Question

大家好，我对Kendo UI Grid组件感到疯狂。我使用dataSource.transport.read在GET中加载JSON Jersey服务。代码是这样的：

 var args = new Object();
   args.procomfilter = "058091_054051";
   args.userGrid = "false";
   args.take = "20";
   args.skip = "0";
   args.row = "Comuni";

var _dataSourceGrid = new kendo.data.DataSource({
        pageSize: 20,
        serverPaging: true,
        serverSorting: true,
        serverFiltering: true,
        transport: {
            read:{
              type: "GET",
              url: "services/viewData/filtracomuni" ,
              data: JSON.stringify(args),  
              cache: false } } ....

var _grid = $(gridId).kendoGrid({
        dataSource: _dataSourceGrid,
        columnMenuInit: function(e) {
            var item = e.container.find(".k-columns-item");
            item.prev(".k-separator").remove();
            item.remove();
        },
        width: "100%",
        height: "100%",
        toolbar: kendo.template($(gridId+"Template").html()),
        resizable: true,
        //sortable: true,
        columnMenu: !userGrid,

...

在firebug上我发现args完全被忽略了

但如果我直接打电话：

$(_gridId).kendoGrid({
    dataSource: {
        transport: {
             read: { 
                         type: "POST",
                         url: "services/viewData/filtracomuni", 
                          data: JSON.stringify(args) 
                    }

        }
    }
});

它有效，为什么？非常感谢

当您实例化数据源时，您的JSON.stringify(data)会立即执行，此时您的数据尚未就绪。要解决此问题，您需要将stringify包装在函数中：

var _dataSourceGrid = new kendo.data.DataSource({
        transport: {
            read:{
              type: "GET",
              url: "services/viewData/filtracomuni" ,
              data: function() { return JSON.stringify(args); },
              dataType : "json", 
              cache: false
            } }

...
