具体的WxValidate.js文件的位置在wx-extend/src/assets/plugins/wx-validate/WxValidate.js
地址: https://github.com/skyvow/wx-extend/tree/master/src/assets/plugins/wx-validate
步骤一:将文件 WxValidate.js 拷贝到utils目录下
步骤二:2种引入方式 =》全局引入: 在app.js中写以下代码;局部引入:在需要的js文件下写以下代码【这里要写绝对路径】
import wxValidate from "./utils/wxValidate";
步骤三:wxml匹配规则,通过name
wxml 里 input 的name值必须和配置的rules的名称一致,否则匹配无效
步骤三:在js配置规则
import WxValidate from \'../../../utils/WxValidate\'; Page({ /*** 页面的初始数据*/ data: {}, onLoad: function(options) { /*** 4-1(先初始化表单)*/ this.initValidate(); }, /*** 表单-验证字段*/ initValidate() { /*** 4-2(配置规则)*/ const rules = { name: { required: true, rangelength: [2, 4] }, idcard: { required: true, idcard: true, }, tel: { required: true, tel: true, }, // 配置false可关闭验证 regcode: { required: false, minlength: 6 }, assistance: { required: true, assistance: true, }, } // 验证字段的提示信息,若不传则调用默认的信息 const messages = { name: { required: \'请输入姓名\', rangelength: \'请输入2~4个汉字个汉字\' }, tel: { required: \'请输入11位手机号码\', tel: \'请输入正确的手机号码\', }, idcard: { required: \'请输入身份证号码\', idcard: \'请输入正确的身份证号码\', }, regcode: { required: \'请输入验证码\', minlength: \'请输入正确的验证码\' }, assistance: { required: \'请勾选 《顺风男服务协议》\' }, }; // 创建实例对象 this.WxValidate = new WxValidate(rules, messages) /*** 也可以自定义验证规则*/ this.WxValidate.addMethod(\'assistance\', (value, param) => { return this.WxValidate.optional(value) || (value.length >= 1 && value.length <= 2) }, \'请勾选 《顺风男服务协议》\') }, submitForm(e) { /***4-3(表单提交校验)*/ const params = e.detail.value if (!this.WxValidate.checkForm(params)) { const error = this.WxValidate.errorList[0] this.showModal(error) return false } /*** 这里添写验证成功以后的逻辑**/ //验证通过以后-> this.submitInfo(params); }, /*** 表单-提交*/ submitInfo(params) { // form提交 let form = params; console.log(\'将要提交的表单信息:\', form); wx.showToast({ title: \'提交成功!!!!\', }) }, showModal(error) { wx.showModal({ content: error.msg, showCancel: false, }) } });

以上转自:https://www.cnblogs.com/cisum/p/9556736.html,逻辑如上
改:
步骤一:将文件 WxValidate.js 拷贝到utils目录
步骤二:在app.js中引入,并且实例化验证
//引入wxValidate.js文件
import wxValidate from "./utils/wxValidate";
//创建实例对象
wxValidate: (rules, messages) => new wxValidate(rules, messages),
/**原来是这么实例化的
this.WxValidate = new WxValidate(rules, messages)**/
步骤三:在wxml中写
<form report-submit bindsubmit="loginForm"> <input class="hide" name="reg_id" value="{{openid}}"/> <view class="form-item"> <i class="iconfont icon-shouji"></i> <input type="num" class="form-input" name="mobile" maxlength="11" value="{{remember.mobile}}" placeholder="请输入您的邮箱地址"/> </view> <view class="form-item"> <i class="iconfont icon-mima"></i> <input type="text" password="true" class="form-input" name="password" value="{{remember.password}}" placeholder="请输入您的密码"/> </view> <view class="form-btn"> <button formType="submit">登录</button> </view> </form>
步骤四:在js =》 onLoad方法中写
//配置验证规则和提示信息, that.WxValidate 是自己定义的这个验证规则的变量名,也可以是that.WxValidate2
var app = getApp()
Page({
onLoad: function (options) {
that.WxValidate = app.wxValidate( { mobile: { required: true, tel:true }, password: { required: true, } }, { mobile: { required: \'请输入手机号\', tel:\'请正确输入手机号\' }, password: { required: \'请输入密码\', } } )
}
})
步骤五:在js =》 loginForm方法中写 ,这个方法名对应form 的 bindsubmit 事件
//表单提交校验
loginForm: function (e) { var that = this;
//失败报错 if (!that.WxValidate.checkForm(e)) { const error = that.WxValidate.errorList[0]; wx.showToast({ title: error.msg, icon: \'none\', duration: 2000 }); return false }
//成功 后登录接口
}
表单提交校验结果:
that.WxValidate.errorList
form 表单的 的 bindsubmit 事件 传递的参数(e)结果如下
自定义添加验证规则,比如要验证手机号和身份证号同时
写在需要使用的页面onLoad
that.WxValidate = app.wxValidate({ login_id: { required: true, telOrCard: true, }, password: { required: true } }, { login_id: { required: \'请输入手机号/身份证号\', telOrCard: \'请正确输入手机号/身份证号\', }, password: { required: \'请输入密码\' } }) that.WxValidate.addMethod(\'telOrCard\',(value, param) =>{ return (/^1[34578]\d{9}$/.test(value) || /^[1-9]\d{5}[1-9]\d{3}((0\d)|(1[0-2]))(([0|1|2]\d)|3[0-1])\d{3}([0-9]|X)$/.test(value)) //匹配见WxValidate.js }, \'请正确输入手机号/身份证号\')
必须添加的要放下面,否则会报错
