Error message does not refresh the page

Question

What can be done so that the page does not refresh after the error message is returned to ajax, but instead prompts for the error that needs to be corrected?

<p>Change the <button>submit label to<input type="botton"> and the page will not be refreshed. <br></p>
<p> In addition to the text prompt returned by the verification error, is there anything else? The data is returned. For example, if the name is wrong, return my name so that I can judge again, and then add </p> to the class on the input tag.
