使用对象

Question

我正在使用表单验证。我的代码工作正常，但每当我点击显示多个时间的发送按钮验证。在这里我想添加单选按钮，复选框，根据我的代码选择。我该如何添加其他字段？我尝试了我的水平，但无法实现。 任何人都可以帮我将其添加到其他领域吗？ 以下是我的代码：

＆＃13;

＆＃13;

    var Validator = function(formObject) {
        this.form = $(formObject);

        var Elements = {
            name: {
                reg: /^[a-zA-Z]{2,20}$/,
                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.",
            },

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

        var handleError = function(element, message) {
            element.addClass('input-error');
            var $err_msg = element.parent('div');
            var error = $('<div class="error"></div>').text(message);
            error.appendTo($err_msg);
            element.keyup(function() {
                $(error).fadeOut(1000, function() {
                    element.removeClass('input-error');
                });
            });

        };

        this.validate = function() {
        		var errorCount = 0;
            this.form.find("input, textarea").each(function(index, field){
                var type = $(field).data("validation");
                var validation = Elements[type];
                if (validation){
                    if (!validation.reg.test($(field).val())){
                    		errorCount++;
                        handleError($(field), validation.error);
                    }            
                }
            })
        		return errorCount == 0;
        };
    };

    $(function(){
        $("form#test").on("submit", function(event){
            //event.preventDefault();
            return new Validator(this).validate(); // "this" here refers to the form
            
        })
    })

Answer 1

  

每当我点击显示多个时间的发送按钮验证时

$err_msg.empty(); /* add this cleanup old errors */
error.appendTo($err_msg);

请检查此codepen：

我添加了这一行

$err_msg.find('.error').remove();

更新的代码：

var Validator = function(formObject) {
        this.form = $(formObject);

        var Elements = {
            name: {
                reg: /^[a-zA-Z]{2,20}$/,
                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.",
            },

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

        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);
            element.keyup(function() {
                $(error).fadeOut(1000, function() {
                    element.removeClass('input-error');
                });
            });

        };

        this.validate = function() {
                var errorCount = 0;
            this.form.find("input, textarea").each(function(index, field){
                var type = $(field).data("validation");
                var validation = Elements[type];
                if (validation){
                    if (!validation.reg.test($(field).val())){
                            errorCount++;
                        handleError($(field), validation.error);
                    }            
                }
            })
                return errorCount == 0;
        };
    };

    $(function(){
        $("form#test").on("submit", function(event){
            //event.preventDefault();
            return new Validator(this).validate(); // "this" here refers to the form

        })
    })
