update:

in controller:

ctrl.items = [{ name: 'ape', id:1 }, { name: 'john', id:2 }]; 

in template:

<input type='hidden' value="{{ ctrl.items | map: 'name|id' | join: ',' }}" > 

expected output:

<input type='hidden' value="ape|1,john|2" > 

you have create custom filter form value mentioned you.

var app = angular.module('myapp', []); app.filter('map', function() {   return function(input, propname) {   var prop = propname.split("|");   return input.map(function(item) {   return item[prop[0]] +"|"+ item[prop[1]];    });   }; });
