我正在尝试从存储中获取数据。我想在 extjs 面板中的表格布局中使用它,但尽管数据打印在控制台中,但总是得到一个空字符串。任何指针将不胜感激。
<code>
Ext.onReady(function(){
Ext.define('Account', {
extend: 'Ext.data.Model',
fields: [
'id',
'name',
'nooflicenses'
]
});
var store = Ext.create('Ext.data.Store', {
model: 'Account',
autoSync: true,
proxy: {
type: 'ajax',
api: {
read: "accounts"
},
reader: {
type: 'json',
root: 'Account',
successProperty: 'success',
messageProperty: 'message',
totalProperty: 'results',
idProperty: 'id'
},
listeners: {
exception: function(proxy, type, action, o, result, records) {
if (type = 'remote') {
Ext.Msg.alert("Could not ");
} else if (type = 'response') {
Ext.Msg.alert("Could not " + action, "Server's response could not be decoded");
} else {
Ext.Msg.alert("Store sync failed", "Unknown error");}
}
}//end of listeners
}//end of proxy
});
store.load();
store.on('load', function(store, records) {
for (var i = 0; i < records.length; i++) {
console.log(store.data.items[0].data['name']); //data printed successfully here
console.log(store.getProxy().getReader().rawData);
console.log(store);
};
});
function syncStore(rowEditing, changes, r, rowIndex) {
store.save();
}
var rowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
clicksToMoveEditor: 1,
autoCancel: false,
saveText: 'Save',
listeners: {
afteredit: syncStore
}
});
var grid = Ext.create('Ext.panel.Panel', {
title: 'Table Layout',
width: 500,
height:'30%',
store: store,
layout: {
type: 'table',
// The total column count must be specified here
columns: 2,
tableAttrs: {
style: {
width: '100%',
height:'100%'
}
},
tdAttrs: {
style: {
height:'10%'
}
}
},
defaults: {
// applied to each contained panel
bodyStyle:'border:0px;',
xtype:'displayfield',
labelWidth: 120
},
items: [{
fieldLabel: 'My Field1',
name :'nooflicenses',
value: store //How to get the data here
//bodyStyle:'background-color:red;'
},{
fieldLabel: 'My Field',
name:'name',
value:'name'
}],
renderTo: document.getElementById("grid1")
});
});
