需要帮助了解ngRepeat过滤器

Question

I'm trying to figure out what this ng-repeat line of code is doing,

<div ng-repeat="user in filtered = (main.users | candidate: main.filterBy)">

I understand that the line below will simply create a div for all the users in main.users

<div ng-repeat="user in main.users">

What is the first example doing? I assume theres some filter going on but it doesn't resemble the syntax of any filter examples I see in the angular docs

Answer 1

Basically the above syntax does filtering main.users by candidate filter by passing main.filterBy value to that filter by using this line (main.users | candidate: main.filterBy) and the result of this is getting stored in filtered variable. So each time when digest cycle fires up you will see the filtered value updated.

Official refactored and semantic syntax is here

<div ng-repeat="user in main.users | candidate: main.filterBy as filtered">

which clearly says that you can have filtered result in filtered scope variable which is used as alias of that output.
