I wrote this chunk of code

driver = webdriver.Chrome()
        siteURL = ("https://food.google.com/chooseprovider?restaurantId=/g/1tcxf3dw&hl=en- 
        US&gl=us&cs=1&ssta=1&fo_m=MfohQo559jFvMWwP9igWZeWQMczq7voErUdXMT_RFPQ05bfKMQVr5-7IofUJMU_hT8vrWuwRMUOzJVpjPL1YMfaXTPp5KXh-OAE=&gei=RPlNYdqNL-PB_Qb224zgCA&fo_s=OA,AH&orderType=2&sei=CXOeg4KHbv-eEWRLD3Wg9SOp&utm_campaign&utm_source=search")
driver.get(siteURL)
addFood = driver.find_element_by_id('-3088730200806839963')
addFood.click()

which I used to check to see if I can successfully find elements using their ids. It worked fine so then I decided to make it more efficient and created a json file which is this

{ 
    "food_apps": [
        {
            "Fried Calamari": "-3088730200806839963"
        },
        {
            "Our Famous Wings": "-1350800096379223241"
        },
        {
            "4 Piece Garlic Rolls": "-8109616989190485452"
        },
        {
            "5 Piece Mozzarella Sticks": "-3728727160150417226"
        },
        {
            "4 Piece Garlic Rolls With Sauce": "-1575357319596201105"
        },
        {
            "Eggplant": "-141455748912371356"
        },
        {
            "French Fries": "-5396459955060315412"
        },
        {
            "Broccoli Rabe": "3194878292893763893"
        },
        {
            "Onion Rings": "8601302989180579560"
        },
        {
            "Chicken Fingers With Fries": "-4477197721082407141"
        },
        {
            "Clams": "1350099334219961828"
        },
        {
            "Mussels": "-3470276416589467842"
        },
        {
            "Shrimp Basket": "-6884592797623295987"
        },
        {
            "Meatballs": "5243069348564888695"
        },
        {
            "Sausages": "1861088016475321205"
        },
        {
            "Eggplant Layers": "7657135224437837293"
        }
    ]
}

which I get a user input and match it to its respected ID value in the file with this code here

        n = 1

        for i in appOptions:
        
            print("#",n, ":", appOptions[n-1])
            n = n   1

        optionFood = int(input("What do you want to order? (enter the option #)"))
        time.sleep(2)
        optionFood = optionFood - 1
        appChoice = appOptions[optionFood]
        print("Do you want to add ", appChoice , "to your order?")
        y = input("(Enter 'y or n' to continue: )").lower()

        if y == "y" or "yes":
            f = open('food.json',)
            data = json.load(f)
        
            item = str(data['food_apps'][optionFood])
            itemID = item.split(':')[1].lstrip().split(' ')[0].lstrip('"').rstrip('"}')

after printing itemID, say I chose fried calamari I get as an output '-3088730200806839963' Which is what I want, but as soon as I try to swap the hard coded value in find_element_by_id() and make the statement

addFood = driver.find_element_by_id(itemID)

I get this error

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[id="'-3088730200806839963'"]"}

For help here is the code all together:

choiceOrder = input("Do you want to pick up your order or have it delivered? \n").lower()
time.sleep(2)
if (choiceOrder == "pick up" or "pickup" or "pick-up"):
    startFood = input('Do you want Appetizers, Salads, Pasta, Pizza, Entrees, or Hot & Cold Subs?').lower()
    if startFood == ("apps" or "appetizers"):
        appOptions = [
            "Fried Calamari",
            "Our Famous Wings",

            n = n   1

        optionFood = int(input("What do you want to order? (enter the option #)"))
        time.sleep(2)
        optionFood = optionFood - 1
        appChoice = appOptions[optionFood]
        print("Do you want to add ", appChoice , "to your order?")
        y = input("(Enter 'y or n' to continue: )").lower()

        if y == "y" or "yes":
            f = open('food.json',)
            data = json.load(f)
        
            item = str(data['food_apps'][optionFood])
            itemID = item.split(':')[1].lstrip().split(' ')[0].lstrip('"').rstrip('"}')
            print(str(itemID), "\n\n\n\n\n\n\n\n\n\n\n\n\n\n")
            time.sleep(2)
            addFood = driver.find_element_by_id(itemID)
            addFood.click()

NOTE: I purposely didnt include options=options into the params so I can correctly debug what is happening.

CodePudding user response：

I can see issue with these two lines of code, and in error also you can witness the same.

item = str(data['food_apps'][optionFood])
            itemID = item.split(':')[1].lstrip().split(' ')[0].lstrip('"').rstrip('"}')

In the error you can easily see extra quote as you are type casting item to string. "[id="'-3088730200806839963'"] The possible solution will be use the item object as is as it would be a touple and you can do indexing there too. Below solution should work

itemID = data['food_apps'][optionFood][1]
             

CodePudding user response：

The IDs might get changed during run-time. Try catching the element you want with the following code:

element = driver.find_element_by_link_text("Fried Calamari")
element.click()
