jQWidgets jqxValidator focus属性用法及代码示例

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。这 jqx验证器 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。自定义规则也可以根据具体情况编写要求。

重点属性用于设置或获取指定的 jqxValidator 是否关注第一个无效输入。该方法接受两个可能的值：真的和错误的.

用法:

用于设置重点属性。

$('#jqxValidator').jqxValidator( { focus: false } );

为了得到重点属性。

var focus = $('#jqxValidator').jqxValidator('focus');
