Topic: select-wrapper duplicates in itself after reloading mdb for a new ajax form

gianlucagiacometti priority asked 1 year ago

I load a new form via ajax in a modal or in a section of the page. I need to reload the mdb.min.js for the form to show properly.When I reload mdb.js if there are select fields in some other parts of the page they duplicate and a new select-wrapper appears inside the previous one.

*Expected behavior*The existing select fields in existing forms should remain unaltered

*Actual behavior*The select field duplicates the select-wrapper

** Suggestion/Feature Request**If the input fields could be initialised by javascript API like for select, a programmer could initialise each single field without the need to reload the mdb.js

Thank you for any suggestions

I had the same Problem and had a proper solution with 4.3 with this code:

document.querySelectorAll('.select').forEach((selectInstance) => {
  if(selectInstance.parentElement.className != 'select-wrapper')
     new mdb.Select(selectInstance);

With 7.2 i now get an "Illegal Invoking"-Error.

You should use the getOrCreateInstance method. Here is a snippet with example:

I got the same problem, The existing form on the page select fields duplicated when i load a page into a div. Any solution?

Edit, I manage to figure it out with the api

There shouldn't be a need to reload mdb.min.js. If you have form in modal the best way for it to work is to create it after the modal is shown. Because elements need to exist and be visible(f.e. meaning they cannot be hidden in accordion) to be initalized.

Thank you. You are right if the modal is already loaded in the page.I add the modal dynamically with ajax and inject it after a click on a button. That is why I have to reload content of the modal form changes according to the situation. That's why I am using ajax

Do you need further help?

gianlucagiacometti priority commented 1 year ago

Yes please,I must inject the form into the page after the first load of mdb.js.After the injection I have to reload mdb.js otherwise the form fields do not behave properly. There seems to be no other ways. Doing so, the already existing select fields duplicate.I suppose there's a bug on select. It should not duplicate if I reload mdb.js.May I hope in a bug fix?For the moment I will try to destroy the added select on the fly. Another appreciated solution would be to provide an API for the 'input' fields so that I can initialise them without reloading mdb.js
