如何选择Selenium WebDriver中的单选按钮？

我是Selenium Webdriver的新手。我正在使用Java编写脚本，但是我被困在编写脚本中，我想选择一个单选按钮，但是

线程“主要” org.openqa.selenium.ElementNotVisibleException中的异常：未显示元素（警告：服务器未提供任何堆栈跟踪信息）错误。

这是我写的：

WebElement radioButton = driver.findElement(By.id("Radio_0_2461A"));
radioButton.sendKeys(Keys.SPACE);

以下是HTML代码：

HTML code for Find button.

<button class="button right secondary" id="selectProducts0" onclick="getProducts('0'); return false;">
        Find Products
    </button>

单击按钮后，将加载产品，我必须从列表中选择产品。

    <div class="clearboth" id="productList0" style="overflow: hidden; display: block;">
    <div class="productTableContainer" data-index="0">

 <table class="responsive" cellspacing="0" cellpadding="0" summary="List of products">
   <tbody>            
    <tr data-row-data='{"earlyRepaymentCharges":[],"incentives":[]}'>
    <th class="radio">
    <input id="0_2689A_StartDate" type="hidden" value="28/06/2016 00:00:01">
    <input name="Products[0].ProductCode" title="Lifetime Tracker with £999 Fee" id="Radio_0_2689A" type="radio" value="2689A"> <label for="Radio_0_2689A">
     Lifetime Tracker with £999 Fee </label>

<tr data-row-data='{"earlyRepaymentCharges":[{"step":"1","durationInMonths":"","endDate":"30/11/2016","percentage":"1%"}],"incentives":[]}'>
    <th class="radio">
   <input id="0_5555A_StartDate" type="hidden" value="01/11/2015 00:01:00">
   <input name="Products[0].ProductCode" title="1 Year Fixed Rate Until 30/11/2016 with £999 Fee" id="Radio_0_5555A" type="radio" value="5555A">
 <label for="Radio_0_5555A"> 1 Year Fixed Rate Until 30/11/2016 with £999 Fee
 </label>

<tr data-row-data='{"earlyRepaymentCharges":[{"step":"1","durationInMonths":"","endDate":"28/02/2017","percentage":"2%"},{"step":"2","durationInMonths":"","endDate":"28/02/2018","percentage":"1%"}],"incentives":[]}'>
 <th class="radio">
<input id="0_2461A_StartDate" type="hidden" value="18/12/2015 00:01:00">                          
<input name="Products[0].ProductCode" title="2 Year Fixed Rate Until 28/02/2018 with £999 Fee" id="Radio_0_2461A" type="radio" value="2461A">
 <label for="Radio_0_2461A">2 Year Fixed Rate Until 28/02/2018 with £999 Fee
</label>

我认为单选按钮是动态生成的。尝试By.name()与withWebDriverWait一起使用，直到单选按钮如下所示：-

WebDriverWait wait = new WebDriverWait(driver,10);
WebElement radio = wait.until(ExpectedConditions.visibilityOfElementLocated(By.name("Products[0].ProductCode")));
radio.click();

Edited1：-如果单选按钮ID是固定的，则尝试使用By.idwithWebDriverWait直到单选按钮可见，如下所示：-

WebDriverWait wait = new WebDriverWait(driver,10);
WebElement radio = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("Radio_0_2461A")));
radio.click();

Edited2：-如果您可以找到单选按钮，但由于可见性而无法选择，则可以尝试使用JavascriptExecutor来选择单选按钮，如下所示：-

WebDriverWait wait = new WebDriverWait(driver,10);
WebElement radio = wait.until(ExpectedConditions.presenceOfElementLocated(By.id("Radio_0_2461A")));
((JavascriptExecutor)driver).executeScript("arguments[0].click()", radio);

Edited3：-如果不幸的是，javascript单击在单选按钮上不起作用，请尝试使用Javascript Mouse事件执行单击，如下所示：-

WebDriverWait wait = new WebDriverWait(driver,10);
WebElement radio = wait.until(ExpectedConditions.presenceOfElementLocated(By.id("Radio_0_2461A")));
((JavascriptExecutor)driver).executeScript("var clickEvent = document.createEvent('MouseEvents');clickEvent.initEvent ('click', true, true);arguments[0].dispatchEvent (clickEvent);", radio);

希望能帮助到你...：）
