Geocoding String variable

If I make a call like this in JS how to I capture the result IN JS and parse through it and set variables for the Match_addr and X and Y

Jay,

You would use the esriRequest class for this.

Fantastic....had to modify your code a bit, placing the var options= {} inside the click event in order to get it to read my input box contained the address to geocode... just a different workflow as I am not defaulting my address

THANK YOU FOR YOUR INSIGHT AND HELP.....very appreciated.
