java - 使用 WebDriver 无法在表元素中找到要单击的特定 td

Question

这就是我想要达到的元素

<table border="0" cellpadding="0" cellspacing="0" width="930"><tbody>
 <tr>
   <td height="32"><span style="cursor: pointer; text-decoration:underline; font-size:14px;" onClick="commentsDisplay(9427356)"><b>Display / write / close (0) comment(s) for this video.</b></span> </td>
 </tr> </tbody></table>

它没有 id，没有名称，什么都没有...并且该网页中有多个表格元素...我怎样才能让它变得不同并让 WebDriver 点击它？我尝试使用 partialLinkText，但它不起作用(有点预期，因为它不是属性标签)

这是我的 java 类

 // Find the text input element by its name

        WebElement element = driver.findElement(By.id("q"));

        // Enter something to search for

        element.sendKeys(searchQ[rnd.nextInt(4)]);

        // Now submit the form. WebDriver will find the form for us from the element

        element.submit();

        //Open random Video

        driver.findElement(By.className("miniature")).click();

        //Open Comments box

        By xpath = By.xpath("//span[contains(@onClick,'commentsDisplay')]/b");
        WebElement myDynamicElement = (new WebDriverWait(driver, 10)).until(ExpectedConditions.presenceOfElementLocated(xpath));
        myDynamicElement.click();

        // Check the title of the page

        System.out.println("Page title is: " + driver.getTitle());

        driver.quit();

Answer 1

尝试以下xpath

//span[contains(@onClick,'commentsDisplay')]/b

或css

span[onClick^='commentsDisplay']>b

如果该元素需要一些时间来加载，则使用显式等待:

By xpath = By.xpath("//span[contains(@onClick,'commentsDisplay')]/b");
WebElement myDynamicElement = (new WebDriverWait(driver, 10)).until(ExpectedConditions.presenceOfElementLocated(xpath));
myDynamicElement.click();
