如何在JavaScript对象中定位属性

Question

I have the following problem. I'm sure the solution is rather simple, but I just can't figure it out.

So there is a object which goes like this:

var products = {
    "productType1" : {
        "productCode" : {
            "name" : "Some Name 1",
            "price" : "250"
        },
        "productCode2" : {
            "name" : "Some Name 2",
            "price" : "300"
        },
        "productCode3" : {
            "name" : "Some Name 3",
            "price" : "330"
        }
    }
}

And I try to match a "productCode" property in a "for in" loop with a variable. And then I just try to access the "name" or "price" property but in return I only get "undefined", although I do get match with a "productCode" property.

for(a in products.productType1){
    if(finalCode === a){
        console.log(a.name);
        break;
    }
    else{
        console.log("This is not the property you're looking for");
        continue;
    }

So the question is - how can I access the above mentioned properties in a loop?

Answer 1

a is a string containing the property name. It isn't the value of that property. You need to get the value first.

products.productType1[a].name
