Json中获取记录的条数

Question

      $(document).ready(function () {
        var model_return = {
            "models":
                                           [
                                             { "id": "123", "name": "test1" },
                                             { "id": "456", "name": "jquery" }
                                           ]
        };
        alert(model_return.models[1].name);
    });
这个是一段Json数据，有没有办法能获取json中models的记录条数。

Answer 1

model_return.models.length
不过还是谢谢你提醒了我！！

Answer 2

$(document).ready(function () {
        var model_return = {
            "models":
                                           [
                                             { "id": "123", "name": "test1" },
                                             { "id": "456", "name": "jquery" }
                                           ]
        };
        alert(model_return.models.length);
        alert($(model_return.models).size());//jquery方法size和length是一样的
        alert(model_return.models[1].name);
    });
