问题描述
我有一些存储，这是形成的数据.在面板上，它看起来如何fieldName"和文本字段(依赖于调用的表单).例如，在一个表单上显示名称文档"和字段，在另一个表单上显示:销售日期和日期字段.数据是动态形成的
I have some store, which is formed data. On panel it looks how "fieldName" and text field (in depension from invoked form). For example, on one form is displayed "name document" and field, on another: date of selling and date field. Data is formed dynamicly
这里是商店:
tableTempStore = new Ext.data.JsonStore({
url: objectUrlAddress,
baseParams: {
'objectID': objectID
},
root: 'Fields',
fields: [{
name: 'Type',
type: 'int'
}, {
name: 'Value'
}, {
name: 'IsRequired',
type: 'bool'
}, {
name: 'Identifier'
}, {
name: 'Data'
}],
listeners: {
load: function(obj, records) {
Ext.each(records, function(rec) {
var item = null;
switch (rec.get('Type')) {
case 0: // int
item = new Ext.form.NumberField();
item.id = rec.get('Identifier');
item.fieldLabel = rec.get('Hint');
var isRequired = rec.get('IsRequired');
item.anchor = '100%';
item.allowBlank = ! isRequired;
item.disabled = editDisabled;
item.value = rec.get('Data');
break;
case 1: // demical
item = new Ext.form.NumberField();
item.id = rec.get('Identifier');
item.fieldLabel = rec.get('Hint');
var isRequired = rec.get('IsRequired');
item.anchor = '100%';
item.allowBlank = ! isRequired;
item.allowDecimals = true;
item.disabled = editDisabled;
item.value = rec.get('Data');
break;
case 2: // text
item = new Ext.form.TextField();
item.id = rec.get('Identifier');
item.fieldLabel = rec.get('Hint');
item.anchor = '100%';
var isRequired = rec.get('IsRequired');
item.allowBlank = ! isRequired;
item.value = rec.get('Data');
if (item.id == 'DocumentName') {
if (optype == "create") {
item.disabled = false;
} else {
item.disabled = true;
}
} else {
item.disabled = editDisabled;
}
break;
case 3: // date
var isRequired = rec.get('IsRequired');
item = new Ext.form.DateField();
item.id = rec.get('Identifier');
item.format = 'd.m.y H:i';
item.allowBlank = ! isRequired;
item.value = rec.get('Data');
item.emptyText = 'дд.мм.гггг чч:мм';
item.fieldLabel = rec.get('Hint');
item.disabled = editDisabled;
item.anchor = '100%';
break;
case 4: // enum
var dataValues = Ext.util.JSON.decode(rec.get('EnumList'));
var dataArray = Object.keys(dataValues).map(function(k) { return [k, dataValues[k]] });
item = new Ext.form.ComboBox({
typeAhead: true,
triggerAction: 'all',
forceSelection:true,
editable: false,
hiddenName: rec.get('Identifier'),
mode: 'local',
store: new Ext.data.ArrayStore({
fields: [
{name: 'myId', type: 'string'},
{name: 'displayText'}
],
data: dataArray
}),
valueField: 'myId',
displayField: 'displayText',
disabled: editDisabled
});
item.id = '_' + rec.get('Identifier');
item.anchor = '100%';
item.fieldLabel = rec.get('Hint');
var isRequired = rec.get('IsRequired');
item.allowBlank = ! isRequired;
item.value = rec.get('Data');
break;
case 5: // SQL
var dataValues = Ext.util.JSON.decode(rec.get('EnumList'));
var dataArray = Object.keys(dataValues).map(function(k) { return [k, dataValues[k]] });
item = new Ext.form.ComboBox({
typeAhead: true,
width: '100%',
triggerAction: 'all',
forceSelection:true,
editable: false,
hiddenName: rec.get('Identifier'),
mode: 'local',
store: new Ext.data.ArrayStore({
fields: [
{name: 'myId', type: 'string'},
{name: 'displayText'}
],
data: dataArray
}),
valueField: 'myId',
displayField: 'displayText',
disabled: editDisabled
});
item.id = '_' + rec.get('Identifier');
item.anchor = '100%';
item.fieldLabel = rec.get('Hint');
var isRequired = rec.get('IsRequired');
item.allowBlank = ! isRequired;
item.value = rec.get('Data');
break;
}
if (item != null) {
grid.add(item);
tableValue = Ext.getCmp('propGrid').doLayout();
source[item.fieldLabel] = tableValue;
//grid.doLayout();
}
});
grid.setSource(source);
}
}
});
此代码适用于表单，但我需要使用属性网格.我知道，如何显示字段名称(文档名称"等)，但我不明白，如何显示文本字段等.对于表单，我使用了 doLayout.我该怎么做?
This code had worked with form, but I need to use Property Grid. I know, how displayed field name ("document name" and etc.), but I don't understand, how displayed text field or etc. For form I had used doLayout. How can I do this?
我尝试使用自定义编辑器，但他不使用商店！
I tryed used customEditors, but he don't work with store!
这是网格:
grid = new Ext.grid.PropertyGrid({
title: 'Properties Grid',
id: 'propGrid',
autoFill: true,
autoHeight: true,
width: 600
});
请帮帮我！
正在更新
这是更新商店:
someStore = new Ext.data.JsonStore({
storeId: 'myStore',
url: objectUrlAddress,
baseParams: {
'objectID' : objectID
},
root: 'Fields',
fields: [
{name: 'Hint'},
{name:'Type', type: 'int'},
{name: 'Value'},
{name: 'Index', type: 'int'},
{name: 'IsRequired', type:'bool'},
{name: 'Identifier'},
{name: 'EnumList'},
{name: 'Directory'},
{name: 'Data'}
]});
这是更新网格:
var mainGrid = new Ext.grid.EditorGridPanel({
id: 'tableId',
height:300,
width: '100%',
clicksToEdit:1,
frame: true,
store: someStore,
columns:
[
{header: 'Объект'},
{header: 'Значение', dataIndex: 'Value', editor: {xtype: 'textfield'},
getEditor: function(record) {
var xtype = null,
args = {
fieldLabel: record.get('Hint'),
allowBlank: !record.get('IsRequired'),
value: record.get('Data'),
disabled: false
};
switch (record.get('Type')) {
case 0: // int
xtype = 'Ext.form.field.Number';
args.allowDecimals = false;
break;
case 1: // decimal
xtype = 'Ext.form.field.Number';
args.allowDecimals = true;
break;
case 2: // text
xtype = 'Ext.form.field.Text';
break;
case 3: // date
xtype = 'Ext.form.field.Date';
args.emptyText = 'дд.мм.гггг чч:мм';
args.format = 'd.m.y H:i';
break;
case 4: // enum
case 5: // sql
var dataValues = Ext.util.JSON.decode(record.get('EnumList'));
var dataArray = Object.keys(dataValues).map(function(k) { return [k, dataValues[k]] });
xtype = 'Ext.form.field.ComboBox ';
args.store = new Ext.data.ArrayStore({
fields: [
{name: 'myId', type: 'string'},
{name: 'displayText'}
],
data: dataArray
});
break;
}
return new Ext.grid.CellEditor({
field: Ext.create(xtype, args)
});
}
}
]
});
但是桌子是空的，我做错了什么?！
But table is empty, what i doing wrong?!
推荐答案
Ext.create('Ext.data.Store', {
storeId: 'myStore',
fields:[ 'Type', 'Value', 'IsRequired', 'Identifier', 'Data'],
data: [
{
"Type": 0,
"IsRequired": false,
"Identifier": "id-1",
"Data": 1001
},
{
"Type": 0,
"IsRequired": true,
"Identifier": "id-2",
"Data": 2002
},
{
"Type": 1,
"IsRequired": true,
"Identifier": "id-3",
"Data": 0.71
},
{
"Type": 3,
"IsRequired": true,
"Identifier": "id-4",
"Data": "24.10.18 00:00"
}
]
});
Ext.create({
title: 'Properties Grid',
xtype: 'grid',
renderTo: Ext.getBody(),
height: 400,
width: 600,
plugins: ['cellediting'],
store: Ext.data.StoreManager.lookup('myStore'),

columns: [
{ text: 'Identifier', dataIndex: 'Identifier' },
{

},
getEditor: function(record) {
var xtype = null,
args = {
fieldLabel: record.get('Hint'),

console.log({

});
switch (record.get('Type')) {
case 0: // int

case 5: // sql
var dataValues = Ext.util.JSON.decode(record.get('EnumList'));
var dataArray = Object.keys(dataValues).map(function(k) { return [k, dataValues[k]] });

args.store = new Ext.data.ArrayStore({

});
break;
}
if (!xtype) {
return false;
}
return Ext.create('Ext.grid.CellEditor', {
field: Ext.create(xtype, args)
});
}
}
]
});
