如何更新页面上的 Webelements 列表？

Question

如题——如何正确刷新“productList”，最终在目录中找到具体的产品？

即使产品本身在页面上可见，此方法也会一直点击“显示下一个产品”按钮。这意味着“productList”尚未刷新。

   public void findProductAndAddToCart()  {

        //searching for products by className
        List<WebElement> productList = SeleniumDriver.getDriver().findElements(By.className("bcom--txtBold"));

    for (int i = 0; i < productList.size(); i++) {
        //getting the numbers of the products
        String element = productList.get(i).getText();

        if (element.equals("7000029644")) {
            productList.get(i).isDisplayed();
            System.out.println("Product is displayed");
            SeleniumDriver.getDriver().findElement(By.xpath("XPATH - Add to Cart Button')]")).click();
            break;

        } else {

            //the product hasn't been found, so need to click "Show Next Products"
            SeleniumDriver.getDriver().findElement(By.xpath("//a[contains(.,'Show Next')]")).click();
            List<WebElement> newProductList = SeleniumDriver.getDriver().findElements(By.className("bcom--txtBold"));
            productList.addAll(newProductList);


        }

你可以试试这样的

public void findProductAndAddToCart() {

    boolean flag = true;

    while (flag) {
      flag = isNextEnabled();

      //searching for products by className
      List<WebElement> productList = SeleniumDriver.getDriver()
          .findElements(By.className("bcom--txtBold"));

      for (WebElement e : productList) {

        //getting the numbers of the products
        String element = e.getText();

        if (element.equals("7000029644")) {
          e.isDisplayed();
          System.out.println("Product is displayed");
          SeleniumDriver.getDriver().findElement(By.xpath("XPATH1')]")).click();
          flag = false;
          break;

        } else {
          //don't click next here
          }
      }
          SeleniumDriver.getDriver().findElement(By.xpath("//a[contains(.,'Show 
   Next')]")).click();
    }
  }

  private boolean isNextEnabled() {
    return SeleniumDriver.getDriver()
        .findElements(By.xpath("//a[contains(.,'Show Next')]")).isEnabled;
  }
