Find object by its property in array of objects with AngularJS way

Question

I have a array like below

var myArray = [{'id':'73','name':'john'},{'id':'45','name':'Jass'}, etc.] 

Now I have an id 73 how to select this particular object from the array. I see I can do this in jQuery easily with grep Is there any angular way of doing this?

Since most user developing app with angular always get data from array of objects(mostly for table) there should be a helper function for this?

So that I can change the data of the row with the ID of the row by updating the array of object.

I don't want to bind this in view. I want to manipulate the data and update the data withing function.

For Example. I have a table listing. If end user edit a row from the table I have the ID of the object so after end user hit save, I need to update the array and then back to table listing.

Answer 1

you can use angular's filter https://docs.angularjs.org/api/ng/filter/filter

in your controller:

$filter('filter')(myArray, {'id':73})  

or in your HTML

{{ myArray | filter : {'id':73} }} 

Answer 2

How about plain JavaScript? More about Array.prototype.filter().

var myArray = [{'id': '73', 'name': 'john'}, {'id': '45', 'name': 'Jass'}]    var item73 = myArray.filter(function(item) {    return item.id === '73';  })[0];    // even nicer with ES6 arrow functions:  // var item73 = myArray.filter(i => i.id === '73')[0];    console.log(item73); // {"id": "73", "name": "john"}
