catch no result in custom geocoder

MarcusTownsend — Thu, 08 May 2014 18:48:29 GMT

I'm new to the Javascript API but not new to Javascript, but maybe rusty admittedly.

I'm having a hard time figuring out how to catch when a custom geocoder does not return an address for entered search.

Example coded below.

Search for "hay" and the display div is populated with the returned name "Hay street". if you search for "super street" , which returns nothing. I would want it display "no information"

Anyone able to guide me in the right direction.

Hi Marcus,

You can accomplish this by using the find-results event. Ex:

geocoder.on('find-results', showLocation)  function showLocation(evt) {   if(evt.results.results.length > 0){     $('#display').append(evt.results.results[0].name);   }   else{     $('#display').append("No Information");   } }

Thanks for the response. I thought that 'find-results' would only happen when results where where returned based off the api summery.

Worked like charm in my app.
