angularjs - How to find an array object according to given information? -


i have array in angularjs controller this:

$scope.persons = [{name:'joey', age:'27'},{name:'lucy', age:'22'}]

i have got name 'lucy', how can age of name in controller (not in html)?

i've created plunk here outlines single result, age, multiple results.

this implemented within filter, documented on angular site here: https://docs.angularjs.org/api/ng/filter/filter

https://plnkr.co/edit/ofrmzpqrzftonafyjp7z?p=info

angular.module('plnk',[]).controller('plnkctrl', function($scope){    // note, added second joey here test multiple function.   // output, check browser console.    $scope.persons = [{name:'joey', age:'27'},{name:'joey', age:'28'},{name:'lucy', age:'22'}]    console.log('single -> ', getagesingle('lucy'));   console.log('multiple ->',getagemultiple('joey'));    function getagemultiple(personlookup) {      var results = [];     angular.foreach($scope.persons,function(person){        if (person.name === personlookup) {          results.push(person);          // or results.push(person.age) age        }      });     return results;    }    function getagesingle(personlookup) {     var result = '';     angular.foreach($scope.persons,function(person){        if (person.name === personlookup && !result) {          result = person.age;        }      });     return result;   }  });

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
