[JavaScript知识库]el-form的验证表单（全表-部分-单个）字段

1、全表校验

this.$refs.czxxInfo.validate((valid) => {
    if (valid) {
        
        }
    })

2、部分校验

let fieldsToValidate = ['name', 'name1','name2','name3'];
  Promise.all(fieldsToValidate.map(item => {
      return new Promise(function (resolve, reject) {
          _this.$refs.czxxInfo.validateField(item, error => {
              resolve(error);
              console.log(reject)
            })
        });
  })).then((data) => {
      //返回结果为data:['','','','',]全部为空，满足规则
      data.find(value=>{
        if(value!=""){
            
        }else{
            
        }
      })
    })

3、单个字段校验

 this.$refs.xjjzxx.validateField('countyJz.rdlx',(Error) =>{
    if(!Error){
          
    }else {
     
    }
  })
