动态创建原型并推送到数组

Question

I'm trying to dynamically create objects of 'test' that are pushed to an array, I know the code below doesn't work, it's for reference to help solve my problem:

var test = (function(){
    var blah;

    test.prototype.getNumber=function(){
        return blah;
    }
    test.prototype.setNumber=function(val){
        blah=val;
    }
});

var array=(function(){
    var array[];

    array.prototype.get=function(index){
        return array[index];
    }
    array.prototype.set=function(obj){
        array.push(obj);
    }

});

var objArray=new array();

for(var i=0;i<6;i++){
    objArray.set({
        setNumber(5);
    }=new test());
}

Answer 1

The first step would be to create your constructor functions properly. It seems you want to simulate private properties by using local variables and closures. In that case you have to assign the methods to the instance itself, not the prototype:

this.setNumber = function(){
    return blah;
};
// instead of
// test.prototype.setNumber = ...;

The same for array .

To add an instance, all you have to do is create a new test instance and call its setNumber method:

for(var i=0;i<6;i++){
    var obj = new test();
    obj.setNumber(5);
    objArray.set(obj);
}

Note: Constructor function names usually start with a capital letter.
