Question

我一直在尝试制作一个验证电话号码和姓名的表单，但无论何时输入提交，它都会输入相同的消息，无论字段是否已填写。消息不断出现，我无法弄清楚

<body>
<form id="contact">
<fieldset id="contactInformation">
<legend>Contact Information</legend>
<p id="error"></p>
<label id="name">Name:</label>
<br>
<input type="text">
<br>
<br>
<label id="phoneNumber">Phone Number:</label>
<br>
<input type="text">
<br>
<br>
<label id="eMail">E-Mail Address:</label>
<br>
<input type="text">
<br>
<br>
<label id="address">Address:</label>
<br>
<input type="text">
<br>
<br>
<label id="city">City:</label>
<br>
<input type="text">
<br>
<br>
<label id="postalCode">Postal Code:</label>
<br>
<input type="text">
<br>
<br>
<label id="province">Province</label>
<br>
<select id="province">
<option id="choose">Choose Your Province</option>
<option id="alberta">Alberta</option>
<option id="britishColumbia">British Columbia</option>
<option id="manitoba">Manitoba</option>
<option id="newBrunswick">New Brunswick</option>
<option id="newfoundland">Newfoundland and Labrador</option>
<option id="northwestTerritories">Northwest Territories</option>
<option id="noviaScotia">Nova Scotia</option>
<option id="nunavut">Nunavut</option>
<option id="ontario">Ontario</option>
<option id="pei">Prince Edward Island</option>
<option id="quebec">Quebec</option>
<option id="saskatchewan">Saskatchewan</option>
<option id="yukon">Yukon Territory</option>
<br>
<br>
<br>
<label id="shippingCheckbox">Is your shipping information the same as your contact information?
<input type="radio" id="sameInfo">
<label>
Yes it is
</label>
<br>
<br>
<input type="radio" id="notSameInfo">
<label>
No it is not
</label>
<br>
<br>
<input type="submit" id="submit" name="submit" value="Submit">
</form>
<br>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script src="js/script.js"></script>
</body>
</html>

以下是剧本：

//script.js
var errorNotify = 'Sorry, we could not process your request because '
var errorField = [];

function formVal() {
    var isValid = true;

    for (var i = 0; i < errorField.length; i++ ) {
        $(errorField[i]).removeClass('error');
    }
    errorField = [];

    if(!nameCheck()) {
        isValid = false;
    }
    if(!phoneCheck()) {
        isValid = false;
    }
    if (isValid === false) {
        $('#error').html(errorNotify).hide().slideDown('slow');
        for (var i = 0; i < errorField.length; i++) {
            $(errorField[i]).addClass('error');
        }
        errorNotify = 'Sorry, we could not process your request because ';
    }

    function nameCheck(){
        if ($('#name').val() === '') {
            errorNotify += ' you did not enter your name.';
            errorField.push($('#name'));
            return false;
        } else {
            return true;
        }
    }
    function phoneCheck(){
        var phoneCheck = $('#phoneNumber').val();
        if (phoneCheck === '') {
            errorNotify += ' you did not enter your phone number.';
            errorField.push($('#phoneNumber'));
            return false;
        } else if (phoneCheck.length !== 10) {
            errorNotify += 'please enter a 10 digit phone number';
            errorField.push($('#phoneNumber'));
        }
        else if (isNaN(parseInt(phoneCheck))) {
            errorNotify += 'you have entered a letter, please enter a number';
            errorField.push($('#phoneNumber'));
        }
        else {
            return true;
        }
    }
    return isValid;
}
$(function () {
    $('#contact').submit(function() {
        return formVal();
    });
});

Answer 1

您在标签标签上有您的ID，而不是输入字段，请更改

<label id="name">Name:</label>
<br>
<input type="text">

到

<label for="name">Name:</label>
<br>
<input id="name" type="text">

等

表单验证不适用于电话号码/名称
