在我的ExtJS应用程序中,我使用EditorGridPanel来显示来自服务器的数据。JsonStore和JsonReader的问题
var applicationsGrid = new Ext.grid.EditorGridPanel({
region: 'west',
layout: 'fit',
title: '<img src="../../Content/img/app.png" /> Приложения',
collapsible: true,
margins: '0 0 5 5',
split: true,
width: '30%',
listeners: { 'viewready': { fn: function() { applicationsGridStatusBar.setText('Приложений: ' + applicationsStore.getTotalCount()); } } },
store: applicationsStore,
loadMask: { msg: 'Загрузка...' },
sm: new Ext.grid.RowSelectionModel({
singleSelect: true,
listeners: { 'rowselect': { fn: applicationsGrid_onRowSelect} }
}),
viewConfig: { forceFit: true },
tbar: [{
icon: '../../Content/img/add.gif',
text: 'Добавить'
}, '-', {
icon: '../../Content/img/delete.gif',
text: 'Удалить'
}, '-'],
bbar: applicationsGridStatusBar,
columns: [{
header: 'Приложения',
dataIndex: 'ApplicationName',
tooltip: 'Наименование приложения',
sortable: true,
editor: {
xtype: 'textfield',
allowBlank: false
}
}, {
header: '<img src="../../Content/img/user.png" />',
dataIndex: 'UsersCount',
align: 'center',
fixed: true,
width: 50,
tooltip: 'Количество пользователей приложения',
sortable: true
}, {
header: '<img src="../../Content/img/role.gif" />',
dataIndex: 'RolesCount',
align: 'center',
fixed: true,
width: 50,
tooltip: 'Количество ролей приложения',
sortable: true}]
});
当我使用JsonStore没有读者它的工作原理,但是当我尝试更新任何领域它使用的不是“更新”我的“创造”的网址。
var applicationsStore = new Ext.data.JsonStore({
root: 'applications',
totalProperty: 'total',
idProperty: 'ApplicationId',
messageProperty: 'message',
fields: [{ name: 'ApplicationId' }, { name: 'ApplicationName', allowBlank: false }, { name: 'UsersCount', allowBlank: false }, { name: 'RolesCount', allowBlank: false}],
id: 'app1234',
proxy: new Ext.data.HttpProxy({
api: {
create: '/api/applications/getapplicationslist1',
read: '/api/applications/getapplicationslist',
update: '/api/applications/getapplicationslist2',
destroy: '/api/applications/getapplicationslist3'
}
}),
autoSave: true,
autoLoad: true,
writer: new Ext.data.JsonWriter({
encode: false,
listful: false,
writeAllFields: false
})
});
我认为问题是我不使用阅读器,但是当我使用JsonReader网格停止显示任何数据。
var applicationReader = new Ext.data.JsonReader({
root: 'applications',
totalProperty: 'total',
idProperty: 'ApplicationId',
messageProperty: 'message',
fields: [{ name: 'ApplicationId' }, { name: 'ApplicationName', allowBlank: false }, { name: 'UsersCount', allowBlank: false }, { name: 'RolesCount', allowBlank: false}]
});
var applicationsStore = new Ext.data.JsonStore({
id: 'app1234',
proxy: new Ext.data.HttpProxy({
api: {
create: '/api/applications/getapplicationslist1',
read: '/api/applications/getapplicationslist',
update: '/api/applications/getapplicationslist2',
destroy: '/api/applications/getapplicationslist3'
}
}),
reader: applicationReader,
autoSave: true,
autoLoad: true,
writer: new Ext.data.JsonWriter({
encode: false,
listful: false,
writeAllFields: false
})
});
那么,有没有人知道问题可能是什么以及如何解决它。从我的服务器返回的数据是Json格式化和接缝要好
{"message":"test","total":2,"applications":[{"ApplicationId":"f82dc920-17e7-45b5-98ab-03416fdf52b2","ApplicationName":"Archivist","UsersCount":6,"RolesCount":3},{"ApplicationId":"054e2e78-e15f-4609-a9b2-81c04aa570c8","ApplicationName":"Test","UsersCount":1,"RolesCount":0}]}
正如我已经告诉了“身份证”选项也没有了,所以应该使用“STOREID”,而不是。 此外,问题与“POST VS PUT”没有任何关系。这家商店甚至不宁静。 – kalan 2010-06-10 06:31:09
