小程序基础开发（四）：weui-wxss组件表单页面，WxValidate.js组件表单验证上传

一，使用weui-wxss组件做一个表单页面

WeUI组件库简介
这是一套基于样式库weui-wxss开发的小程序扩展组件库，同微信原生视觉体验一致的UI组件库，由微信官方设计团队和小程序团队为微信小程序量身设计，令用户的使用感知更加统一。

项目背景
随着小程序的普及，微信也有很多内部小程序在开发，每个小程序都需要从零到1进行开发设计，而这个过程中，有大量的UI交互是重复的，另外，微信内部已经有一套H5版本的WeUI样式库。综合考虑，我们基于WeUI样式库开发了小程序版本的UI组件库，在内部多个小程序项目已经使用OK的情况下，我们把这套组件库开源让外部开发者也可以使用，欢迎大家Star以及提Issue。

@import '../../../weui.wxss';

textarea{
height: 120rpx;
border: 1px #ccc solid;
}
.change_img{
background-color: rgb(124, 124, 124);
padding: 0px 10px;
color: #fff;
border-radius: 2px;
}
.user_img{
height: 200rpx;
width: 200rpx;
margin: 5px auto;
}

.submit {

color: #fff;
}
.usgu_guide_cardImg{
max-width: 300rpx;
max-height: 600rpx;
margin: 3px auto;
}

二，引用WxValidate.js组件验证表单以及自定义验证条件

下载地址WxValidate.js

创建规则和提示

// 验证规则
const rules = {
comp_surname: {
required: true,
maxlength: [5],
Chinese: true
},
comp_name: {
required: true,
maxlength: [6],
Chinese: true
},
comp_work_address:{
required: true,
maxlength: [30],
},
comp_email: {
required: true,
email: true,
},
comp_mobile: {
required: true,
tel: true,
},
usgu_guide_card:{
required: true,
maxlength: [22],
EnglishNum: true,
}
// 配置false可关闭验证
};
// 验证提示信息
const messages = {
comp_surname: {
Chinese: '姓氏只能为汉字',
maxlength: '姓氏不可超过5个字',
required:'姓氏不可为空'
},
comp_name: {
Chinese: '名字只能为汉字',
maxlength: '名字不可超过5个字',
required:'名字不可为空'
},
comp_work_address:{
maxlength: '详细地址不可超过30个字',
required:'地址不可为空'
},
usgu_guide_card:{
maxlength: '资格证号不可超过22个字符',
EnglishNum:'资格证号只能输入英文或者数字'
required:'证件不可为空'
}
};

// 创建实例对象
this.WxValidate = new WxValidate(rules, messages)

过滤，验证
不符合条件的都会弹出窗消息提示错误

formSubmit: function (e) {
var that = this;
console.log(e.detail.value);
if (!this.WxValidate.checkForm(e.detail.value)) {
const error = this.WxValidate.errorList[0]
wx.showModal({
content: error.msg,
showCancel: false,
})
return false
}
else
{
//上传
}
}

如果希望空值时是wx.showToast消息框提示，则可以关闭required验证，在过滤条件时判断字段值的长度

formSubmit: function (e) {
var that = this;
console.log(e.detail.value);
if (!this.WxValidate.checkForm(e.detail.value)) {
const error = this.WxValidate.errorList[0]
wx.showModal({
content: error.msg,
showCancel: false,
})
return false
}
else if (e.detail.value.comp_surname.length == 0) {
wx.showToast({
title: '请填写姓氏!',
icon: 'loading',
duration: 1500
})
setTimeout(function () {
wx.hideToast()
}, 2000)
}
else if (e.detail.value.comp_name.length == 0) {
wx.showToast({
title: '请填写名字!',
icon: 'loading',
duration: 1500
})
setTimeout(function () {
wx.hideToast()
}, 2000)
}
else if (e.detail.value.comp_sex.length == 0) {
wx.showToast({
title: '请选择性别!',
icon: 'loading',
duration: 1500
})
setTimeout(function () {
wx.hideToast()
}, 2000)
}
else if (e.detail.value.comp_mobile.length == 0) {
wx.showToast({
title: '请填写电话!',
icon: 'loading',
duration: 1500
})
setTimeout(function () {
wx.hideToast()
}, 2000)
}
else if (e.detail.value.comp_work_pcp.length == 0) {
wx.showToast({
title: '请选择地址!',
icon: 'loading',
duration: 1500
})
setTimeout(function () {
wx.hideToast()
}, 2000)
}
else if (e.detail.value.comp_birth_pcp.length == 0) {
wx.showToast({
title: '请选择籍贯!',
icon: 'loading',
duration: 1500
})
setTimeout(function () {
wx.hideToast()
}, 2000)
}
else if (e.detail.value.usgu_class.length == 0) {
wx.showToast({
title: '请选择职业!',
icon: 'loading',
duration: 1500
})
setTimeout(function () {
wx.hideToast()
}, 2000)
}
else if (e.detail.value.usgu_guide_card.length == 0) {
wx.showToast({
title: '请填写资格证号!',
icon: 'loading',
duration: 1500
})
setTimeout(function () {
wx.hideToast()
}, 2000)
}
else if (e.detail.value.read.length == 0) {
wx.showToast({
title: '请同意相关条款',
icon: 'loading',
duration: 1500
})
setTimeout(function () {
wx.hideToast()
}, 2000)
}
else {
//提交
}
}

添加自定义条件
在/*** 初始化默认验证方法*/that.methods里添加正则

/**只能输入汉字 */
Chinese(value) {
return that.optional(value) || /^[\u4e00-\u9fa5]+$/.test(value)
},
/**只能输入英文和数字 */
EnglishNum(value){
return that.optional(value) || /^[0-9a-zA-Z]+$/.test(value)
}

在/*** 初始化默认提示信息*/this.defaults里添加提示

Chinese: this.formatTpl('请输入{0}位以内的汉字。'),
EnglishNum: this.formatTpl('请输入{0}位以内的英文或者数字。'),
