如何检查Selenium中是否存在webelement？

Question

I want to create a java method which can check if an actual selenium webelement exists. 我想创建一个Java方法，可以检查是否存在实际的硒Webelement。

It's important, that I need to create a method, which would get a Webelement as a parameter, not a By or String id. 重要的是，我需要创建一个方法，该方法将获取Webelement作为参数，而不是By或String id。 And I want to avoid try-catch solution, which would return a false if a NoSuchElementException would occure. 而且我想避免尝试捕获解决方案，如果发生NoSuchElementException，该解决方案将返回false。

public boolean isElementExists(WebElement element) {
    //TODO Implement...
}

Example: 例：

foo.html foo.html

<!DOCTYPE html>
<html>
<body>

<button id="button1" type="button">First button</button>

</body>
</html>

FooPage.java FooPage.java

public class FooPage {

    @FindBy(how = How.ID, using = "button1")
    public WebElement fistButton;

    //Missing button
    @FindBy(how = How.ID, using = "button2")
    public WebElement secondButton;

}

FooPageTest.java FooPageTest.java

public class FooPageTest {
    public void test(FooPage page) {
        page.firstButton.click(); // OK
        page.secondButton.click(); // NoSuchElementException
        //So I need to check if element exists in this class.
        //I can access here to the FooPage, the webelement to check, and to the driver.
    }
}

Since Selenium throws a NoSuchElementException when attempting to click on the second button, create a method in your page object that does the clicking: 由于Selenium在尝试单击第二个按钮时会引发NoSuchElementException，因此请在页面对象中创建一个方法来执行单击：

public class FooPage {
    @FindBy(how = How.ID, using = "button1")
    public WebElement firstButton;

    //Missing button
    @FindBy(how = How.ID, using = "button2")
    public WebElement secondButton;

    public FooPage(WebDriver driver) {
        PageFactory.initElements(driver, this);
    }

    public void clickThebuttons() {
        firstButton.click();

        try {
            secondButton.click();
        } catch (NoSuchElementException ex) {
            // Do something when the second button does not exist
        }
    }
}
