javascript - How can you filter objects by an array in angularjs -

was wondering if can filter existing array array of filter.

so our original json was:

[     {     "bookname": "harryporter",     "year": "2000",     "author":"j. k. rowling"     },      {     "bookname": "sleepless",     "year": "2003",     "author":"connie ann michael"     },     {     "bookname": "no man's land",     "year": "1993"     "author":"harold pinter"     }  ]; 

filter array:

[ "year":"1993" "bookname":"no man" ] 

also there way dynamically add elements array when edit input, perhaps type in text ?

for example:

input

<div> <input type="text" ng-model={{ filterarray.insert("bookname":"value") }}>book name </div> 

filter

<div ng-repeat="books in originaljson | filter: filterarray"> {{books.author}} </div> 

i hope have explained question enough, cheers

if want filter multiple values, can pass in filter-object.
each key corresponds field-name , each value filters items based on corresponding key.

book name: <input type="search" ng-model="filterobj.bookname" /> year:      <input type="search" ng-model="filterobj.year" /> <div ng-repeat="book in books | filter:filterobj">...</div>

see, also, short demo.

if want let user dymanically specify field filter by, can (although not common practice):

filter by: <input type="search" ng-model="dynamicfield"        placeholder="field filter by" /> <input type="search" ng-model="filterobj[dynamicfield]"        placeholder="value filter by" /> <div ng-repeat="book in books | filter:filterobj">...</div>
