本文共计1094个文字，预计阅读时间需要5分钟。

本文整理了Java中com.google.gwt.dom.client.AnchorElement.is()方法的一些代码示例，展示了如何使用该方法检查锚点元素的一些特性。

示例1：检查锚点元素是否有href属性javaAnchorElement anchor=DOM.createAnchor().setHref(http://example.com);boolean hasHref=anchor.is();

示例2：检查锚点元素是否有一个有效的href属性javaAnchorElement anchor=DOM.createAnchor().setHref(http://example.com);boolean isValidHref=anchor.is();

示例3：检查锚点元素是否是可点击的javaAnchorElement anchor=DOM.createAnchor().setHref(http://example.com);boolean isClickable=anchor.is();

示例4：检查锚点元素是否具有特定的类名javaAnchorElement anchor=DOM.createAnchor().setHref(http://example.com).addClassName(my-class);boolean hasClass=anchor.is();

示例5：检查锚点元素是否处于活动状态javaAnchorElement anchor=DOM.createAnchor().setHref(http://example.com);boolean isActive=anchor.is();
