Question

我一直在尝试使用网页上的python / selenium自动化报告。现在我正试图选择一个单选按钮。能否帮助我解决这个问题，如果可能的话，可以提供一些使代码看起来/工作得更好的技巧。

我正在使用XPath Helper来识别XPath，但我得到了一个“Null”值：

//*[@id="ctl00_ContentPlaceHolder1_rbUseSpecifiedDeviceConfiguration"]

这是我运行代码时收到的错误消息：

Message: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id='ctl00_ContentPlaceHolder1_rbUseSpecifiedDeviceConfiguration']"}

网页代码

<div class="indent">
                    <div>
                        <input id="ctl00_ContentPlaceHolder1_rbUseDeviceDefaultConfigurations" type="radio" name="ctl00$ContentPlaceHolder1$gnConfigurationType" value="rbUseDeviceDefaultConfigurations" checked="checked"><label for="ctl00_ContentPlaceHolder1_rbUseDeviceDefaultConfigurations">Default Device Configurations</label>
                    </div>
                    <div>

                    </div>
                    <div>
                        <span class="hasValidation"><input id="ctl00_ContentPlaceHolder1_rbUseSpecifiedDeviceConfiguration" type="radio" name="ctl00$ContentPlaceHolder1$gnConfigurationType" value="rbUseSpecifiedDeviceConfiguration" onclick="javascript:setTimeout('__doPostBack(\'ctl00$ContentPlaceHolder1$rbUseSpecifiedDeviceConfiguration\',\'\')', 0)"><label for="ctl00_ContentPlaceHolder1_rbUseSpecifiedDeviceConfiguration">Specify Device Configuration...</label></span>
                    </div>
                    <div class="indent">

                    </div>
                    <div>

                    </div>
                    <div class="indent">

                    </div>
                </div>

在处理单选按钮之前，您应切换到iframe：

driver.switch_to.frame(driver.find_element_by_tag_name('iframe'))
search_box = driver.find_element_xpath("//*[@id='ctl00_ContentPlaceHolder1_rbUseSpecifiedDeviceConfiguration']")        # Specify Device Configuration radioBtn
search_box.click()
