极客教程jQWidgets jqxDataTable 本地化属性
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。
localization属性用于对显示的jqxDataTable的字符串应用本地化。它是对象类型的，其默认值是default localization strings 。
语法:
- 设置localization属性。
$('Selector').jqxDataTable({
localization: default localization strings,
});
- 返回localization属性。
var localization = $('Selector').jqxDataTable('localization');
链接的文件：从给出的链接中下载jQWidgets。在HTML文件中，找到下载文件夹中的脚本文件。
<link rel=”stylesheet” href=”jqwidgets/styles/jqx.base.css” type=”text/css” />
<script type=”text/javascript” src=”scripts/jquery-1.11.1.min.js”></script>
<script type=”text/javascript” src=”jqwidgets/jqxcore.js”></script>
<script type=”text/javascript” src=”jqwidgets/jqxdata.js”></script>
<script type=”text/javascript” src=”jqwidgets/jqxbuttons.js”></script>
<script type=”text/javascript” src=”jqwidgets/jqxscrollbar.js”></script>
<script type=”text/javascript” src=”jqwidgets/jqxlistbox.js”></script>
<script type=”text/javascript” src=”jqwidgets/jqxdropdownlist.js”></script>
<script type=”text/javascript” src=”jqwidgets/jqxdatatable.js”></script>
步骤:
- 添加所有需要的链接到JavaScript文件。
- 在下面的例子中，一个HTML div元素被创建在所述HTML文档的body部分，id=”jqxdt”。
- 在源和列属性的帮助下，小组件显示的数据表被初始化。此外，localization属性被说明了，其中与pagerRangeString有关的本地化对象被设置为’total-‘。
例子1：下面的例子说明了jQWidgets中jqxDataTable localization属性。

("#jqxbtn").on("click", function () {
var ls =('#jqxdt').jqxDataTable('localization');
$("#log").text(ls.pagerRangeString)
});
});
</script>
</body>
</html>
输出:
例子2：下面是jQWidgets中jqxDataTable localization 属性的另一个例子。localization属性被设置为 “null”，所以没有一个字符串被本地化，并且 “null “被作为输出返回。
