I'm using dojo 1.6 and I wanna create a store to connect to a grid; however, in dojo 1.6 only exists two ways with ItemFileWriteStore and store Memory which of these two is the best ?

I'm working with spring 2.5 for the controller.

不一定有一个“正确”的答案,但这里有一些事情需要考虑。

dojo/storeAPI 旨在成为下一步,取代dojo/data. 因此,dojo/store从最佳/现代实践的角度推荐。

但是,假设您正在谈论dojox/grid,该组件只知道如何消费dojo/data商店。这让您有两个选择:

  • 利用dojo/data/ItemFileWriteStore
  • 使用dojo/store/MemoryWrapped in dojo/data/ObjectStore(它dojo/storedojo/dataAPI 包装 a,以便旧商店的消费者可以使用它)

另一件值得考虑的事情是它dojo/store/Memory不支持直接从 URL 中提取数据,而支持dojo/data/ItemFileWriteStore。如果您打算从另一个 URL 加载数据,您仍然可以使用dojo/store/Memory,但您必须先自己 XHR 数据。

主要感谢一个把xhr的论点

var xhrArgsSolEnv = { url : "BandejaDrawback.htm?action=conSolPrelim", handleAs : "json" };

then i invoke the function

var cargarSolicEnv = dojo.xhrGet(xhrArgsSolEnv);

var xhrArgsSolEnv = { url : "BandejaDrawback.htm?action=conSolPrelim", handleAs : "json" };

and populate the grid

function js_solicitudEnv(data){

            var mydata = new dojo.store.Memory({data : data});
    var store = new dojo.data.ObjectStore({objectStore: mydata});

    var layoutSolEnv = [{ name : "Orden", field : "orden",width : "10%",styles: "text-align: center;" },
                        { name : "Solicitud", field : "numSolicitud",width :"15%" , styles: "text-align: center;" 
                          ,formatter: function(value){return "<a href='#'>"+value+"</a>";}},
                        { name : "Fecha de Registro" ,field: "fecRegistro", width :"25%",styles: "text-align: center;"},
                        { name : "Monto", field: "mtoSolicitado", width :"20%",styles: "text-align: center;"},
                        { name : "Estado", field: "estado", width :"30%",styles: "text-align: center;"}];


    var gridSolicEnv = new dojox.grid.DataGrid({
        store :  store,
        structure : layoutSolEnv,
        style : "width : 800px; height : 150px"
    },"gridSolicEnv");

    gridSolicEnv.startup();


    var btnNuevaSol =  new dijit.form.Button({
        showlabel : true,
        label : "Nueva Solicitud",
        onClick : function(){ 
                    window.location.href = "BandejaDrawback.htm?action=valAccRegistrodeSolicitud";
                  }
    },"btnNuevaSol"); 

    if(data.totalCount >=5){
      btnNuevaSol.set("disabled",true);
    }
}
