我在 ExtJS 4.2 中向商店/网格添加新条目时遇到问题。创建操作在服务器上运行并为新记录返回生成的 id。我可以开始编辑网格中未显示的行。同步后我得到的错误是:Uncaught TypeError: Cannot read property 'parentNode' of null
.
项目商店.js:
var projectStore = Ext.create('Ext.data.Store', {
model: 'ProjectModel',
storeId: 'projectStore',
autoLoad: true,
autoSync: true,
proxy: {
type: 'ajax',
api: {
create: webPath+'server.php?action=createProjectStore',
read: webPath+'server.php?action=readProjectsStore',
update: webPath+'server.php?action=updateProjectStore',
destroy: webPath+'server.php?action=destroyProjectStore'
},
extraParams: {
token: userDetails.token,
userName: userDetails.UserName
},
reader: {
type: 'json',
successProperty: 'success',
idProperty: "ProjectID",
root: 'data',
messageProperty: 'message'
},
writer: {
type: 'json',
writeAllFields: true,
root: 'data',
encode: true,
allowSingle: false
},
listeners: {
exception: function(proxy, response, operation){
// Ext.MessageBox.show({
// title: 'REMOTE EXCEPTION',
// msg: operation.getError(),
// icon: Ext.MessageBox.ERROR,

// });
operation.records[0].reject();
}
},
onUpdateRecords: function(records, operation, success) {
console.log(records);
}
}
});
项目模型.js:
