Button跳转方式

<input type="button" value="个人主页" onclick="javascript:window.open('http://172.16.16.5','_self')" />
onclick="javascript:window.navigate('....');"
或者
onclick="javascript:window.open('...', '_self');"
 

<input type="button" onclick="document.location='http://172.16.16.5'" value="个人主页" />
不是新窗口，是本页.

<script language=javascript>  
fuction open() {  
   window.location.href="xx.htm";  
}  
</script>  
<input type="submit" name="submit" onclick="open()">

<script   language=javascript>  
  fuction   open(){  
    if(!document.form_name.username.value)  
            {  
      alert("请输入用户名！");  
      document.form_name.username.focus();  
      return   false;  
            }else  
      document.form_name.action="xxx.htm";  
  }  
</script>  
<input   type="submit"   name="submit"   onclick="open()">
