tuna-angular-unobtrusive-validation v1.0.3

README

MVC C# data annotations for angularjs. Replaces the need for jquery validation framework(s).

Goals:

• Simple
• Lightwight
• Easily extendable

How to install

npm install tuna-angular-unobtrusive-validation --save

Usage

It is possible to configure the attribute name to match against (default for jquery-unobtrusive-validation is "val", that is what MVC will generate):

Tuna.ValidatorAttrName = "val";

The plugin has a global variable named Tuna.Validators, it contains two properties that can be configured.

• Tuna.Validators.texts: containing texts for validators.
• Tuna.Validators.rules: functions that validates input.

Existing validations:

• regex: 'Invalid value',
• date: 'Invalid date',
• email: 'Invalid email',
• range: 'Range must be between {0} and {1}',
• digits: 'Only digits allowed',
• number: 'Only numbers allowed',
• required: 'Required field',
• equalto: '{0} must match {1}'

Change default messages, globally

Tuna.Validators.texts["required"] = "override default custom text";

Change default messages, inline

<input type="input" data-val="true" data-val-required="will override default text" />

Change existing validation

Tuna.Validators.rules["required"] = function (scope, element, attrs) { 
  return function (modelValue, viewValue) { 
    return viewValue != ""; //true === is valid.
  }
};

Add custom validation

Tuna.Validators.texts["nozero"] = "zeros are not allowed!";
Tuna.Validators.rules["nozero"] = function (scope, element, attrs) {
  var regex = new RegExp(/^[0]$/);
  return function (modelValue, viewValue) {
    return !regex.test(viewValue || '');
  };
};

//add error callback
Tuna.ValidatorEvents.onElementError = function (ngModel, element, text) {
  alert(text);
 }

<input type="input" placeholder="no zeros" data-val="true" data-val-nozero />
<input type="input" placeholder="no zeros" data-val="true" data-val-nozero="override nozero text" />
