route can't display in web

daihere — Thu, 06 Aug 2015 07:58:15 GMT

Hi, all:

Now,Im studying a function about shortest route and I encounter a problem.

I released by arcmap successful network analyze service.

When I try to generate any route, the route is not show in the graphic layer.

When the code is debug to see where is the error, it does't show any problem, and looks all ok.

Can someone give me and advice on where the problem can be???

Here is the js code:

var editToolbar;

var currentLocation

require(["esri/map", "esri/geometry/Point", "esri/layers/ArcGISDynamicMapServiceLayer", "esri/toolbars/draw", "esri/toolbars/edit",

"esri/symbols/SimpleMarkerSymbol","esri/symbols/SimpleLineSymbol", "esri/symbols/SimpleFillSymbol",

"esri/symbols/PictureMarkerSymbol", "esri/graphic", "esri/geometry/jsonUtils", "esri/tasks/RouteTask", "esri/tasks/FeatureSet",

"esri/tasks/RouteParameters", "esri/Color", "dojo/parser", "dijit/Menu",

"dijit/MenuItem", "dijit/MenuSeparator", "dijit/form/Button",

"dijit/layout/BorderContainer", "dijit/layout/ContentPane", "dojo/domReady!"],

function (
