jQWidgets jqxDataTable autoShowLoadElement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jqx数据表用于读取和显示来自的数据HTML 表格。这也用于显示来自各种数据源的数据，例如XML,JSON， 大批，CSV 或 TSV.

自动显示加载元素属性用于设置或返回与动态 gif 一起加载的 HTML 元素是否在整个数据绑定过程中借助小部件自发显示。布尔类型，默认值为“true”。

用法:

  • 设置自动显示加载元素属性。
$('Selector').jqxDataTable({ autoShowLoadElement: false });
  • 返回自动显示加载元素属性。
var autoShowLoadElement = 
    $('Selector').jqxDataTable('autoShowLoadElement');
