如何使用mailto？
1）基本用法
<a href=mailto:sample@163.com>send email</a>
或者
<form action="mailto:sample@163.com"> </form>mailto后跟的是收信人。
可使用参数列表
to 收信人
suject 主题
cc 抄送
bcc 暗抄送
body 内容
参数传递方式同页面之间传递值一样，可以使用查询字符串，也可以用form
querystring方式：
<a href="mailto:sample@163.com?subject=test&cc=sample@hotmail.com&body=use mailto sample">send mail</a>
form方式
<form name='sendmail' action='mailto:sample@163.com'> <input name='cc' type='text' value='sample@hotmail.com'> <input name='subject' type='text' value='test'> <input name='body' type='text' value='use mailto sample'> </form>两种方式同样传递所有参数。
