极客教程jQWidgets jqxDataTable exportSettings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、并被广泛支持的框架。jqxDataTable是用来读取和显示HTML表的数据的。这也被用来显示来自各种数据源的数据，如XML、JSON、Array、CSV或TSV。
exportSettings属性用于设置或返回显示的jqxDataTable在调用exportData方法时使用的数据的导出设置。它是对象类型，其默认值是{ columnsHeader: true, hiddenColumns: false, serverURL: null, characterSet: null, recordsInView: true, fileName:"jqxDataTable"}。
这里使用的参数列表如下。
- columnsHeader。它用于确定列的标题是否要被导出。
- hiddenColumns:它用于确定是否要导出隐藏列。
- serverURL。它用于确定服务器的URL。
- characterSet。它用于确定字符集。
- recordsInView。它用于确定是否要导出所有的记录，或者过滤以及排序也要考虑在内。
- fileName。它用于确定文件的名称。
语法:
设置exportSettings属性。
$('Selector').jqxDataTable({
exportSettings: { hiddenColumns: true }
});
返回exportSettings属性。
var exportSettings =
$('Selector').jqxDataTable('exportSettings');
