How Do You Handle iFrames in Selenium Webdriver: Switchto()?

iFrames in Selenium are also referred as the inline frame. An inline frame is used to embed any other document within the current/parent HTML document using <iframe></iframe> tags.

Iframes are mainly utilized to insert data from different external sources. For example, if a third party advertisement is displayed on a web page and we need to move that advertisement to a specific position, it can be accomplished using iframe.

Below is the syntax of iframe declared in HTML (DOM)

To handle the iframe in Selenium WebDriver: switchTo():

SwitchTo().frame method primarily enables the browser to switch between multiple frames.  SwitchTo() can be implemented in the following ways:

1. driver.switchTo.frame(int iframe number) - This method allows the web driver to switch to a specific frame using its index, for example- switchTo.frame(2);
2. driver.switchTo.frame(string frameNameOrId) - This method allows the web driver to switch to a particular frame using the defined frame name, for example- switchTo.frame("iframe1");
3. driver.switchTo.frame(WebElement element) - This method allows the web driver to switch to a certain frame based on the location of the web element

Switching to Main Page:

After performing different operations on a particular page, we can switch back to the main page using - switchTo().defaultContent();

We can also use the default method in the ExpectedCondition class to switch on any iframe (if a particular frame is not found then NoSuchFrameException will be thrown):
