I try to create a simple javascript external file.  I put all the require & function in one js file, it works. But how do you create another external js file for map function.

<!DOCTYPE html>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"/>
    <title>Simple Map</title>
    <link rel="stylesheet" href="http://js.arcgis.com/3.10/js/esri/css/esri.css">
    <link rel="stylesheet" href="css/layout.css">
    <script src="http://js.arcgis.com/3.10/"></script>
    <script type="text/javascript" src="script/init.js"></script>
  </head>

  <body>
    <div id="map"></div>
  </body>
</html>

---------------------------

layout.css

-------------------------------

      html, body, #map {

        height: 100%;

        width: 100%;

        margin: 0;

        padding: 0;

      }

      body {

        background-color: #FFF;

        overflow: hidden;

        font-family: "Trebuchet MS";

      }

-----------------

init.js

---------------

      var map;

      require(["esri/map", "dojo/domReady!"],function(Map) {
  map = new Map("map", {
          basemap: "topo",
          center: [-122.45, 37.75], // longitude, latitude
          zoom: 13
     });
        });

Thank you.

If you put it in an external file you will not have access to the libraries or variables (map) in your init.js because of how Require.js works. The require(); is wrapping all the libraries and files in to a big function. Everything you do with them needs to be in the function. Maybe look at require.js examples for how to do this.

Assuming you've declared variables representing your map related objects as global, could you just drop another require() structure in the second "external file" and reference any dojo/dijit items needed for that JS file?
