dom is undefined error when trying to upload shapefile

MateenEsfahanian — Tue, 24 Jun 2014 18:23:20 GMT

I have been working on an arcgis project for the last two weeks and I have ran into an issue with my upload shapefile function in my code. I keep getting an dom is undefined error and I don't know what to do.

Here is the code:

<div class="modal fade" id="UpdateShapefileForm" tabindex="-1" role="dialog" aria-    labelledby="Set View" aria-hidden="true">
 <div class="modal-dialog">
  <div class="modal-content">
   <div class="modal-header">
    <form enctype="multipart/form-data" method="post" id="uploadForm">
          <div class="field">
              <label class="file-upload">
                  <span><strong>Add File</strong></span>
                 <input type="file" name="file" id="inFile"/>
              </label>
          </div>
         </form>
        </div>
       </div>
      </div>
     </div>

error happens specifically on this line:

dom.byId('upload-status').innerHTML = '<b>Loading </b>' + name;

I don't see a div with an id of "upload-status" in your HTML.

when I added that line

<div class="modal fade" id="UpdateShapefileForm" tabindex="-1" role="dialog" aria-labelledby="Set View" aria-hidden="true">
<div class="modal-dialog">
  <div class="modal-content">
    <div class="modal-header">
      <div id="upload-status">
        <form enctype="multipart/form-data" method="post" id="uploadForm">
                          <div class="field">
                  <label class="file-upload">
                      <span><strong>Add File</strong></span>
                      <input type="file" name="file" id="inFile"/>
                  </label>
              </div>
            </div>
               </form>
              </div>
              </div>
              </div>
              </div>

I still get the dom error

It looks like your generateFeatureCollection() function is outside of your require scope so dom is undefined, as the error states.

From our very first tutorial:

The global require() function (provided by Dojo) is used to load modules. Esri's JavaScript API is built on top of Dojo and relies on Dojo for its module system and other features like vector graphics and localization as well as a way to abstract away browser differences. For more information on the relationship between Dojo and the JavaScript API, see Working with Dojo and Why Dojo.
