  1. PODojo AMD module changes reference of "this"
    text
    copied!<p>I'm really confused as to some behavior I'm seeing in trying to learn the AMD style of Dojo. When I instantiate my module/object, "this" refers to the object in my constructor. I make a call to an internal function, and "this" inside that internal function refers to the Window object. So when I get to this.attachMapEventHandlers I get a "Object [object global] has no method 'attachMapEventHandlers'" error. What am I doing wrong? UPDATE: I found lang.hitch, which seems to indicate that the async nature is what's tripping me up, but I'm confused on how to implement a solution.</p> <p>my script inside index.html:</p> <pre><code>require(["javascript/layout", "dijit/layout/ContentPane", "dijit/layout/BorderContainer", "dijit/layout/AccordionContainer", "dojo/dom", "dojo/dom-attr", "dijit/Toolbar", "dijit/form/Button", "dijit/Dialog","dijit/ProgressBar", "dojo/domReady!"], function (layout, dom, domAttr) { mapControl = new layout(); </code></pre> <p>layout.js:</p> <pre><code>define(["dojo/_base/declare"], function(declare) { return declare(null, { action:"pan", activeMeasureTool:"", aerialLayer:"", legendLayers:"", loadedServices:"", popup:"", resizeId:0, constructor: function() { this.init(); }, init: function() { require(["esri/map", "esri/config", "esri/SpatialReference", "esri/geometry/Extent"], function(Map, config, SpatialReference, Extent) { //custom map requires a proxy to function properly. esri.config.defaults.io.proxyUrl = "../sdc_devdata/proxy.php"; var spatRef = new SpatialReference(2276); var startExtent = new Extent(2481416.32087491, 6963246.42495962, 2501196.36936991, 6980267.92469462, spatRef); var appFullExtent = new Extent(2396699.46935379, 6872369.60195443, 2607745.94404633, 7107335.22319087, spatRef); map = new Map("map", {extent: startExtent, isZoomSlider:true, logo:false, sliderStyle:"large"}); this.attachMapEventHandlers(); this.createLayers(); this.handleLayerVisibilityChange(); }); }, </code></pre>
