Java Selenium自定义方法获取Webelement的名称作为参数

如何解决Java Selenium自定义方法获取Webelement的名称作为参数

在我的项目中使用Java Selenium和Page Object，想要创建一个自定义方法，该方法将获取两个字符串作为参数，将它们组合并调用正确的webelement来执行一些操作。

下面是我的Page对象的示例

public class Test extends Base {

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


@FindBy(xpath = "//div[@id='question1No']")
WebElement question1Yes;

@FindBy(xpath = "//div[@id='question1No']")
WebElement question1No;


public Object GetField(String answer,String question) {
    Field field = null;
    try {
        field = Test.class.getField((question+answer).replace("\"",""));
        return field.get(this);
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}

public void answerQuestion(String answer,String question) {    
    WebElement element = (WebElement)GetField(answer,question);
    element.click();

}

并调用该方法，例如：

answerQuestion("Yes","question1")

调用此方法应在question1Yes元素上单击。

解决方法

您可以使用反射。

Field field = Test.class.getField("question1Yes");
WebElement element = (WebElement) field.get(this);

然后您可以使用WebElement进行任何操作

upd。 如果字段是私有的，则写field.setAccessible(true);

添加到以上答案中，根据OP需求以及软件包名称对其进行更新

import java.lang.reflect.Field;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;

public class Test extends base{

    @FindBy(xpath = "//div[@id='question1No']")
    public WebElement question1Yes;

    @FindBy(xpath = "//div[@id='question1No']")
    public WebElement question1No;

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

    public void answerQuestion(String answer,String question) {
        WebElement temp = null;
        try {               
            Field field = Test.class.getField(question + answer);
            temp = (WebElement) field.get(this);
            temp.click();

        } catch (Exception e) {
            // Handle the exception here when there is wrong field
            // throws NoSuchFieldException,SecurityException
            e.printStackTrace();
        }
    }
}

您还可以使用通用方法获取字段

public Object GetField(String answer,String question) {
        Field field = null;
        try {
            field = Test.class.getField(question + answer);
            return field.get(this);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

这样您的代码就会像

import java.lang.reflect.Field;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;

public class Test extends base {

    @FindBy(xpath = "//div[@id='question1No']")
    public WebElement question1Yes;

    @FindBy(xpath = "//div[@id='question1No']")
    public WebElement question1No;

    public Test() {
        PageFactory.initElements(driver,String question) {    
         WebElement temp = (WebElement)GetField(answer,question);
         temp.click();  
    }

    public Object GetField(String answer,String question) {
        Field field = null;
        try {
            field = Test.class.getField(question + answer);
            return field.get(this);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
}
