Validieren Formular-input-Feldern mit jquery

Ich hoffe das ist, was Sie versuchen zu erreichen. Dies dauerte länger als erwartet, aber ich habe versucht, es zu erreichen. Diese ganze form ist benutzerdefinierte form. Sie hätte den vorhandenen plugins, um es zu erreichen. Alle, welche Wege es nahm viel Zeit, um es herauszufinden. Die Frage prüfen, wie die meisten Dinge funktionieren, zu ignorieren, wenn etwas ist nicht das, was Sie wollen.

JS:

$(document).ready(function() {

  /* contact form validation */
  var Validator = function(formObject) {
    this.form = $(formObject);
    var Elements = {
      name: {
        reg: /^[a-zA-Z ]{2,20}$/,
        require: true,
        error: "Not a valid name.",
      },

      email: {
        reg: /^[a-z-0-9_+.-]+\@([a-z0-9-]+\.)+[a-z0-9]{2,7}$/i,
        error: "Not a valid e-mail address.",
      },
      phone: {
        reg: /^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/,
        error: "Not a valid number.",
      },

      message: {
        reg: /^(?!\s*$).+/,
        error: "Message field cannot be empty.",
      },
      gender: {
        error: "gender is required",
      },
      selectOption: {
        error: "this field is required",
        required: true
      }
    };

    var handleError = function(element, message) {
      element.addClass('input-error');
      var $err_msg = element.parent('div');
      $err_msg.find('.error').remove();

      var error = $('<div class="error"></div>').text(message);
      error.appendTo($err_msg);
      console.log(element);


      element.on('keypress change', function() {
        $(error).fadeOut(1000, function() {
          console.log(element);
          element.removeClass('input-error');
        });
      });

    };

    /* Select Option */

    this.validate = function() {
      var errorCount = 0;

      this.form.find("select").each(function(index, field) {
        var type = $(field).data("validation");
        var validation = Elements[type];
        if ($(field).val() == "") {
          errorCount++;
          handleError($(field), validation.error);
        }
      });

      this.form.find("input, textarea").each(function(index, field) {
        var type = $(field).data("validation");
        var validation = Elements[type];
        if (validation !== undefined) {
          var re = new RegExp(validation.reg);
          if (validation) {
            if (!re.test($(field).val())) {
              errorCount++;
              handleError($(field), validation.error);
            }
          }
        }
      })

      /* Radio button */

      var radioList = $('input:radio');
      var radioNameList = new Array();
      var radioUniqueNameList = new Array();
      var notCompleted = 0;
      for (var i = 0; i < radioList.length; i++) {
        radioNameList.push(radioList[i].name);
      }
      radioUniqueNameList = jQuery.unique(radioNameList);
      console.log(radioUniqueNameList);
      for (var i = 0; i < radioUniqueNameList.length; i++) {
        var field = $('#' + radioUniqueNameList[i]);
        var type = field.data("validation");
        var validation = Elements[type];
        if ($('input[name=' + type + ']:checked', '#test').val() == undefined) {
          errorCount++;
          handleError($(field), validation.error);
        }
      }

      return errorCount == 0;
    };
  };

  /* Submit form*/

  $(function() {

    $("form#test").on('submit', function(e) {
      var NoErrors = new Validator(this).validate();
      if (NoErrors == true) {
        $.ajax({
          url: this.action,
          type: this.method,
          data: $(this).serialize(),
          success: function() {
            //AJAX request finished, handle the results and error msg
            $('.success_msg').fadeIn().delay(3000).fadeOut();
            $('input[type!="submit"], textarea').val('').removeClass('error');
          }
        });

      }
      return false;
    })

  })

});
