微信小程序 - 表单验证插件WxValidate使用

Github地址：WxValidate

1. 拷贝至util目录

2.项目引入

3.查看wxml匹配规则，通过name

 4.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();
},

showModal(error) {
wx.showModal({
content: error.msg,
showCancel: false,
})
},

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！！！！',
})
},

/**
* 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》')
}
});
