Input Parameters

Returns

Type: Any

Returns the Json object from the passed array whose value (at the specified attribute) was closest to the specified value.

Examples

var items = [
    { "age": 10, "name": "Ethan" },
    { "age": 20, "name": "Annabelle" },
    { "age": 30, "name": "Grant" },
    { "age": 40, "name": "Terri" },
    { "age": 50, "name": "Ben" }
];

// find the item in the array whose 'age' is closest to 25 without going over
// note: the entire object for 'Annabelle' is returned
var item = tools.findByScale(items, "age", 25);

Remarks

Use this function when you have an array of Json objects and you want to find a particular object based on a numeric value comparison with a property common to all objects in the array.
