Kendo the grid page parameter problem in the UI (1)

The grid in the Kendo UI is one of the longest-used controls, and when using the paging effect, we pass the paging parameter with our own defined parameters such as:

1 varDataSource =NewKendo.data.DataSource ({2 Transport: {3 read: {4URL: "Corresponding background path", 5ContentType: "Application/json",6Type: "POST", 7DataType: "JSON"8                 },9Parametermap:function(options, operation) {Ten                     if(Operation = = "read") { One                         varparameter = { A Page:options.page, - PageSize:options.pageSize, - Take:options.take, the Skip:options.skip -                         }; -                         returnkendo.stringify (parameter); -                     } +                 } -             }, +Serverpaging:true, APagesize:20, at Schema: { - Model: { -ID: "", -                 }, -Datafunction(response) { -                     returnResponse.data; in                 }, -Totalfunction(response) { to                     returnresponse.total; +                 } -             }, the});

The corresponding grid notation is:

$ ("#XXXX"). Kendogrid ({datasource:datasource, Height:, toolbar:kendo.template ($ ("#template"). HTML ()), pageable: {refresh:true, pagesizes:true, Buttoncount:5, page:1, PageSize:20, pagesizes: [20, 50, 100, 500]}, Columns: [{field:"XX", Title: "XX"}, {field:"XX", Title: "XX"}, {field:"XX", Title: "XX"}, {field:"XX", Title: "XX"}, {field:"XX", Title: "XX"},], selectable:"Row", sortable:true, resizable:true}). Data ("Kendogrid");

Background parsing method (Java backend) When:

@Override Publicstring XXX (string info) {Jsonobject json=Jsonobject.fromobject (info); PageBounds PageBounds=NewPageBounds (Integer.parseint (Json.get ("page"). ToString ()), Integer.parseint (Json.get ("PageSize"). toString ())); Map<String,Object> map =NewHashmap<string, object>();        //Note here defines an empty map that is not assigned, is for placeholder, and can be assigned if needed PageList<map<string, object>> list = (pagelist<map<string, object>>) xxxdao.xxx (PAGEBOUNDS,MAP); Try{List= (pagelist<map<string, object>>) xxxdao.xxx (PAGEBOUNDS,MAP); } Catch(Exception e) {logger.error ("Failed to get information list!" The specific information is: "+e); } jsonobject jsonobj=NewJsonobject (); Jsonobj.accumulate ("Data", Jsonarray.fromobject (list)); Jsonobj.accumulate ("Total", List.getpaginator (). Gettotalcount ()); returnjsonobj.tostring (); }

DAO Layer Impl Code
@Override public    List<Map<String,Object>> XXX (pagebounds pagebounds,map<string,object> map) {        return sqlsessiontemplate.selectlist ("xxdao.xxx", map,pagebounds);    }

In particular, it is important to note that the SelectList () is passed three parameters, the first one is known to be the path of the DAO layer, the second is the other parameters within the page (such as you need to upload from the foreground to the background of the user ID, etc.), the third is your resolution of the foreground grid paging parameters, If you do not need to pass other parameters to the page, the second parameter needs a variable placeholder , which can be null, a number, or an empty variable. If you do not wear parameters, you will get an error. cannot be resolved.
