弱弱的问：extjs的 ext-all-debug.js错误，怎么办？

Question

me["onBeforeItem" + map[newType]] is not a function
[在此错误处中断] (me['onBeforeItem' + m...record, item, index, e) === false) ||   ext-all-debug.js (第 66872 行)
前面我写的js调试也没发现错误，这样的怎么找到bug呢？求解，谢谢了。

Answer 1

我排除了全部多余的代码，
用的是extjs4.0 Ext.onReady(function() {            //创建对象模型
            Ext.define('Item', {
                extend: 'Ext.data.Model',
                fields: [
            { name: 'MaterialId', type: 'int' },
            { name: 'MaterialCode', type: 'string' },
            { name: 'Quantity', type: 'int' }
        ]
            });
            //创建 子单的数据源
            var Itemstore = Ext.create('Ext.data.JsonStore', {
                storeId: 'simpsonsStore',
                autoDestroy: true,
                autoLoad: false,
                model: 'Item',
                fields: ['MaterialId', 'MaterialCode', 'Quantity'],
                proxy: {
                    type: 'ajax',
                    url: '/WareHouseVoucherItem/Select',
                    reader: {
                        type: 'json',
                        root: 'rows',
                        totalProperty: 'totalCount'
                    }
                }
            });
            //可编辑行的创建
            var rowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
                clicksToMoveEditor: 1,
                autoCancel: false
            });            //从表添加mine
            var grid = Ext.create('Ext.grid.Panel', {
                title: '子单信息',
                store: Itemstore,
                autoHeight: true,
                columns: [{
                    text: '物资编号',
                    dataIndex: 'MaterialId',
                    width: 130,
                    editor: {
                        xtype: 'textfield',
                        name: 'MaterialId',
                        id: 'MaterialId'
                    }
                }, {
                    text: '数量',
                    dataIndex: 'Quantity',
                    width: 60,
                    editor: {
                        xtype: 'numberfield',
                        id: 'Quantity',
                        name: 'Quantity',
                        minValue: 1,
                        maxValue: 100000
                    }
                }, {
                    text: '编号',
                    dataIndex: 'MaterialCode',
                    width: 120,
                    editor: {
                        id: 'MaterialCode'
                    }
                }
                ],
                region: 'center',
                tbar: [{
                    text: '添加',
                    itemId: 'addItems',
                    handler: function() {
                        rowEditing.cancelEdit();                        var r = Ext.ModelManager.create({
                            MaterialId: 1,
                            Quantity: 20,
                            MaterialCode: 'sfg001',
                            indoor: false
                        }, 'Item');                        Itemstore.insert(0, r);
                        rowEditing.startEdit(0, 0);
                    }
}],
                    plugins: [rowEditing]
                });                var center = { region: "center", split: true, border: false, items: grid, layout: "fit" };
                new Ext.Viewport({ layout: "border", items: [center] });
            });

Answer 2

不清楚你创建的Item对象模型是不是关键字了

Answer 3

 totalProperty: 'totalCount'有这个了 为什么你没pageSize呢

Answer 4

我已解决，把官网的ext-all-debug.js文件覆盖项目中的那个，就没报错了。

Answer 5

难道你开始导入到项目中的ext-all-debug不是官网的吗，我也老是遇到events报错，不知道我代码那里不规范，希望你能给点心得，谢谢
