How to click on the radio button through the element ID attribute using Selenium and C#

问题

I am trying to select a radio button and input element, it has an id of group and value of In_Group. There are 4 different radio buttons with the same id but different values hence I am trying to select the correct one i am looking for.

<input class="custom-radio" id="group" name="group" type="radio" value="In_Group">

I tried something like this:

driver.FindElement(By.XPath("//*[contains(@id='group' and @value='In_Group')]"))

But the element is not found could someone help me out

回答1:

To locate the element you can use either of the following Locator Strategies:

• CssSelector:

  driver.FindElement(By.CssSelector("input#group[value='In_Group']"));
  

• XPath:

  driver.FindElement(By.XPath("//input[@id='group' and @value='In_Group']"));

However, as it is a <input> element and possibly you will interact with it ideally you have to induce WebDriverWait for the desired ElementToBeClickable() and you can use either of the following Locator Strategies:

• CssSelector:

  new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector("input.custom-radio#group[value='In_Group'][name='group']"))).Click();
  

• XPath:

  new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.XPath("//input[@id='group' and @value='In_Group'][@class='custom-radio' and @name='group']"))).Click();
