Altering iframe Content with the Help of Selenium Web Driver

I am looking to update the content of an iframe with new material using Selenium WebDriver.

Note: I have attempted the following method:

driver.swithTo().frame(frame_webelement);
driver.findElement(By.xxx).sendKeys("Mycontent");

While I was able to clear the contents of the body within the iframe (using MyWebElement.clear()), I encountered difficulty in sending new content via MywebElement.sendKeys().

Subsequently, I tried a JavaScript solution:

if (driver instanceof JavascriptExecutor) {
        ((JavascriptExecutor) driver).executeScript("document.getElementsByClassName('iframeClass')[0].contentDocument.body.innerHTML='hello_text'");
    }

Upon execution, I received an exception stating "document.getElementsByClassName('iframeClass')[0]" is undefined. Interestingly, the same script worked correctly on FireBug.

Answer №1

//Switch to the iframe
driver.switchTo().frame(frame_webelement);

// then execute the JS code
((JavascriptExecutor) driver).executeScript("document.body.innerHTML='hello_text'");

Your switchTo() method and JavascriptExecutor function both successfully executed. To streamline your process, you can combine both steps into one by not selecting the iframe again in JavaScript since you are already inside it after calling switchTo().
