dynamic_form

I'm trying to create a dynamic form so I used the idea of using a listview builder to create it. I was able to successfully create it but I faced that I cannot discard changes made to the form by popping it off after editing it. The two textFormField Job name and rate per hour were able to discard changes as they were using onsaved but on the checkbox I can't do that as it has onChanged which wraps setstate to change its state.

You can take a look at the video at this link to see how it functions as of now - https://vimeo.com/523847256

As you can see that it is retaining the data even after popping the page and coming back which I don't want it to. I'm looking for a way to prevent that and make the form the same as before if the user didn't press save.

I have tried to reassign the variables() in onpressed of back button but that didn't work. I also tried push replacement to the same page to reset it but that also didn't work. I think the cuprit here is the sublist and the initialValueTextFormField and initialValueCheckbox which are used declared under ListView.builder but I don't know how to fix that without affecting the dynamic list functionality.

The value entered in field "term" arrives to test.php but values in fields "AttrName" and "Attribute" does not, even without adding any more fields, addition of more fields works, but values are not sent.

Working on learning JavaScript. I am working on creating a dynamic form and displaying the output. Below is a simple example. If I step through the script using the debugger tools: a)the form loads, b) the form takes an input c) the message displays d) the message disappears. I can't figure out how to get the message to persist. Thanks in advance for any help.

JavaScript

Within Zeppelin, a jdbc paragraph can be parameterized to query according to input from a select form (dropdown) e.g.

I'm new beginning, I'm writing a script using PHP, jquery. on of the forms I'm developing is to allow the users to add several records to one table. that was fine. my issue, I need to replicate the value of subSerId to other fields of the added rows once clientname updated, I can do it for the first two records but after that it will not work.

as you can see through the following picture, I looking for away when I update the client name field, the value of Service ID will be changed. I can have this happen for the first and second rows (parent) but not for the third.

And here is the jquery script
