JS : 객체

 

- 객체 생성하기

var grades = {'a':10, 'b':15, 'c':20};

var grades = {};
grades['a'] = 10;
grades['b'] = 15;
grades['c'] = 20;

var grades = new object();
grades['a'] = 10;
grades['b'] = 15;
grades['c'] = 20;

 

 

- 객체 값 가져오기

grades['a']    // 10
grades.a       // 10

for(key in grades) {
    document.write(key + ':' + grades[key]);
}
