jQWidgets jqxForm getComponentByName()用法及代码示例

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、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，其中包含文本字段、文本区域和密码字段等，这有助于我们在应用程序的后端存储数据。

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

用法:

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