<form name="vip_login" method="post" action="la.php">                         href="#" class="loginbtn">submit</a> </form> 

how can make button submit above form?

<a href="#" onclick="return false;">loading</a> <a href="#" onclick="return false;"><span class="vip"></span>submit</a> 

add id form , button (or link), example id="my_form" & id="my_btn", can submit form when link clicked this:

<!-- code should placed anywhere after form--> <script> document.getelementbyid("my_btn").onclick = function () {     document.getelementbyid("my_form").submit();     return false; } </script>
