Solved! Go to Solution.
Try this:
Add value as property:
[HTML]<input id="toolBuffer" data-dojo-type="dijit/form/Button" data-dojo-props="iconClass:'findNear', showLabel: false, value: 'buff'"></button>[/HTML]
Use .get('value') to get the value:dom.byId('toolBuffer').get('value');
dijit.byId('toolBuffer').get('value');
Sorry...use dijit.byId because it's a widget.dijit.byId('toolBuffer').get('value');
