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 HTML Table 数据。它还用于显示来自各种数据源(例如 XML、JSON、Array、CSV 或 TSV)的数据。
isBindingCompleted()方法用于检查绑定是否完成。如果输出为 true,则可以调用方法并设置属性。但是,如果输出为 false 并且调用了方法或设置了属性,则小部件将引发异常。它没有参数。它返回一个布尔值。
用法:
var isCompleted = $("#Selector") .jqxDataTable('isBindingCompleted');
