jquery.validate ajax方式验证
<script type="text/javascript"> $(function () { $("#form1").validate({ rules: { pwd: { required: true, remote: { url: "@Url.Action("ValidatePwd", "UserInfo")", type: "post", dataType: "json", data: { pwd: function () { return $("#pwd").val(); //这个是取要验证的密码 } }, dataFilter: function (data) { //判断控制器返回的内容 if (data == "true") { return true; } else { return false; } } } }, password: { required: true, rangelength: [6, 16] }, confirm_password: { required: true, rangelength: [6, 16], equalTo: "#password" } }, messages: { pwd: { required: "请填写原始密码!", remote: "原始密码不正确,请重新填写!" //这个地方如果不写的话,是自带的提示内容,加上就是这个内容。 }, password: { required: "请填写新密码", minlength: jQuery.format("登录名长度在6-12位之间!") }, confirm_password: { required: "请填写确认密码!", minlength: "密码需由6-16个字符(数字、字母、下划线)组成!", equalTo: "两次输入密码不一致!" } }, onfocus: true, onkeyup: false, //这个地方要注意,修改去控制器验证的事件。 onsubmit: false });
2.案例
<script> $().ready(function() { $("#cForm").validate({ onsubmit:true,// 是否在提交是验证 onfocusout:false,// 是否在获取焦点时验证 onkeyup :false,// 是否在敲击键盘时验证 rules: { //规则 user: { //要对应相对应的input中的name属性 required: true }, password: { required: true } }, messages:{ //验证错误信息 user: { required: "请输入用户名" }, password: { required: "请输入密码" } }, submitHandler: function(form) { //通过之后回调 //进行ajax传值 $.ajax({ url : "{:U(‘user/index‘)}", type : "post", dataType : "json", data: { user: $("#user").val(), password: $("#password").val() }, success : function(msg) { //要执行的代码 } }); }, invalidHandler: function(form, validator) {return false;} }); }); </script>
2.1 使用
<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/lib/jquery.js"></script> <script src="http://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js"></script>
菜鸟教程:http://www.runoob.com/jquery/jquery-plugin-validate.html
$().ready(function() { // 在键盘按下并释放及提交后验证提交表单 $("#signupForm").validate({ rules: { firstname: "required", lastname: "required", username: { required: true, minlength: 2 }, password: { required: true, minlength: 5 }, confirm_password: { required: true, minlength: 5, equalTo: "#password" }, email: { required: true, email: true }, topic: { required: "#newsletter:checked", minlength: 2 }, agree: "required" }, messages: { firstname: "请输入您的名字", lastname: "请输入您的姓氏", username: { required: "请输入用户名", minlength: "用户名必需由两个字母组成" }, password: { required: "请输入密码", minlength: "密码长度不能小于 5 个字母" }, confirm_password: { required: "请输入密码", minlength: "密码长度不能小于 5 个字母", equalTo: "两次密码输入不一致" }, email: "请输入一个正确的邮箱", agree: "请接受我们的声明", topic: "请选择两个主题" } });
校验规则中的名字必须与input中的name值对应
3. 常用方法及注意问题
3.1我们可以用其他方式替代默认的 submit
$().ready(function() { $("#signupForm").validate({ submitHandler:function(form){ //表单提交后要执行的内容 form.submit(); } }); });
使用ajax
$(".selector").validate({ submitHandler: function(form) { $(form).ajaxSubmit(); } })
3.2debug,只验证不提交表单
$().ready(function() { $("#signupForm").validate({ debug:true }); });
如果一个页面中有多个表单都想设置成为 debug,则使用:
$.validator.setDefaults({ debug: true })
3.3ignore:忽略某些元素不验证
ignore: ".ignore"
3.4更改错误信息显示的位置
errorPlacement:Callback
指明错误放置的位置,默认情况是:error.appendTo(element.parent());即把错误信息放在验证的元素后面。
errorPlacement: function(error, element) { error.appendTo(element.parent()); }
3.5更改错误信息显示的样式
设置错误提示的样式,可以增加图标显示,在该系统中已经建立了一个 validation.css,专门用于维护校验文件的样式
input.error { border: 1px solid red; } label.error { background:url("./demo/images/unchecked.gif") no-repeat 0px 0px; padding-left: 16px; padding-bottom: 2px; font-weight: bold; color: #EA5200; } label.checked { background:url("./demo/images/checked.gif") no-repeat 0px 0px; }
3.6每个字段验证通过执行函数
success: function(label) { // set as text for IE label.html(" ").addClass("checked"); //label.addClass("valid").text("Ok!") }
3.7验证的触发方式修改
重置表单 很实用
$().ready(function() { var validator = $("#signupForm").validate({ submitHandler:function(form){ alert("submitted"); form.submit(); } }); $("#reset").click(function() { validator.resetForm(); }); });
3.8异步验证
remote: { url: "check-email.php", //后台处理程序 type: "post", //数据发送方式 dataType: "json", //接受数据格式 data: { //要传递的数据 username: function() { return $("#username").val(); } } }
3.9添加自定义校验
addMethod:name, method, message
// 中文字两个字节 jQuery.validator.addMethod("byteRangeLength", function(value, element, param) { var length = value.length; for(var i = 0; i < value.length; i++){ if(value.charCodeAt(i) > 127){ length++; } } return this.optional(element) || ( length >= param[0] && length <= param[1] ); }, $.validator.format("请确保输入的值在{0}-{1}个字节之间(一个中文字算2个字节)")); // 邮政编码验证 jQuery.validator.addMethod("isZipCode", function(value, element) { var tel = /^[0-9]{6}$/; return this.optional(element) || (tel.test(value)); }, "请正确填写您的邮政编码");
3.10radio 和 checkbox、select 的验证
