java - 如何解决 "stale element reference: element is not attached to the page document when navigating to the previous page"

Question

我的页面上有图标，该图标可能会在该页面上多次出现。我想单击该图标，截取屏幕截图，然后返回上一页并单击其他图标并执行相同的操作:我得到

stale element reference: element is not attached to the page document

导航到上一页时”。下面是我的代码:

List<WebElement> List = driver.findElements(Loc_AttachmentIcon);

for (WebElement e : List) {             
    if(e.getText().contains(".JPG")) {
        e.click();  
        File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
        // Now you can do whatever you need to do with it, for example copy somewhere
        FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));
        driver.navigate().back();
    }

    else if(e.getText().contains(".jpg")) {
        System.out.println("Contains Jpg file");
    }
    else if(e.getText().contains(".png")) {
        System.out.println("Contains Jpg file");
    }
    else if(e.getText().contains(".PNG")) {
        System.out.println("Contains Jpg file");
    }
    else if(e.getText().contains(".gif")) {
        System.out.println("Contains Jpg file");
    }
    else if(e.getText().contains(".GIF")) {
        System.out.println("Contains Jpg file");
    }
    else {
        e.click();
    }
}

您需要在每次迭代中重新定位元素。您可以使用索引来跟踪您的进度

int size = driver.findElements(Loc_AttachmentIcon).size();

for (int i = 0 ; i < size ; i++) {
    List<WebElement> list = driver.findElements(Loc_AttachmentIcon);
    WebElement e = list.get(i);

    if(e.getText().contains(".JPG")) {
        //...
    }
}
