jQWidgets jqxGrid源属性

jQWidgets jqxGrid源属性

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。它是一个非常强大的,优化的,与平台无关的,并且被广泛支持的框架。jqxGrid用来说明一个jQuery widget,以表格形式显示数据。此外,它完全支持与数据的连接,以及分页、分组、排序、过滤和编辑。

source 属性用于定义显示的jqxGrid的来源。它是对象类型的,其默认值是{}。

源对象所代表的一些键/值对如下。

  • url。它是由一个字符串所包含的陈述的URL,其中请求被发送到这个URL。
  • data。它是要向服务器方向发送的所述数据。
  • localdata。它是所述的数据数组或数据字符串,用于指向本地数据的来源。
  • datatype。它是所述的数据类型,可用的值是 “xml”、”json”、”jsonp”、”tsv”、”csv”、”local”、”array “和 “obsablearray”。
  • type。这是声明的请求类型,可能的值是 “POST “或 “GET”,默认值是 “GET”。
  • id。它是所述的id数据字段,属于字符串类型。
  • root。它是陈述的根,描述数据从哪里开始,以及从这个元素开始的所有不同的循环。它的类型是字符串。
  • record。它是陈述的记录,描述了特定记录的信息。它的类型是字符串。

语法:

  • 设置source属性。
$('Selector').jqxGrid({ source: {} });
  • 返_source属性。
var source = $('selector').jqxGrid('source');
