如何使用C＃在Selenium WebDriver中单击列表中的项目？

Question

Hi I need to verify if the item I'm going to click has a dollar sign and is not out of stock. So I have used this method.This works fine if the first item on the list satisfies both the condition but in case if the first item doesn't have a dollar sign it does not go to the second item and click it, instead it fails. As I'm new to programming I don't know if I have made any mistake in the code. How can I correct this ? Thanks.

Code:

        ReadOnlyCollection<IWebElement> listOfItems = driver.FindElements(By.CssSelector("ul[class='shelf-list tap-list search']>li"));
            foreach (IWebElement item in listOfItems)
            {
                //To check if item is not sold out get the class attribute of item and check if empty
                string className = item.GetAttribute("class");
                Console.WriteLine("Classname:" + " " + className);
                if (className.Equals(""))
                {
                    //Item is available and now get text and check if it has $ sign
                    IWebElement itemWithDollarSign = driver.FindElement(By.CssSelector("div[class='item-preview-text']>div[class='price']"));
                    string ItemToChoose = itemWithDollarSign.Text;
                    Console.WriteLine("Text:" + " " + ItemToChoose);
                    if (ItemToChoose.Contains("$"))
                    {
                        //Choose the item that satifies both conditions
                        itemWithDollarSign.Click();
                        break;
                    }
                }
            }

Case 1 output: if item satisfies both condition

Classname:
text: $189

// shows classname is empty and it entered the loop.

case 2 output: if first item doesnot have $

Classname:
text: Prices varies
Classname:
text: Prices varies
Classname:
text: Prices varies...

keeps repeating the same for 30 items on page instead of going to second one.

Answer 1

The inner FindElement appears to want to get itemWithDollarSign related to the looping item , but it appears to actually be static.

This library isn't my bread and butter, but could this be it:

IWebElement itemWithDollarSign = item.FindElement(By.CssSelector("div[class='item-preview-text']>div[class='price']"));
