How to use array include in multidimension array angular 2

Question

hi this is my array

this.testArray = [{ "office_id": "1", "officename": "sun" }, { "office_id": "2", "officename": "moon" }];

i want to check whether officename sun is there or not. I tried used include
this.testArray.includes("sun") but this will work for one dimension array( it will return true). how if I want to use it for this multidimension array. it always return false.

** this.testArray.includes("sun") This will work with this array
**

this.testArray = ["sun","moon","stars" }];

it will return true it exist. but it is not working with my array the up one.

Can you give the sample multidimensional array you are using because the one you provided is not multidimensional — Vohid Karimov

Your array is not multidimensional. However you can do it like :

testArray.find(function(i){
   return (i.officename === 'sun');
});

you can create a function in your controller and call it from html. See this working fiddle

In case you need a filter directly

| filter:{officename:'sun'}

or negative

| filter:{officename:'!sun'}

Simply you can check value include or not by using underscorejs find function

this.testArra = [{ "office_id": "1", "officename": "sun" }, { "office_id": "2", "officename": "moon" }]

var temp =  _.find(this.testArra, function (o) { return o.officename==='sun2'; })

if temp "undefined" value not include, else value include

you can use find method in javascript

ES6 demo

var testArray = [{ "office_id": "1", "officename": "sun" }, { "office_id": "2", "officename": "moon" }];

var arr = testArray.find(o=> o.officename === "sun");

console.log(arr)

ES5 demo

var testArray = [{ "office_id": "1", "officename": "sun" }, { "office_id": "2", "officename": "moon" }];

var arr = testArray.find(function(o){
   return  o.officename === "sun"
});

console.log(arr)
