jQWidgets jqxValidator updatePosition()用法及代碼示例

jQWidgets 是一個 JavaScript 框架，用於為 PC 和移動設備製作基於 Web 的應用程序。它是一個非常強大、優化、獨立於平台且得到廣泛支持的框架。 jqxValidator 用於在 JavaScript 的幫助下驗證 HTML 表單。它根據用戶輸入驗證的要求，有一組內置規則，e-mail、SSN、ZIP、最大值、最小值、間隔等。這裏還可以根據具體情況編寫自定義規則要求。

updatePosition() 方法用於更新指定 jqxvalidator 的所有提示的位置。此方法在調整當前窗口大小時很有用。

用法:

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

Parameters: 該方法不接受任何參數。

返回值：該方法不返回任何值。

<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：下麵的例子說明了 jQWidgetsupdatePosition()方法。在下麵的示例中，運行代碼後，當前窗口的大小已調整，這就是提示位置已更改的原因。所以在調用之後updatePosition()方法中，所有提示的位置都會更新為其默認位置。
