javascript - How to filter an object array by a string with underscore.js -

this how object array looks like:

[   {"id":"1","name":"john"},   {"id":"2","name":"jose"},   {"id":"3", "name":"mike"} ] 

i want filter string "jo" can bring me first , second item.

how can make return objects in same "object array" form such this:

[   {"id":"1","name":"john"},   {"id":"2","name":"jose"} ] 

the object filtered on autocomplete dropdown menu created "select2.js" library.

this create using examples in stackoverflow far:

("something do" part have failed, other parts work well)

$parameterselect.select2({     data : {         results : $scope.parameters,         text : 'name'     }, // init selected elements value initselection    : function (element, callback) {     var initialdata = [];      $(element.val().split(",")).each(function () {         initialdata.push({             id  : this,             text:         });     });     callback(initialdata); }, formatselection : formatfunction, formatresult : formatfunction, multiple : true, formatloadmore   : 'loading more...', placeholder : "select parameters", // query pagination query            : function (q) {     var pagesize,     results;     pagesize = 20; // or whatever pagesize     results  = [];     if (q.term && q.term !== "") {     // heads up; _.filter function use underscore (actually lo-dash) here        results = _.filter(this.data, function (e) {             //something        });     } else if (q.term === "") {         results = this.data;     }     q.callback({         results: results.results.slice((q.page - 1) * pagesize, q.page * pagesize),         more   : results.results.length >= q.page * pagesize     }); } }); 

filter function tests regexp against name property of each element.

_.filter(array, function(elt) { return /jo/i.test(elt.name); })
