通过超链接提交表单

< script LANGUAGE = " JavaScript " >
2 function checkvalue()
3 {
4 if (document.welcomeform.nickname.value == "" )
5 {
6 alert( " 昵称不能为空！ " );
7 return ( false );
8 }
9 if (document.welcomeform.password.value == "" )
10 {
11 alert( " 密码不能为空！ " );
12 return ( false );
13 }
14 document.welcomeform.submit();
15 return ( true );
16 }
17 </ script >
18
19 < body >
20 < form name = " welcomeform " method = " post " action = " welcome.asp " >
21 < a href = " # " onclick = " javascript:checkvalue();return false: " > 登录 </ a >
22 </ form >
23 </ body >

第二种方法：

1<form name="welcomeform" method="post" action="welcome.asp">
2<input type=text>
3</form>
4<a href="javascript:welcomeform.submit();">提交</a>
