Filter JavaScript Object by value -

i have object array:

var result = [ {     appaddress:"127.0.0.1",     name:"appserver1",     dbconnection:"" }, {     appadress:"",     name:"dbserver1",     dbconnection:"server=.;database=master;integrated security=sspi" }]; 

now need name values (into array), appaddress isn't empty. tried array.filter() , $.map() none of these methods seems want.

this tried:

var appservers = $.map(result, function (val, key) {     return (key == 'appaddress' && val.length > 0) ? key : null;     }); 

and

var appservers = result.filter(function (entry) {     return entry['displayname'];     }); 

for filtering can use filter , map methods of array. see below example.

array.prototype.filter docs

array.prototype.map docs

var result = [{    appadress: "127.0.0.1",    name: "appserver1",    dbconnection: ""  }, {    appadress: "",    name: "dbserver1",    dbconnection: "server=.;database=master;integrated security=sspi"  }];      // first solution  var out = result.filter(function(obj) {    return obj.appadress;  }).map(function(obj) {    return obj.name;  })    // second solution  var namesarr = [];  result.foreach(function(obj) {    if (obj.appadress) {      namesarr.push(obj.name);    }  });        document.queryselector('#out').innerhtml = json.stringify(out, undefined, 4);  document.queryselector('#out2').innerhtml = json.stringify(namesarr, undefined, 4);

first solution  <pre id="out"></pre>    <hr/>    second solution  <pre id="out2"></pre>
