Let's talk about jQuery and Google request issues in 360 browser

In front-end development, the jQuery library has become one of the essential components. It encapsulates a series of practical methods and properties, making JavaScript programming more convenient and readable. However, some developers will encounter a strange problem when using the jQuery library, that is, 360 Browser will request Google's servers.

Here, the first thing we need to understand is that 360 Browser will request Google's server and download some JavaScript files under certain circumstances. These requests are usually triggered by the use of some Google services or resources in the page. Among them, the more common situation is that the Google Fonts font library or the Google Analytics website analysis service is used in the page.

Due to some historical reasons, 360 Browser will handle HTTP requests in a special way when processing these requests. Specifically, when 360 Browser finds that there is a request to Google's server in the page, it will first search locally to see if there is already a cache. If the cache is found, the resource will be fetched directly from the cache without making a real HTTP request to Google's servers. If there is no cache or the cache has expired, a request will be made to the Google server.

When using the jQuery library in a page, we usually reference it through a script tag. In fact, this script tag is an HTTP request, which requests the resource file of the jQuery library. If 360 Browser does not cache the jQuery library at this time, it will initiate a request to the server and download the file. However, while downloading the jQuery file, 360 Browser will also check whether there are Google-related requests in the page. If it exists, 360 Browser will obtain the resource directly from the cache without making a new request to the Google server. This has led to some problems. If Google's resources, such as fonts, APIs, etc., are used in the jQuery library, these resources cannot be obtained, affecting the normal functions and display effects of the page.

To avoid this problem, we can avoid using Google resources in the jQuery library in some ways. One way is to use the jQuery library on a CDN, which not only avoids issues with Google resources, but also improves page loading speed and performance. Another way is to handle all Google requests individually instead of using 360 Browser's caching mechanism. The specific method is to add a hidden iframe to the page and place all Google-related requests in this iframe. This can avoid the caching mechanism of the 360 ​​browser and ensure that all resources can be loaded normally.

In short, when using the jQuery library, if we encounter the problem of 360 browser requesting Google, we need to pay attention to whether Google resources are used in the page and take corresponding measures to solve this problem.
