Solve the explanation of action='#' in the form tag_html/css_WEB-ITnose

form action #

I am a newbie. I encountered a little doubt when doing exercises today: action="#" appears in the form tag. Usually I only know that action is followed by the action name. Please explain the meaning and usage of action="#", thank you very much!

Submit data to this page
Under what circumstances should it be better to submit to this page, and under what circumstances can you only jump to another page. What is the difference between the two?

There is no difference, this It depends on who accepts the data in the form. If the current url is accepted, the action does not need to be written or action="#" or action="current url". If b is accepted, just write action=b

Many people arrive at the current address in advance because I have made a form memory. For example, if the content of the form data does not meet the requirements, the data just filled in will be reproduced in the form to facilitate modification. If it is submitted to another address, it will have to be returned again

Thank you for your advice. , as you said, some input content in the form has format verification

I understand. Thank you for the explanation

If it is only client-side js verification, there will be no server-side verification. Nothing to think about

I see, let’s see if my understanding is correct. The input content needs to be verified in the format defined in the framework, which is done on the server side. That’s why you need to submit it to this page. method (or is this the only method?). If it is just Js verification, those form data can be passed directly to the next page. is that so?

Yes.
If the input data is verified on the server, the attribute value of the action is not the current file name. It is also possible to implement form memory.
