Question

尽管x路径选择了元素，并且我尝试使用java执行器，但在代码运行时，它只能单击购物车中第一个元素的更新按钮。下面是代码:

在将 3 个产品放入购物车后，我将文本框添加到列表中:

List<WebElement> li2 =driver.findElements(By.xpath(".//td[@class='product- 
cart-actions']/input"));


for(int j=0;j<li2.size();j++)
    {

        if(j==0)
        {
            li2.get(j).clear();
        li2.get(j).sendKeys("4");
        driver.findElement(By.xpath(".//td[@class='product-cart-actions']/button[@title='Update']")).click();
        li2 =driver.findElements(By.xpath(".//td[@class='product-cart-actions']/input"));
        }
        else if(j==1)
        {
            li2.get(j).clear();
            li2.get(j).sendKeys("2");
            //wait.until(ExpectedConditions.elementToBeClickable(By.xpath(".//td[@class='product-cart-actions']/button[@title='Update' and @type='submit']")));
            //driver.findElement(By.xpath(".//td[@class='product-cart-actions']/button[@title='Update' and @type='submit']")).isDisplayed();

            WebElement element = driver.findElement(By.xpath(".//td[@class='product-cart-actions']/button[@title='Update' and @type='submit']"));
            try {
                if (element.isEnabled() && element.isDisplayed()) {
                    System.out.println("Clicking on element with using java script click");

                    ((JavascriptExecutor) driver).executeScript("arguments[0].click();", element);
                } else {
                    System.out.println("Unable to click on element");
                }
            } catch (StaleElementReferenceException e) {
                System.out.println("Element is not attached to the page document "+ e.getStackTrace());
            } catch (NoSuchElementException e) {
                System.out.println("Element was not found in DOM "+ e.getStackTrace());
            } catch (Exception e) {
                System.out.println("Unable to click on element "+ e.getStackTrace());
            }
        //  if (element.isDisplayed()) {
            //  element.click();
            //}


            li2 =driver.findElements(By.xpath(".//td[@class='product-cart-actions']/input"));
        }


        else
        {
            li2.get(j).clear();
            li2.get(j).sendKeys("3");

            WebElement element1 = driver.findElement(By.xpath(".//td[@class='product-cart-actions']/button[@title='Update']"));

        if (element1.isDisplayed()) {
             element1.click();
            }       
        }

Answer 1

这就是罪魁祸首:-

WebElement element = driver.findElement(By.xpath(".//td[@class='product-cart-actions']/button[@title='Update' and @type='submit']"));

因此，当您有多个具有相同定位器的元素时，WebDriver 单击第一个元素并继续前进。因此，如果您想单击 2nd 或 3rd 元素，您可以修改您的 xpath，例如:-

.//td[@class='product-cart-actions']/button[@title='Update' and @type='submit'][2]   -- For 2nd Element

或者

.//td[@class='product-cart-actions']/button[@title='Update' and @type='submit'][3]  -- For 3rd element.

但这不是一个好的方法，将来可能会有多个元素，并且您不会为每个元素添加索引。

最好的方法是引用产品名称(在您的情况下唯一)来识别更新按钮。
