javascript inherance? with Private vars and methods too -

-

hy need inherent class another.

parent has private var "_data" , private method "_test" , public method "add" child have public method "add", uses private method parent "_test" , private var "_data".

how do this?

var parent = function(){     var _data = {};     var _test = function(){alert('test')};     this.add = function(){alert('add parent')} }  var child = function(){     this.add = function(){// here uses _data , _test parent class         alert('add child')     } }  // inherent child parent // instance child , use add method

and think im miss prototype concept (javascript inheritance)

a simple inheritance:

function createchild(){     child.prototype=new parent()     return new child() }

this way fresh initialization of parent every child.

(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."
