jQWidgets jqxValidator updatePosition()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。 jqxValidator 用于在 JavaScript 的帮助下验证 HTML 表单。它根据用户输入验证的要求，有一组内置规则，e-mail、SSN、ZIP、最大值、最小值、间隔等。这里还可以根据具体情况编写自定义规则要求。

updatePosition() 方法用于更新指定 jqxvalidator 的所有提示的位置。此方法在调整当前窗口大小时很有用。

用法:

$('#jqxValidator').jqxValidator('updatePosition');

Parameters: 该方法不接受任何参数。

返回值：该方法不返回任何值。

链接文件：下载jQWidgets从给定的链接。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.js”></script>
<script type=”text/javascript” src=”jqwidgets/jqxcore.js”></script>
<script type=”text/javascript” src=”jqwidgets/jqxvalidator.js”></script>

例子：下面的例子说明了 jQWidgetsupdatePosition()方法。在下面的示例中，运行代码后，当前窗口的大小已调整，这就是提示位置已更改的原因。所以在调用之后updatePosition()方法中，所有提示的位置都会更新为其默认位置。
