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
