如何找到收音机的输入元素并检查它？总是“无法找到元素”

Question

我正在用 c# 学习 selenium，我正在尝试获取 radio 的输入元素，但总是“无法找到元素”

 <div>
<span id="ctl00_ContentPlaceHolder1_ucObservationSearch1_rblAdvancedSearch" class="radioListOptions">
<input id="ctl00_ContentPlaceHolder1_ucObservationSearch1_rblAdvancedSearch_0" type="radio" checked="checked" value="My" name="ctl00$ContentPlaceHolder1$ucObservationSearch1$rblAdvancedSearch">
<label for="ctl00_ContentPlaceHolder1_ucObservationSearch1_rblAdvancedSearch_0">My</label>
<br>
<input id="ctl00_ContentPlaceHolder1_ucObservationSearch1_rblAdvancedSearch_1" type="radio" onclick="javascript:setTimeout('__doPostBack(\'ctl00$ContentPlaceHolder1$ucObservationSearch1$rblAdvancedSearch$1\',\'\')', 0)" value="Workgroup" name="ctl00$ContentPlaceHolder1$ucObservationSearch1$rblAdvancedSearch">
<label for="ctl00_ContentPlaceHolder1_ucObservationSearch1_rblAdvancedSearch_1">Workgroup</label>
<br>
<input id="ctl00_ContentPlaceHolder1_ucObservationSearch1_rblAdvancedSearch_2" type="radio" onclick="javascript:setTimeout('__doPostBack(\'ctl00$ContentPlaceHolder1$ucObservationSearch1$rblAdvancedSearch$2\',\'\')', 0)" value="Division" name="ctl00$ContentPlaceHolder1$ucObservationSearch1$rblAdvancedSearch">
<label for="ctl00_ContentPlaceHolder1_ucObservationSearch1_rblAdvancedSearch_2">Division</label>
</span>
</div>

我试过了

 ReadOnlyCollection<IWebElement> links1 = driver.FindElements(By.XPath("//input[contains(text(),'Workgroup')]"));
 ReadOnlyCollection<IWebElement> links1 = driver.FindElements(By.XPath("//input[contains(@value,'Workgroup')]"));
 IWebElement check =    driver.FindElement(By.Id("ctl00_ContentPlaceHolder1_ucObservationSearch1_rblAdvancedSearch_1"));

我也尝试在控制台中使用 javascript

document.getElementById("ctl00_ContentPlaceHolder1_ucObservationSearch1_rblAdvancedSearch_1").checked=true

return "TypeError: document.getElementById(...) is null" 我没有更多的解决方案，我需要一些帮助，谢谢

我发现这个html里面多了一个html，也许这就是为什么总是失败，有谁知道怎么处理？

Answer 1

试试这个..

 document.addEventListener("DOMContentLoaded", function (event) {
          document.getElementById("ctl00_ContentPlaceHolder1_ucObservationSearch1_rblAdvancedSearch_1").checked = true;

      });

Answer 2

driver.SwitchTo().Frame("mainContent");
