本文整理了Java中org.openqa.selenium.By.className()方法的一些代码示例，展示了By.className()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。By.className()方法的具体详情如下：
包路径：org.openqa.selenium.By
类名称：By
方法名：className

By.className介绍

[英]Find elements based on the value of the "class" attribute. If an element has multiple classes, then this will match against each of them. For example, if the value is "one two onone", then the class names "one" and "two" will match.
[中]根据“class”属性的值查找元素。如果一个元素有多个类，那么这将与每个类匹配。例如，如果值为“one-two-onone”，则类名“one”和“two”将匹配。
