The development of WEB is mainly based on two interactions (Bhand S data).

Browser:

1 contains client code running errors such as html, css, js, etc.

Transmission side:

1 error in path introduction, introduction of common plug-ins (artDialog, Ztree, JQuery, etc.), image path, video path, etc.

2 files (js, css, pictures, videos, etc.) are too large, resulting in slow browser parsing and long loading time, so these files can be compressed properly.

Server:

1 dynamic web page-data source (that is, data manipulation program) error.

2 data errors in the database or file.

Schematic:

Common ways for clients to handle errors (common tool F12):

1, html, css debugging direct arrow (you can view the attributes of the element), js debugging, generally set breakpoints.

2. Cache accumulation causes errors and cleans up the cache.

3. By passing values on pages and processing requests, requests and responses between pages in the network can be captured.

4. Cookie, Session processing, cleaning.

Note:

[browser engine rendering method (take IE as an example):

1. Browser browsing mode, that is, the browser default engine type {IE7 6 version is IE7 6 engine}

two。 Document browsing mode, that is, the actual parsing mode of the code

{can be set by manual code: no matter what version of IE, the IE7 engine has parsed the html code}
