Jquery-validation中的Meteor Method.call问题

Question

我有一个表单来更改密码。我需要验证旧密码。但是jquery addMethod总是在false中返回Meteor.call。如何使其可行。或者有什么办法吗？我的波纹管代码将是关于我的问题的更多细节。

  $.validator.addMethod( 'checkPassword', ( oldpassword ) => {
    var digest = Package.sha.SHA256(oldpassword);
    Meteor.call('checkPassword', digest, function(err, result) {
     var res = result.error != null; // even if this is "true", error message is visible.
     return res;
    });
  });


  $( "#changepassword" ).validate({
        rules: {
          oldpassword: {
            required: true,
            checkPassword: true
          }
        },
        messages: {
          oldpassword: {
            required: "Please enter your Old Password",
            checkPassword: "Password doesnt match!!!" //this message is visible all the time.
          }    }
      });

这是我的方法调用

Meteor.methods({
  checkPassword: function(digest){
    if (Meteor.isServer) {
       if (this.userId) {
        var user = Meteor.user();
        var password = {digest: digest, algorithm: 'sha-256'};
        var result = Accounts._checkPassword(user, password);
        return result;
    }
  }
}
});
