In angular, there is jqlite.
If jquery is introduced in the project, jqlite will be pointed to jqurey, otherwise a simple jquery encapsulated by itself will be used.
But no matter which one it is, the available APIs are limited and not as many as jquery.
Especially in the angular instructions, so I am very confused, how can the two work together to fully utilize their respective advantages?
Unless some libraries depend on jQuery, don’t introduce jq. If it can be written in ng, don’t use jq...
ng's built-in DOM operation is sufficient. Moreover, ng applications should not manually operate the DOM except for directives. If you want to use jq, it is in the directive.
Angular Js has its own one called jqlite, which is roughly similar to jQuery in usage, but not as complete;
If you reference the complete jQuery library in the header, you don’t need to consider jqlite.
