我正在使用ExtJS3，我有一个Ext.grid.GridPanel，其中每行左边都有一个复选框。在顶部有两个按钮：'刷新'和'提交'。我希望能够选择多行并通过单击提交按钮提交所有行。正如现在我选择多行并点击提交时，它将提交第一个，然后从网格中删除该项，我必须再次点击提交（以前检查的行仍然被检查）。
如何更改以下代码以使提交按钮一次发送所有行？
var dataStore = new Ext.data.SimpleStore({ fields: [
{name: 'node'},
{name: 'ip'},
{name: 'groups'}
]});
var checkBoxSelMod = new Ext.grid.CheckboxSelectionModel();
var dataGrid = new Ext.grid.GridPanel ({
renderTo: document.body,
clickstoEdit: 2,
selModel : checkBoxSelMod,
xtype: 'grid',
layout: 'fit',
sm: new Ext.grid.CheckboxSelectionModel(),
tbar: [
{
text: 'Refresh',
icon: '$nroot/includes/extjs3/resources/images/slate/button/table_refresh.png',
cls: 'x-btn-text-icon',
handler: function() {
window.location = '$nroot/index.php/imaging/index';},
scope: this,
},
{
text: 'Submit Machine(s)',
icon: '$nroot/includes/extjs3/resources/images/slate/button/table_add.png',
cls: 'x-btn-text-icon',
handler: function() {
var sm = dataGrid.getSelectionModel();
var sel = sm.getSelected();
if (sm.hasSelection()) {
Ext.Msg.show({
title: 'Image Machine?',
buttons: Ext.MessageBox.YESNO,
msg: 'Continue with imaging (no undo!) process for server: '+sel.data.node+'?',
fn: function(btn){
if (btn == 'yes'){
var conn = new Ext.data.Connection();
conn.request({
url: '$nroot/index.php/imaging/image/',
params: {
action: 'delete',
node: sel.data.node,
mgmtip: sel.data.ip
},
success: function(resp,opt) {
dataGrid.getStore().remove(sel);
},
failure: function(resp,opt) {
Ext.Msg.alert('Error','Unable to image server - check debug logs');
}
});
}
}
});
}
}
}
],
store: dataStore,
columns: [
checkBoxSelMod,
{ id: 'node', header: "Node", width: 150, sortable: true, dataIndex: 'node'},
{ id: 'ip', header: "IP", width: 120, sortable: false, dataIndex: 'ip'},
{ id: 'groups', header: "Groups", width: 100, sortable: true, dataIndex: 'groups'},
],
stripeRows: true,
autoExpandColumn: 'node',
listeners: {
render: function(){ this.store.loadData(dataList); }
}
})});
当我将代码从getSelected更改为getSelections时，它会在页面加载时返回：
item type is invalid for AcceptItem action
我找不到任何显示使用提交为GridPanels进行多选的示例。有没有我可以参考的？
编辑，根据以下解决方案，我修改了代码，工作如下：
var sels = sm.getSelections();
if (sels.length > 0) {
var ips = [], nodes = [];
Ext.each(sels, function(sel) {
ips.push(sel.get('ip'));
nodes.push(sel.get('node'));
});
Ext.Msg.show({
title: 'Image Machine?',
buttons: Ext.MessageBox.YESNO,
msg: 'Continue with imaging (no undo!) process for servers: '+nodes.join(",")+'?',
fn: function(btn){
if (btn == 'yes'){
Ext.each(sels, function(sel) {
var conn = new Ext.data.Connection();
conn.request({
url: '$nroot/index.php/imaging/image/',
params: {
node: sel.get('node'),
mgmtip: sel.get('ip')
},
success: function(resp,opt) {
dataGrid.getStore().remove(sel);
},
failure: function(resp,opt) {
Ext.Msg.alert('Error','Unable to image server - check debug logs');
}
});
})
}
}
});
}
}

最简单的方法是遍历所选记录并为每条记录提出问题。
var sels = sm.getSelections();
Ext.each(sels, function(sel) {
var node = sel.get('node'),
ip = sel.get('ip');
Ext.Msg.show({
title: 'Image Machine?',
buttons: Ext.MessageBox.YESNO,
msg: 'Continue with imaging (no undo!) process for server: '+node+'?',
fn: function(btn){
if (btn == 'yes'){
var conn = new Ext.data.Connection();
conn.request({
url: '$nroot/index.php/imaging/image/',
params: {
action: 'delete',
node: node,
mgmtip: ip
},
success: function(resp,opt) {
dataGrid.getStore().remove(sel);
},
failure: function(resp,opt) {
Ext.Msg.alert('Error','Unable to image server - check debug logs');
}
});
}
}
});
});
但是，对于用户来说，获取DataGrid中选择的每一行的提示可能不太好。但是，如果您的服务（'$ nroot / index.php / imaging / image /'）支持发布多个项目，您可以询问用户一次并发布所有项目。即。
var sels = sm.getSelections();
if (sels.length > 0) {
var ips = [], nodes = [];
Ext.each(sels, function(sel) {
ips.push(sel.get('ip'));
nodes.push(sel.get('node'));
});
Ext.Msg.show({
title: 'Image Machine?',
buttons: Ext.MessageBox.YESNO,
msg: 'Continue with imaging (no undo!) process for servers: '+nodes.join(",")+'?',
fn: function(btn){
if (btn == 'yes'){
var conn = new Ext.data.Connection();
conn.request({
url: '$nroot/index.php/imaging/image/',
params: {
action: 'delete',
nodes: nodes,
mgmtips: ips
},
success: function(resp,opt) {
Ext.each(sels, function() { dataGrid.getStore().remove(this) });
},
failure: function(resp,opt) {
Ext.Msg.alert('Error','Unable to image server - check debug logs');
}
});
}
}
});
}
