I’m still pretty new to rails but I’ve got a lot of the basic stuff  
working.

On one page I have a set of images, and I’d like to make it so that  
clicking them will change a variable I have. Is there a simple method  
for mouse click on object triggers -\> do something? I’m still learning  
all the available commands.

Thanks

Look into link\_to\_function (if it’s all client side) or link\_to\_remote.
