如何在 select2 字段下进行 jquery 验证 - 我尝试了一切

Question

I have a problem with select2 and Jquery and Checkboxes. I made a form with some different fields. The validate warning is showed above Select field when I added the validate of checkboxes. When I did not add this code:

[checkboxes validate code][1]

Answer 1

You can try this:

<form id="myForm" method="post" name="myForm" action="">
    <div class="checkbox-container">
        <label for="terms">terms : </label>
        <input type="checkbox" name="terms" id="terms">
        <div id="errorToShow"></div>
    </div>
    <button type="submit">save</button>
</form>

Script:

       $("#myForm").validate({
            rules: {
                terms: "required"
            },
            messages: {
                terms: "select the checkbox"
            },
            errorPlacement: function(error, element) {
                if (element.attr("name") == "terms") {
                    error.appendTo("#errorToShow");
                } else {
                    error.insertAfter(element);
                }
            }
        });

Place the contains id="errorToShow" where you want to show error. This works for me. The error message will be shown in

<div id="errorToShow"></div>

Answer 2

Thank you for your answer. So I do it a little different. The validation code is now:

                $("#signupForm").validate({
                    debug: false,
                    errorClass: "has-error",
                    errorElement: "span",
                   rules: {

                        miejscowosc: {
                            required: true,
                            lettersonly: true,
                        },
                                               wojewodztwo: {
                            required: true,
                        },


                    errorContainer: $('#errorContainer'),
                    // enabling this will display error labels in the container error
                    // errorLabelContainer: $('#errorContainer ul'),
                    // wrapper: 'li',

                    highlight: function(element, errorClass, validClass) {
                        $(element).addClass(errorClass); //.removeClass(errorClass);
                        $(element).closest('.form-group').removeClass('has-success').addClass('has-error');
                    },
                    unhighlight: function(element, errorClass, validClass) {
                        $(element).removeClass(errorClass); //.addClass(validClass);
                        $(element).closest('.form-group').removeClass('has-error').addClass('has-success');
                    },
                    errorPlacement: function(error, element) {
                        if (element.parent('.input-group').length) {
                            error.insertAfter(element.parent());
                        } else if (element.hasClass('select2')) {
                            error.insertAfter(element.next('span'));
                        } 
                        else if (element.attr("name") == "zgoda") {
                            error.insertAfter("#checkboxError"); 
                            } 

                            else if (element.attr("name") == "zgoda1") {
                            error.insertAfter("#checkboxError1"); 
                            } 
                            else if (element.attr("name") == "zgoda2") {
                            error.insertAfter("#checkboxError2"); 
                            } 

                        else {
                            error.insertAfter(element);
                        }
                    },



                });

and now the warning message is Under select2 so It is Ok.

The code Of select2 is

var Formularz = function () {
                    return {
                        //main function to initiate the module
                        init: function () {
                            function format(state) {
                                if (!state.id) return state.text; // optgroup
                                return state.id.toLowerCase() + state.text;
                            }

                            $("#Select_Wojewodztwo").select2({
                                placeholder: "Wybierz Wojewodztwo",
                                allowClear: true,
                                formatResult: format,
                                width: '100%',  
                                formatSelection: format,
                                escapeMarkup: function (m) {
                                    return m;
                                }
                            });                                     
                        }
                    };
                }();

                jQuery(document).ready(function() {
                    Formularz.init();
                }); 

the second my problem is has-error does not wotk in select2 field and doesnt highlight it on red.

enter image description here

the code in form is:

<div class="col-sm-12 col-md-4 col-lg-4 form-group">                                            
                                        <div class="col-lg-12 form-label">
                                            Województwo
                                        </div>  
                                        <div class="col-lg-12 ">
                                            <select name="wojewodztwo" id="Select_Wojewodztwo" class="select2 form-control selection">

what do you think about it. What can be wrong here?
