是的,要写好校验规则。1、将校验规则写到控件中<script src="../js/jquery.js" type="text/javascript"></script><script src="../js/jquery.validate.js" type="text/javascript"></script><script src="./js/jquery.metadata.js" type="text/javascript"></script>$().ready(function() {$("#signupForm").validate();});<form id="signupForm" method="get" action=""><p><label for="firstname">Firstname</label><input id="firstname" name="firstname" class="required" /></p><p><label for="email">E-Mail</label><input id="email" name="email" class="required email" /></p><p><label for="password">Password</label><input id="password" name="password" type="password" class="{required:true,minlength:5}" /></p><p><label for="confirm_password">确认密码</label><input id="confirm_password" name="confirm_password" type="password" class="{required:true,minlength:5,equalTo:'#password'}" /></p><p><input class="submit" type="submit" value="Submit"/></p></form>2.将校验规则写到js代码中$().ready(function() {$("#signupForm").validate({rules: {firstname: "required",email: {required: true,email: true},password: {required: true,minlength: 5},confirm_password: {required: true,minlength: 5,equalTo: "#password"}},messages: {firstname: "请输入姓名",email: {required: "请输入Email地址",email: "请输入正确的email地址"},password: {required: "请输入密码",minlength: jQuery.format("密码不能小于{0}个字 符")},confirm_password: {required: "请输入确认密码",minlength: "确认密码不能小于5个字符",equalTo: "两次输入密码不一致不一致"}}});});
