无法单击 selenium webdriver 中的特定按钮 [重复]

Question

我无法将商品添加到购物车，因为未选择按钮。

the button in question is the "ADD TO CART" and its only classification is its class called "btn_primary btn_inventory".

this button should add the item selected to the cart as shown:

这是我用来让它选择一个随机按钮并单击它的非工作代码：

WebElement areaInventory = navegador.findElement(By.id("inventory_container"));
        List<WebElement> l1 = areaInventory.findElements(By.className("btn_primary btn_inventory"));
        for(int i=0;i< l1.size();i++){
            Random r = new Random();
            l1.get(r.nextInt(6)).click();
        }

Answer 1

尝试进行下面提到的更改。

更改List<WebElement> l1 = areaInventory.findElements(By.className("btn_primary btn_inventory"));

致List<WebElement> l1 = areaInventory.findElements(By.cssSelector(".btn_primary.btn_inventory"));
