jQuery Validate addMethod() argument always return true

Question

I have a custom validation rule, so I am using to check it using addMethod. On rules, I am sending some JSON formatted string to be fetched on the addMethod .

$.validator.addMethod("chkduplicate", function(value, element, params) {
    console.log(params);
}, "This field value already exists.");

Rules should look like:

rules: {
  meter_id: {
    required: true,
    digits: true,
    chkduplicate: '{ "table_name": "users", "fld_name": "user_id"}'
  }
}

here chkduplicate is the parameter I am sending to addMethod, but when I try to console the params, it always returns true, but it should be {"table_name": "users", "fld_name": "user_id"}'

I am using this plugin

Answer 1

params Type: Object parameters specified for the method, eg for min: 5, the parameter is 5, for range: [1, 5] it's [1, 5]

Yours is string; try this

rules: {
  meter_id: {
    required: true,
    digits: true,
    chkduplicate: { "table_name": "users", "fld_name": "user_id"}
  }
}
