我有一个控制器和一个视图，并且想在选择项目时从控制器推送一条线。它在哪里说 onItemSelect: 那是我需要打电话的地方，但不知道如何......谢谢。
控制器是这样的：
Ext.define('Application.controller.ItemController', {
// Extend basic controller object
extend: 'Ext.app.Controller',
// Attach store classes to this controller
stores: ['Items'],
// Attach model classes to this controller
models: ['Item'],
// ..and last but not least - the view classes
views: ['item.List', 'item.Show'],
// Refs parameter defines references to certain
// instances of components pointed by selector
refs: [
{
// Ref determines the name of the automagic
// this.get[ref-goes-here] method that returns
// instance of certain component
ref : 'itemShowDesc',
// Select #item-description component in
// item.Show view
selector: 'itemShow > #item-description'
}
],
// when including the controllers in your application,
// the framework will automatically load the controller
// and call the init method on it
init: function() {
this.control({
'itemList' : {
// Action to be performed on select
select: this.onItemSelect
}
});
},
onItemSelect: function (selModel, selection) {
// Executed only when selection is a leaf
(selection.data.leaf) ? this.getItemShowDesc().addRow(selection.raw.description,'','','','','','') : null;
}
});
观点是这样的：
Ext.define('Application.view.item.Show', {
extend: 'Ext.grid.Panel',
alias : 'widget.itemShow',
requires: [
'Ext.selection.CellModel',
'Ext.grid.*',
'Ext.data.*',
'Ext.util.*',
'Ext.form.*',
'Application.model.Item'
],
xtype: 'cell-editing',
title: 'Favorite Books',
frame: true,
initComponent: function() {
this.cellEditing = new Ext.grid.plugin.CellEditing({
clicksToEdit: 1
});
Ext.apply(this, {
width: 680,
height: 350,
plugins: [this.cellEditing],
store: new Ext.data.Store({
// destroy the store if the grid is destroyed
autoDestroy: true,
model: Application.model.Item,
proxy: {
type: 'ajax',
// load remote data using HTTP
url: 'resources/data/grid/books.xml',
// specify a XmlReader (coincides with the XML format of the returned data)
reader: {
type: 'xml',
// records will have a 'plant' tag
record: 'book'
}
},
sorters: [{
property: 'common',
direction:'ASC'
}]
}),
columns: [{
header: 'Book Id',
dataIndex: 'item_id',
width: 100
}, {
header: 'Author',
dataIndex: 'author',
width: 100
}, {
header: 'Title',
dataIndex: 'title',
width: 250
},{
header: 'Description',
dataIndex: 'description',
width: 495
},{
header: 'Price',
dataIndex: 'price',
width: 70,
align: 'right',
renderer: 'usMoney'
},{
xtype: 'actioncolumn',
width: 30,
sortable: false,
menuDisabled: true,
items: [{
icon: 'resources/images/icons/delete.gif',
tooltip: 'Delete Plant',
scope: this,
handler: this.onRemoveClick
}]
}],
selModel: {
selType: 'cellmodel'
}
});
this.callParent();
this.on('afterlayout', this.loadStore, this, {
delay: 1,
single: true
})
},
addRow: function(inItemID,inDisplay,inSex,inAuthor,inTitle,inDescription,inPrice){
// Create a record instance through the ModelManager
var r = Ext.ModelManager.create({
item_id: inItemID,
display: inDisplay,
sex: inSex,
author: inAuthor,
title: inTitle,
description: inDescription,
price: inPrice
}, 'Item');
store.insert(0, r);
cellEditing.startEditByPosition({row: 0, column: 0});
}
,
loadStore: function() {
this.getStore().load({
// store loading is asynchronous, use a load listener or callback to handle results
callback: this.onStoreLoad
});
},
onStoreLoad: function(){
Ext.Msg.show({
title: 'Store Load Callback',
msg: 'Favorites were loaded, data available for processing',
icon: Ext.Msg.INFO,
buttons: Ext.Msg.OK
});
},
onRemoveClick: function(grid, rowIndex){
this.getStore().removeAt(rowIndex);
}
})
