I have a form with several submit buttons, two of which I will discuss. One is an Update button that allows elements of the form to be edited and submitted to be saved. It does not require all the information to be filled out but if certain elements are filled out, like a telephone number, it is validated.

Id does the validation okay and gives me the correct return value but it never actually submits the form. Part of my problem is the way the calls are being processed by javascript and unless I string them together inside one another they just process is whatever order happens.

In my case it is important that they process in order. The other problem still there is that form. So I will try a click type of event rather than submit and see if that helps. I would still like to get any feedback regarding this if anyone cares to chime in.

Or is it just listening for the form to submit and then you tell it what to do? If it is the latter, how do I get the form to submit since I have to use e. Again, I want to handle this more on a procedural level but have yet to find a way to control the sequencing of events and functions.

Thanks for the input and that is the way I would expect it to work. I swear I have tried that but will try again in the morning to be sure. One other thing and thus may be causing part of the problem. In the validations I make an Ajax call to the server.

Had to try it tonight so I can sleep. Here is the actual code that is running. The first part checks to see if it is blank. If it is, it works as expected and the js handles the validation and the messaging, the form never gets submitted. The second part checks in the db to see if the name exists on another document. If it does, it returns false so the click should be rejected.

The form is being submitted and the message that I am getting is the one generated on validation on the php side. Of that I am sure. So it appears that even though async is false, it is bypassing the return of the ajax and just moving on to submit the form. Unless I am missing something completely, which is entirely possible also. You have a e. In fact since both if branches call the preventDefault you only need it once at the top. So this:. If you put the e. The idea is that if it passes the first validation testing for a blank value and then goes through the ajax validation which queries the database to see if the name already exists, then I want to let the click process.

And on my full example the first validation works fine. If the field is blank, the preventDefault works just fine and the validation is handled by the js code. The problem comes in the. And that is the same whether asynch is true or false.

It sounds like you are using the wrong event in this case. If you are wanting to control whether the form is submitted or not, it really needs to be the submit event from which you do that. No, it behaves exactly the same way as with submit. And to be sure, I just tested it again.Last post Apr 08, AM by bolla1.

Hi, I have a problem where if a form submission set up to submit via AJAX fails validation, the next time the form is submitted, it doubles the number of post requests - which is definitely not what I want to happen. I'm using the jQuery ValidationEngine plugin to submit forms and bind validation messages to my fields. This is my code below. I think my problem is that I need to unbind from the validationEngine plugin when the form fails, but I can't figure out how to do this.

Use class selector instead, or try this:. I also had the same problem. I also had tried what you had tried. Then I change my method not to use jquery but by using "onsubmit" attribute in the form tag. But, when I tried to put the false return value only in "thefunction ", it doesn't prevent the submitting process, so I must put "return false;" in onsubmit attribute.

So, I conclude that my form application cannot get the return value from Javascript function. I don't have any idea about it. Attach the event to the submit element not to the form element.
