如何单击使用<；创建的按钮；span>；SeleniumWebDriver的标签？

我有一个span标签，看起来像html标签上的一个按钮

    <span class="middle">Next</span>

使用绝对值

xpath=driver.findElement(By.xpath("html/body/div[4]/div[2]/a/span/span/span"));  // took this from firebug

和使用

driver.findElement(By.cssSelector("span[class='middle']"));

没有成功！！它引发以下异常：

线程“main”org.openqa.selenium.NoSuchElementException中出现异常：找不到元素：{“方法”：“xpath”，“选择器”：”//span[包含（，，\“下一步\”）]“} 命令持续时间或超时：30.12秒 有关此错误的文档，请访问：

对于我尝试的所有方法，它都显示了相同的异常，选择器细节发生了变化。有人能帮我找到解决方案吗？这样我就可以在span标签中找到下一个按钮并单击它

下一个按钮位于iFrame中：下面是html的一部分，包含所需的span标记

下一个 我还尝试了：

driver.switchTo().frame("iframe-applicationname_ModalDialog_0");
WebElement el = driver.findElement(By.cssSelector("span.middle"));

但有以下错误：

原因：org.openqa.selenium.ElementNotVisibleException:元素当前不可见，因此可能无法与之交互

如果需要我缺少的东西，请告诉我。

试试这个

driver.findElement(By.xpath("//span[contains(@class,'middle') and contains(text(), 'Next')]"))

试试这个

driver.findElement(By.xpath("//span[contains(@class,'middle') and contains(text(), 'Next')]"))

我认为该元素位于帧或iframe内，如果是，则需要在查找元素之前切换该帧或iframe，如下所示：-

driver.switchTo().frame("iframe-applicationname_ModalDialog_0");
WebElement el = driver.findElement(By.cssSelector("span.middle"));
el.click();

//Now after all your stuff done inside frame need to switch to default content 
driver.switchTo().defaultContent();

 WebDriverWait wait = new WebDriverWait(driver, 10);

//Find frame or iframe and switch
wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("iframe-applicationname_ModalDialog_0"));

//Now find the element 
WebElement el = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(".//span[@class = 'middle' and contains(text(), 'Next')]")));
el.click();

//Once all your stuff done with this frame need to switch back to default
driver.switchTo().defaultContent();

WebDriverWait wait = new WebDriverWait(driver, 10);

//Find frame or iframe and switch
wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("iframe-applicationname_ModalDialog_0"));

//Now find the element 
WebElement el = wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath(".//span[@class = 'middle' and contains(text(), 'Next')]")));

//Now click using JavascriptExecutor
((JavascriptExecutor)driver).executeScript("arguments[0].click()" el); 

//Once all your stuff done with this frame need to switch back to default
driver.switchTo().defaultContent();

Edited1：-如果由于元素当前不可见而出现异常，则需要实现

WebDriverWait

以等待元素可见，如下所示：-

driver.switchTo().frame("iframe-applicationname_ModalDialog_0");
WebElement el = driver.findElement(By.cssSelector("span.middle"));
el.click();

//Now after all your stuff done inside frame need to switch to default content 
driver.switchTo().defaultContent();

 WebDriverWait wait = new WebDriverWait(driver, 10);

//Find frame or iframe and switch
wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("iframe-applicationname_ModalDialog_0"));

//Now find the element 
WebElement el = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(".//span[@class = 'middle' and contains(text(), 'Next')]")));
el.click();

//Once all your stuff done with this frame need to switch back to default
driver.switchTo().defaultContent();

WebDriverWait wait = new WebDriverWait(driver, 10);

//Find frame or iframe and switch
wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("iframe-applicationname_ModalDialog_0"));

//Now find the element 
WebElement el = wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath(".//span[@class = 'middle' and contains(text(), 'Next')]")));

//Now click using JavascriptExecutor
((JavascriptExecutor)driver).executeScript("arguments[0].click()" el); 

//Once all your stuff done with this frame need to switch back to default
driver.switchTo().defaultContent();

Edited2：-如果不幸无法看到，请尝试使用

JavascriptExecutor

单击它，如下所示：-

driver.switchTo().frame("iframe-applicationname_ModalDialog_0");
WebElement el = driver.findElement(By.cssSelector("span.middle"));
el.click();

//Now after all your stuff done inside frame need to switch to default content 
driver.switchTo().defaultContent();

 WebDriverWait wait = new WebDriverWait(driver, 10);

//Find frame or iframe and switch
wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("iframe-applicationname_ModalDialog_0"));

//Now find the element 
WebElement el = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(".//span[@class = 'middle' and contains(text(), 'Next')]")));
el.click();

//Once all your stuff done with this frame need to switch back to default
driver.switchTo().defaultContent();

WebDriverWait wait = new WebDriverWait(driver, 10);

//Find frame or iframe and switch
wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("iframe-applicationname_ModalDialog_0"));

//Now find the element 
WebElement el = wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath(".//span[@class = 'middle' and contains(text(), 'Next')]")));

//Now click using JavascriptExecutor
((JavascriptExecutor)driver).executeScript("arguments[0].click()" el); 

//Once all your stuff done with this frame need to switch back to default
driver.switchTo().defaultContent();

试试这个

new WebDriverWait(driver, 30).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[contains(@class,'middle') and contains(text(), 'Next')]"))).click();

试试这个

new WebDriverWait(driver, 30).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[contains(@class,'middle') and contains(text(), 'Next')]"))).click();

我试过了，它对我有效：

WebElement actionBtn=driver2.findElement(
  By.xpath("//span[contains(@class,'v-menubar-menuitem-caption')
  and contains(text(), 'Actions')]")
);
actionBtn.click();

CSS选择器看起来不错。验证xpath：使用firefox手动打开页面。按F12打开开发工具并切换到控制台。键入

$x（“//span[@class='middle']”）。length

查看有多少元素与该Xpath匹配。如果Selenium找不到它，则可能是看错了窗口或帧。我可以看到计数为0。但当我右键单击Next按钮并检查元素时，我可以看到上面提到的Next和xpath。我怎样才能解决这个问题？你是在找frame还是iframe？？该元素可能位于任何框架或iframe内？？验证一下。你能发布准确的HTML代码吗？只添加HTML的一部分，CSS选择器看起来不错。验证xpath：使用firefox手动打开页面。按F12打开开发工具并切换到控制台。键入
