jquery - Javascript Memory Usage -

-

in following code: 

$(document).ready(function() {     var content = "";     (var = 0; < 1000; i++) {         content += "<div>testing...</div>";     }     $("#load").click(function() {         $("#mydiv").empty();         $("#mydiv").append(content);         return false;     }); });

load simple link , mydiv simple div. in each major browser tested in, when click on link multiple times, see memory usage go in task manager. in ie, goes each time , stays up. in ff, goes each time, once in while comes down (i think means memory being reclaimed or garbage collected - sign). in chrome, goes each time , stays up.

first, code cleaning dom correctly? if so, why memory usage increase every click?

note: tried make example simple possible, similar problem having in app.

wrap around div tag. immensely , use native innerhtml (its faster).

$(document).ready(function() {      var content = "";      (var = 0; < 1000; i++) {          content += "<div>testing...</div>";      }      $("#load").click(function() {          document.getelementbyid('mydiv').innerhtml = ('<div>'+content+'</div>');          return false;      });  });

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() .

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
