JavaScript Method for Getting an Element by an XPath
The Javascript method document.evaluate() will be used to get an element by an XPath. The document receives an XPath expression as a parameter. Using the evaluate() method, a DOM element that matches the expression is returned.
Using XPath and the document, these procedures can be used to obtain an element.method evaluate():
- Create a fresh JavascriptExecutor object.
- Activate the document.use the evaluate() function of the JavaScript Executor object. As a result, an XPath-compliant DOM element will be returned.
- A WebElement object is created from the DOM element.
Here is an example of how to get an element by XPath using JavaScript in Selenium WebDriver in Java:
Java
// Java program to get an element by XPath // using JavaScript in Selenium WebDriver import org.openqa.selenium.By; import org.openqa.selenium.JavascriptExecutor; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; public class GetElementByXPathUsingJavaScript { public static void main(String[] args) { WebDriver driver = new ChromeDriver(); driver.get("https://www.google.com"); JavascriptExecutor js = (JavascriptExecutor) driver; WebElement element = (WebElement) js.executeScript("document.evaluate('//input[@type=\"text\"]', document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue"); WebElement searchBox = element; searchBox.sendKeys("Selenium WebDriver"); searchBox.submit(); driver.quit(); } } |
Explanation:
- This example will grab the search box element from the Google webpage using the document.evaluate() function. //input[@type=”text”] is the XPath expression used in this example.
- This expression will select the first input element on the page whose type of attribute is set to text.
