JavaSelenium自定义方法获取webelement的名称作为参数

Question

在我的项目中使用JavaSelenium和Page Object，想要创建一个自定义方法，将两个字符串作为参数，组合它们并调用右webelement来执行一些操作。

下面的例子我的页面对象

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();

}

例如，调用该方法：

answerQuestion("Yes", "question1")

调用此方法应执行click on question1Yes元素。

添加到上面的答案更新它根据操作需要以及包名称

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();
        }
    }
}

还可以使用常用方法获取字段

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;
        }
    }

这样你的代码就会

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 = (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;
        }
    }
}

Answer 2

你可以使用反射。

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

然后你可以用你的网页元素做任何你想做的事

upd。如果字段是私有的，则写入字段。setAccessible（真）
