见我的上一篇文章,XCodeBuilder不仅能生成.Net三层代码,还生成处理层代码和Ext脚本,以下是一个grid的示例。 本文件为:ext_editgrid_products.js,用来显示,编辑,删除products表的数据。
复制代码 代码如下:

var productsgrid;
var productsstore;
var productslimit = 25; //每页显示条数
var productsListPostUrl = "/management/procrequest/Proc_products.ashx?action=getlist";
var productsModifyPostUrl = "/management/procrequest/Proc_products.ashx?action=modify";
var productsDeletePostUrl = "/management/procrequest/Proc_products.ashx?action=del";
function initproductsGrid(containerid) {
Ext.menu.RangeMenu.prototype.icons = {
gt: 'images/greater_then.png',
lt: 'images/less_then.png',
eq: 'images/equals.png'
};
Ext.grid.filter.StringFilter.prototype.icon = 'images/find.png';
Ext.QuickTips.init();
function formatDate(value) {
return value ? value.dateFormat('M d, Y') : '';
};
var fm = Ext.form;
var sm = new Ext.grid.CheckboxSelectionModel();
var cm = new Ext.grid.ColumnModel([
sm,
{
id:'productId',
header: '产品编号',
dataIndex: 'productId',
sortable: true,
width:70,
editor: new fm.NumberField({
allowBlank: false,
allowNegative: false
})
},
{
header: '产品名称',
dataIndex: 'productName',
sortable: true,
width:120,
editor: new fm.TextField({
allowBlank: false,
allowNegative: false
})
},
{
header: '金额',
dataIndex: 'money',
sortable: true,
width:120,
editor: new fm.NumberField({
allowBlank: false,
allowNegative: false
})
},
{
header: '地址',
dataIndex: 'address',
sortable: true,
width:120,
editor: new fm.TextField({
allowBlank: false,
allowNegative: false
})
},
{
header: '电话',
dataIndex: 'tel',
sortable: true,
width:120,
editor: new fm.TextField({
allowBlank: false,
allowNegative: false
})
},
{
header: '备注',
dataIndex: 'remark',
sortable: false,
width:550,
editor: new fm.myHtmlEditor({
allowBlank: false,
allowNegative: false
})
},
{
header: '端口',
dataIndex: 'port',
sortable: true,
width:70,
editor: new fm.NumberField({
allowBlank: false,
allowNegative: false
})
}
]);
cm.defaultSortable = true;
/*
var Plant = Ext.data.Record.create([
]);
*/
productsstore = new Ext.data.JsonStore({
root: 'list',
totalProperty: 'totalCount',
idProperty: 'productId',
remoteSort: true,
fields: [
{name: 'productId' },{name: 'productName' },{name: 'money' },{name: 'address' },{name: 'tel' },{name: 'remark' },{name: 'port' }
],
proxy: new Ext.data.ScriptTagProxy({
url: productsListPostUrl
})
});
productsstore.setDefaultSort('productId', 'desc');
var filters = new Ext.grid.GridFilters({
filters: [
{ type: 'string', dataIndex: 'productId' }, { type: 'string', dataIndex: 'productName' }, { type: 'string', dataIndex: 'money' }, { type: 'string', dataIndex: 'address' }, { type: 'string', dataIndex: 'tel' }, { type: 'string', dataIndex: 'remark' }, { type: 'string', dataIndex: 'port' }
]
});
var pagingBar = new Ext.PagingToolbar({
pageSize: productslimit,
store: productsstore,
displayInfo: true,
displayMsg: '第 {0} - {1} 条记录,总共 {2} 条记录',
emptyMsg: "没有记录"
});
productsgrid = new Ext.grid.EditorGridPanel({
store: productsstore,
cm: cm,
sm: sm,
bodyStyle: 'width:100%',
autoWidth: true,
height: 620,
renderTo: containerid,
autoExpandColumn: 'productId',
frame: true,
clicksToEdit: 2,
plugins: [filters],
loadMask: true,
enableTabScroll: true,
tbar: [{
text: '添加',
tooltip: '添加新记录',
iconCls: 'add',
handler:function(){
openTab("addproducts", "添加products", null, initAddproductsForm);
}
},
'-', {
text: '编辑',
tooltip: '编辑选中记录',
iconCls: 'option',
handler: function() {
var selectedRow = productsgrid.getSelectionModel().getSelections();
if (selectedRow) {
var obj = selectedRow[0];
if (!obj)
return;
var id = obj.get("productId");
openTab("editproducts", "编辑products", null, initAddproductsForm, id, obj);
}
}
},
'-', {
text: '删除',
tooltip: '删除选中记录',
iconCls: 'remove',
handler: function() {
var selectedRow = productsgrid.getSelectionModel().getSelections();
Ext.MessageBox.confirm('Confirm', '你确定要删除你所选定的' + selectedRow.length + "项吗?", function(btn) {
if (btn == 'yes') {
if (selectedRow) {
for (var i = 0; i < selectedRow.length; i++) {
var obj = selectedRow[i];
var id = obj.get("productId");
productsstore.remove(obj);
$.ajax({
type: "POST",
url: productsDeletePostUrl,
dataType: "json",
data: "recordid=" + id,
success: function(msg) {
if (msg[0] && msg[0].string != "success")
productsstore.reload();
}
});
}
}
}
});
}
}],
bbar: pagingBar
});
productsstore.load({ params: { start: 0, limit: productslimit} });
productsgrid.on("afteredit", afterEdit, productsgrid);
function afterEdit(obj) {
var r = obj.record; //获取被修改的行
var fildname = obj.field; //获取被修改的列
var id = r.get("productId");
var fildval = obj.value;
$.ajax({
type: "POST",
url: productsModifyPostUrl,
dataType: "json",
data: { action: 'modify', fildname: fildname, id: id, fildval: fildval },
complete: function() {
},
success: function(msg) {
}
});
}
}

本文件为ext_add_products.js,用来添加或者编辑products表。
复制代码 代码如下:

var productsAddPostUrl = "/management/procrequest/Proc_products.ashx?action=add";
var productsUpdatePostUrl = "/management/procrequest/Proc_products.ashx?action=update";
function initAddproductsForm(containerid, idstr, rowObj) {
if (!idstr)
idstr = containerid;
var productsForm = new Ext.FormPanel({
labelWidth: 100, // label settings here cascade unless overridden
url: productsAddPostUrl,
frame: true,
bodyStyle: 'padding:5px 5px 0',
autoWidth: true,
defaults: { width: '350' },
defaultType: 'textfield',
renderTo: containerid,
items: [
{
xtype: 'hidden',
name: 'productId',
id: 'productId' + idstr,
value: null == rowObj ? null : rowObj.get("productId"),
readOnly: true
}
, {
xtype: 'textfield',
fieldLabel: '商品名称',
height: 20,
name: 'productName',
allowBlank: false,
value: null == rowObj ? null : rowObj.get("productName"),
id: 'productName' + idstr
}
, {

}

id: 'remark' + idstr
}
, {
xtype: 'numberfield',
fieldLabel: '端口',
height: 20,
name: 'port',
value: null == rowObj ? null : rowObj.get("port"),
id: 'port' + idstr
}
],
buttons: [{
text: '保存',
handler: function() {
if (!productsForm.form.isValid())
return;
productsForm.form.submit({
meghod: 'post',
url: !isNaN(idstr) && parseInt(idstr) > 0 ? productsUpdatePostUrl : productsAddPostUrl,
waitMsg: '正在保存,请稍候...',
success: function() {
Ext.MessageBox.show({
title: '保存结果',
msg: '保存成功',
buttons: Ext.MessageBox.OK,

});
},
failure: function() {
Ext.MessageBox.show({

buttons: Ext.MessageBox.OK,

});
}
});
}
}]
});
}
