Google Chrome warnings. How to deal with themm

Ellis · July 14, 2025, 2:27pm

Hello All. I have been trying to run an application but I’m receiving many Google Chrome warnings and errors. I have searched on the forum but I have not found how to deal with them.
Some of these warnings are:

[DOM] Password field is not contained in a form: (More info: https://goo.gl/9p2vKq) <input id="txtPass" type="password" name autocorrect="off" autocomplete="off" autocapitalize="off" step="any" value placeholder="Digite el password" data-nsb-type="TextBox_jqm" required style="text-shadow:none;" class=" ui-mini  ">

Have you seen any of these? What has to be done to solve this?

Thanks a lot in advance.

These warnings are mostly about the IScroll library, but I’m not sure how you made them happen.

Can you create a minimal project (hopefully with just one control) which reproduces this problem?

Thanks a lot for your reply George. I saw about the JQM framework and tried to use FrameWork Converter but got this error message:

Anyway, I’m sending you the project so you can see if there is something in it that makes the converter show this message.

Any help will be much appreciated.

Thanks a lot in advance,
