selenium-java 元素一直提示定位不到

悬赏园豆：50 [已解决问题] 解决于 2017-12-20 14:04

seleniuum IDE上抓取的代码，在Java上运行以后一直提示无法定位元素，这个应该怎么解决？（刚学自动化测试，有很多不懂得，望指教）

报错信息：

最佳答案

找不到name_l2这个id，建议通过classname定位试试，再不行用xpath

都试过了，还是不行；看的是跳转到新的页面以后就定位不到元素了

夏末秋至 | 园豆：106 (初学一级) | 2017-12-11 11:27

@夏末秋至: 跳转到新页面要做句柄判断的：

String currentWindow = driver.getWindowHandle();
            Set<String> handles = driver.getWindowHandles();
            Iterator<String> it = handles.iterator();
            while (it.hasNext()) {
                String handle = it.next();
                if (currentWindow.equals(handle))
                    continue;
                driver.switchTo().window(handle);
            }

@ycyzharry: 谢谢，已解决

@ycyzharry: 你好，抱歉，还有一个问题想要问一下，上次说的是跳转到一个新的页面需要做句柄判断，如果是在同一个页面中打开另一个页面（具体如下图），还是提示定位不到元素，这个应该怎么解决？

@夏末秋至: 只要是打开新的窗口就需要做句柄判断

你可以先试试其他定位方法，比如xpath
