QUESTION
I am trying to create a shopping cart in JavaScript. When I click on the button, the price of item should increase according to the number of times I have clicked on the button. I've tried the below code but it's not working. The problem is that after clicking few times the multiplication goes like this:
suppose initial price =49
49 x 1
49 x 2
94 x 3
282 x 4 (it should be 49 x 4);
I have modified the code,it works fine in console.log() but gives different result if I assign the variable newPrice to document.getElementById().innerHTML
ANSWER
Answered 2021-Jun-15 at 12:34I think this
const newprice = document.getElementById("discount").innerHTML *=counter;
should be
const newprice = document.getElementById("discount").innerHTML +=counter;
note the + and not the * before the =counter. the plus is adding the star is multiplying.
QUESTION

Heyy ^^ I'm coding a selenium program, but I'm stuck in one place. This program is made to buy 1 graphics card, on a French site, for my son's birthday. So there you have it, I coded everything but now my concern is that the web page of this graphics card is only available when it is in stock so the program cannot find the button by xpath "add to cart" . So I had the idea to make a loop so that as long as the "add to cart" button is not available, the program opens the page of the graphics card to infinity (like this when it is available, the button appears and the rest is done). However, I don't know how to achieve this condition, this loop, can you help me? I am on selenium with webdriver

The task is to build an accurate price calculator which accounts for a sales price based on quantity. I've built a gross price calculator using compiledCart.reduce() method, (below) however I can't figure out how to add the sales functionality.
If the user buys 1 Candy, the price is $3.97, if the user buys 2, the price is $5.00. If the user buys 3, then first two are $5.00 and the 3rd is $3.97. Same thing if the user buys 5. The first 4 are $10 and the 5th one is $3.97

QUESTION
I am building an order form that limits how many items you can order based on the stock of the item. I have a menu collection which has items
ANSWER
Answered 2021-Jun-10 at 20:49You should deffinitely use a cloud function to update the stock. Create a function onCreate and onDelete functions trigger. If users can change data you would also need to onWrite function trigger.
Depending on the amount of data you have you woould need to create a custom queue system to update the stock. Belive me! It took me almost 2 years to figure out to solve this. I have even spoken with the Firebase engeeners at the last Firebase Summit in Madrid.
Usualy you would use a transaction to update the state. I would recommend you to do so if you don't have to much data to store.
In my case the amount of data was so large that those transactions would randomly fail so the stock wasn't correct at all. You can see my StackOverflow answer here. The first time I tought I had an answer. You know it took me years to solve this because I asked the same question on a Firebase Summit in Amsterdam. I asked one of the Engeeners who worked on the Realtime Database before they went to Google.
There is a solution to store the stock in chunks but even that would cause random errors with our data. Each time we improved our solution the random errors reduced but still remained.
The solution we are still using is to have a custom queue and work each change one by one. The downside of this is that it takes some time to calculate a lot of data changes but it is 100% acurate.
Just in case we still have a "recalculator" who recalculates one day again and checks if everything worked as it should.
Sorry for the long aswer. For me it looks like you are building a similar system like we have. If you plan to create a warehouse management system like we did I would rather point you to the right direction.
In the end it depends on the amount of data you have and how often or fast you change it.

Install Cart
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
