var obj1 = {
name: 'shaanxi',
get nameGet() {
return this.name + 'a';
},
set nameSet(name) {
this.name = name;
}
};
console.info(obj1.nameGet); //shaanxia
obj1.nameSet = 'set by set keywords';
console.info(obj1.nameGet); //set by set keywordsa
第一种方式, 直接在对象内设置。 如代码所示。
var obj2 = {
name: 'shaanxi'
};
obj2.__defineGetter__('nameGet', function() {
return this.name;
});
obj2.__defineSetter__('nameSet', function(
name) {
this.name = name;
});
var ref1 = obj2.__lookupGetter__('nameGet');
var ref2 = obj2.__lookupSetter__('nameSet');
console.info(obj2.nameGet); //shaanxi
obj2.nameSet = 'set by __defineSetter__';
console.info(obj2.nameGet); //set by __defineSetter__
第二种方式: 使用原型方法进行设置
var obj3 = {
name: "shaanxi"
};
Object.defineProperties(obj3, {
nameGet: {
value: function() {
return this.name;
}
},
nameSet: {
value: function(name) {
this.name = name;
}
}
});
console.info(obj3.nameGet()); //shaanxi
obj3.nameSet('set by Object.defineProperty');
console.info(obj3.nameGet()); //set by Object.defineProperty
第三种方式: 使用Object.defineProperty() 和Object.defineProperties() 进行设置
