I am trying to follow this article on doing a POST request with AJAX and PHP and it works fine, but as soon as I switch from the default submit button to an image I get an error. I would really appreciate any assistance on why switching the submit button to an image would affect it. Thanks http://www.hiteshagrawal.com/ajax/form-post-in-php-using-ajax/comment-pa...

How to submit a form using JQuery via AJAX to an ASP.NET and receive the response
The purpose of this article is to showcase how to submit a form to an ASP.NET Page via AJAX using JQuery. Why would we use AJAX to submit a form when developing an ASP.NET application? That is an application design question. However, if it has been decided that AJAX will be used, then JQuery can help you make your codebase smaller and also make the code cross-browser compliant. JQuery does a lot more and for that please feel free to refer to the JQuery sitejQuery ajax laod script does not load
Hi all,
First post. Lurked for a bit while learning and thanks for all the indirect help.
I am having trouble with jumping into ajax.
My old application is all php and I was trying to switch it to ajax for the users who have javascript so there is less page refreshing but also to keep the links working for those who don't or don't want the change.
here is a test files I've been working with:
Troubles When Developing With AJAX
For those that are not familiar with AJAX, the word is an acronym for Asynchronous JavaScript + XML. AJAX is not new to the scene. In fact, even the newest advances in AJAX are at least five years old. Yet AJAX is becoming the buzz word in developing. AJAX is a very powerful technology that allows you to build a website with incredible functionality without users having to refresh the web page they are on. However, there are some “bumps” in the road when trying to utilize AJAX.
MVC 2 - jQuery Validation and Form Submit - DataAnnotations
I have a sample application, trying to learn jQuery validation and submit form in this scenerio.
The page has one text box (EnvelopeID per class Envelope). If submit button is clicked and the text box is empty then i want to show an error message. If it is not empty then i want to post ajax request to GetData Action. The action returns partial views (value 1 or 2) or error string.
Problem:
1. Client validation is not happening here.
2. How can i make $(form).submit to adhere to jquery validation and not post the data if empty? I can check for text box being empty or not before posting (manually) but i want to use the proper way.
This same very example works with MSAjax and validation without any problem.
How the D7 AJAX framework could fall short of being spectacularly useful
With a title like that I should start by stating unequivocally that the D7 AJAX framework is a wonderful thing. Based on Earl Miles' CTools AJAX framework, it takes the agony out of dynamic form elements that characterised D6 AHAH forms, and I co-presented a session with Rob Loach and Randy Fay extolling its virtues at DrupalCon SF.regarding my post ajax question
