New to scripting - Need help with a basic script with functions

[SuzanneRoussie]

Hi,

I am in the process of putting together a basic map by learning off the tutorials and examples found on the JavaScript examples site and I am trying to use a home button, legend, and scale on the same map.  I had the home button and scale working but when I added the script for the legend it stopped working.  I was wondering if there was a limit on how many functions could be called the way I have it set up or if I am missing something else. I am sure there is a different way to do this but since I have never written anything in JavaScript before I thought this was the best way to learn. I have enclosed the text file of my code.

thanks,
Sue

You have a typo

"esri/map", "esri/layers/FeatureLayer", "esri/dijit/Legend",       "esri/digit/Scalebar","esri/dijit/HomeButton",       "dojo/_base/array", "dojo/parser",       "dijit/layout/BorderContainer", "dijit/layout/ContentPane",        "dijit/layout/AccordionContainer", "dojo/domReady!"

That should be  "esri/dijit/Scalebar"

You are also missing a '{' in the style tag for the #map DIV.  Also, if you want the legend to display the layers, you will need to change your extent to where they are visible.  Ex:

map = new Map("map", {
        basemap:"streets",
        center: [-96.509, 38.367],
        zoom: 14
      });

Would this file just need to be added to a server that has IIS in the following location:

\\ServerName\c$\inetpub\wwwroot

in order to have a simple working web application?

Exactly, just like the Flex application.

Thanks, the typo and missing { fixed it.  I have the extent set at 7 so the state of NY appears as a whole for now and the layers are triggered when you zoom in.  I have other layers that need to go on that will be visible at that level, just wanted to get the basics working for now.  It's a slow process when you are learning.  Appreciate the help.

Question in regards to this sample application.

I added my own mapservice layer and it gets added to the map and the legend.

Why don't the ESRI mapservices get added to the legend?  I don't see a place in the text file where they are being excluded from the legend.

The 'layerInfos' option controls this.  See the help here.

Specify a subset of the layers in the map to display in the legend. If not set all layers in the map will display in the legend.
