Question

主页面包含300多个链接，点击主页面上的每个链接打开新窗口（当然）与表格。我总是需要来自同一位置的表值，但是...有时（但有时只是）（必要的）表值也是一个链接，在点击它之后打开新窗口。如果单击该表值打开新窗口（使用新表）我需要来自该新窗口的特定表值，否则（如果原始表值不是链接）我只需要原始表值。
我尝试使用下面的代码，但发生错误......

线程中的异常＆＃34; main＆＃34; org.openqa.selenium.NoSuchElementException：无法找到元素：{＆＃34;方法＆＃34;：＆＃34; xpath＆＃34;，＆＃34;选择器＆＃34;：＆＃34; .//* [ @id =＆＃39; aodds-信息＆＃39;] / DIV [2] /表/ tbody的/ TR [3] / TD [2]＆＃34;} 命令持续时间或超时：33毫秒

从NoSuchElementException导入java.util。要捕获Web元素异常，您需要从org.openqa.selenium导入。

作为旁注，使用explicit and implicit wait比使用Thread.sleep要好得多。
