The following describes how to use the jquery. validate plug-in.Verification Code
[Html] <% @ Page Language = "C #" Inherits = "System. Web. Mvc. ViewPage <MvcLogin. Models. RegisterModel>" %> <! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN "" http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd "> <Html xmlns =" http://www.w3.org/1999/xhtml "> <Head runat =" server "> <title> registration page </title> <script type =" text/javascript "src = ".. /.. /Scripts/jquery-1.4.1-vsdoc.js "> </script> <script type =" text/javascript "src = ".. /.. /Scripts/jquery. validate. js "> </script> <script type =" text/javascript "> $ (). ready (function () {$ ("# form1 "). validate ({rules: {UserName: {required: true}, UserPwd: {required: true, minlength: 6}, ConfirPwd: {required: true, m Inlength: 6, failed to: "# UserPwd"}, Email: {email: true }}, messages: {UserName: {required: "<span style = 'color: red'> the user name cannot be blank! </Span> "}, UserPwd: {required:" <span style = 'color: red'> the password cannot be blank! </Span> ", minlength: jQuery. format (" <span style = 'color: red'> the password length cannot be less than {0} characters! </Span> ")}, ConfirPwd: {required:" <span style = 'color: red'> confirm that the password cannot be blank! <Span> ", minlength: jQuery. format (" confirm that the password length cannot be less than {0} characters! "), Failed to:" <span style = 'color: red'> the two passwords are inconsistent! </Span> "}, Email: {email:" <span style = 'color: red'> Incorrect Email format! </Span> "}}, onkeyup: false });}); </script>
$ ("# Form1"). validate mainly includes rule rules and message.
For example
rules: { UserName: { required:true },}
The input content in the text box with ID UserName cannot be blank.
Messages: {UserName: {required: "<span style = 'color: red'> Use®? User name? No? Can you leave a blank ?! </Span> "},
If the text box with ID UserName is empty, a prompt is displayed.
The above is the whole process of client verification using the jquery. validate plug-in. I hope it will be helpful for everyone.
