Custom Zoom not working

SethCrotchett — Thu, 11 Apr 2013 18:14:37 GMT

I am trying to implement custom zoom in and zoom out buttons. It doesn't seem to be working. I was looking at one of the examples. http://help.arcgis.com/en/webapi/javascript/arcgis/jssamples/toolbar_navigation.html.

The custom zoom in and zoom out buttons in the example dont work either so this makes me believe there is a bug.

Can anyone help me on this? Is this a bug or am i doing something wrong?

The custom zoom in and zoom out buttons work fine for me in that example. I am accessing from Firefox 19. What browser are you using?

Could you post some code where the problem is occurring?

I have tried the sample on multiple browsers. Chrome and Firefox on Mac.

Chrome Version: 26.0.1410.65
Firefox: 19.0.2

Are you properly dragging the tool to select the extent you wish to zoom in / zoom out on?
Do you receive any errors when attempting to zoom with either tool?

Ok, i was thinking the zoom in button would just zoom in one level. I didn't know you had to draw on the map for it to zoom. Is there a way to have a custom zoom in button do what i was expecting? So you press the zoom in button and it zooms in one level and so on.

You could create a zoom in button and zoom out button that call the following functions when clicked:

function zoomInLevel() {
map.setLevel(map.getLevel() +1);
}

function zoomOutLevel() {
map.setLevel(map.getLevel() -1);
}

This is what the + and �?? buttons in the top left corner of the map do.
