jQWidgets jqxValidator 验证错误事件

jQWidgets是一个 JavaScript 框架，用于为 PC 和移动设备制作基于 Web 的应用程序。它是一个非常强大、经过优化、独立于平台且得到广泛支持的框架。 jqxValidator用于在 JavaScript 的帮助下验证 HTML 表单。根据用户输入验证的要求，它有一些内置规则，电子邮件，SSN，ZIP，最大值，最小值，间隔等。这里也可以根据具体情况编写自定义规则要求。

当表单被验证有一些错误时， validationError事件被触发。

句法：

$('#jqxValidator').on('validationError', function (event) {
    // Code section 
});

链接文件：从给定链接下载 jQWidgets。在 HTML 文件中，找到下载文件夹中的脚本文件。

示例：下面的示例说明了 jQWidgets validationError 事件。
