Javascript - ExtJs - 组件 - 分页
服务端只需要返回如下格式的字符串，ExtJs就可以解析并自动生成分页数据。

服务端
如果分页的Aajx请求的是ASP.NET MVC的Action方法，则需要注意：首次请求页面时应返回视图，视图里的ExtJs被成功加载到客户端后才会开启Ajax请求，所以首次加载视图时应返回一个view而不可能是分页数据，视图渲染完毕后store才会发起Ajax请求到另一个Action，这时，你才能request到分页参数。而下面使用的是ashx文件，视图已经呈现，所以不存在像在Action方法中无法获取分页参数的问题。
namespace WebErp.Ashx
{
// Entity不支持返回多表，此处需要定义一个UserManager的派生，以便可以将查询结果中的DepartmentName和RoseName装入UnkonwObj
public class UnkonwObj:UserManager
{
public string DepartmentName { get; set; }
public string RoseName { get; set; }
}
public class RecordsHandler : IHttpHandler
{
public void ProcessRequest( HttpContext context )
{
var Response = context.Response;
var Request = context.Request;
Response.ContentType = "text/plain";
System.Text.StringBuilder s = new System.Text.StringBuilder ( );
//当前页码上的第一条记录的索引
int start = int.Parse ( context.Request [ "start" ] );
//每页显示几条记录
int limit = int.Parse ( context.Request [ "limit" ] );
//计算页码
int pageIndex = start / limit ;
//分页后的总页数
int pageCount = ;
//获取表的分页记录
int recordCount = ;
//jion句子
string tablejoin = "UserManagers inner join Departments on UserManagers.DepartmentId=Departments.DepartmentId inner join TbRoses on UserManagers.TbRoseId=TbRoses.TbRoseId ";
using ( var DBContext = new ErpContext ( ) )
{
//分页
var List = Pager.GetPageList<UnkonwObj> ( DBContext , tablejoin , "UserManagers.UserId" , "" , limit , pageIndex , "" , "" , "UserManagers.UserId" , ref recordCount);
//将记录序列化为Json格式的字符表示且分页必须加入totalProperty属性供客户端ExtJs获取并作出计算
s.Append ( JsonConvert.SerializeObject ( List , Formatting.Indented ).Insert ( , "root:" ).Insert ( , "totalProperty:" + recordCount + "," ).Insert ( , "{" ) ).Append("}");

下拉框智能提示
根据用户输入的关键字进行查询，将查询的数据显示在下拉项中，当用户从下拉项选中一条记录后，触发combobox的select事件，动态为GridPanel所绑定的Store添加查询参数，动态改变表格的数据。
function CreateStoreBySearchKey(options) {
var StoreID = options.StoreID;
var comboID = options.comboID;
var valueField = options.valueField;
var displayField = options.displayField;
var start = options.start;
var limit = options.limit;
var pageSize = options.pageSize;
var url = options.url;
var idProperty = options.idProperty;
var root = options.root;
var highlightColor = options.highlightColor;
var combobox = Ext.getCmp(comboID);
Ext.define(StoreID + "Model", {
extend: "Ext.data.Model",
fields: [
{ name: valueField, type: "int" },
{ name: displayField, type: "string" }
]
});
return Ext.create("Ext.data.Store", {
storeId: StoreID,
autoLoad: false,
model: StoreID + "Model",
pageSize: pageSize,
proxy: {
type: "ajax",
url: url,
extraParams: { params: { start: start, limit: limit } },
reader: {
type: "json",
totalProperty: "totalProperty",
idProperty: idProperty,
root: root
}
},
listeners: {
load: function (me, records) {
//高亮searchKey
var val = Ext.getCmp(comboID);
Ext.each(records, function (record) {
record.set(val.displayField, record.get(val.displayField).replace(new RegExp(val.getRawValue(), "gm"), "<b style='background:" + highlightColor + "'>" + val.getRawValue() + "</b>"));
});
}
}
});
}
调用CreateStoreBySearchKey函数将自动创建存储器和模型，不需要手动创建，但需为自动创建的Store显示地指定一个名称即可，如下所示：
xtype: "panel",
width: ,
border:false,
layout: 'anchor',
items: [
{
xtype: 'combobox',
id: "StockTableKeySearchCombo",
store: CreateStoreBySearchKey({

comboID: "StockTableKeySearchCombo",
displayField: "StockName",
valueField: "StockTableId",
url: "/Ashx/SearchByKey.ashx",
pageSize: ,
start: ,
limit: ,
idProperty: "StockTableId",
root: "root",
highlightColor: "yellow"
}),
displayField: 'StockName',
valueField: "StockTableId",
emptyText:"根据仓库名查询",
minChars: , //最小中文字符
typeAheadDelay: ,//等待用户输入文本的毫秒数
typeAhead: true,//配置了typeAheadDelay后可使用此项，表示用户输入的内容能完整匹配下拉列表中的某条记录时将自动把后半截内容追加到输入框
hideLabel: true,
hideTrigger: true,
enableKeyEvents :true,
anchor: '100%',
multiSelect: false,
queryDelay: ,
queryMode: 'remote',
listeners: {
//嵌入查询图标
afterrender: function () {
this.setFieldStyle("background: url(/Img/Ico/search.png) no-repeat 8px center;padding-left:26px;");
},
//没有输入项时折叠下拉框同时使GridPanel绑定的Store重载
keyup: function (field) {
if (field.getRawValue() == "") {
this.collapse(true);
Ext.getStore("StockTableStore").fireEvent("beforeload");
Ext.getStore("StockTableStore").reload();//重载
}
},
select: function (field, newVal, oldVal) {
var textVal = field.getRawValue();
var pureText = textVal.replace(/<[^>]+>/g, "");//去掉高亮的html标记
field.setValue(pureText);
Ext.getStore("StockTableStore").fireEvent("beforeload"); //用户输入了查询参数，手动触发GridPanel所绑定的Store的beforeload事件，在事件中添加了查询参数=当前用户选择的文本
Ext.getStore("StockTableStore").reload();//重载
}
},
queryParam: 'StockTableKeySearch', //查询参数变量名，默认为 query，服务端通过Request["query"]获取，此变量名可以自定义
listConfig: {
loadingText: '查找中.',
emptyText: '没有符合的数据'
},
pageSize: //下拉列表框的分页大小,大于0则自动创建分页栏
}
]
}

}
},
listeners: {
beforeload: function () {
var comboCmp = Ext.getCmp("StockTableKeySearchCombo");
var SearchKey = comboCmp.getRawValue(); //用户选中下拉选项中的某一项记录的文本
/*如果需要获取ID，用combobox.getValue()居然只能得到文本，可考虑用在combobox的存储器上findBy查找与当前选中项的文本相匹配的ID，如：
var stockNameSearchValue = comboCmp.getRawValue();
var mixcollections = comboCmp.getStore().queryBy(function (record, id) {
清除高亮的html后进行比较
return record.get("StockName").replace(/<[^>]+>/g, "") == SearchKey
});
if (mixcollections.getCount() != 0) {
mixcollections = mixcollections.getRange()[0];
SearchID = mixcollections.get("StockTableId"); 得到ID
}*/
//向Store追加查询参数
Ext.apply(this.proxy.extraParams, { SearchKey: SearchKey ? SearchKey : "", /*SearchID: SearchID ? SearchID : ""*/ });
}
}
});
// #endregion
combobox的查询分页：服务端根据用户输入的关键字进行查询，然后将数据显示在下拉框选项中：
string StockTableKeySearch= Request [ "StockTableKeySearch" ];//combobox的queryParam
GridPanel的查询分页：服务端根据用户选择的下拉框选项的文本进行查询：
string SearchKey = Request [ "SearchKey" ];
