javascript - Find and replace occurrence of string in whole html itself -

-

assume 

<html>   <head>....</head> <body>  .  .  // occurrences here  .   </body> </html>

i do

$(function() {     $('html').html() = $('html').html().replace(/strtofind/g,'somethingelse'); });

in head, does't work. how find , replace occurrence of string in html document (not store in variable)?
thanks

.html() function returns html, can't assign it. if want change html of object in jquery, put new html parameter function:

$('html').html($('html').html().replace(/strtofind/g,'somethingelse'));

haskell - Using Monad/ST for non-concurrent message passing in a mutable graph -

-
i trying work out data structure following situation. graph structure i plan have graph of nodes un-weighted, directed edges: graph = [node] each node has: some tbd internal (persistent) state a queue of incoming messages a type of message can send determined function accepts current node state (with possibility of failure) a list of edges node { nodestate :: nodestate, inbox :: queue nodemessage, nodemessage :: (nodestate -> maybe nodemessage), connections::[nodeedge] } each edge intermediary step capturing pending messages target node nodeedge { pendingmessage:: maybe nodemessage, targetnode :: node } message passing the message passing happens in phases , not-conccurent (though queues may processed in parallel reduce computation time). phase 1: check inbox of every node, processing messages , updating nodestate if relevant. phase 2: have every node run nodemessage , if results in just nodemessage , send nodemessage every connection ( [nodeedge] ) ...
