如何使用Selenium WebDriver C#从下拉列表中选择一个选项?

标签: c# webdriver selenium-webdriver

我正在尝试选择一个选项进行网络测试。可以在此处找到一个示例:http://www.tizag.com/phpT/examples/formex.php

除了选择选项部分外,一切都很有效。如何按值或按标签选择选项?

我的代码:

using OpenQA.Selenium.Firefox;
using OpenQA.Selenium;
using System.Collections.ObjectModel;
using System.Text.RegularExpressions;
using System.Threading;
using System.Diagnostics;
using System.Runtime.InteropServices;

class GoogleSuggest
{
    static void Main()
    {
        IWebDriver driver = new FirefoxDriver();

        //Notice navigation is slightly different than the Java version
        //This is because 'get' is a keyword in C#
        driver.Navigate().GoToUrl("http://www.tizag.com/phpT/examples/formex.php");
        IWebElement query = driver.FindElement(By.Name("Fname"));
        query.SendKeys("John");
        driver.FindElement(By.Name("Lname")).SendKeys("Doe");
        driver.FindElement(By.XPath("//input[@name='gender' and @value='Male']")).Click();
        driver.FindElement(By.XPath("//input[@name='food[]' and @value='Chicken']")).Click();
        driver.FindElement(By.Name("quote")).Clear();
        driver.FindElement(By.Name("quote")).SendKeys("Be Present!");
        driver.FindElement(By.Name("education")).SendKeys(Keys.Down + Keys.Enter); // working but that's not what i was looking for
        // driver.FindElement(By.XPath("//option[@value='HighSchool']")).Click(); not working
        //  driver.FindElement(By.XPath("/html/body/table[2]/tbody/tr/td[2]/table/tbody/tr/td/div[5]/form/select/option[2]")).Click(); not working
        // driver.FindElement(By.XPath("id('examp')/x:form/x:select[1]/x:option[2]")).Click(); not working

        }
}

您必须从下拉列表中创建一个选择元素对象。

 using OpenQA.Selenium.Support.UI;

 // select the drop down list
 var education = driver.FindElement(By.Name("education"));
 //create select element object 
 var selectElement = new SelectElement(education);

 //select by value
 selectElement.SelectByValue("Jr.High"); 
 // select by text
 selectElement.SelectByText("HighSchool");

其他方式可能就是这个:

driver.FindElement(By.XPath(".//*[@id='examp']/form/select[1]/option[3]")).Click();

您可以更改选项[x]中的索引,将x更改为您要选择的元素数。

我不知道这是不是最好的方式,但我希望能帮到你。

为此添加一个点。我遇到了一个问题,即在将Selenium.NET绑定安装到C#项目后,OpenQA.Selenium.Support.UI命名空间不可用。后来发现我们可以通过运行命令轻松安装最新版本的Selenium WebDriver支持类     安装包Selenium.Support 在NuGet包管理器控制台中。

通过文字选择选项;

(new SelectElement(driver.FindElement(By.XPath(""))).SelectByText("");

通过值选择选项:

 (new SelectElement(driver.FindElement(By.XPath(""))).SelectByValue("");

答案 4 :(得分:1)

这是我的工作方式(按ID选择控制和按文字选择):

protected void clickOptionInList(string listControlId, string optionText)
{
     driver.FindElement(By.XPath("//select[@id='"+ listControlId + "']/option[contains(.,'"+ optionText +"')]")).Click();
}

使用:

clickOptionInList("ctl00_ContentPlaceHolder_lbxAllRoles", "Tester");

答案 5 :(得分:1)

您只需传递值并输入密钥:

driver.FindElement(By.Name("education")).SendKeys("Jr.High"+Keys.Enter);

答案 6 :(得分:1)

Selenium WebDriver C#代码,用于从Drop Down中选择项目:

IWebElement EducationDropDownElement = driver.FindElement(By.Name("education"));
SelectElement SelectAnEducation = new SelectElement(EducationDropDownElement);

有三种方法可以选择下拉项目:i)按文本选择ii)按索引选择iii)按值选择

按文字选择:

SelectAnEducation.SelectByText("College");//There are 3 items - Jr.High, HighSchool, College

按索引选择:

SelectAnEducation.SelectByIndex(2);//Index starts from 0. so, 0 = Jr.High 1 = HighSchool 2 = College

按值选择:

SelectAnEducation.SelectByValue("College");//There are 3 values - Jr.High, HighSchool, College

如果您正在寻找下拉框中的任何选项,我也会找到"按索引选择"方法非常有用。

if (IsElementPresent(By.XPath("//select[@id='Q43_0']")))
{
    new SelectElement(driver.FindElement(By.Id("Q43_0")))**.SelectByIndex(1);** // This is selecting first value of the drop-down list
    WaitForAjax();
    Thread.Sleep(3000);
}
else
{
     Console.WriteLine("Your comment here);
}

 var select = new SelectElement(elementX);
 select.MoveToElement(elementX).Build().Perform();

  var click = (
       from sel in select
       let value = "College"
       select value
       );

IWebElement element = _browserInstance.Driver.FindElement(By.XPath("//Select"));
IList<IWebElement> AllDropDownList = element.FindElements(By.XPath("//option"));
int DpListCount = AllDropDownList.Count;
for (int i = 0; i < DpListCount; i++)
{
    if (AllDropDownList[i].Text == "nnnnnnnnnnn")
    {
        AllDropDownList[i].Click();
        _browserInstance.ScreenCapture("nnnnnnnnnnnnnnnnnnnnnn");
    }
}
