Question

我正在尝试访问阴影iframe内的元素。我能够切换到那个框架，但在尝试访问其中的元素时，获得过时的异常。可以对此进行任何帮助。非常感激。提前谢谢..

我使用下面的代码

public void enterCustomerDetails() throws InterruptedException {

        Thread.sleep(2000);
        WebElement root1 = sfdcSelFW.driver.findElement(By.tagName("sb-page-container"));
        WebElement shadowRoot1 = expandRootElement(root1);
        WebElement root2 = shadowRoot1.findElement(By.cssSelector("sb-line-editor"));
        WebElement shadowRoot2 = expandRootElement(root2);
        WebElement root3 = shadowRoot2.findElement(By.cssSelector("sb-le-custom-action-services"));
        System.out.println(root3.getAttribute("id"));
        WebElement shadowRoot3 = expandRootElement(root3);
        WebElement root4 = shadowRoot3.findElement(By.cssSelector("span>sb-popup#popup"));
        WebElement shadowRoot4 = expandRootElement(root4);
        WebElement root5 = shadowRoot4.findElement(By.cssSelector("sb-dialog"));
        WebElement shadowRoot5 = expandRootElement(root5);
        sfdcSelFW.driver.switchTo().frame(shadowRoot5.findElement(By.cssSelector("div>div.sbDialog>div#content>iframe")));
        Thread.sleep(10000);
        WebElement saveBtnEle =  shadowRoot5.findElement(By.cssSelector(" div.slds-grid input"));
        saveBtnEle.click();
}

此处在尝试执行此步骤切换到帧后“WebElement saveBtnEle = shadowRoot5.findElement（By.cssSelector（”div.slds-grid input“））;” 它抛出异常。

即使在切换到帧之后，您指的是shadowRoot5元素以查找帧内的元素。您应该使用sfdcSelFW.driver.findelement代替shadowRoot5.findElement，如下所示。

WebElement saveBtnEle =  sfdcSelFW.driver.findElement(By.cssSelector(" div.slds-grid input"));
saveBtnEle.click();

完整代码，

public void enterCustomerDetails() throws InterruptedException {

        Thread.sleep(2000);
        WebElement root1 = sfdcSelFW.driver.findElement(By.tagName("sb-page-container"));
        WebElement shadowRoot1 = expandRootElement(root1);
        WebElement root2 = shadowRoot1.findElement(By.cssSelector("sb-line-editor"));
        WebElement shadowRoot2 = expandRootElement(root2);
        WebElement root3 = shadowRoot2.findElement(By.cssSelector("sb-le-custom-action-services"));
        System.out.println(root3.getAttribute("id"));
        WebElement shadowRoot3 = expandRootElement(root3);
        WebElement root4 = shadowRoot3.findElement(By.cssSelector("span>sb-popup#popup"));
        WebElement shadowRoot4 = expandRootElement(root4);
        WebElement root5 = shadowRoot4.findElement(By.cssSelector("sb-dialog"));
        WebElement shadowRoot5 = expandRootElement(root5);
        WebElement frame =shadowRoot5.findElement(By.cssSelector("div>div.sbDialog>div#content>iframe")
        WebDriverWait wait = new WebDriverWait(sfdcSelFW.driver,30);
        wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(frame);
        WebElement saveBtnEle =  sfdcSelFW.driver.findElement(By.cssSelector(" div.slds-grid input"));
        saveBtnEle.click();
    }

无法使用selenium java访问阴影框架内的元素
