我们一一点击，就知道发现什么回事了。

隐藏域就不用说了，它肯定会提交。

submit按扭会携带其自身的name,value提交到后台，这样我们就可以少写一个隐藏域。

image按钮这里写不怎么规范，它其实还要一个src属性，指定一个图片，提交时，地址变成这样的：

http://localhost:8383/avalon/newhtml.html?bbb=eee&submit.x=7&submit.y=8&submit=yyy

image能提交你当时的点击位置，因此在早些年，可以防止机器人刷单刷评论！

如果button标签不指定type值，那么它会默认是submit，其效果与input[type=submit]相同！

reset按钮不会提交，因此没有反应。

此外，总结一下各种提交表单的方式：

点击input[type=submit]
点击input[type=image]
点击button[type=submit]
在文本域或密码域等可以填空的表单元素内回车！
