1.ajax

var requestConfig = {
 url : '/storage/assay/assaycollectionsample!isRenewable.action',
 params : {ids : ids},
 callback : function(options,success, response) {
  if(success){
   var json =Ext.util.JSON.decode(response.responseText);
   if (json.success) { 
    tempThis.doUpdate();
   }else{
    Ext.ux.LevitationMsgBox.msg('提示',json.result,5);
   }
  }else{
   Ext.ux.LevitationMsgBox.msg('提示','网络超时,请求失败！',5);
  }
 }
}
Ext.Ajax.request(requestConfig);

Ext.Ajax.request({ 
 url : '/organperson/pmjt-organ-person-relation!saveRelation.action',
 params : {
      },
 success : function(response,options) {
 },
 failure : function(response,options) {
 }
});

2.保存进度条

//当出现弹出窗口，进度条消失 
Ext.MessageBox.show({
   title : "提示",
   msg : "数据保存中...",
   progress : true,
   width : 300,
   wait : true,
   closable : true
  });

?

3.JsonCinfig的使用

JsonConfig jsonConfig = new JsonConfig();
jsonConfig.setExcludes(new String[]{ "hibernateLazyInitializer", "localSellCarryCoal"});
jsonConfig.registerJsonValueProcessor(java.sql.Timestamp.class, new DateJsonValueProcessor("yyyy-MM-dd"));
for(LocalSellCarryCoalItem item:items){
 json.append(JSONSerializer.toJSON(item,jsonConfig).toString());

4.Grid拖拽

listeners : {
    rowdblclick : function(grid, rowIndex, e) {
     var spList = grid.getStore().getAt(rowIndex).get("tisEffective");
     if (spList == "是") {
      grid.getStore().getAt(rowIndex)
        .set("tisEffective", "否");
     } else if (spList == "否") {
      grid.getStore().getAt(rowIndex)
        .set("tisEffective", "是");
     }
    },
    afterrender:function(){
     var thisGrid=this;
     //alert(thisGrid);
     /**//**  
         * 列表右键菜单  
         */  
              thisGrid.addListener('rowcontextmenu', rightClickFn);   
              var rightClick = new Ext.menu.Menu( {   
                 id : 'spotTSampleListGrid_rightClickCont',   
                 items : [ {

                      handler:function(){

             function rightClickFn(grid, rowIndex, e) {   
                  e.preventDefault();
                  thisGrid.rightClickRowIndex=rowIndex;
                  rightClick.showAt(e.getXY());   
             }; 
     /*

            notifyDrop : function(dd, e, data) {
