KendoUI之kendoGrid服务端分页

parameterMap:设定传递给服务器的当前页数与每页大小,django下用get方法有效,post方法无法取得这2个参数
shema.total:设定总行数
serverPaging: true //设定服务器来实现分页功能

var ds = new kendo.data.DataSource ({
    transport: {
        read: {
            url: 'xxx',
            type: 'GET',    //X GET
            dataType: 'json',
            contentType: 'application/json; charset=utf-8',
        }
        ,parameterMap: function (options, operation) {  //X
            if (operation == "read") {
                return {page:options.page,pageSize:options.pageSize};
            }
        }

    }
    ,schema: {
        total : function(d) {
            return {{task_counts}};
            //return 100000000000;   //总条数
        }
    }
    ,batch: true        //X
    ,pageSize: 15       //X
    ,serverPaging: true //X
});
