在kendo UI中获取模型字段值的语法

var Model = kendo.data.Model.define({
    fields: {
        field1: { type: "string" },
        field2: { type: "number" },
        field3: { type: "date" }
    }
});

var model = new Model({
    field1: "value1",
    field2: 123,
    field3: new Date()
});

var fieldValue1 = model.field1;
var fieldValue2 = model.field2;
var fieldValue3 = model.field3;

var fieldValue1 = model.get("field1");
var fieldValue2 = model.get("field2");
var fieldValue3 = model.get("field3");

var fieldValue1 = model["field1"];
var fieldValue2 = model["field2"];
var fieldValue3 = model["field3"];
