jQuery Bootstrap Select2插件问题与Validate插件 [英] Jquery bootstrap select2 plugin issue with validate plugin

问题描述

在我的引导项目中，我试图使用插件select2，但我意识到 如果您使用此插件，则无法再使用validate插件来验证我的表单中的选择字段. 我会避免使用商业插件引导程序验证器.

In my bootstrap project I'm trying to use the plugin select2 but I realized that if you use this plugin are no longer able to validate select fields in my form with validate plugin. I would avoid using the commercial plugin bootstrap validator..

<div class="container">
<div class="row">
    <form id="test_form" action="?">
        <div class="col-md-3">
            <div class="form-group">
                <label for="name">Foo</label>
                 <select class="form-control" id="foo" name="foo">
                     <option value=""></option>
                     <option value="1">1</option>
                     <option value="2">2</option>
                 </select>
            </div>
        </div>
        <div class="col-md-3">
            <div class="form-group">
                <label for="name">Bar</label>
                <select class="form-control" id="bar" name="bar">
                    <option value=""></option>
                    <option value="1">1</option>
                    <option value="2">2</option>
                </select>
            </div>
        </div>
        <div class="col-md-1">
            <button type="submit" class="btn btn-primary">VALIDATE</button>
        </div>
    </form>
</div>
</div>

JS

/* select 2 plugin */
$('select#foo').select2();

/* Validation */
$("#test_form").validate({
    rules:
    {
        foo: { required: true },
        bar: { required: true }
    },
    errorPlacement: function (error, element) {
        $(element).addClass('err');
    },
    success: function (label, element) {
        $(element).removeClass('err');
    },
    submitHandler: function(form) {
        alert("validation ok");
    }
});

您认为我该如何解决此问题?谢谢

好.这是对我有用的东西

Ok. Here is what worked for me

/* select 2 plugin */
$('select#foo').select2();

/* Validation */
    $("#test_form").validate({
        ignore: 'input[type=hidden]',
        rules:
        {
            foo: { required: true },
            bar: { required: true }
        },
        errorPlacement: function (error, element) {
            $(element).parent().addClass('has-error');
        },
        success: function (label, element) {
            $(element).parent().removeClass('has-error');
        },
        submitHandler: function(form) {
            alert("validation ok");
        }
    });

我添加了一个"ignore:'input [type = hidden]'"选项，因为Select2脚本向原始输入添加了一个隐藏选项，而Jquery Validator似乎忽略了它.然后我将错误类别从元素上的"err"更改为父元素(具有表单组类的div)上的"has-error"

I added a "ignore: 'input[type=hidden]'," option because the Select2 script adds a hidden option to the original input and the Jquery Validator seems to ignore it. Then i changed the error class from "err" on the element to "has-error" on the parent element (the div with form-group class)
