在iFrame中定位元素时遇到的问题

我试图单击iFrame中的“单选按钮”。我尝试切换iFrame,但遇到了问题。

我试图确定我的元素位于哪个iFrame中,但由于没有此类框架而面临错误。

共享脚本,单击任何单选按钮,导航到我面临问题的页面。

WebDriver driver;
JavascriptExecutor jse;

public static void main(String[] args) 
{

    Sap_Demo demoObj = new Sap_Demo();

    demoObj.invokeBrowser();
    demoObj.initializeSAPFiory();
    demoObj.forecastMD61();

}



public void invokeBrowser()
{
    System.setProperty("webdriver.chrome.driver", "U:\\Research Paper\\Selenium\\Drivers\\Chrome\\chromedriver_win32\\chromedriver.exe");
    driver = new ChromeDriver();

    driver.manage().deleteAllCookies();
    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(40, TimeUnit.SECONDS);
    driver.manage().timeouts().pageLoadTimeout(40, TimeUnit.SECONDS);
}

public void initializeSAPFiory()
{

    try 
    {
        Thread.sleep(1200);
        driver.get("https://dijon.cob.csuchico.edu:8042/erp");
        driver.findElement(By.id("USERNAME_FIELD-inner")).sendKeys("H4");

        driver.findElement(By.xpath("//span[@class='sapMBtnContent sapMLabelBold sapUiSraDisplayBeforeLogin']")).click();
    }

        Thread.sleep(1200);


        /*driver.switchTo().frame(driver.findElement(By.xpath("//span[@id='M0:46:::4:2-imgSymb']")));
        driver.findElement(By.xpath("//span[@id='M0:46:::4:2-imgSymb']")).sendKeys("ABC");*/


        //driver.manage().timeouts().implicitlyWait(40, TimeUnit.SECONDS);
        //Thread.sleep(1600);


        driver.switchTo().frame("ITSFRAME1");
        WebDriverWait wait = new WebDriverWait(driver, 10);
        wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("ITSFRAME1"));

        //WebElement E1 = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("M0:46:::4:2-imgStd")));
        WebElement E1 = driver.findElement(By.xpath("//span[@id='M0:46:::4:2-imgSymb']"));
        E1.click();

        //driver.findElement(By.id("M0:46:::4:2-imgStd")).click();
        //driver.findElement(By.xpath("//span[@id='M0:46:::4:2-imgStd']")).click();
        //Thread.sleep(1200);
    } 
    catch (InterruptedException e) 
    {
        e.printStackTrace();
    }

}

}

接收错误为:

Exception in thread "main" org.openqa.selenium.NoSuchFrameException: no such frame

对于iframe:

<iframe id="ITSFRAME1" name="itsframe1_20190401041759.3908120" noresize="1" frameborder="0" framespacing="0" border="0" scrolling="no" onload="null" style="visibility: visible; z-index: 999; top: 0px; left: 0px;" src="javascript:(function(){document.open();document.domain='dijon.cob.csuchico.edu';self.frameElement.oWguHandlerItsMgrFrame.finalize(); })();"></iframe> 

对于单选按钮:

enter code here <span id="M0:46:::4:2-imgStd" class="lsRBImgStd lsCBImgStdDef lsCBImgStdDefHv"><span id="M0:46:::4:2-imgSymb" class="lsRBImgSymb lsRBImgSel"></span></span>

尝试这些...      driver.SwitchTo().DefaultContent(); IWebElement iframe = driver.FindElement(By.Id("ITSFRAME1")); driver.SwitchTo().Frame(iframe);

Here is my answer from a previous question on this。 (复制/粘贴)它可以在100%的时间内工作(假设页面上有JQuery可用;如果没有,我们可以选择一种替代方法):

因此,这最终是我所做扩展的完美用例。这是其中最重要的部分:

        /// <summary>
        /// Selenium sometimes has trouble finding elements on the page. Give it some help by using JQuery to grab the full qualified xpath to that element.
        /// </summary>
        /// <param name="cssSelector"></param>
        /// <returns></returns>
        public static string GetFullyQualifiedXPathToElement(string cssSelector, bool isFullJQuery = false, bool noWarn = false)
        {

            if (cssSelector.Contains("$(") && !isFullJQuery) {

                isFullJQuery = true;

            }
            string finder_method = @"
                        function getPathTo(element) {
                            if(typeof element == 'undefined') return '';
                            if (element.tagName == 'HTML')
                                return '/HTML[1]';
                            if (element===document.body)
                                return '/HTML[1]/BODY[1]';

                            var ix= 0;
                            var siblings = element.parentNode.childNodes;
                            for (var i= 0; i< siblings.length; i++) {
                                var sibling= siblings[i];
                                if (sibling===element)
                                    return getPathTo(element.parentNode)+'/'+element.tagName+'['+(ix+1)+']';
                                if (sibling.nodeType===1 && sibling.tagName===element.tagName)
                                    ix++;
                            }
                        }
            ";
            if(isFullJQuery) {

                cssSelector = cssSelector.TrimEnd(';');

            }
            string executable = isFullJQuery ? string.Format("{0} return getPathTo({1}[0]);", finder_method, cssSelector) : string.Format("{0} return getPathTo($('{1}')[0]);", finder_method, cssSelector.Replace("'", "\""));
            string xpath = string.Empty;
            try {

                xpath = BaseTest.Driver.ExecuteJavaScript<string>(executable);

            } catch (Exception e) {

                if (!noWarn)  {

                    Check.Warn(string.Format("Exception occurred while building a dynamic Xpath. Css selector supplied to locate element is \"{0}\". Exception [{1}].", cssSelector, e.Message));

                }

            }
            if (!noWarn && string.IsNullOrEmpty(xpath)) {

                Check.Warn(string.Format("Supplied cssSelector did not point to an element. Selector is \"{0}\".", cssSelector));

            }
            return xpath;

        }

通过这种逻辑,您可以通过javascript执行程序将Jquery选择器传递到浏览器中。 jQuery可以毫无问题地查找嵌套在iframe中的元素。尝试这样的事情:

driver.FindElement(By.XPath(GetFullyQualifiedXPathToElement("#MyDeeplyNestedElement")).Click();

可以随意删除该方法/类中与您情况无关的任何内容。

为什么/如何突然使硒可以找到元素??

您可能已经注意到,如果告诉selenium查找iframe html元素,然后在iframe的WebElement中显式搜索,则可以在其下找到子元素。但是,如果没有先找到每个子iframe,Selenium似乎不会在iframe中查找,除非您通过DOM显式地帮助它。

JQuery没有此限制。它会看到每个已注册的DOM元素都很好,并将正常抓取它。将元素作为JQuery对象后,就可以在DOM的整个路径上逐父构建标记的路径。逻辑完成后,您将拥有一个完全合格的XPath,从DOM的顶部一直到嵌套的子元素。然后,一旦将此显式XPath提供给Selenium,您就将其手按住兔子孔穿过一个或多个iframe,直到它碰到您想要的对象。
