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,
        &n
