你能帮我清理这段代码吗

理想情况下，我想生成一个validateEmail()带参数(email)的函数，然后在表单提交时调用该函数，就像这样

function validateEmail(email){
  // code
}

// Call function on form submission
$('#myform').submit(function() {
   validateEmail($("#txtEmail").val());
})

现在我有这段代码，它对我来说工作得很好，但它使.submit()函数过于混乱，我需要使函数更可重用。

$(document).ready(function() {  
function ValidateEmail(email) {
        var expr = /^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/;
        return expr.test(email);
    };

$('#myform').submit(function() {
var abort = false;  
        if (!ValidateEmail($("#txtEmail").val())) {
            $(this).parent().after('<div class="err"> Valid Email Adress Requierd</div>');
            abort = true;
        }
     if (abort) { return false; } else { return true; }
    })//on submit
}); // ready

这是表单的一个工作示例

$(document).ready(function() {  
    function ValidateEmail(obj, email) {
        var expr = /^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/;
        var testedEmail = expr.test(email);

        var abort = false;  
        if (!testedEmail) {
            $(obj).parent().after('<div class="err"> Valid Email Adress Requierd</div>');
            abort = true;
        }

            if (abort) { return false; } else { return true; }    
    } 

    $('#myform').submit(function() {
        return ValidateEmail(this, $("#txtEmail").val())
    });

}); // ready

这是我的演示。

尝试这个：

var __REGEXINT__ = '__REGEXINT__',

var __REGEXCEP__ = '__REGEXCEP__';

var __REGEXMAIL__ = '__REGEXMAIL__';

var validator = {

    _targetErrors : '#sectionErrors',

    setError: function(msg){

        var message = '<p>{message}</p>'.replace('{message}', msg);

        $(this._targetErrors).append(message)
    },

    __renderInputs : function(__inputs__){


        function __getValueOfTarget(target, delimitator){

            if(!target)
                return false;

            if(typeof target == "string")

                return $(target).val();

            else if(typeof target == "object"){

                var _return_ = [];

                if(!delimitator)
                    delimitator = '';

                for(var id in target)
                    _return_.push(__getValueOfTarget(target[id]));


                return _return_.join(delimitator);
            }

            return false;
        }

        var __return__ = {};
        var __error__ = false;

        for(name in __inputs__){

            var input = __inputs__[name];
            var value = __return__[name] = __getValueOfTarget(input.target, input.delimitator);
            var foundError = false;
            if(!input.validator){

                __return__[name] = value;
