Question

<button class="button spin-button prod-ProductCTA--primary button--primary" data-automation-id="button" data-tl-id="ProductPrimaryCTA-cta_add_to_cart_button" type="button"><span class="button-wrapper"><span class="spin-button-children">Add to cart</span></span></button>

“进入库存警报”对象

<button class="button spin-button prod-ProductCTA--primary button--primary" data-automation-id="button" data-tl-id="cta_oos_button" aria-expanded="false" aria-label="get in stock alert" role="button" tabindex="0" type="button"><span class="button-wrapper"><span class="spin-button-children">Get in-stock alert</span></span></button>

我不想单击“添加到购物车”。我只想把定位器信息存储在WebElement“AddToCart”中。因为对象具有非常相同的属性，所以我选择了这个唯一的属性“data-tl-id”，但没有起作用。

Web驱动程序

WebElement addToCart = driver.findElement(By.xpath("//button[@data-tl-id='ProductPrimaryCTA-cta_add_to_cart_button']"));

WebElement addToCart  = driver.findElement(By.xpath("//span[@class='button-wrapper']"));

WebElement addToCart = driver.findElement(By.xpath("//span[text()='Add to cart'"));

WebElement addToCart = driver.findElement(By.xpath("//span[contains(@text,'Add to cart')]"));

我得到错误“no such element：Unable to locate element：”。如何定位“添加到购物车”对象？

Answer 1

WebDriverWait wait = new WebDriverWait(driver, 30);
WebElement webElement = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[text()='Add to cart']")));
System.out.println("Printing "+webElement.getText());

WebDriverWait wait = new WebDriverWait(driver, 30);
WebElement webElement = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[contains(text(),'Add to cart')]")));
System.out.println("Printing "+webElement.getText());
