Call Parent Method - Creating A Job Ticket Object That Will Interact With A Database
Nov 2, 2011
I 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 have defined a method in an iframe named as refresh1().In the iframe we are showing records in a table.on clicking a record of table or you can say row a showmodal Dialog object will open which shows the info of clicked record.I want to call refresh1() method onclick of save button whic is defined in modal dialog.I have triedparent.window.dialogArguments.refresh1() but it is not workin.
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 have the following issue - if a user select 'select box' as a value in a drop-down list, a new window is opened where they can enter values then they should click on a button and a text thay have typed should pass to a hidden field in the parent window.
How do I do this? I tried this (child window)
<html> <head> <title>Values</title> </head> <body BgColor = "#FFFFFF"> <form name = "f1"> <textarea name = "ta"></textarea><br /> <input type = "button" value = "Ok" onClick = "getValues ();" /> </form> <script language = "JavaScript"> function getValues () { window.alert ( document.f1.ta.value ); parent.aff.vals.value = document.f1.ta.value; } </script> </body> </html>
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.
Does anyone know if this is possible to have a online database? Or can I use access to make a database and then post it online and have it work on the internet?
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;
Code:
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 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'".

could someone please point me in the right direction for creating an AJAX page that displays "live" data from a mysql database? I need the page to update its self every time data changes in a mysql table.
I too have a problem with Ajax POST method and Send. I have set up a Site Search using the Google Ajax Search API, and it works fine. The search term is stored in the variable (?) query. Just to make sure, I have set up a new variable (searchTerm) to read the value of query, and a temporary Alert box shows that this variable does indeed contain the search term.
I want to store the search terms in a database so I can see what people are searching for. So I set up a POST method to send the searchTerm to a php file, which uses if (isset($_POST['searchTerm'])) to obtain the searchTerm and then insert it into a MYSQL database. But it doesn't work.
When I couldn't insert into the database, I added a second (temporary) insert using a dummy value as the else part of the above if statement, to test (1) if the Ajax file was actually setting the php file going, and (2) to check my Insert code was working. Both work.
So the problem is clearly that either the Ajax code doesn't Send correctly, or the php isn't receiving it. I am stumped to find what is wrong. Here are the two relevant sections of code:

To repeat, the php is running and always loads the dummy variable from the else section, indicating that isset($_POST['searchTerm']) is null.
Can I call a value from the database to javascript/vbscript. Let's say the database is called SQL="SELECT * from checkout".Can I validate that the SQL and the javascript/vbscript equals to each other and inside the javascript uses the response.redirect function to another asp page?
This hides the games the user doesnt want to see on the page. But before the game is hidden I want to make an Ajax call to the database and add the user's preference into the table so next time the user comes to the page I can hide the game from the start. How can I do this?
I have a js file located on domain A, and on domain B i have included the js file, i want to change some information within my js file depending on the url(pulled from a database). I already have pulled the url via some coding and I am wondering if I use Ajax on domain B will this actually pull the information or will it stop it because of cross domain security? If it will block it, how can I pull this off?

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?
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:
