Let's dive in! 🎹\n\nFirst, let's address the error you're seeing: \"Uncaught TypeError: Cannot read properties of null (reading 'addEventListener') at 13:15 in script.js\". This error suggests that there's an attempt to add an event listener to an element that hasn't been properly selected or doesn't exist.\n\nLet's start by adding some basic functionality to handle the MIDI file upload and display a message when a file is selected. We'll also need to ensure that the HTML elements are being correctly accessed in the script.\n\nHere are the steps we'll take:\n\n1. **Ensure the script runs after the DOM has loaded**.\n2. **Add an event listener to handle file uploads**.\n3. **Display a message when a MIDI file is selected**.\n\nLet's start by adding the necessary JavaScript code to handle these tasks.\n\n### Step 1: Ensure the script runs after the DOM has loaded\n\nWe'll wrap our JavaScript code inside a `window.onload` function to ensure it runs after the DOM has loaded.\n\n```javascript\nwindow.onload = function() {\n const midiUpload = document.getElementById('midiUpload');\n \n if (midiUpload) {\n midiUpload.addEventListener('change', handleFileSelect, false);\n } else {\n console.error(\"midiUpload element not found\");\n }\n};\n\nfunction handleFileSelect(event) {\n const file = event.target.files[0];\n if (file) {\n console.log(`Selected file: ${file.name}`);\n } else {\n console.error(\"No file selected\");\n }\n}\n```\n\n### Explanation:\n- **window.onload**: Ensures the code inside runs only after the entire page has loaded.\n- **document.getElementById('midiUpload')**: Selects the file input element.\n- **midiUpload.addEventListener('change', handleFileSelect, false)**: Adds an event listener to handle file uploads.\n- **handleFileSelect**: Function that logs the name of the selected file or an error if no file is selected.\n\nCould you please add this code to your `script.js` file and let me know if it solves the issue? 😃","created_at":"2024-08-29T22:47:09.604609Z","output_tokens":null},{"deleted":0,"code_id":145504,"input_tokens":null,"id":71307,"project_id":3111,"sender":"human","message":"Ok","created_at":"2024-08-29T22:47:33.437412Z","output_tokens":null},{"deleted":0,"code_id":145504,"input_tokens":null,"id":71308,"project_id":3111,"sender":"ai","message":"Awesome! Now that we've ensured the script runs after the DOM has loaded and handles file selection, let's move on to the next steps. \n\n### Next Steps:\n1. **Parse the MIDI file**: We'll need to read and parse the MIDI file to extract its contents.\n2. **Visualize the piano notation**: Once we have the MIDI data, we can visualize it as piano notation.\n\nLet's start with the first step: **parsing the MIDI file**. For this, we can use a JavaScript library called `midi-parser-js` to help us read and parse MIDI files.\n\n### Step 1: Include the MIDI parser library\n\nFirst, we need to include the `midi-parser-js` library in our HTML file. We can add it via a CDN.\n\n```html\n\n \n \n\n```\n\n### Step 2: Parse the MIDI file\n\nNext, we'll update our `handleFileSelect` function to read and parse the MIDI file using `midi-parser-js`.\n\n```javascript\nfunction handleFileSelect(event) {\n const file = event.target.files[0];\n if (file) {\n console.log(`Selected file: ${file.name}`);\n \n const reader = new FileReader();\n reader.onload = function(e) {\n const arrayBuffer = e.target.result;\n const midiData = MidiParser.parse(arrayBuffer);\n console.log(midiData);\n // TODO: Visualize the piano notation\n };\n reader.readAsArrayBuffer(file);\n } else {\n console.error(\"No file selected\");\n }\n}\n```\n\n","created_at":"2024-08-29T22:47:33.444887Z","output_tokens":null},{"deleted":0,"code_id":145506,"input_tokens":null,"id":71309,"project_id":3111,"sender":"human","message":"N","created_at":"2024-08-29T22:47:39.145224Z","output_tokens":null},{"deleted":0,"code_id":145506,"input_tokens":null,"id":71310,"project_id":3111,"sender":"ai","message":"Great, let's proceed with the actual implementation.
