<input type = "button" ></input> and <button></button> differences in MVC

All morning today, in the form form in MVC3, put a <button></button> trigger the OnClick event in the button, although there is no submit but will still submit the form (submit address is the default address is sent over the general Controllername/index) and <input type= "button" ></input> will not

Inadvertently put the <button> tag in the <form> tag, you will find that clicking on this button becomes a commit, equivalent to <inputtype= "Submit"/>

The default type of Internet Explorer is "button", while the default value for other browsers, including the specifications, is "submit".
