Using jQuery

Description

This sample shows how to use the jQuery JavaScript framework with the ArcGIS JavaScript API. jQuery is a JavaScript library designed to simplify Web development. Since this application uses the jQuery framework instead of Dojo, this sample uses the compact build of the ArcGIS JavaScript API, which does not include things like Dojo widgets.

When building applications with frameworks other than Dojo, you still need to use dojo to connect to map events. In this snippet, we connect to the map's

onLoad
event and then call
.ready()
.The
.ready()
method is automatically called when the DOM is fully loaded.

require(["dojo/on", "esri/map"], function (on, Map) {map = new Map("map", {basemap: "gray",center: [2.352, 48.87],zoom: 12,slider: false});on(map, "load", function (){console.log("Map load event");// Hook up jQuery$(document).ready(jQueryReady);});});
