Need help activating buffer query with button

Question

I have tried a few ways to activate my buffer query with a button, but (being a newbie), I have failed. The buffer I have set up works, but since I'm also going to have an identify button on the page, I need to have the user activate the buffer query with a button as well. Otherwise the buffer will run everytime the user clicks to identify a feature. I know how to toggle an identify task off and on, but I can't figure out how to control the buffer. Anyhelp would be appreciated. Here's the code QueryTask with query geometry from another task Zoom to area and click on map to select protected areas within the buffered circle.
Buffer distance (in miles):

The best way to do this is to create a delegate to handle identify and buffer events. Here is how you do it: //globle variable (could be a boolean, int or string): var actionMode ="identify"; //default ...... dojo.connect(map, "onClick", doActionAccordingly); ...... function doActionAccordingly(evt) { switch (actionMode) { case "identify": .... identify go here break; case "bufferQuery": .... buffer query goes here // remember reset actionMode ="identify" after finish buffer query break; ........ } } function bufferBtn_onclick() { //set action mode to buffer actionMode ="bufferQuery"; } Hope it will help
