Master Selenium Locators: name, id, tagName, className, linkText, partialLinkText

By.name()

Demonstrates locating an input element by its name attribute and sending a value using Selenium WebDriver in Java.

public class SearchTextByName {
    public static void main(String[] args) {
        WebDriver driver = new FirefoxDriver();
        driver.get("http://yy3.preview.bicaijia.com/login.do");
        driver.findElement(By.name("code")).clear();
        driver.findElement(By.name("code")).sendKeys("WHBOXEntity002");
    }
}

By.id()

Shows how to locate the same input element using its id attribute and input a new value.

public class SearchTextById {
    public static void main(String[] args) {
        WebDriver driver = new FirefoxDriver();
        driver.get("http://yy3.preview.bicaijia.com/login.do");
        driver.findElement(By.id("code")).clear();
        driver.findElement(By.id("code")).sendKeys("WHBOXEntity002");
    }
}

By.tagName()

Illustrates finding all button elements on the page by their tag name and printing the count.

public class SearchByTagName {
    public static void main(String[] args) {
        WebDriver driver = new FirefoxDriver();
        driver.get("http://yy3.preview.bicaijia.com/login.do");
        List<WebElement> clickButtons = driver.findElements(By.tagName("button"));
        System.out.println(clickButtons.size()); // prints number of buttons
    }
}

By.className()

Uses the element's CSS class name ( form-control) to locate an input field and send text.

public class SearchByClassName {
    public static void main(String[] args) {
        WebDriver driver = new FirefoxDriver();
        driver.get("http://yy3.preview.bicaijia.com/login.do");
        WebElement searchBox = driver.findElement(By.className("form-control"));
        searchBox.sendKeys("Hello,world");
    }
}

By.linkText()

Finds a hyperlink by its exact visible text ("详情") and clicks it.

public class SearchByLinkText {
    public static void main(String[] args) {
        WebDriver driver = new FirefoxDriver();
        driver.get("http://yy3.preview.bicaijia.com/login.do");
        WebElement searchLink = driver.findElement(By.linkText("详情"));
        searchLink.click();
    }
}

By.partialLinkText()

Locates a hyperlink using a partial match of its text (e.g., "详") when the full text is unknown, then clicks it.

public class SearchByPartialLinkText {
    public static void main(String[] args) {
        WebDriver driver = new FirefoxDriver();
        driver.get("http://yy3.preview.bicaijia.com/login.do");
        WebElement searchLink = driver.findElement(By.partialLinkText("详"));
        searchLink.click();
    }
}
