Question

我遇到了Kendo Datasource的问题，在使用修改过的Object很好地解决了更改时，永远不会触发更新。

数据源非常简单：

    collection: new kendo.data.DataSource({
        autoSync: false,
        batch: true,
        transport: {
            read: {
                url: "http://localhost:81/GPL/Main/Sources/GPL.Web.MVC/Vignette/Vignettes_Read",
                dataType: "json" //"jsonp" is required for cross-domain requests; use "json" for same-domain requests
            },
            update: {
                url: "http://localhost:81/GPL/Main/Sources/GPL.Web.MVC/Vignette/Vignette_Update",
                dataType: "json" //"jsonp" is required for cross-domain requests; use "json" for same-domain requests
            },
            schema: {
                model: {
                    id: "Id"
                }
            }
        },
        change: function (e) {

            console.log(this);
            console.log(e);

            //Not working too
            //if (e.action == "itemchange") {
            //    debugger;
            //    vignettesViewModel.collection.pushUpdate(e.items[0]);
            //}

            $('.vignette').detach();
            for (var i = 0; i < vignettesViewModel.collection.data().length; i++) { 
                vignettesViewModel.createVignetteUI(vignettesViewModel.collection.data()[i]);                    
            }

            vignettesViewModel.init()
        }
    })

对于测试，autosync设置为false，批处理设置为true。

稍后在代码中，我更新了数据源，并通过sync（）方法解雇了数据源

    //Some logic up
        var data_hospit = vignettesViewModel.getByUid($(ui.element).data('uid'));
    //Another logic
        data_hospit.set('date_debut', cellDepart.data('date'));
        data_hospit.set('date_fin', cellArrivee.data('date'));
        data_hospit.set('PrenomNomEtDateDeNaissance', 'toto');

        vignettesViewModel.collection.sync();

更新未被触发，但我看到更改的对象通过更改功能。那么为什么更新从未被解雇？我已经很好地定义了具有id：'Id'的模型，如果我将更新字符串更改为虚拟函数alert（），这也不起作用。我试图用pushUpdate“强制”更新，但我收到错误“未定义的函数”

感谢您的帮助

schema不属于transport，您写道：

   transport: {
        read: {
            url: "http://localhost:81/GPL/Main/Sources/GPL.Web.MVC/Vignette/Vignettes_Read",
            dataType: "json" //"jsonp" is required for cross-domain requests; use "json" for same-domain requests
        },
        update: {
            url: "http://localhost:81/GPL/Main/Sources/GPL.Web.MVC/Vignette/Vignette_Update",
            dataType: "json" //"jsonp" is required for cross-domain requests; use "json" for same-domain requests
        },
        schema: {
            model: {
                id: "Id"
            }
        }
    },

应该是：

   transport: {
        read: {
            url: "http://localhost:81/GPL/Main/Sources/GPL.Web.MVC/Vignette/Vignettes_Read",
            dataType: "json" //"jsonp" is required for cross-domain requests; use "json" for same-domain requests
        },
        update: {
            url: "http://localhost:81/GPL/Main/Sources/GPL.Web.MVC/Vignette/Vignette_Update",
            dataType: "json" //"jsonp" is required for cross-domain requests; use "json" for same-domain requests
        }
    },
    schema: {
        model: {
            id: "Id"
        }
    }

更新不与Kendo数据源一起使用
