Question

如何将实例化对象的属性作为JavaScript函数中的参数传递。我想这样做，以便我被迫总是使用对象的相同属性。

我该怎么做？

//object
var house = {
    bed:"",
    chair:"",
    tv,""

};

//function
var doThis = function(OBJ){

    //pass this OBJ to something
    alert(OBJ.bed);
    alert(OBJ.chair);
    alert(OBJ.tv);


};


//call function
doThis({new house.bed = "a", new house.chair="c", new house.tv = "f"});

doThis({new house.bed = "dd", new house.chair="gg", new house.tv = "jjjh"});

doThis({new house.bed = "ff", new house.chair="hh", new house.tv = "hhh"});

doThis({new house.bed = "gg", new house.chair="jjj", new house.tv = "hh"});

Answer 1

不太了解这个问题，但是你的代码包含语法错误，函数的调用应该是这样的：

doThis({bed: "a", chair: "c", house: "f"});

Answer 2

你的代码离javascript很远，但你可以这样做：

function House(bed, chair, tv) {
    this.bed = bed;
    this.chair = chair;
    this.tv = tv;
}
doThis(new House("a", "c", "f"));
doThis(new House("dd", "gg", "asd"));

Answer 3

像Esailija说的那样，除了doThis没有定义，所以使用这样的东西：

function House(bed,chair,tv){
    var obj = {};
    obj.bed = (bed) ? bed : "";
    obj.chair = (chair) ? chair : "";
    obj.tv = (tv) ? tv : "";
    return obj;
  }

  var myHouse = new House('water bed');
