【问题标题】：Unable to click button which is inside iframe and table in Selenium webDriver with c#无法使用 c# 在 Selenium webDriver 中单击 iframe 和表格内的按钮
【发布时间】：2018-04-04 16:03:37
【问题描述】：

我是 c# 新手，我正在 c# 中使用 Selenium chrome webdriver。我正在尝试单击表格内的按钮。我无法识别并单击按钮。按钮的层次结构是（Page > PopOver > PopOverFrame > Table1 > Table2 > Button to click ）

对此的任何帮助将不胜感激。

我的代码是：

          */
        // Closing old tab, keeping control in new tab and trying to perform click operation
        var currentWindow = BaseTest.Driver.CurrentWindowHandle;
        var availableWindows = new List<string>(BaseTest.Driver.WindowHandles);

        foreach (string mywindows in availableWindows)
            {

            if (mywindows != currentWindow)
                {
                Driver.SwitchTo().Window(mywindows).Close();
                }
            else
                {
                Driver.SwitchTo().Window(currentWindow);

                // performing click action on RUN REPORT button

                IWebElement popOver = Driver.FindElement(By.Id("popOver"));
                IWebElement popOverFrame = popOver.FindElement(By.Id("popOverFrame"))
                IWebElement table1 = popOverFrame.FindElement(By.XPath("//*[@id='form1']/table"));
                IWebElement Table2 = table1.FindElement(By.XPath("//*[@id='tblReport']"));
                Table2.FindElement(By.Id("contentPlaceholder_btnPrint")).Click();
                }
            }

Please refer to attached screenshot of what html page looks like.

【问题讨论】：

如果您只是复制 html 代码而不是照片会很有帮助。
您好 Hashim77，我添加了 html 代码。感谢您的帮助

标签： c# selenium selenium-webdriver c#-4.0 selenium-chromedriver

【解决方案1】：

试试这个：

//remove this line IWebElement popOver = Driver.FindElement(By.Id("popOver"));
Driver.SwitchTo().DefaultContent();
IWebElement popOverFrame = Driver.FindElement(By.Id("popOverFrame"))
Driver.SwitchTo().Frame(popOverFrame);
//remove this line IWebElement table1 = popOverFrame.FindElement(By.XPath("//*[@id='form1']/table"));
IWebElement Table2 = Driver.FindElement(By.XPath("//*[@id='tblReport']"));
Table2.FindElement(By.Id("contentPlaceholder_btnPrint")).Click();

【讨论】：

答案的原因是，大多数带有iframe的页面都需要切换到才能与之交互。因此，您将首先切换到默认内容，然后再切换到层次结构中的第一个 iframe。
谢谢你为我工作的哈希姆。非常感谢您的帮助

【解决方案2】：

试试下面的一个：

driver.switchTo().frame(driver.findElement(By.xpath(iframeXpath)));

一旦在 iFrame 内完成操作，切换回默认内容。

driver.switchTo().defaultContent();
