mootools类重载

var MyClass = new Class({
    initialize: function(value) {
        this.value = value;
    },
    
    // 方法重载示例
    process: function() {
        if (typeOf(this.value) === 'string') {
            return this._processString();
        } else if (typeOf(this.value) === 'number') {
            return this._processNumber();
        } else {
            return 'Unsupported type';
        }
    },
    
    _processString: function() {
        return 'Processing string: ' + this.value;
    },
    
    _processNumber: function() {
        return 'Processing number: ' + this.value;
    }
});

// 使用示例
var instance1 = new MyClass('Hello');
console.log(instance1.process()); // 输出: Processing string: Hello

var instance2 = new MyClass(123);
console.log(instance2.process()); // 输出: Processing number: 123
