如何在客户端流星中使用自动格式化中的正则表达式来验证字段的输入值？

Question

i'm new to meteor framework and i'm building a form which needs validation of fields using regular expression in client side.

schema.js

   PRODUCT_BUILD:{
    type:String,
    label:' PRODUCT_BUILD', 
    defaultValue:"PRODUCT:latest",
    regEx: /^(PRODUCT)((\/(([0-9]+\.)+[0-9]+))|(\:(latest)))/
  },

I have written the message as

SimpleSchema.messages({
 'regEx PRODUCT_BUILD': "Can have eg: PRODUCT/10.X.X.1234 or PRODUCT:latest",
});

test.html

 {{> afQuickField name='PRODUCT_BUILD'}}

I have entered all the fields which regex needs, but when I give the invalid input it dosen't check the regex and also the error message.
Can anyone tell me what i can do to correct it?

As for as I remember, the way simple schema messages are handled have been changed in the recent versions of simple-schema / autoform.

Ideally, it used to be something like this (which I'm not sure if it's going to work on your version):

SimpleSchema.messages({
  "regEx PRODUCT_BUILD": [
    { msg: "Can have eg: PRODUCT/10.X.X.1234 or PRODUCT:latest" }
  ]
});

There is an alternate method using custom field validation as below:

  PRODUCT_BUILD:{
    type:String,
    label:' PRODUCT_BUILD', 
    defaultValue:"PRODUCT:latest",
    custom: function(){
            if(this.value){
               // do the regex validation using normal JS
              //if validation fails,
               return "regexError"
             }
           }
  },


SimpleSchema.messages({
  "regexError":  "Can have eg: PRODUCT/10.X.X.1234 or PRODUCT:latest" 

});
