有一个简单的方法来改变默认的错误值在jQuery验证插件?

我只是想重写错误消息,以使我的应用程序更加个性化——我有很多字段,所以我不想为字段x单独设置消息……我知道我能做到!

您可以在验证调用中指定自己的消息。从验证插件文档(http://jquery.bassistance.de/validate/demo/milk/)中使用的Remember the Milk注册表单中提升和缩写这段代码,您可以轻松地指定自己的消息:

var validator = $("#signupform").validate({
    rules: {
        firstname: "required",
        lastname: "required",
        username: {
            required: true,
            minlength: 2,
            remote: "users.php"
        }
    },
    messages: {
        firstname: "Enter your firstname",
        lastname: "Enter your lastname",
        username: {
            required: "Enter a username",
            minlength: jQuery.format("Enter at least {0} characters"),
            remote: jQuery.format("{0} is already in use")
        }
    }
});

@Josh:你可以从你的资源包中翻译消息来扩展你的解决方案

<script type="text/javascript">
    $.validator.messages.number = '@Html.Raw(@Resources.General.ErrorMessageNotANumber)';
</script>

如果你把这段代码放到你的_Layout中。cshtml (MVC),它可用于所有视图

jQuery表单验证自定义错误消息-tutsmake

Demo

$(document).ready(function(){ $("#registration").validate({ // Specify validation rules rules: { firstname: "required", lastname: "required", email: { required: true, email: true }, phone: { required: true, digits: true, minlength: 10, maxlength: 10, }, password: { required: true, minlength: 5, } }, messages: { firstname: { required: "Please enter first name", }, lastname: { required: "Please enter last name", }, phone: { required: "Please enter phone number", digits: "Please enter valid phone number", minlength: "Phone number field accept only 10 digits", maxlength: "Phone number field accept only 10 digits", }, email: { required: "Please enter email address", email: "Please enter a valid email address.", }, }, }); }); <!DOCTYPE html> <html> <head> <title>jQuery Form Validation Using validator()</title> <script src="https://code.jquery.com/jquery-3.1.1.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.19.0/jquery.validate.js"></script> <style> .error{ color: red; } label, input, button { border: 0; margin-bottom: 3px; display: block; width: 100%; } .common_box_body { padding: 15px; border: 12px solid #28BAA2; border-color: #28BAA2; border-radius: 15px; margin-top: 10px; background: #d4edda; } </style> </head> <body> <div class="common_box_body test"> <h2>Registration</h2> <form action="#" name="registration" id="registration"> <label for="firstname">First Name</label> <input type="text" name="firstname" id="firstname" placeholder="John"><br> <label for="lastname">Last Name</label> <input type="text" name="lastname" id="lastname" placeholder="Doe"><br> <label for="phone">Phone</label> <input type="text" name="phone" id="phone" placeholder="8889988899"><br> <label for="email">Email</label> <input type="email" name="email" id="email" placeholder="john@doe.com"><br> <label for="password">Password</label> <input type="password" name="password" id="password" placeholder=""><br> <input name="submit" type="submit" id="submit" class="submit" value="Submit"> </form> </div> </body> </html>

将此代码添加到验证插件后包含的单独文件/脚本中,以覆盖消息,随意编辑:)

jQuery.extend(jQuery.validator.messages, {
    required: "This field is required.",
    remote: "Please fix this field.",
    email: "Please enter a valid email address.",
    url: "Please enter a valid URL.",
    date: "Please enter a valid date.",
    dateISO: "Please enter a valid date (ISO).",
    number: "Please enter a valid number.",
    digits: "Please enter only digits.",
    creditcard: "Please enter a valid credit card number.",
    equalTo: "Please enter the same value again.",
    accept: "Please enter a value with a valid extension.",
    maxlength: jQuery.validator.format("Please enter no more than {0} characters."),
    minlength: jQuery.validator.format("Please enter at least {0} characters."),
    rangelength: jQuery.validator.format("Please enter a value between {0} and {1} characters long."),
    range: jQuery.validator.format("Please enter a value between {0} and {1}."),
    max: jQuery.validator.format("Please enter a value less than or equal to {0}."),
    min: jQuery.validator.format("Please enter a value greater than or equal to {0}.")
});

而不是改变插件源代码,你可以包括一个额外的js文件,格式类似于下载本地化文件夹中的那些,并在加载validation.js后包括那个文件

jQuery.extend(jQuery.validator.messages, {
    required: ...,
    maxlength: jQuery.validator.format(...),
    ...
});
$(function() {

$("#username_error_message").hide();
$("#password_error_message").hide();
$("#retype_password_error_message").hide();
$("#email_error_message").hide();

var error_username = false;
var error_password = false;
var error_retype_password = false;
var error_email = false;

$("#form_username").focusout(function() {

    check_username();
    
});

$("#form_password").focusout(function() {

    check_password();
    
});

$("#form_retype_password").focusout(function() {

    check_retype_password();
    
});

$("#form_email").focusout(function() {

    check_email();
    
});

function check_username() {

    var username_length = $("#form_username").val().length;
    
    if(username_length < 5 || username_length > 20) {
        $("#username_error_message").html("Should be between 5-20 characters");
        $("#username_error_message").show();
        error_username = true;
    } else {
        $("#username_error_message").hide();
    }

}

function check_password() {

    var password_length = $("#form_password").val().length;
    
    if(password_length < 8) {
        $("#password_error_message").html("At least 8 characters");
        $("#password_error_message").show();
        error_password = true;
    } else {
        $("#password_error_message").hide();
    }

}

function check_retype_password() {

    var password = $("#form_password").val();
    var retype_password = $("#form_retype_password").val();
    
    if(password !=  retype_password) {
        $("#retype_password_error_message").html("Passwords don't match");
        $("#retype_password_error_message").show();
        error_retype_password = true;
    } else {
        $("#retype_password_error_message").hide();
    }

}

function check_email() {

    var pattern = new RegExp(/^[+a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/i);

    if(pattern.test($("#form_email").val())) {
        $("#email_error_message").hide();
    } else {
        $("#email_error_message").html("Invalid email address");
        $("#email_error_message").show();
        error_email = true;
    }

}

$("#registration_form").submit(function() {
                                        
    error_username = false;
    error_password = false;
    error_retype_password = false;
    error_email = false;
                                        
    check_username();
    check_password();
    check_retype_password();
    check_email();
    
    if(error_username == false && error_password == false && error_retype_password == false && error_email == false) {
        return true;
    } else {
        return false;   
    }

});

});
