javascript - Altering firebugx.js to Accommodate IE Developer Tools -

-

the firebugx.js file (shown below) checks both !window.console , !console.firebug, correctly detects if firebug installed. however, check not accommodate native console object in ie developer tools -- overwrites ie console object.

for example, if include firebugx.js code, following exception not appear in ie console (it swallowed):

  function foo() {     try {       throw "exception!!!";     }     catch (e) {       console.error(e);     }   }

question: best approach accommodating ie developer debugger? maybe obvious answer comment out firebugx.js check when debugging in ie. there other approaches?

reference:

firebugx.js

if (!window.console || !console.firebug) {     var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml",     "group", "groupend", "time", "timeend", "count", "trace", "profile", "profileend"];      window.console = {};     (var = 0; < names.length; ++i)         window.console[names[i]] = function() {} }

i suppose following modification firebugx.js solve problem. redefine window.console if not exist , optionally define missing functions on window.console. hesitant alter firebugx.js, can't see downside this. it's easiest way switch between firefox , ie debuggers.

firebugxcustom.js

if (!window.console) {   window.console = {}; } if (!window.console.firebug) {   var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml",     "group", "groupend", "time", "timeend", "count", "trace", "profile", "profileend"];    (var = 0; < names.length; ++i) {     if (!window.console[names[i]]) {       window.console[names[i]] = function () { }     }   }  }

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
