Why Can\'t My Automation Script Reach Facebook\'s \'FirstName\' Field?

Element Not Reachable by Keyboard

When sending text to the "FirstName" field in Facebook, the error message "Element is not reachable by keyboard" may occur.

Reason

This error can occur due to the以下面因素之一：

• Hidden Element: The element may be visually hidden using CSS or HTML attributes like display: none.
• Overlay: Another element may be blocking the target element, preventing keyboard interaction.
• Incorrect Element Identification: The code may be attempting to interact with an element that does not exist or is not an input field.

Solution

Hidden Element:

Use JavaScript to change the element's display style:

((JavascriptExecutor) driver).executeScript("arguments[0].style.display='block';", element);

Overlay:

Send keys to the target element using JavaScript:

String inputText = "Testing it";
WebElement myElement = driver.findElement(By.id("u_0_b"));
String js = "arguments[0].setAttribute('value','" + inputText + "')";
((JavascriptExecutor) driver).executeScript(js, myElement);

Incorrect Element Identification:

Ensure that the code is selecting the correct input field element. Use dynamic locator strategies to handle changing element identifiers.

Specific to Facebook

In Facebook's case, use xpath locators that target the input field by its name and class:

driver.findElement(By.xpath("//input[@name='firstname' and contains(@class,'inputtext')]")).sendKeys("testing it");

moz:webdriverClick

Firefox provides a capability called moz:webdriverClick to temporarily disable interactive checks. However, this capability will be removed in future releases:

FirefoxOptions options = new FirefoxOptions();
options.setCapability("moz:webdriverClick", false);
