HTML5 Data Attributes Not Accessible in React Component Lifecycle Methods
I'm collaborating on a project where I recently switched to I'm relatively new to this, so bear with me. I’m trying to access data attributes in a React component, but I’m running into issues with the lifecycle methods. I have a simple HTML structure that uses data attributes to store some information. Here’s the relevant HTML snippet: ```html <div id="my-element" data-user-id="12345" data-role="admin">User Info</div> ``` In my React component, I’m attempting to read these data attributes in the `componentDidMount` method like this: ```javascript import React from 'react'; class UserInfo extends React.Component { componentDidMount() { const userElement = document.getElementById('my-element'); const userId = userElement.getAttribute('data-user-id'); const userRole = userElement.getAttribute('data-role'); console.log(userId, userRole); } render() { return <div id="my-element" data-user-id="12345" data-role="admin">User Info</div>; } } export default UserInfo; ``` However, I am encountering the issue where the console logs `null` for both `userId` and `userRole` when the component mounts. I’ve checked that the element exists in the DOM, and I can see it in the inspector. I’ve also tried accessing the data attributes in `componentWillMount` and `render`, but I still get `null`. It looks like the data attributes are not being read correctly. I’ve verified that I’m using React version 17.0.2. Is there something I’m missing here? Shouldn’t the lifecycle method be able to access the attributes once the component is mounted? Any insights on how to properly extract data attributes in React would be appreciated, especially if there are any best practices I should follow. For context: I'm using Javascript on Windows. Is there a better approach? My team is using Javascript for this REST API. I'd love to hear your thoughts on this. Cheers for any assistance!
