Jquery how to find an Object by attribute in an Array

Question

Given I have an array of \"purpose\" objects:

//array of purpose objects:
var purposeObjects = [
    {purpose: \"daily\"},
    {purpose: \"weekly\"},
    {pu         


        

Answer 1

The error was that you cannot use this in the grep, but you must use a reference to the element. This works:

function findPurpose(purposeName){
    return $.grep(purposeObjects, function(n, i){
      return n.purpose == purposeName;
    });
};

findPurpose("daily");

returns:

[Object { purpose="daily"}]
