Calling Rails action from Javascript -

i have link_to in calls update action in controller:

<%= link_to((image_tag("lock_closed.svg", :class => "edit")), :controller => "sections", :action => "update",:id => section.id, :remote => true) %>

---

but call update action through javascript ordinary image tag.

so like:

<%= image_tag("lock_closed.svg", :class => "edit")%>

and:

$(".edit").click(function(){     if ($(this).hasclass("update")){     // call update action     } else {     //do else      }; }) 

---

is possible call action way? i've been finding bit on using get & post or ajax methods i'm not sure how utilise them target specific controller & action.

send ajax call

$(".edit").click(function(){     if ($(this).hasclass("update")){          $.ajax({       type: "put",       url: "/sections/<%= section.id %>"     });   } else {     //do else    };  })
