Question

I am validating two sections of a webpage the first validation section validates however the second validator is not for some reason.

$(function(){



/* first validation - works*/
jVal = {
    //validate firstName
    'firstName': function(){

        //appends #firstNameInfo with .info to body
        $('body').append('<div id="firstNameInfo" class="info"></div>');

        //create variables
        var firstNameInfo = $('#firstNameInfo');
        var ele = $('#firstName');

        var patt = /^[a-zA-Z][a-zA-Z]{1,20}$/; 

        if(!patt.test(ele.val())) {
            jVal.errors = true;
            firstNameInfo.removeClass('correct').addClass('error');
            ele.removeClass('normal').addClass('wrong');
        }else{
            firstNameInfo.removeClass('error').addClass('correct');
            ele.removeClass('wrong').addClass('normal');
        }
    },

    //validate lastName
    'lastName': function() {

        $('body').append('<div id="lastNameInfo" class="info"></div>');

        var lastNameInfo = $('#lastNameInfo');
        var ele =$('#lastName');

        var patt = /^[a-zA-Z][a-zA-Z]{1,20}$/;

        if(!patt.test(ele.val())){
            jVal.errors = true;
                lastNameInfo.removeClass('correct').addClass('error');
                ele.removeClass('normal').addClass('wrong');
        }else{
            lastNameInfo.removeClass('error').addClass('correct');
            ele.removeClass('wrong').addClass('normal');
        }
    },
    //validate phone

    'phone' : function(){
        $('body').append('<div id="phoneInfo" class="info"></div>');

        var phoneInfo = $('#phoneInfo');
        var ele = $('#phone');

        var patt = /^((\+?1-)?\d\d\d-)?\d\d\d-\d\d\d\d$/;

        if(!patt.test(ele.val())) {
            jVal.errors = true;
            phoneInfo.removeClass('correct').addClass('error');
            ele.removeClass('normal').addClass('wrong');
        }else{
            phoneInfo.removeClass('error').addClass('correct');
            ele.removeClass('wrong').addClass('normal');
        }
    },

    //validate zipcode 
    'zip' : function() {
        $('body').append('<div id="zipInfo" class="info"></div>');

        var zipInfo = $("#zipInfo");
        var ele = $('#content_form #zip');

        var patt = /^\d\d\d\d\d$/;

        if(!patt.test(ele.val())){
            jVal.errors = true;
                zipInfo.removeClass('correct').addClass('error');
                ele.removeClass('normal').addClass('wrong');
        }else{
            zipInfo.removeClass('error').addClass('correct');
            ele.removeClass('wrong').addClass('normal');
        }
    },
    //submit button code
    'sendForm':function(){
        if(!jVal.errors){
            $('#content_form').submit();
        }
    },
};

$('#content_form #submit').click(function(){
    var obj = $.browser.webkit ? $('body') : $('html');
    jVal.errors = false;
    jVal.firstName();
    jVal.lastName();
    jVal.phone();
    jVal.zip();
    jVal.sendForm();

return false;

$('#firstName').change(jVal.firstName);
$('#lastName').change(jVal.lastName);
$('#email').change(jVal.email);
$('#content_form #zip').change(jVal.zip);

});

/**** Second Validation Does Not work ******/

kVal ={

    'zip' : function() {
        $('body').append('<div id="Infozip" class="info"></div>');

        var Infozip = $("#Infozip");
        var ele = $('#form #zip');

        var patt = /^\d\d\d\d\d$/;

            kVal.error = true;
                Infozip.removeClass('correct').addClass('error');

    kVal.errors = false;
    kVal.zip();
    kVal.send();

return false;


$('#form #zip').change(kVal.zip);
});


}); /*main function closer*/

HTML FOR FIRST Validation -WORKING –

<div id="content_form">
            <p>
                <label class="block">
                    <input type="text" id="firstName" type="firstName" autocomplete="on" value="first name">

HTML FOR SECOND Validation

            </p>        
        </div><!-- end form -->

Answer 1

You have the same id on both zip fields, which is probably causing your problems. The docs for the jQuery #id selector has this to say;

Each id value must be used only once within a document. If more than
one element has been assigned the same ID, queries that use that ID
will only select the first matched element in the DOM. This behavior
should not be relied on, however; a document with more than one
element using the same ID is invalid.

That is, your selection in $('#form #zip').change(kVal.zip); will not use the hierarchy under #form to find #zip, it will still find the first instance in the entire DOM.
