extjs自带分页, 载入数据时传入参数

如果extjs设置了ttbar

bbar:  new  Ext.PagingToolbar
                (
                    {
                        pageSize: pageSize,
                        store: gridData,
                        displayInfo:  true ,
                        displayMsg:  " 一共有{2}条数据 "
                    }
                ),

 

 

 gridData重新载入时会自动上传start,limit值,但自己有时要附加参数,可以如下:

  gridData.on( " beforeload " ,  function (currentStore, options) {
                currentStore.baseParams[ " dept_id " ]  =  curDepartID;
                currentStore.baseParams[ " Semester_ID " ]  =  curSemesterID;
            });

curDepartID, curSemesterID在外面定义的 通过其它方式赋值给他们
