我有"复杂"的数据——这意味着我的数据中存在关联——并且我试图在我的网格中使用这些关联。我根据一些数据创建列,因为数据嵌套在数组中,所以我为每个列设置了一个渲染器……我还设置了一个编辑器。渲染器工作得很好,但是设置编辑器的值并没有像我想象的那样工作。下面是我的代码(和Fiddle):
Ext.application({
name : 'Fiddle',
launch : function() {
Ext.define('Phone', {
extend: 'Ext.data.Model',
fields: [
{name: 'phone', type: 'int'},
{name: 'type', type: 'string'}
]
});
Ext.define('Person', {
extend: 'Ext.data.Model',
fields: [
{name: 'name', type: 'string'}
],
hasMany: [
{associationKey: 'phones', model: 'Phone', name: 'getPhonesStore'}
]
});
var beforeEdit = function(editor, context, eOpts) {
var grid = context.grid;
var record = context.record;
if (grid && record) {
var phonesStore = record.getPhonesStore();
var columns = grid.columns;
if (columns && phonesStore) {
for (var i = 1; i < columns.length; i++) {
var column = columns[i];
if (column) {
var editor = column.getEditor();
if (editor) {
alert(phonesStore.getAt(i - 1).get('phone'));
editor.setValue(phonesStore.getAt(i - 1).get('phone'));
}
}
}
}
}
};
Ext.define('MyView', {
extend: 'Ext.grid.Panel',
store: Ext.create('Ext.data.Store', {
model: 'Person',
proxy: {
type: 'memory'
},
data: [
{name: 'blah', phones: [{phone: 123456789, type: 'Home'}, {phone: 9999999999, type: 'Cell'}]},
{name: 'bleh', phones: [{phone: 222222222, type: 'Home'}, {phone: 1111111111, type: 'Cell'}]}
]
}),
plugins: [
{ptype: 'rowediting', clicksToEdit: 1, listeners: {beforeedit: beforeEdit}}
],
height: 300,
width: 400,
initComponent: function() {
var store = this.getStore();
if (store) {
var firstRecord = store.first();
if (firstRecord) {
var phonesStore = firstRecord.getPhonesStore();
if (phonesStore) {
var columns = [{
xtype: 'gridcolumn',
dataIndex: 'name',
text: 'Name',
editor: {
xtype: 'textfield',
hideTrigger: true
}
}];
phonesStore.each(function(phoneRec) {
columns.push({
xtype: 'gridcolumn',
text: phoneRec.get('type'),
renderer: this.phoneRenderer,
editor: {
xtype: 'numberfield',
hideTrigger: true
}
});
}, this);
this.columns = columns;
}
}
}
this.callParent();
},
phoneRenderer: function(value, metaData, record, rowIndex, colIndex) {
return record.getPhonesStore().getAt(colIndex - 1).get('phone');
}
});
Ext.create('MyView', {
renderTo: Ext.getBody()
});
}
});
我总共有3列…Name
, Home
, Cell
。现在你可能会想,为什么我不只是有一个单元格和Home对象,而不是phones
数组…好吧,这不是我想要做的,因为我不认为这是如何正确地构建这些数据。无论如何,当我初始化我的网格时,我创建了这两个额外的列。
问题来自于我为"Home"one_answers"Cell"列设置的编辑器…因为我使用的是嵌套数据,没有适当的dataIndex,所以当编辑器呈现时,它对编辑器有一个空值。所以我想尝试进入beforeedit事件,我可以得到我的值,但不幸的是,它看起来不像我可以设置编辑器的值,因为我假设starttedit方法有一些诡计。
你会看到,当你点击一行时,它会提醒我想在编辑器中设置的Home和Cell值,但是在编辑器中使用setValue不起作用…有谁能告诉我该怎么做吗?
当单击行时,我可以通过使用setEditor方法(在列上)来解决这个问题:

var columns = grid.getView().getGridColumns();
if (columns && phonesStore) {
for (var i = 1; i < columns.length; i++) {
var column = columns[i];
if (column) {
column.setEditor({
xtype: 'numberfield',
