使用Parsley.js验证选择多选 [英] Validate Chosen Multi Selection with Parsley.js

问题描述

我设法使 parsleyjs.org 验证必需选择下拉列表，但我似乎无法验证多选择下拉列表。

I managed to get parsleyjs.org validate a "required" Chosen dropdown but I can't seem to be able to validate the Multi selection dropdown.

我试图应用最大和最小验证规则，这并不奏效。

I have tried to apply the max and min validation rules, that did not work.

我在测试网站上设置了parsleyjs.org和Choosen： http://loai.directory/test/test/blank.php

I have setup parsleyjs.org and Choosen on a test site here: http://loai.directory/test/test/blank.php

如何在多个文件中验证最小和最大选择dropdwon与parsleyjs？

How can I validate min and max on a multi selection dropdwon with parsleyjs?

推荐答案

您应该使用 data-parsley-mincheck 为此。以下示例按预期工作（ jsfiddle演示 ）。

You should use data-parsley-mincheck for that. The following example works as expected (jsfiddle demo).

<form id="myForm">
    <select name="[]" multiple="multiple" data-parsley-required data-parsley-mincheck="2">
        <optgroup label="Section">
            <option>Drop Down Option A</option>
            <option>Drop Down Option B</option>
        </optgroup>
        <optgroup label="Section">
            <option>Drop Down Option A</option>
            <option>Drop Down Option B</option>
        </optgroup>
    </select>

    <input type="submit" />
</form>

<script>
$(document).ready(function() {
    $("select").chosen();

    $("#myForm").parsley();
});
</script>
