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
