A problem has been solved today. In fact, I think the key point is the analysis of this problem. To be an IT, you must have a technical foundation.

Problem phenomenon, sorry, there is no screenshot, there is a user can correctly log in to a website, most of the links are available, but there is a button can not be used. With the same account, the computers of colleagues abroad are normal.

The general IT solution is to try different browsers, anyway, eight browsers don't work well, and then if you can't solve the problem, you'll want to reinstall the system for users.

For the IT of Class 2, the correct way to solve this problem is actually given a solution through the problem phenomenon of users. The same account, access to the same WEB server, the computer of foreign users is normal, there is a problem in the domestic computer. Remember that the browser accesses the WEB server, gets a bunch of HTML tags that the WEB server spits on him, and then renders it, and then the visible page knows the basics of the WEB S architecture. To solve the problem is to open the development mode of the browser, and then look at the output of elements and Console. If there is no WEB front-end and back-end open foundation, the wool may not be understood.

When I solve this case, I see a lot of JQ errors. The reason is that when the WEB server writes the front end, it refers to the JQ of CDN, but for some reason, the CDN of this JQ is blocked by the domestic network, so it is impossible for the WEB server to transmit the correct content to the browser, and the browser cannot render correctly if it receives incorrect content.

If I go to develop WEB programs, JQ is still downloaded to my own WEB server without quoting CDN. This is a very tangled problem. If JQ is put on its own WEB, it will increase the pressure on its own server. Quote CDN, and if there is something wrong with CDN, it will stop.

To solve the problem, you must understand the principle, otherwise all kinds of reinstallation is a low-level practice. I'm sorry, I've been talking nonsense for a long time, but I don't have a screenshot.
