Could you example custom "jquery validate" with "Meteor Method"? Example: unique name,...

[themeteorchef]

I'm not sure I understand, can you give me more details? jQuery Validate is meant only for client-side validation.

Here's an example from Base on how to define that: https://github.com/themeteorchef/base/blob/master/imports/modules/login.js#L31

Example I would like to create staff form

// Fields
name // unique
gender
dateOfBirth
address

And then set name field with unique, so I need to create custom validate on jquery validate that check the value on Meteor.methods({......}).

[thearabbit]

Like the simple schema

username: {
  type: String,
  custom: function () {
    if (Meteor.isClient && this.isSet) {
      Meteor.call("accountsIsUsernameAvailable", this.value, function (error, result) {
        if (!result) {
          Meteor.users.simpleSchema().namedContext("createUserForm").addInvalidKeys([{name: "username", type: "notUnique"}]);
        }
      });
    }
  }
}

@thearabbit take a peek at this https://themeteorchef.com/tutorials/validating-forms-with-jquery-validation

Look great tutorials. but I would like to use custom validate with Meteor Method on Server.

$.validator.addMethod( 'bookUnique', ( title ) => {
   Meteor.call('bookUnique', title,(error, result){
      return result; // Can't return, and waiting
   });
});

// Method
Meteor.methods({
   bookUnique(title){
      let exists = Books.findOne( { "title": title }, { fields: { "title": 1 } } );
      return exists ? false : true;
   }
});

Please help me, bc I can not return Meteor.call().

[themeteorchef]

You'll need to use a session variable or Reactive Var to get the response out of the Meteor.call block. Something like this...

Session.setDefault('isBookUniqueValidation', true);

$.validator.addMethod( 'bookUnique', ( title ) => {
   Meteor.call('bookUnique', title,(error, result){
      Session.set('isBookUniqueValidation', result);
   });
   return Session.get('isBookUniqueValidation');
});

I tried this too, but if my method do for a long time so it don't wait the method. (it mean that the submit is success without check custom validate method)

[themeteorchef]

In that case you'll want it to be false by default instead of true so that the validation blocks indefinitely. Not much you can do there if your method is slow to respond.

Thanks I understand.
