View 2 Replies View RelatedI am creating a job ticket object that will interact with a database. It has to update the database on the fly via AJAX. Within the job ticket object, I have instances of a Component Object. Within the Component Object, I have an instance of an Editor Object. One of the methods of the Editor object is a function to edit some text and when it's submitted, it will update the database. All of that is working fine. My problem is that I need to refresh the screen with the new contents of the database. I have a method in the Component Object that refreshes the screen, but how do I call it from within the Editor Object? I believe it has to be called there because the editor object has a handler for the form submission and the AJAX function. So I'll have to reference a callback function once the AJAX request is handled, but I don't know how to call it.
I know that sounds kind of convoluted, so hopefully, this very simplified code will paint a better picture of what I'm trying to do:
Code:
Now I want to call refreshScreen, but I don't know how:
I am creating an application that uses as much Object Oriented code as I could (mostly to learn it).
I have an object called 'photo' that contains two Image() objects 'fullImage' and 'thumbnail'. All is fine and dandy, I can read the thumbnail and the full image, and their associated properties just fine.
But what I can't seem to do is make the thumbnail's onclick event refer to one of the object's methods.
Here is a greatly simplified version of the object's code.
Code:
So, the thumbnails div gets populated with the thumbnails fine. But for the life of me, I cannot figure out how to make the onclick call the photo object's "editPhoto" method.
Will the way that I am creating the objects using the same name for each one, result in only the last one created being accessible. If so, do I need to create an array of objects so I can uniquely identify each one?
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()});
I have two methods and I would like to call somename1 method from within somename2 method. I have tried several ways to do so however I keep getting "TypeError" or "RefernceError" I have tried several ways to reference but I am still unable. What am I doing wrong. I would think this would be easy to do.

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;

I just got this script for a countdown on a website and I got it to work locally but when I upload it to the server i get the error "index.html:22 Uncaught TypeError: Object [object Object] has no method 'fancycountdown'".

I have a Class name Merkzettel.

and addClickEvent sets the onclick attribute of above mentioned DIV. and in addClickEvent I am explicitely mentioning the name of class object. This means every time I create a Variable with another name I have to Change this function also.
I attempted to invoke a C# method using jQuery but it failed. The reason is because the method cannot be found. However the method exist in the class. Did I miss something?
View 4 Replies View RelatedI have been wondering if there is a way to make the following javascript functions work in IE8 and Chrome:
var funct = function()
{
var ppt = new java.awt.Point(200,100);
alert(ppt.x);
}
This thing works only in Firefox. Is there a way to enable global Java packages in IE 8 and Chrome?
I'm trying to use the ajax load() method to load a file from a parent directory, e.g.
$("#divTests").load("../tests.htm");
But that doesn't work. I can load a simple html file from the same directory as my html file or a descendant directory, but not an ancestor directory. Nor can I load from an external server.
I'm doing my testing on my PC and I'm not running a server (apache or otherwise). Just using it as a simple client. Is that possibly the problem? Or is there something else I'm missing? If that is the problem, is there a workaround?
I am trying to call a java method from within my Javascript, but cannot
seem to get it to work. All the examples I have found online and in
the forums are using Java applets. I have a method that I want to call
that does a search, and produces a message dialog displaying the
results. Also, the class file lives next to the html file. How would
I invoke this in my code? This is what I have now:
<script>
function searchStrings(){
Searcher.search();
}
</script>
<form>
<input type="button" value="Search" onclick=searchStrings()>
</form>

I have this javascript code which I would like to call the refresh method in my init function but I can't seems to be able to call it. What is the proper way of doing this?
PHP Code:
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 the following code in one of my pages. My problem is caused, because the method "processEvent" is never called, but I have no idea why. I guess it is broken, because I don't relay the "this" object correctly.

this.init = function()
