ReferenceError: HomeButton is not defined

BrandonGilhooly

I am learning to code via Javascript Api, very new and a bit stuck.

Pretty simple code, but I don't understand why I am getting the following 2 errors in Firebug:

ReferenceError: HomeButton is not defined
var homebutton = new HomeButton({

"NetworkError: 404 Not Found - http://js.arcgis.com/3.9/js/esri/dijit/Homebutton.js"

Here is my code. Any assistance or critiquing would be much appreciated:

replace home.startup with homebutton.startup. I have adjusted the code that I posted.

Tim,

This is actually giving me an error on ln 64 and the button does not work. I have referenced the online sample and no luck

TypeError: home.startup is not a function

Thank you both !

Ah...I missed that lowercase "b"! Good catch!

TimWitt

Ken,

the issue is that his "esri/dijit/Homebutton" has a lower case "b" in Button.

Here is the full code you need, plus what Ken said.

Hope this helps!

I have also added a HomeButton style, so the button would appear below your zoom.

The code is having a problem with the node "HomeButton" (in red) that is never defined in your markup

    var homebutton = new HomeButton({
       map: map
     }, "HomeButton");



  </script>
</head>
  <body>
       <div id="search"></div>
       <div id="map"></div>
  </body>
</html>

If you look at the HomeButton sample, you'll see that its markup contains a div named "HomeButton" where yours doesn't.

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