Question

我正在使用selenium webdriver测试网站。我也导入了所有jar文件，但仍然无法在eclipse中使用Select Class。它给了我一个错误：Select class cannot be instantiated. 我还导入了org.openqa.selenium.support.ui.Select

以下是我的源代码

import org.apache.bcel.generic.Select;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.Select;

public class Dropdown {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        WebDriver driver = new FirefoxDriver();
        driver.get("http://www.makemytrip.com");
          WebElementaddress=driver.findElement(By.xpath(".//[@id='to_typeahead1']"));
        Select sc = new Select (address);  // ERROR LINE
        sc.selectByIndex(5);
    }

}

Answer 1

您可以尝试以下方法。让我们把它分解成几部分。

Select sc = new Select(driver.findElement(By.xpath("your Xpath match case"))); 
                                 **//this will get the dropdown into sc object**
List<WebElement> we = sc.getOptions();  **//to get the options values into list**
System.out.println(we.size());  **//to print the size in console, this and
                                  previous lines for debug/cross checking**
sc.selectByIndex(5);  **//this will select the 5th index and 6th value(indexing starts from 0)**

干杯！

Answer 2

Import org.openqa.selenium.support.ui.Select; package in your project, instead of org.apache.bcel.generic.Select;

错误会消失。

Answer 3

我看到你提供的Xpath不正确。它应该是.//*[@id='to_typeahead1']

此外，此元素不是选择框。它是一个输入框。您可以尝试的是单击元素，然后尝试单击要选择的选项。

Answer 4

我使用了org.openqa.selenium.support.ui.Select包，但效果很好。

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.Select;
import org.testng.annotations.Test;

public class NewClassTest {

    WebDriver driver = new FirefoxDriver();

    @Test
    public void selectOption() {
        driver.get("http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_select");

        WebElement address = driver.findElement(By.tagName("select"));
        Select ab = new Select(address);
    }

}

错误：无法在selenium webdriver中实例化类型Select
