Making The Move With ID Locator In Selenium WebDriver

Using ID Locator in Selenium WebDriver

Here I will be sighting an example of TestMu AI login page example for ‘Remember me’ functionality. Below is the screenshot of the same.

Referencing the below DOM structure for ‘Remember me’ element:

<input type="checkbox" name="remember" id="remember" class="form-check-input">

As you can see, the above tag has multiple attributes, one of which is the ID locator.

Syntax For ID Locator In Selenium WebDriver

In order to use the ID Selenium locator to find an element via ID we use the below syntax:

driver.findElement(By.id("remember "));

Now, let’s try to incorporate this into a real-time example. In this example, I will be using the facebook login page, to login using ID locators for interacting with the WebElement object.

Below is the DOM structure for email, password and log in field of the facebook login page:

<input type="email" class="inputtext" name="email" id="email" value="[email protected]" data-testid="royal_email">

<input type="password" class="inputtext" name="pass" id="pass" data-testid="royal_pass">

<input value="Log In" aria-label="Log In" data-testid="royal_login_button" type="submit" id="u_0_8">

Referenced is the screenshot highlighting the same:

Delving Into Code For ID Locator In Selenium WebDriver

The below code will help you relate with the demonstration of ID locator in Selenium WebDriver in a better way. Let’s dig into it:

package Chromedriver;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class Locator_By_ID {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        //Setting up chrome using chromedriver by setting its property
        System.setProperty("webdriver.chrome.driver", "Pth of chrome driver"); 
        
        //Opening browser
        WebDriver driver= new ChromeDriver() ;
        
        //Opening window tab in maximize mode
        driver.manage().window().maximize();
        
        //Opening application
        driver.get("https://www.facebook.com");
        
        //Locating the email field element via ID tag and storing it in the webelement
        WebElement email_field=driver.findElement(By.id("email"));
        
        //Entering text into the email field
        email_field.sendKeys("[email protected]");
        
        //Locating the password field element via ID tag and storing it in the webelement
        WebElement password_field=driver.findElement(By.id("pass"));
                
        //Entering text into the password field
        password_field.sendKeys("xxxxxxxxx");
        
        //Locating the login button to login to the application
        WebElement login_button=driver.findElement(By.id("u_0_2"));
        
        //Clicking on the 'login' button
        login_button.click();
        

    }

}

Another Example For Demonstrating The ID Locator

Let’s cater to another similar example for ID where we are making a booking through Airbnb:

Below is the DOM structure for the same:

Location field:

<input type="text" class="_up0kwni" aria-autocomplete="list" aria-describedby="Koan-magic-carpet-koan-search-bar__description" aria-expanded="false" autocomplete="off" autocorrect="off" spellcheck="false" id="Koan-magic-carpet-koan-search-bar__input" name="query" placeholder="Anywhere" role="combobox" value="Delhi">

Check-in:

<input type="text" class="_14fdu48d" data-veloute="checkin_input" id="checkin_input" name="checkin" placeholder="dd-mm-yyyy" value="Wed, 10th Apr" readonly="" <="" pre="">

<b>Checkout:</b>







<pre> <input type="text" class="_14fdu48d" data-veloute="checkout_input" id="checkout_input" name="checkout" placeholder="dd-mm-yyyy" value="Sun, 14th Apr" readonly="">

Search Button:

<button type="submit" class="_z5x9aua" aria-busy="false"><span class="_ftj2sg4">Search</span></button>

Now let’s dig into the code snippet:

package Chromedriver;

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class ID_Location {

    public static void main(String[] args) throws InterruptedException {
        // TODO Auto-generated method stub


        //Setting up chrome using chromedriver by setting its property
        System.setProperty("webdriver.chrome.driver", "path of chromedriver"); 
        
        //Opening browser
        WebDriver driver= new ChromeDriver() ;
        
        //Opening window tab in maximize mode
        driver.manage().window().maximize();
        
        //Opening application
        driver.get("https://www.airbnb.co.in/");
        
        //Locate element via ID for Location field and store it in Webelement
        WebElement Location= driver.findElement(By.id("Koan-magic-carpet-koan-search-bar__input"));
        
        //Input value in Location field
        Location.sendKeys("Delhi", Keys.ENTER);
        
        //Locate element via ID for Check-in field and store it in Webelement
                WebElement Check_in= driver.findElement(By.id("checkin_input"));
                
                //Click on Check_in field to select the date
                Check_in.click();
                
                //Select the desired date
                driver.findElement(By.xpath("//*[@id='MagicCarpetSearchBar']/div[2]/div/div/div/div[2]/div/div/div/div/div/div[2]/div[2]/div/div[2]/div/table/tbody/tr[2]/td[3]")).click();
                
              //Locate element via ID for Check-out field and store it in Webelement
                WebElement Check_out= driver.findElement(By.id("checkout_input"));
                
                //Click on Check_out field to select the date
                Check_out.click();
                
                //Wait for date selection
                Thread.sleep(3500);
                
                //Select the desired date
                driver.findElement(By.xpath("//*[@id='MagicCarpetSearchBar']/div[2]/div/div/div/div[3]/div/div/div/div/div/div[2]/div[2]/div/div[2]/div/table/tbody/tr[2]/td[4]")).click();
                
                //Locating the submit button and clicking on it
                driver.findElement(By.tagName("button")).click();
                
                //close the driver
                driver.close();
                
        
        
    }
