Validator

The Validator class allows to verify the validity of a value for a data type. NOTE: The Validator class is an independent code which can be used without Objective.js in any project in JavaScript .

  1. function Validator() {
  2. }
  3.  
  4. Validator.prototype = Object.create(Objective.prototype);
  5.  
  6. Object.defineProperty(Validator.prototype, 'constructor', { value: Validator, enumerable: false, writable: true });
  7.  
  8. Validator.validateColor = function(color) {
  9.     return typeof color === 'string' && /^#(?:[0-9a-fA-F]{3}){1,2}$/.test(color);
  10. };
  11.  
  12. Validator.normalizeColor = function(color) {
  13.     return color.length == 4 ? color.replace(/([0-9a-fA-F])/g, '$1$1').toLowerCase() : color.toLowerCase();
  14. };
  15.  
  16. Validator.easingOptions = ['linear', 'ease', 'ease-in', 'ease-out', 'ease-in-out' ];
  17.  
  18. Validator.validateEasing = function(easing) {
  19.     return typeof easing === 'string' && Validator.easingOptions.indexOf(easing) != -1;
  20. };
  21.  
  22. Validator.textAlignmentOptions = ['left', 'center', 'right' ];
  23.  
  24. Validator.validateTextAlignment = function(alignment) {
  25.     return typeof alignment === 'string' && Validator.textAlignmentOptions.indexOf(alignment) != -1;
  26. };
  27.  
  28. Validator.validateFileName = function(filename) {
  29.     return typeof filename === 'string' &&  /^[a-zA-Z]+[0-9a-zA-Z._-]*(.[0-9a-zA-Z]+)?$/.test(filename);
  30. };
  31.  
  32. Validator.validateCookieName = function(cookiename) {
  33.     return typeof cookiename === 'string' &&  /^[a-zA-Z]+[0-9a-zA-Z._-]*$/.test(cookiename);
  34. };
  35.  
  36. Validator.validateModelName = function(modelname) {
  37.     return Validator.validateCookieName(modelname);
  38. };
  39.  
  40. Validator.validateImageDataURL = function(dataurl) {
  41.     return typeof dataurl === 'string' && /^data:image\/[-.+0-9a-zA-Z]+;base64,/.test(dataurl);
  42. };
