Add Dojo Button

BrandonPrice — Fri, 17 Nov 2017 17:10:32 GMT

I would like to add a dojo button using the javascript var mybutton = new button method to the bottom right of a web app inside the map. How do I do that?

Thanks,

Brandon

Brandon,

This is a pretty broad question. Do you understand the use of placeAt and how to use the style do an adsolute positioning?

Hi Robert,

All I know is the placement of a dojo button at the bottom of a splash page I made. Something like: }).placeAt(splashPage1.containerNode);. I was wondering how to do this in the map itself. I am not sure exactly sure what absolute positioning is. I would guess the placement of the button on the map.

Brandon,

Here is a sample for adding a button over the map when your dojo layout panes:

Brandon,

Did my sample help?

Re: Add Dojo Button

BrandonPrice — Mon, 27 Nov 2017 17:49:37 GMT

Hi Robert,

Yes. This is a great sample I will incorporate in the future on other projects. Sorry for the trouble. For this project, which is a storymap: https://caltrans.maps.arcgis.com/apps/MapSeries/index.html?appid=9c9b080c67af4d2db74b663efba971bd (that is the AGOL version; the other is on a non-public facing server), I am still figuring out a basemap toggle solution. I found that my basemap layer on all maps in the story is app.map.getLayersVisibleAtScale()[0]. Which is the Iayer:

https://www.arcgis.com/sharing/rest/content/items/0e0aa048cb9a42de91ae287fc5632fac/resources/styles/root.json

in your sample. I would like a solution that uses the arcgis api 3.22 basemap toggle using a basemaptoggle.on selection change or something like:

baseMapToggle = new BasemapToggle({
map: app.map,
basemap: "myImagery",
toggle: function () {
if (isWorldView) {
isWorldView = false;
// switch to Imagery
app.map.getLayer(app.map.layerIds[1]).setVisibility(false);
app.map.getLayer(app.map.layerIds[0]).setVisibility(true);
} else {
isWorldView = true;
// switch to world view
app.map.getLayer(app.map.layerIds[0]).setVisibility(false);
app.map.getLayer(app.map.layerIds[1]).setVisibility(true);
}
}
}, "BasemapToggle");
baseMapToggle.startup();

that toggles the other layer in your sample. Any examples on turning off layers using something like app.map.getLayer(app.map.layerIds[0]).setVisibility(false); with a basemap toggle?

Sorry for the late response by the way. I was trying ways on getting it to work with no luck and then got interrupted by the holidays.

Brandon,

I am not able to get the basemap toggle dijit to work with your vector layers.

Hi Robert,

No problem. I appreciate the example. I will use the in the future in other apps.
