json格式实现批量删除

前端代码，将删除记录序列号组合成字符串传到后台

 'industryList button[action=deleteAll]' : {
                    click : function(button){
                    //    var agrid = button.findParentByType("gridpanel");
                        var agrid = button.ownerCt.ownerCt;
                        var data = agrid.getSelectionModel( ).getSelection();
                        if(data.length == 0){
                            Ext.Msg.alert('警告','请选择记录');
                        }else{
                            var mystore = agrid.getStore();
                            var aarray = [ ];
                            //序列号组合成字符串数组
                            Ext.Array.each(data,function(record){
                                var id = record.get('id');
                                aarray.push(id.toString());
                                console.log(id.toString());
                            });
                        
                            
                            Ext.Ajax.request({
                                url:'deleteAll.do',
                                //join（）函数将
                               // 数组元素组合成长字符串ids传到后台
                                params:{ids:aarray.join(",")},
                                method:'POST',
                                timeout:2000,
                                success:function(response,opts){
                                //    Ext.Array.each(data,function(record){
                                    //    st.remove(record);
                                //    })
                                    Ext.Msg.alert("删除操作","操作成功");
                                    var pagingObj = Ext.getCmp('ptb');
                                     pagingObj.doRefresh();
                                }
                        });
                        
                        }
                    }
                },

后端代码

@RequestMapping(value="/deleteAll",method=RequestMethod.POST)
    public void deleteAllIndustry(HttpServletRequest request,HttpServletResponse response){
        String ids = request.getParameter("ids");
        System.out.println(ids+"!!!!!!!!!!"+"deleteAll control层");
        String[] tokens = ids.split(",");
        
        for(String s : tokens){
            int p_key = Integer.valueOf(s);
            industryService.deleteIndustryById(p_key);
        }
        String msg = "{success : true}";
        try {
            response.getWriter().write(msg);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
