在Javascript中搜索关联数组/哈希

Question

我有一个看起来像这样的数组

var data = [
 {"target": "production", "datapoints": [[165.0, 136], [141.0, 176], [null, 176]]},
 {"target": "test", "datapoints": [[169.0, 100], [151.0, 160], [null, 120]]},
 {"target": "backup", "datapoints": [[1.0, 130], [32.0, 120], [13.0, 130]]}
]

是否可以搜索此数组以返回包含的哈希值 "production"

{"target": "production", "datapoints": [[165.0, 136], [141.0, 176], [null, 176]]}

我查看了这个http://api.jquery.com/jQuery.inArray/,但不知道如何使用它.

你可以做:

var target = "production";
var result = $.grep(data, function(e){ return e.target == target; });

console.log(result);
