Ext2一些琐碎的知识点

var store = theGrid.getStore(); var args = store.baseParams;

//ext2生成store

var newStore = new Ext.data.Store({         fields: fields,         type: 'ajax',         url: SRM_CONTEXT + '/mdm/code/code!selectCodeInfoByCond4custom.action',         baseParams: {  //传递参数             "cond.tablecode": tablecode,             "cond.auditflag": args["cond.auditflag"],             "cond.querytype": "query",             "cond.specialcode": args["cond.specialcode"],             "cond.dydh": args["cond.dydh"],             "cond.freezepage": args["cond.freezepage"]         },         pageSize:50,         reader: new Ext.data.JsonReader({ //reader里的参数             type: 'json',             root: 'extendBeans',             totalProperty: 'extendBeans_num',             fields : fields        }),

        autoDestroy: true,         autoLoad:true     });     //更新并重构grid

    //这块我需要重新生成新的grid，只更换它的列和store，reconfigure()方法刚好满足我的需求     theGrid.reconfigure(newStore,  new Ext.grid.ColumnModel(columns));     theGrid.extcolumns=columns;  //重新放入列     //绑定新store，解决分页问题     theGrid.bottomToolbar.bind(newStore); //这块ext2的方法里面处理的不好，未封装完成，需手动处理bbar     //解决快捷查询问题     var header = Ext.getDom(theGrid.getId()+'SearchHeader');  //快捷查询需重置     header.style.display = "inline";     theGrid.syncSize();
