javascript - Dynamically changing cursor/setting cur files -


how can dynamically change style of cursors on div using js or css? because have multiple situations... i've tried code below: 

    div.addeventlistener("mouseover", function(evt) {         if (tool == "bc"){           div.style.cursor = "url(/icons/bc.cur)";         }         if (tool == "pan"){           div.style.cursor = "url(/icons/pan.cur)";         }      }

assuming you're using conditional comments in html5 boilerplate define style (note different syntax newer browser — see mdn docs further information):

div.bc { cursor : url(/icons/bc.cur), auto;  } div.pan { cursor : url(/icons/pan.cur), auto; }  /* style ie<9 */ .lt-ie9 div.bc { cursor : url(/icons/bc.cur); } .lt-ie9 div.pan { cursor : url(/icons/pan.cur); }

and, assuming simplicity div hasn't class applied, change js code so:

div.addeventlistener("mouseover", function(evt) {     this.classname = tool.tolowercase(); }

this approach ensure scalability, since in case have cursor list, javascript doesn't need modified further, add new couple of css rules. furthermore totally keep off css javascript, javascript has better mantainability.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
