[Javascript] JQuery @(at) 처리 문제.

$('#@id').removeClass('new').addClass('old');

여기서 @ 때문에 jquery 내부에서 오류가 발생을 합니다.

이럴 경우 DOM 을 직접 컨트롤 해주셔서 해결 하시면 됩니다.

var policyId = 'result' + policyName;

var el = document.getElementById(policyId);

el.classList.remove('new');

el.classList.add('old');

Chapter 19 Object-Oriented Programming in Perl

CONTENTS

Listing 19.1. The initial Cocoa.pm package. package Cocoa;

sub new {

    my $this = {};  # Create an anonymous hash, and #self points to it.

    bless $this;       # Connect the hash to the package Cocoa.

    return $this;     # Return the reference to the hash.

    }

Listing 19.2. Creating the constructor.

1  #!/usr/bin/perl

2  push (@INC,'pwd');

3  use Cocoa;

4  $cup = new Cocoa;
sub new {

        my $class = shift;        # Get the request class name

        my $this = {};

        bless $this, $class        # Use class name to bless() reference

        $this->doInitialization();

        return $this;

    }

더 자세한 건 사이트 들어가서 보삼.. ㅎㅎ

perl 로 class 만드는 것 중 기본은.. package 를 만드는 것이고 pacakge 의 끝은 1; 로 끝나야 한다는거.. ㅎㅎ

•Class & Inheritance

사용자 삽입 이미지

•Class & Inheritance

–-Prototypal Inheritance

var oldObject = {

firstMethod: function () { alert("first"); },

secondMethod: function () { alert("second"); }

};

var newObject = new Object(oldObject);

newObject.thirdMethod = function () { alert("third"); };

var myDoppelganger = new Object(newObject);

myDoppelganger.firstMethod(); // or

myDoppelganer[“firstMethod”]();

var obj1 = function () {

this.title = "obj1";

}

var obj2 = function () {}

obj2.prototype = new obj1;

var obj2Class = new obj2();

alert(obj2Class.title);

obj1 = {

title:"obj1_"

}

obj2 = new Object(obj1);

alert(obj2.title);

–-Method apply (Member variable)

§Function.apply(thisArg[, argArray])

–function Car(make, model, year) {

– this.make = make;

– this.model = model;

– this.year = year;

–}

–

–function RentalCar(carNo, make, model, year) {

– this.carNo = carNo;

– Car.apply(this, new Array(make, model, year));

–}

–

–myCar = new RentalCar(2134,"Ford","Mustang",1998);

–document.write("Your car is a " + myCar.year + " " + myCar.make + " " + myCar.model + ".");

–-Method apply (Member function)

§function TopClass (name, value) {

§ this.name = name;

§ this.value = value;

§ this.getAlertData = function () {

§ alert(this.name);

§ alert(this.value);

§ }

§}

§function SubClass (name, value, dept) {

§ this.dept = dept;

§ TopClass.apply(this, arguments);

§ this.getView = function () {

§ this.getAlertData();

§ }

§}

§//SubClass.prototype = new TopClass();

§var objSubClass = new SubClass("상위클래스","super","community");

§objSubClass.getView();

–-Method call

§Function.call(thisArg[, arg1[, arg2[, ...]]])

–function car(make, model, year) {

– this.make = make, this.model = model, this.year = year;

–}

–

–function hireCar(carNo, make, model, year) {

– this.carNo = carNo, car.call(this, make, model, year);

–}

•-Prototype

–Profiler = function () {..}

–Profiler.prototype.name = function () {..}

•-Namespace

–YAHOO = {};

•-new operator

–function object(o) {

– function F() {};

– F.prototype = o;

– return new F();

–}

–classA = new Profiler(); or classA = object(Profiler);

-Encapsulate (Parasitic)

YAHOO = {};

YAHOO.Trivia = function () {

var privateVar = "showPoser";

function privateNextPoser() {

alert("getNextPoser");

}

return {

getNextPoser: function (cat, diff) {

privateNextPoser();

},

showPoser: function () {

alert(privateVar);

}

};

} ();

function getFunc() {

var oObj = YAHOO.Trivia;

oObj.getNextPoser();

}

YAHOO = {};

YAHOO.Trivia = function () {

var privateVar = "showPoser";

function privateNextPoser() {

alert("getNextPoser");

}

return {

getNextPoser: function (cat, diff) {

privateNextPoser();

},

showPoser: function () {

alert(privateVar);

}

};

function getFunc() {

var oObj = new YAHOO.Trivia();

oObj.getNextPoser();

}

-Singletons

var singleton = function () {

var privateVariable;

function privateFunction(x) {

...privateVariable...

}

return {

firstMethod: function (a, b) {

...privateVariable...

},

secondMethod: function (c) {

...privateFunction()...

}

};

}();
