注意：get方式提交表单时 action里面不能用url传值, post则可以这样传
js提交和submit按钮提交的区别:
1. js提交表单时不会带上 submit 按钮的值(因为没有被单击) 所有浏览器
2. input 回车提交 w3c浏览器会带上submit按钮的值，ie6则不会带
解决办法：增加一个hidden域,用这个来判断，无论用哪种方式提交都会有值
submit按钮上绑定提交事件:
即:<input type="submit" name="btn" value="btn" onclick="test()" />
都会带上submit的值, 用js提交都检测不到onsubmit状态
w3c： 提交一次
ie6: 分两次提交，先js在form提交
解决办法：如果按钮为submit则 检测时用onsubmit事件检测
如果按钮为button，则检测通过后在触发submit事件
一定不要用js提交表单，然后又用onsubmit去检测
单纯的用js提交表单, alert, ff下阻塞表单的提交，而其他浏览
