self.$validate(true,function () {

if(!self.$validatorMethod.invalid){
alert("登录成功");
}
})
}
},
computed:{
matchPassword:function () {
return this.password == this.newpassword
}
}
})
</script>
</html>
2.同时验证多个情况，也可以把验证码方法写在html 中（个人不建议使用）
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<!--<script src="src/vue.min.js"></script>

<style>
.red {
color: red;
}
.btn{
display: inline-block;
padding: 10px;
background: orange;
color: #FFF;
cursor: pointer;
}
.btn:hover{
background: orangered;
}
</style>
</head>
<body id="app">
<validator name="validatorMethod">
<div class="username">
<label for="">用户名：</label>
<!-- 或者这么写-->
<!-- <input type="text" v-model="username" initial="off" v-validate:username="{noempty:true,username:true}" placeholder="请输入用户名">-->
<input type="text" v-model="username" initial="off" v-validate:username="['noempty','username']" placeholder="请输入用户名">

<p class="red" v-if="$validatorMethod.password.minlength">密码最低6位数</p>
<p class="red" v-if="$validatorMethod.password.maxlength">密码最高20位数</p>
<p class="red" v-if="$validatorMethod.password.pattern">只能是数字</p>
</div>
<div><a @click="loginMethods" class="btn">登录</a></div>
</validator>
</body>
<script>
var vue = new Vue({
el: '#app',
data: {
comment:"",
username: "",
password: "",
newpassword:""
},
validators: {
noempty:function(val){
var reg = /^s*$/g, isFlag = true;
if(val == "" || reg.test(val)){
isFlag = false;
}
return isFlag;
},
username: function (val) {
return /^[A-Za-z0-9_-u4e00-u9fa5]{1,10}$/.test(val);
},
integer: function (val) {
return /^[1-9]d*$/.test(val);
}
},
methods:{
loginMethods:function () {
var self = this;
/**
* 验证目标表单元素。
* true:验证所有
*/
self.$validate(true,function () {
/*如果所有条件都是false*/
if(!self.$validatorMethod.invalid){
alert("登录成功");
}
})
}
}
})
</script>
</html>
3.提交时验证所有表单：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<!--<script src="src/vue.min.js"></script>
<script src="src/vue-validator.min.js"></script>-->
<script src="https://unpkg.com/vue@1.0.26/dist/vue.min.js"></script>
<script src="https://unpkg.com/vue-validator@2.1.7/dist/vue-validator.min.js"></script>
<style>
.red {
color: red;
}
.btn{
display: inline-block;
padding: 10px;
background: orange;
color: #FFF;
cursor: pointer;
}
.btn:hover{
background: orangered;
}
</style>
</head>
<body id="app">
<validator name="validatorMethod">
<div class="username">
<label for="">用户名：</label>
<input type="text" v-model="username" initial="off" v-validate:username="['username']" placeholder="请输入用户名">
<p class="red" v-if="$validatorMethod.username.username">由数字、26个英文字母或下划线和中文组成的字符串</p>
</div>
<div class="password">
<label for="">密码：</label>
<input type="password" v-model="password" initial="off" v-validate:password="['integer']" placeholder="请输入密码">
<p class="red" v-if="$validatorMethod.password.integer">只能是数字</p>
</div>
<div><a @click="loginMethods" class="btn">登录</a></div>
</validator>
</body>
<script>
var vue = new Vue({
el: '#app',
data: {
username: "",
password: ""
},
validators: {
username: function (val) {
return /^[A-Za-z0-9_-u4e00-u9fa5]{1,10}$/.test(val);
},
integer: function (val) {
return /^[1-9]d*$/.test(val);
}
},
methods:{
loginMethods:function () {
var self = this;
/**
* 验证目标表单元素。
* true:验证所有
*/
self.$validate(true,function () {
/*如果所有条件都是false*/
if(!self.$validatorMethod.invalid){
alert("登录成功");
}
})
}
}
})
</script>
</html>
4.提交时指定表单验证：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<!--<script src="src/vue.min.js"></script>
<script src="src/vue-validator.min.js"></script>-->
<script src="https://unpkg.com/vue@1.0.26/dist/vue.min.js"></script>
<script src="https://unpkg.com/vue-validator@2.1.7/dist/vue-validator.min.js"></script>
<style>
.red {
color: red;
}
.btn{
display: inline-block;
padding: 10px;
background: orange;
color: #FFF;
cursor: pointer;
}
.btn:hover{
background: orangered;
}
</style>
</head>
<body id="app">
<validator name="validatorMethod">
<div class="username">
<label for="">用户名：</label>
<input type="text" v-model="username" initial="off" v-validate:username="['username']" placeholder="请输入用户名">
<p class="red" v-if="$validatorMethod.username.username">由数字、26个英文字母或下划线和中文组成的字符串</p>
</div>
<div class="password">
<label for="">密码：</label>
<input type="password" v-model="password" placeholder="请输入密码">
<p class="red" v-if="$validatorMethod.password.integer">只能是数字</p>
</div>
<div><a @click="loginMethods" class="btn">登录</a></div>
</validator>
</body>
<script>
var vue = new Vue({
el: '#app',
data: {
username: "",
password: ""
},
validators: {
username: function (val) {
return /^[A-Za-z0-9_-u4e00-u9fa5]{1,10}$/.test(val);
},
integer: function (val) {
return /^[1-9]d*$/.test(val);
}
},
methods:{
loginMethods:function () {
var self = this;
/**
* 验证[username]表单元素。
*/
self.$validate('username',function () {
/*如果所有条件都是false*/
if(!self.$validatorMethod.username.username){
alert("登录成功");
}
})
}
}
})
</script>
</html>
5.v-model 是对象类型的参数提交时验证所有表单 ：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<!--<script src="src/vue.min.js"></script>-->
<!--<script src="src/vue-validator.min.js"></script>-->
<script src="https://unpkg.com/vue@1.0.26/dist/vue.min.js"></script>
<script src="https://unpkg.com/vue-validator@2.1.7/dist/vue-validator.min.js"></script>
<style>
.red {
color: red;
}
.btn{
display: inline-block;
padding: 10px;
background: orange;
color: #FFF;
cursor: pointer;
}
.btn:hover{
background: orangered;
}
</style>
</head>
<body id="app">
<validator name="validatorMethod">
<div class="username">
<label for="">用户名：</label>
<input type="text" v-model="items.username" initial="off" v-validate:username="['username']" placeholder="请输入用户名">
<p class="red" v-if="$validatorMethod.username.username">由数字、26个英文字母或下划线和中文组成的字符串</p>
</div>
<div class="password">
<label for="">密码：</label>
<input type="password" v-model="items.password" initial="off" v-validate:password="['integer']" placeholder="请输入密码">
<p class="red" v-if="$validatorMethod.password.integer">只能是数字</p>
</div>
<div><a @click="loginMethods" class="btn">登录</a></div>
</validator>
</body>
<script>
var vue = new Vue({
el: '#app',
data: {
items:{
username: "",
password: ""
}
},
validators: {
username: function (val) {
return /^[A-Za-z0-9_-u4e00-u9fa5]{1,10}$/.test(val);
},
integer: function (val) {
return /^[1-9]d*$/.test(val);
}
},
methods:{
loginMethods:function () {
var self = this;
/**
* 验证目标表单元素。
* true:验证所有
*/
self.$validate(true,function () {
/*如果所有条件都是false*/
if(!self.$validatorMethod.invalid){
alert("登录成功");
}
})
}
}
})
</script>
</html>
6.v-model 参数命名是驼峰式提交时验证所有表单：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<!--<script src="src/vue.min.js"></script>-->
<!--<script src="src/vue-validator.min.js"></script>-->
<script src="https://unpkg.com/vue@1.0.26/dist/vue.min.js"></script>
<script src="https://unpkg.com/vue-validator@2.1.7/dist/vue-validator.min.js"></script>
<style>
.red {
color: red;
}
.btn{
display: inline-block;
padding: 10px;
background: orange;
color: #FFF;
cursor: pointer;
}
.btn:hover{
background: orangered;
}
</style>
</head>
<body id="app">
<validator name="validatorMethod">
<div class="username">
<label for="">用户名：</label>
<input type="text" v-model="items.userName" initial="off" v-validate:user-name="['username']" placeholder="请输入用户名">
<p class="red" v-if="$validatorMethod.userName.username">由数字、26个英文字母或下划线和中文组成的字符串</p>
</div>
<div class="password">
<label for="">密码：</label>
<input type="password" v-model="items.passWord" initial="off" v-validate:pass-word="['integer']" placeholder="请输入密码">
<p class="red" v-if="$validatorMethod.passWord.integer">只能是数字</p>
</div>
<div><a @click="loginMethods" class="btn">登录</a></div>
</validator>
</body>
<script>
var vue = new Vue({
el: '#app',
data: {
items:{
userName: "",
passWord: ""
}
},
validators: {
username: function (val) {
return /^[A-Za-z0-9_-u4e00-u9fa5]{1,10}$/.test(val);
},
integer: function (val) {
return /^[1-9]d*$/.test(val);
}
},
methods:{
loginMethods:function () {
var self = this;
/**
* 验证目标表单元素。
* true:验证所有
*/
self.$validate(true,function () {
/*如果所有条件都是false*/
if(!self.$validatorMethod.invalid){
alert("登录成功");
}
})
}
}
})
</script>
</html>
