Question

I broke the google map on this page, and it is giving me an error:

placeHikesMarkers is not defined

What is the best way to debug JS in this case?

Answer 1

Firebug or Chrome Console. You have this in Firebug:

syntax error
http://www.comehike.com/hikes/search_hikes.php?all=yes&when=f&redirect=yes
Line 577

var lng = ;

And:

placeHikesMarkers is not defined
http://www.comehike.com/hikes/search_hikes.php?all=yes&when=f&redirect=yes
Line 1

This particular issue is because your script stops at the first, then calls the second, which is not defined because the error was inside the function:

var placeHikesMarkers = function(){

    var lat = -122;
    var lng = ;
