How can i send keys to an iframe when iframe is the only element in the iframe

Question

I have this iframe which is for inputting the card number.

I am trying this in chrome headless mode

<iframe hspace="0" vspace="0" frameborder="0" scrolling="no" allowtransparency="true" marginwidth="0" marginheight="0" 

Answer 1

Write the Xpath for that iframe like the below. As you mentioned

I have this iframe which is for inputting the card number.

so there is an attribute for for card number.

//iframe[@attribute='value']

Eg:

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

WebElement ele = driver.findElement(By.xpath("//iframe[@attribute='value']"));

ele.sendKeys('Text');

or

driver.switchTo().frame(driver.findElement(By.xpath("//iframe[@attribute='value']")));

WebElement inputtext = driver.findElement(By.xpath("//input[@attribute='value']"));

inputtext.sendKeys("text");

Hope this answer your question, please share the HTML from inspect element if this does not answer your question.
