Extjs 分页查询的参数问题

先按条件查询数据，再点下一页保留住查询条件,解决方案是将查询参数放入到store.baseParam中  
  
storeMain.on('beforeload', function(thiz, options)\{  
    Ext.apply(thiz.baseParams, \{  
        msg: Ext.get('title').dom.value//查询条件  
    \});  
\});  
  
Js代码  
store: new Ext.data.JsonStore(\{    
            storeId: 'in\_grid\_store',    
            pageSize: 20,    
            totalProperty: 'totalCount',    
            remoteSort: true,    
            url: 'incoming/list.do',    
            root: 'incomings',    
            listeners :\{    
                beforeload :\{    
                    fn : function(thiz,options)\{    
                        Ext.apply(thiz.baseParams, Ext.getCmp('in-query-form').form.getValues());     
                    \}    
                \}    
            \},    
            fields: \['id', 'batch', 'customer', \{name:'pigCount', type: 'int'\}, 'createDate','status'\]    
        \}),   
  
store: new Ext.data.JsonStore(\{  
storeId: 'in\_grid\_store',  
pageSize: 20,  
totalProperty: 'totalCount',  
remoteSort: true,  
url: 'incoming/list.do',  
root: 'incomings',  
listeners :\{  
beforeload :\{  
fn : function(thiz,options)\{  
Ext.apply(thiz.baseParams, Ext.getCmp('in-query-form').form.getValues());  
\}  
\}  
\},  
fields: \['id', 'batch', 'customer', \{name:'pigCount', type: 'int'\}, 'createDate','status'\]  
\}),   
function beforeload() 即将Form表单中的参数放入store.baseParam中  
  
  
daglds.on('beforeload', function() \{      
     var dkbh = dagldkbh.getValue();  
     var pname = daglpname.getValue();  
     var acc = daglacc.getValue();  
     var dwbh = dagldwbh.getValue();  
     var dwmc = dagldwmc.getValue();  
     var fkyh = daglfkyh.getValue();  
     var dkrqs = dagldkrqstar.getValue();  
     var dkrqe = dagldkrqend.getValue();  
     var dkzt = dagldkzt.getValue();  
     var dkjed = dagldkjedy.getValue();  
     var dkjex = dagldkjexy.getValue();  
     var dkqxd = dagldkqxdy.getValue();  
     var dkqxx = dagldkqxxy.getValue();  
             this.baseParams = \{  
                   dkbh : dkbh,  
                    pname : pname,  
                    acc : acc,  
                    dwbh : dwbh,  
                    dwmc : dwmc,  
                    fkyh : fkyh,  
                    dkrqs : dkrqs,  
                   dkrqe : dkrqe,  
                    dkzt : dkzt,  
                    dkjed : dkjed,  
                    dkjex : dkjex,  
                     dkqxd : dkqxd,  
                    dkqxx : dkqxx  
                      \};  
             \});  
  
我写的这个事件表示，当Store作load()方法之前，将我的查询条件加入到load()中的条件去。
