Question

以下是我的代码的简化版本。

define ([ 
"dojo/dom",
"dojo/_base/array", 
"dojo/_base/declare",
"dgrid/OnDemandGrid", 
"dgrid/Selection",
"dgrid/Keyboard",
"dijit/form/Button",
"dojo/store/Memory",
"dojo/dom-construct",
"dojo/string",
"esri/layers/FeatureLayer", 
"esri/tasks/query",
"esri/tasks/QueryTask",
"javascript/myUtilities",
"javascript/myCSV",
"javascript/myGrid"
  ], function (  
dom,arrayUtils,declare,Grid,Selection,Keyboard,Button,Memory,domConstruct,dojoString,FeatureLayer,Query,QueryTask, myUtilities, myCSV, myGrid) {  
return {
        initializeParkGrid: function(gridid, gridDiv){
                            //code is here
                            return app.parkGrid;
                            },     
        initializeTrailGrid: function(gridid, gridDiv){
                                //code is here
                            return app.trailGrid;
                            },

        updateParkGrid: function(){     
                                //code is here

                              app.parkGrid.on('.dgrid-row:click', function(event){
                                  initializeTrailGrid();
                              });
                            });
                        }                                   
        };
  });

我想在initializeTrailGrid()中点击一行时调用app.parkGrid函数。当我尝试在编写时运行它时，我收到一个错误，告诉我initializeTrailGrid不是函数。如果我从另一个文件中的initializeTrailGrid()块调用define，则可以正常工作。上面显示的代码位于文件myGrid中，因此我尝试将javascript/myGrid放在定义列表中，并使用myGrid.initializeTrailGrid()来调用它，但这也不起作用。考虑到define块的结构如何，有没有办法做到这一点？

最好创建一个类：

Myclass = function () {
    this.initializeParkGrid = function (gridid, gridDiv) {
        return app.parkGrid;
    }
}

然后，在click事件中，调用方法...不要忘记初始化类：

var myclass = new Myclass();

app.parkGrid.on('.dgrid-row:click', function(event){
   myclass.initializeParkGrid(a, b);
});

从块中的不同函数调用定义块中的javascript函数
