Question

我的应用程序中有此代码，但这不会加载任何数据。数据是可访问的，但不会显示在我的网格面板中，任何人都有想法，为什么？

 Ext.onReady(function () {
        Ext.QuickTips.init();
        Ext.form.Field.prototype.msgTarget = 'side';

        var btnAdd = new Ext.Button({
            id: 'btnAdd',
            text: 'Adicionar',
            iconCls: 'application_add',
            handler: function (s) {

            }
        });
        var btnEdit = new Ext.Button({
            id: 'btnEdit',
            text: 'Editar',
            iconCls: 'application_edit',
            handler: function (s) {

            }
        });
        var btnRemove = new Ext.Button({
            id: 'btnRemove',
            text: 'Apagar',
            iconCls: 'application_delete',
            handler: function (s) {

            }
        });

        var tbar = new Ext.Toolbar({
            items: [btnAdd, btnEdit, btnRemove]
        });

        var formFind = new Ext.FormPanel({            
            height: 100
        });

        var store = new Ext.data.JsonStore({
            remoteSort: true,
            idProperty: 'ContentId',
            root: 'rows',
            totalProperty: 'results',
            fields: [
                { name: 'ContentId', type: 'int' },
                { name: 'Name' },
                { name: 'Version' },
                { name: 'State' },
                { name: 'CreatedDateTime' },
                { name: 'PublishedDateTime'},
                { name: 'CreatedByUser' },
                { name: 'PublishedByUser' }
            ],
            proxy: new Ext.data.ScriptTagProxy({
                url: '/Admin/ArticleList'
            })
        });
        store.setDefaultSort('ContentId', 'desc');

        var paging = new Ext.PagingToolbar({
            store: store,
            pageSize: 25,
            displayInfo: true,
            displayMsg: 'Foram encontrados {2} registos. Mostrando {0} de {1}',
            emptyMsg: "Nenhum registo encontrado."
        });

        var grid = new Ext.grid.GridPanel({
            id: 'grid',
            height: 700,
            store: store,
            loadMask: true,
            loadingText: 'Carregando...',
            autoHeight: true,
            cm: new Ext.grid.ColumnModel ([
                { id: 'ContentId', dataIndex: 'ContentId', header: 'Identif.', width: 60, sortable: true },
                { id: 'Name', dataIndex: 'Name', header: 'Titulo', width: 75, sortable: true },
                { id: 'Version', dataIndex: 'Version', header: 'Versão', width: 75, sortable: true },
                { id: 'State', dataIndex: 'State', header: 'Estado', width: 75, sortable: true },
                { id: 'CreatedDateTime', dataIndex: 'CreatedDateTime', header: 'Data de Criação', width: 85, sortable: true },
                { id: 'PublishedDateTime', dataIndex: 'PublishedDateTime', header: 'Data de Publicação', width: 75, sortable: true },
                { id: 'CreatedByUser', dataIndex: 'CreatedByUser', header: 'Criado por', width: 75, sortable: true },
                { id: 'PublishedByUser', dataIndex: 'PublishedByUser', header: 'Publicado por', width: 85, sortable: true }
            ]),
            stripeRows: true,
            viewConfig: { forceFit: true },
            bbar: paging
        });

        var panel = new Ext.Panel({
            id: 'panel',
            renderTo: Ext.getBody(),
            layout: 'fit',
            tbar: tbar,
            items: [grid]
        });

        store.load(); // trigger the data store load
    });

您不应该使用ScriptTagProxy。如果您阅读文档，您将看到它仅在有限的情况下用于以特定格式从远程服务器检索上下文。

你想要一个HttpProxy。

Extjs中的GridPanel未加载
