTTP request object/Javascript (later I build the version that does script-free page reloads to show db updates/refreshes). I have no problem with login whose first PHP document gets user information and presents it, as well as a menu of links to how to interact with the DB. One of the options is to add/edit/delete student records.
In the PHP document which is the DB records interface, I have a scrollable HTML table at the document top with one table row for each record. Below it is an empty form, whose fields get populated when the user clicking on a record in a table row. Note that all fields for the records in the table rows were delivered as a Javascript array with a maximum of 50 or a 100 contiguous records in the MySQL table. (More optimizations may be done later, such as creating a Javascript array as a "cache" of the last 20 or so selected records.) I don't have problems making mysql_query() calls in a series of PHP document requests. I call session_start() to get session variables, one of which is a serialized MySQLDatabase class object which I unserialize to get the object again. The problem is the XML HTTP Request to a PHP document designed to interact with it is a different PHP session from a page-to-page session.

My problem is that whenever I make the following AJAX call, I get an "Access to restricted URI denied" error on Firefox. On Internet Explorer I have other problems, but I can tell by my server logs that at least the AJAX call happens, which is more than I can say for Firefox. code...
The url is correct, and the server is hosted on this machine, but Firefox thinks it's trying access another domain. The html file containing this code is located on my hard drive.
How can I get Firefox to allow this AJAX call?

I am trying some simple things with javascript and trying to use it in a object oriented way. However I am now facing a problem in which I can't access an object variable from an object method. I am using jQuery.
My code is as follows;

My problem is that the variable msg1 does not work when accessed from function called from the jQuery get function. I get the message undefined. Therefore I am wondering, is there a way how I can access msg1 of my object instance from the get function of jQuery?
I have UL tag:
<ul id='ul'>
<li id='li1' class='someclass'>
li1</li>
<li id='li2' class='someclass'>
[Code]....
Now we have alerts only for three old elements. This is clear. Because these elementes have been initiated before page generated. But the new one is ignored.
The question is - how i can add new elements to the UL list? It would be glad if "jQuery.each" could read four and more elements - not just the first three initiated elements.
i have function appended to a click event of more than one objects. How can i check if the object that was clicked has a certain class xy?

I've created an object with properties and methods. The object is associated with a form. The object iterates through the form and finds any inputs that are required. It then uses each to apply validation to each of the found inputs. From within each(), I need to access properties and methods of the parent object, but now this refers to the current collection object. How do I access the containing object?
View 1 Replies View RelatedIf "this" inside of a sortable "receive" function refers to the receiving object, How do I access the object to which the receive function belongs?
Example:
// Function that takes a JQ object and makes it sortable.
// We assign the "SortableRecieve" method to the receive event
MyObject.prototype.MakeSortable = function(JQOBJ){
JQOBJ.sortable({
receive: this.SortableRecieve

MyObject.prototype.DoSomething = function(){
// Does something important

// The actual function that gets called when the receive event occurs
MyObject.prototype.SortableRecieve = function(event, ui){
// This function call won't work, because "this"
// doesn't point to the right thing!
this.DoSomething();

So how can I access the "True" this that refers to the object?
I have very simple question (ie probably simple for everyone with jQuery experience, but not for me). Lets say I have the following list

sorry but how to access text field with $() ??
<form name="mainForm">
<input type="text" id="testField" name="testField">

so instead of document.mainForm.testField.value, with jQuery, is it $('#testField').value ??? i know $('#testField').value doesn't work
The general framework is a simple user login function. The user name is selected and a password entered as usual. The function grabs the element values and passes them to a php page that queries the database. An AJAX call returns the password to the function and then I want the innerHTML to be a choice of two web pages, depending on success or failure of validation. There are existing AJAX functions available on the internet but they are overly complicated for what I think should be a simple, quick to load function.
Where I am stuck is that the standard procedure to make an AJAX call is the browser window event. How do you make the call from within the function? I have tried creating two new variables, "success" and "again" to replace xmlhttp, but still stumble on the event to assign a value. I left the blank password protection (if statement) with that variable to demonstrate what I mean.
I've put in my code below, which is in development and successfully alters the innerHTML text depending on user input but I can't figure out how to insert the relevant php page. I have '// out' the testing bits, but left them for info. (I have tried full 'scripting' as the innerHTML, but it's messy.)
how can I detect if mouse cursor is over or out of some element? I am running a animation, which I don't want to run or to stop itself if cursor gets to area.

I found very difficult to call a method outside his scope.For example I have 2 files js
myFunction.js
init.js (where I initialize all my page)
[init.js ][code]....
I tried many syntax in order to call the method outside its scope
$.getX();
$(function(){getX()});
$().function().getX();
$("myHtmlObj").click(function(){getX()});
The answer to my question is probably very simple, but I'm having trouble making this work.

I have 95 different objects like this one:
obj1Object = {
name: "some name",
type: "type",
picid: "001",
maxvl: 500000,
minvl: 5000,
clsid: 1,
movable: true,
size: [45, 45],
note: "Some text here"

Now what I need is to access these objects only when I need then. Right now they all load when accessing my program so all 95 of them are "somewhere" in memory.

I want to access the features of a plugin without actually embedding
it into a page. Is this possible? Eg
The code to embed the object into a page is:
<OBJECT classid='CLSID:7FA62735-AHC3-14d2-9F81-00114B3245C5
codebase='http://www.test.com/plug.cab#version=3,1' "id='myPlugin'
height=Ɔ' width=Ɔ'>
<EMBED type='application/x-myPlugin' name='myPlugin' hidden='true'
src='in.txt'></EMBED>
</OBJECT>
I could simply add this using document.write, but for various reasons
I dont want to do this.
I would rather do something like:
var plugin = (navigator.mimeTypes &&
navigator.mimeTypes["application/x-Web-Plugin"]) ?
navigator.mimeTypes["application/x-Web-Plugin"].enabledPlugin : 0;
myObj = new object("CLSID:7FA62735-AHC3-14d2-9F81-00114B3245C5");
