Selenium webdriver定位iframe里面元素两种方法

以东方财富网登录页面为例:

 

在查找元素过程中,直接通过id或者xpath等找不到元素,查看页面源代码发现元素是属于iframe里,例如:

<div class="wrap_login">
        <iframe class="frame_login" src="https://exaccount.eastmoney.com/home/login?request=%7b%22agentPageUrl%22%3a%22https%3a%2f%2fpassport.eastmoney.com%2fpub%2fLoginAgent%22%2c%22redirectUrl%22%3a%22http%3a%2f%2fwww.eastmoney.com%2f%22%2c%22callBack%22%3a%22LoginCallBack%22%2c%22redirectFunc%22%3a%22PageRedirect%22%2c%22data%22%3a%7b%22domainName%22%3a%22passport.eastmoney.com%22%2c%22deviceType%22%3a%22Web%22%2c%22productType%22%3a%22UserPassport%22%2c%22versionId%22%3a%220.0.1%22%7d%7d"></iframe>
    </div>

以下为了定位到iframe里面元素,有2种方法:

方法一:单独打开iframe网址,直接定位。

复制代码
    @Test
    public void loginTest() throws InterruptedException {

        System.setProperty("webdriver.firefox.bin", "D:\\Program Files\\Mozilla Firefox\\firefox.exe");
        WebDriver driver = new FirefoxDriver();
        driver.get("https://exaccount.eastmoney.com/home/login?request=%7b%22agentPageUrl%22%3a%22https%3a%2f%2fpassport.eastmoney.com%2fpub%2fLoginAgent%22%2c%22redirectUrl%22%3a%22http%3a%2f%2fwww.eastmoney.com%2f%22%2c%22callBack%22%3a%22LoginCallBack%22%2c%22redirectFunc%22%3a%22PageRedirect%22%2c%22data%22%3a%7b%22domainName%22%3a%22passport.eastmoney.com%22%2c%22deviceType%22%3a%22Web%22%2c%22productType%22%3a%22UserPassport%22%2c%22versionId%22%3a%220.0.1%22%7d%7d");  
        driver.manage().window().maximize();
        Thread.sleep(3000);   
        driver.findElement(By.id("txt_account")).sendKeys("ycyzharry");
        driver.findElement(By.id("txt_pwd")).sendKeys("password");
        driver.findElement(By.id("btn_login")).click();
    }

}
复制代码

方法二:先切换到iframe,再进行定位。

复制代码
    @Test
    public void clickButtonTest() throws InterruptedException {

        System.setProperty("webdriver.firefox.bin", "D:\\Program Files\\Mozilla Firefox\\firefox.exe");
        WebDriver driver = new FirefoxDriver();
        driver.get("https://passport.eastmoney.com/pub/login?backurl=http%3A//www.eastmoney.com/");
        driver.manage().window().maximize();
        Thread.sleep(3000);

        WebElement iframe = driver.findElement(By.className("frame_login"));
        driver.switchTo().frame(iframe);
        driver.findElement(By.id("txt_account")).sendKeys("ycyzharry");
        driver.findElement(By.id("txt_pwd")).sendKeys("password");
        driver.findElement(By.id("btn_login")).click();
   }

}

复制代码

值得注意的是,如果iframe有id时,切换iframe时把id作为参数直接传入

driver.switchTo().frame("id");

以上示例中,iframe没有id,只有class="frame_login",所以我们需要先通过classname定位到iframe元素,再把该元素作为参数传入。

例如,如果要跳出iframe,可以使用以下方法:

driver.switchTo().defaultContent();
