Extjs2.2 Itemselector的使用示例

我的广告单元，有空点一下哦，谢谢！

该窗体的js代码如下，（事前，请引用Itemselector相关的js文件，相css，图片，等）

Ext.namespace("Neo");
Ext.namespace("Neo.frontdesk");

Neo.frontdesk.SendMsg = Ext.extend(Ext.Window, {
title : '消息发送',
layout : 'fit',
width : 650,
height : 320,
id : 'sendmsgWin',
draggable : true,
modal : true,
frame : true,
resizable : true,
initComponent : function() {
   var cbmydstore =new Ext.data.Store( {
        id:"cbmydstore", 
        autoLoad : true, 
        proxy : new Ext.data.HttpProxy({url:"mgr/tsjy.htm?action=GetAllUser"}),   
        reader: new Ext.data.JsonReader({   
        root:"data"},   
        [{name:"fullname"}])
        });
   Ext.apply(this, {
    buttons : [{
     text : '发送',
     id : 'btnSubmit',
     handler : function() {
      var isForm=Ext.getCmp('sendmsgform');
      if(isForm.form.findField('msgdetails').getValue().trim().length<=0)
       {
        Ext.ux.Toast.msg('提示', '消息不能为空。');
        return;
       }
      if(isForm.form.findField('itemselector').getValue().trim().length>0){
                Ext.Ajax.request({
       url : 'mgr/tsjy.htm?action=addMsgs',
       success : function() {
        Ext.ux.Toast.msg('提示', '消息群发成功。');
        Ext.getCmp('sendmsgWin').close();
        var msggrid = Ext.getCmp('msgMenu');
         msggrid.getStore().reload();
       },
       failure : function(action) {
        if (action.failureType =='server') {
         obj = Ext.util.JSON
           .decode(action.response.responseText);
         Ext.Msg.alert('错误:', obj.errors.reason);
        }
       },
       params : {
        receivers : isForm.form.findField('itemselector').getValue(),

       }
      });
      }else{
       Ext.ux.Toast.msg('提示', '找不到信息接收者。');
      }
     }

    }, {
     text : '取消',
     id : 'btnCancel',

     }

   });
   Neo.frontdesk.SendMsg.superclass.initComponent.apply(this,
     arguments);

}
});

Ext.reg('sendmsg', Neo.frontdesk.SendMsg);




Java代码：

public void addMsgs(HttpServletRequest request, HttpServletResponse response)
throws Exception {

   log.info("Someone come from ip address <"+ request.getRemoteAddr()
     +">");
   log.debug("reach addMsgs");
   request.setCharacterEncoding("UTF-8");
   response.setContentType("text/json;charset=utf-8");
   String receivers = (String) request.getParameter("receivers").trim();
   String details=(String)request.getParameter("msgdetails").trim();
  
   SecurityContext ctx = SecurityContextHolder.getContext();
   User user = (User) ctx.getAuthentication().getPrincipal();
   Operator operator = businessService.findOperatorByOpUserName(user.getUsername());
   //获得群发人员名单
   String[] receiver=receivers.split(",");
   System.out.println(receiver.length);
   for(int i=0;i<receiver.length;i++)
   {
     System.out.println(receiver[i].toString());
     if(operator.getFullName().equals(receiver[i].toString())){}
     else{
     Msg msg=new Msg();
     msg.setReceiver(receiver[i].toString());
     msg.setSender(operator.getFullName());
     msg.setMsgdetails(details);
     msg.setSendtime(setTime());
     msg.setIsread("0");
     businessService.addNewMsg(msg);
     }
   }
   response.getWriter().write("{success: true}");
