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

I'm currently learning HTML, CSS, and JavaScipt. I'm trying to make a basic project, but I'm having problems with adding a new image on the new card. When I click on the 'add item' button, I create a new card with image. However, when I add another card for the second time, my image from the first card that I created will disappear. Can someone help me on how to fix this solution. Thank you.

Trying to use Impact font in my html email, which is working fine in Outlook 365 windows and web clients, as well as Gmail client in browser, but the iOS native Mail app, Gmail app and Outlook apps all default back to arial. What am I missing?

Here's the table in question. Class is leftover from a MS port, and I'm leaving it in in the hopes that it improves mso performance, but all it's really doing is setting default font-family, font-size and margin (0).

The highest Y position that is shown in my camera is 5 and -5. For the X its 10. I'm making a tower defense game and I want the tower to follow my mouseposition after I buy it until I click on a place in the track to build/ place it. I got so confused because I couldn't see my tower at all but now I realized that my mouse coordinates are HUGE. It's up to the hundreds on each axis. My screen obviously can't fit that. I tried even dividing the mouseposition in a vector 2 by 45 and making an offset so it can fit well. Unfortunately I have to change the values depending on the screen size so that can't work. I don't know if it matters but here's my script? This script get's called after the tower gets instantiated from the store. The store button is in the canvas if that helps? Maybe the canvas is why everything is off? How do I fix it?

Current example code for check product in shop:

I have a fairly simple shopping app (the Odin Project Shopping Cart project) using react-router-dom. I am keeping the contents of the shopping cart in App component state, but when a new route is rendered, the component state is lost. How do I get the state to persist across route changes?

My App.js looks like this:

I need to count total price of all products, which are added to my shopping cart. Instead it displays total price of all products and the price of one product, which was added, one on another. I can't fix it. I'll add the piece of my code:

I'm a beginner in android development. I've made a single screen app but the content of the app is cutting off in landscape mode. It's a really simple app which shows the details of a shop. The app runs perfectly fine in portrait mode but when I switch it to landscape mode, some of the textviews disappear. I can't figure out what's wrong. Here's the code:
