jquery - Filter javascript object array by string array -

-

i have array of objects, this:

var companies = [     { "name" : "company 1",       "logo" : "/logo.gif" },     { "name" : "company 2",       "logo" : "/logo2.gif" },     { "name" : "company 3",       "logo" : "/logo3.gif" } ];

i want filter array values have name exists in array:

var mycompanies = [ "company 1", "company 3" ];

in example, data returned be:

var companies = [     { "name" : "company 1",       "logo" : "/logo.gif" },     { "name" : "company 3",       "logo" : "/logo3.gif" } ];

what's best way this?

you can use $.grep() new, filtered array, this

var result = $.grep(companies, function(e) {                 return $.inarray(e.name, mycompanies) != -1;              });

you can test here. note performs better $.each() loop, can test here: http://jsperf.com/each-vs-grep
