Question

无法在IE浏览器上看到iframe：9浏览器虽然存在框架，但同一页面能够识别Firefox浏览器上的框架。当 driver.switchTo（）。frame（＆＃34; frMiftButton＆＃34;）; 添加到脚本中时，看到错误＆＃39;当前关注窗口已关闭＆＃39;

package eHMS_package;

import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;


public class HMS_Login_entry_Frame {

    public WebDriver driver;

    public static void main(String[] args) throws Exception{

        System.setProperty("webdriver.ie.driver","D:/SRIKANTH/IEDriverServer_32bit/IEDriverServer.exe");
        InternetExplorerDriver driver=new InternetExplorerDriver();
        driver.manage().window().maximize();
        driver.navigate().to("http://10.1.0.20:8080/JHMS/login.faces");
        driver.findElement(By.id("frmLogin:txtUserName")).sendKeys("makella");
        driver.findElement(By.id("frmLogin:txtPassword")).sendKeys("sriram");
        driver.findElement(By.name("frmLogin:login")).click();
        driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);

        int size = driver.findElements(By.xpath("//iframe")).size();

        System.out.println("Total Frames --" + size);
        // prints the total number of frames 

        driver.switchTo().frame("frMiftButton"); 
        System.out.println (driver.findElement(By.xpath("/html/body/form/table/tbody/tr/td[3]/div")).getText()); 

    }
}

您需要考虑以下几点：

当您使用 Selenium ，InternetExplorerDriver和 Internet Explorer 时，您必须按照Required Configuration强制设置环境。
当您看到总帧数--0 时，可能没有帧通过 Internet Explorer 9浏览器呈现。此时值得一提的是，不同的浏览器以不同的方式呈现HTML DOM。在这种情况下，您可能需要使用项目管理来解决设计/架构问题。
如果您确定在浏览手动粗略时可以使用框架 frMiftButton ，那么您正试图检测框架并过早切换。在您调用click()的上一行中，您应该在新页面上引导 WebDriverwait 以使目标 frame 可用于切换，并且您必须切换通过 frameID ， framename 等，如下所示：
```
new WebDriverWait(driver, 10).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.id("frMiftButton")));
// or
new WebDriverWait(driver, 10).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.name("frMiftButton")));
```
您正在使用 Selenium Java Client v3.9.1 和 IEDriverServer v3.9.0.0 。 IEDriverServer v3.9.0.0 存在一个主要问题，您可以在Selenium Java Client (v3.9.1) with IEDriverServer v3.9.0.0 (64-bit) crashes with org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:28286中找到详细讨论。在这种情况下，您需要使用最新的 IEDriverServer v3.11.1

＆＃34; org.openqa.selenium.NoSuchWindowException：当前关注的窗口已关闭＆＃34;同时尝试在IE9浏览器中切换到（）。frame（）
