A button can be of three types: submit reset or button. A click on a submit button sends the form's data to the web page defined by the action attribute of the element. A click on a reset button resets all the form widgets to their default value immediately. From a UX point of view this is considered bad practice. A click on a button button does... nothing! They useful to build custom buttons with JavaScript. Q - if there is a registration form design on javascript.does input type button can submit a form to server Ans - By default it will not submit the form but you can custom build it to send the form to the server Q - Ans - By default it will not check it but if you want to do it you'll have to create methods that check the user input. you can do it like function ValidatePage() { if (typeof (Page_ClientValidate) == 'function') { Page_ClientValidate(); } if (Page_IsValid) { // do something alert('Page is valid!'); } else { // do something else alert('Page is not valid!'); } } Please mark the solution as Accepted if it solves the purpose
