Rendering google map using gmaps4rails through Ajax

问题

I want to render the map only on demand(to minimize the loading time), means some link like 'Show Map' should render the map in a specified div. what should i do?

回答1:

Simply use the 'to_gmaps4rails' method described here: https://github.com/apneadiving/Google-Maps-for-Rails/wiki/Methods

Basically, do:

<%=raw assets_hash.to_gmaps4rails(true) %>

This will render only the js necessary to display your assets.

So include gmaps4rails.js and .css (if necessary), and the div to host the map.
