Can I customize the expiration time of Ajax requests?

Can the expiration time of Ajax requests be customized? In web development, we often use Ajax to implement asynchronous requests to dynamically load data in the page. When making Ajax requests, sometimes we need to control the timeout of the request, that is, set a time limit, and process it if no response is received within the specified time. So, can the expiration time of Ajax requests be customized? This article will introduce this problem in detail and provide specific code examples. Using jQuery's Ajax function

The key to optimizing web page performance: in-depth analysis of the selection of reflow and redraw technologies

The key to improving web page performance: Technical selection analysis of reflow and redrawing With the popularity and development of the Internet, web page performance has become one of the important indicators that users pay attention to. A good web page should load quickly and interact smoothly. To achieve such a goal, the selection of reflow and redrawing technologies is particularly important. Reflow and redraw are two key operations performed by browsers when rendering web pages. Reflow refers to calculating the geometric properties of elements in the document layout, such as position, size, etc. Redrawing, on the other hand, applies the element's style to the content and draws it.

Ways to improve performance of reflow and redraw

How to optimize the performance of reflow and repaint requires specific code examples. Reflow (reflow) and repaint (repaint) are key concepts in web page performance optimization. Reflow refers to the process by which the browser calculates and re-renders the page layout, while redraw is the re-drawing of elements that already exist on the screen. These two processes have an important impact on web page performance, so optimizing the performance of reflow and redrawing is very important. This article will introduce some methods to optimize reflow and redraw, and give specific code examples. Avoid frequently operating style attributes frequently
