[{ required: true, message: '为必填项', trigger: 'blur'}] 去除trigger [{ required: true, message: '为必填项'}] 都这
使用iview动态添加表单校验，触发 this.$refs[name].validate 方法校验的时候，会有一部分非 String 类型表单项提示校验未通过，console中显示 async-validator: [xxx is not a string]组件写法如下：console错误提示如下：去掉 :rules 规则中的 trigger 属性 再次触发 this.$refs[name].validate 方法校验...
var schema = require('async-validator'); var descriptor = { name: { type: "string", required: true, validator: (rule, value) => value === 'muji', }, }; var validator = new schema(descriptor); validator.validate({name: "muji"}, (errors, fields) => { if(errors) {{name : “...
validator.validate({name:"muji"},(errors, fields) =>{if(errors) {// validation failed, errors is an array of all errors// fields is an object keyed by field name with an array of// errors per field// 校验未通过的情况,errors 是所有错误的数组// fields 是一个 object,以字段作为 key ...
在使用ivew.design的时候,在源码中发现form表单的验证是使用Async Validator,然后就去看一下源码,了解原理并做一下整理。 const validator = new AsyncValidator(descriptor); let model = {}; model[this.prop] = this.fieldValue; validator.validate(model, { firstFields: true }, errors => { ...
{required:true,message:'数量必填',field:'limit',fullField:'limit',type:'string',validator:(rule,value,callback,source,options)=>{consterrors=[];consttype=Array.isArray(value)?'array':typeofvalue;rules.required(rule,value,source,errors,options,type);callback(errors);},},value:3,source:{...
前后端开发中,表单校验是一个常用且必要的功能。前端开发中一些 UI 库如Element、Ant Design表单组件都使用了async-validator作为校验库。 async-validator 功能与特性: 内置多种数据格式校验功能,包括数组、枚举、对象 异步校验库,支持自定义校验方法 一个字段支持多个校验规则,支持自定义字段错误信息 ...
{required:true,message:'数量必填',field:'limit',fullField:'limit',type:'string',validator:(rule,value,callback,source,options)=>{consterrors=[];consttype=Array.isArray(value)?'array':typeofvalue;rules.required(rule,value,source,errors,options,type);callback(errors);},},value:3,source:{...
register = function register(type, validator) { if (typeof validator !== 'function') { throw new Error('Cannot register a validator by type, validator is not a function'); } validators[type] = validator; }; 通过源码,我们也可以看到该校验器和内置校验器如array、boolean校验器平级。 因此...
const Validator = asyncValidator.default; // 定义校验规则 const rules = { name: { type: 'string', required: true, validator: (rule, value) => value === 'muji', }, age: { type: 'number', asyncValidator: (rule, value) => { ...
