Asp.Mvc 2.0用户登录实例讲解---(3)客户端验证
首先咱们看下注册页面的验证效果
以上验证主要包括
1.用户名不能为空
2.密码不能为空，密码长度不能小于5位数
3.确认密码不能为空，确认密码长度不能小于5位，确认密码必须和密码文本框输入的一致
4.邮箱格式必须正确。
以下是使用jquery.validate插件进行验证的代码

$("#form1").validate主要包括规则rules和提示信息messages两部分.
例如
rules:
{
UserName:
{
required:true
},
}
表示ID为UserName的文本框输入内容不能为空.
messages:
{
UserName:
{
required:"<span style='color:red'>用®?户¡ì名?不?能¨¹为a空?! </span>"
},
表示ID为UserName的文本框内容如果为空的话，给出提示信息.
onkeyup: 参数表示是否在按下键时执行验证
