server validation without reloading the page?

server validation without reloading the page?

Hello all,
I have a form where the user enters a code.
This code must match a code that is present in a specific table.
So, I will create a recordset that will filter the "codes table" based on the form "code field". If the recordset match the entered code, validation should pass.
But is there a way to instantly display a checkmark if validation passes without submitting the form? (I know this can be done with ajax alone, but is there a way to do this with webassist tools?
TIA
tony

You can use "Load Plugin From Div" to do an AJAX post and display a result. It is identical to the concept in this tutorial: http://www.webassist.com/tutorials/Dynamic-Dropdowns-with-Data-Bridge-2-0

The only difference is that your plugin shows an error message (or no error) based on the input field on the first page instead of showing a second filtered dropdown list.

This is something I could help with in a premier support ticket.

Hello Ray,
this is what I was searching for.
I followed the tutorial and it almost work.
This works until I trigger the plug-in.
If I don't trigger the plug-in the form submits.
If I trigger the plug-in (with the onKeyUp behaviour) the submit button doesn't work any more.
What can I do to make this work?
I'm using Data Bridge 1.
TIA

Please post a URL where I can see the problem and give me FTP access. I'll take a look and see what is going on.

I'll need FTP access as well to debug this properly.

Since you are doing form validation and using the progress bar, you need to set the value of MM.returnValue to true or false to identify if the form can be submitted or not. I've added a function for that and the page appears to work properly now... see lines 273-275 and the lines that reference framework_load_plugin_url to see the changes I had to make.

Hello Ray,
thanks for your help.
Since the problem is the progress bar I would remove it. Iis there a valid alternative to it? Example: disable the submit button until the form is submitted?
TIA

At long last I think to remove the framework plug-in.
Too bad, it was a good idea to validate the voucher code in real time.
But it's a bit difficult to tweak the code (for me) to make it work along with the progress bar.
Your example is working but it will allow the form to submit only if the voucher code is validated. I need to submit the form even if the voucher don't pass the validation (I will apply server validation (as usual) to this field (using a recordset that will verify the voucher code).

Is there a simpler alternative that will check a form field in real time using a recordset?
TIA again.
tony
