jQWidgets jqxForm getComponentByName() 方法

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。 jqxForm 代表一个 jQuery 表单小部件，它包含 textFields、textArea 和密码字段等，可帮助我们将数据存储在应用程序的后端。

getComponentByName()方法用于通过名称获取组件信息。它不返回任何值，并将组件名称作为参数。

句法：

$('Selector').jqxForm(
    'getComponentByName', 'componentName');
