I am using Drupal 7 and the Google Map Field module. When I click on the Insert Map button, the Firebug console shows this:
$(...).propis not a function
It seems like I need
jQuery.noConflict(), but why is this happening?
Because Drupal ships with jQuery 1.4 and
prop() was added in 1.6.
You could mess about with a second version of jQuery and
noConflict, or you can just install the jQuery Update module and let it handle things for you.
If that won't work (e.g. it produces other conflicts with existing scripts), try jQuery Multi instead.
