jQWidgets jqxGrid source属性用法及代码示例


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。这江青网格用于说明以表格形式显示数据的 jQuery 小部件。此外，它还全面支持数据连接、分页、分组、排序、过滤和编辑。

资源 属性用于定义显示的jqxGrid的来源。它是对象类型，默认值为{}。

源对象表示的一些键/值对如下：

  • url:它是包含在字符串中的指定 URL，请求将发送到该字符串。
  • data:这是要向服务器方向发送的指定数据。
  • localdata:它是用于指向本地数据源的指定数据数组或数据字符串。
  • datatype:它是指定的数据类型，其中可用值为‘xml’, ‘json’, ‘jsonp’, ‘tsv’, ‘csv’, ‘local’, ‘array’ 和‘observablearray’。
  • type:这是要发出的指定类型的请求，其中可能的值为“POST” 或“GET”，默认值为“GET”。
  • id:它是指定的 id 数据字段，其类型为字符串。
  • root:它是说明数据从哪里开始以及从该元素开始的所有不同循环的指定根。它是字符串类型。
  • record:它是说明特定记录的信息的陈述记录。它是字符串类型。

用法:

  • 设置资源 属性。
$('Selector').jqxGrid({ source: {} });
  • 返回资源 属性。
var source = $('selector').jqxGrid('source');
