Page refresh causes pop-up window to disappear: In-depth understanding of the local refresh mechanism

Many developers have encountered such a problem: after the page is refreshed, dynamic elements such as pop-ups will also be refreshed or disappeared, affecting the user experience. This article analyzes the problem of "The pop-up window is refreshed when the page is refreshed, not a request or CSS problem. Even a simple div will be refreshed. How to solve it?"

The questioner has ruled out network requests and CSS style issues, and even if only one div element is used, the problem still exists after refreshing the page. This shows that the problem is not the reload of data or styles, but the overall refresh mechanism of the page.

The root cause is the lack of a local refresh mechanism. Local refresh allows updates to partial content on the page without refreshing the entire page, thus avoiding re-rendering of dynamic elements such as pop-ups. Without partial refresh, the browser can only reload the entire HTML page to display the latest content, causing the pop-up to disappear or reload.

The solution is to introduce a local refresh mechanism, such as using the hot update function that comes with frameworks such as Vue.js and React, or using other front-end construction tools to achieve similar functions. Through partial updates, only the parts that need to be modified are updated to avoid refreshing the entire page, thereby solving the problem of pop-up refresh.
