Rendering HTML Strings as HTML with React
In React, you often encounter situations where you need to render HTML strings as actual HTML content. While some attempts may result in the string being displayed as a string rather than HTML, there are several approaches you can adopt to achieve the desired result.
One method is to use the dangerouslySetInnerHTML property when creating an HTML element. This property allows you to insert raw HTML into the component. For example, if you have an HTML string that contains a
element, you can use the following syntax:
<div dangerouslySetInnerHTML={{ __html: "<h1>Hi there!</h1>" }} />
This should render the
element properly in the DOM. However, it's important to note that the string you pass to dangerouslySetInnerHTML must always be sanitized for security reasons.
In your specific case, where this.props.match.description is not rendering as HTML, you can try the following:
- Verify the type: Ensure that this.props.match.description is a string rather than an object. If it's an object, it will likely need to be converted to a string.
- Check for proper markup: If the string is indeed a string, inspect it for any potential markup issues. Ensure that all tags are properly closed and that there are no character entities that may interfere with the rendering.
- Decode HTML entities: If you're dealing with HTML entities, they may need to be decoded before passing them to dangerouslySetInnerHTML. You can use a function like htmlDecode to achieve this.
By implementing these steps, you should be able to successfully render HTML strings as actual HTML in your React application. However, it's always crucial to prioritize security by sanitizing the input before using the dangerouslySetInnerHTML property.

The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
