I am trying to utilize and use Dojo on an ASP.Net MVC platform. in Index() view I have
@{
ViewBag.Title = "Home Page";
}
<link rel="stylesheet" href="http://js.arcgis.com/3.18/dijit/themes/nihilo/nihilo.css">
<link rel='stylesheet' href='http://js.arcgis.com/3.18/esri/css/esri.css' />
<script src="http://js.arcgis.com/3.18"></script>
<script src="~/Map/config.js"></script>
<div class="container">
<a role="button" id="lib" class="btn btn-default">Add Libraries</a>
<a role="button" id="sch" class="btn btn-default">Add Schools</a>
<div class="col-md-12" id="map-div"></div>
</div>
in the `config.js` I have
(function () {
'use strict';
var pathRX = new RegExp(/\/[^\/]+$/)
, locationPath = location.pathname.replace(pathRX, '');
require({
async: true,
aliases: [
['text', 'dojo/text']
],
packages: [{
name: 'MapCoctent',
location: locationPath + '../Map/MapCoctent'
}, {
name: 'MapServices',
location: locationPath + '../Map/MapServices'
}, {
name: 'Map',
location: locationPath + '../Map',
main: 'map'
}]
}, ['Map']);
})();
and in the `map.js` I have
require([
'MapCoctent/appcontroller',
'MapServices/mapservices',
'dojo/domReady!'
], function (AppCtrl, mapServices) {
'use strict';
var appCtrl = new AppCtrl({
elem: 'map-div',
mapOptions: {
basemap: 'streets',
center: [-123.141608, 49.245291],
zoom: 12,
autoResize: false
}
});
appCtrl.load();
});
and finally in `mapservices.js` I have
define(["esri/geometry/Geometry",
"esri/geometry/Point",
"esri/graphic",
"esri/symbols/SimpleMarkerSymbol",
"esri/symbols/SimpleFillSymbol",
"esri/Color",
"dojo/on",
"dojo/dom"
], function (Geometry, Point, Graphic, SimpleMarkerSymbol, SimpleFillSymbol, Color, on, dom) {
on(dom.byId("sch"), "click", function () {
var point = new Point(-123.141608, 49.245291);
var markerSymbol = new SimpleMarkerSymbol();
markerSymbol.setStyle(SimpleMarkerSymbol.STYLE_SQUARE);
markerSymbol.setSize(12);
markerSymbol.setColor(new Color([255, 0, 0]));
var pointGraphic = new Graphic(point, markerSymbol);
map.graphics.add(pointGraphic);
});
});
in `appcontroller.js` I have
define([
'dojo/_base/declare',
'esri/map'
], function ( declare, Map) {
return declare(null, {
map: null,
options: {},
constructor: function (options) {
this.options = options;
},
load: function () {
this.map = new Map(this.options.elem, this.options.mapOptions);
}
});
});
but when I click on Add Schools button I am getting this error
Error
TypeError: map.graphics is undefined |
can you please let me know what I am doing wrong and why the map still is undefined while is already instantiated on the page?
Try adding a require for esri/map to your mapservices.js
Thanks Robert but this doesn't help either. besides In that case I need to create another map object that looks like it is unnecessary! am I correct?
Nope, you do not create a new map, you just require the map class so the code knows about the map class.
well I did what you said but still getting same error!
I've had success defining my packages first. Index.cshtml
<script type="text/javascript">
var locationPath = location.pathname;
var dojoConfig = {
packages: [{
name: "main",
location: locationPath + "/js"
}, {
name: "app",
location: locationPath + "/js/app"
}]
};
</script>
<script src="//js.arcgis.com/3.17"></script>
<script src="~/js/Controller.js"></script>
Controller.js
$(document).ready(function () {
require(["main/plugins/bootstrapmap.min"],
function (BootstrapMap) {var map = BootstrapMap.create("mapDiv", {
sliderStyle: "small",
logo: false,
autoResize: false,
scrollWheelZoom: true,
showLabels: true,
basemap: "cosastreets",
zoom: 2
});});
lg21155 is correct. The package definitions need to come before you load the ArcGIS API URL. Lines 6 and 7 in your CSHTML need to be swapped. Also, the package definitions should be assigned to a variable called dojoConfig rather than being inside of a call to require.
