遍历对象并更改对象值

Question

I have the following object:

orderSummeryPopin: {
    billingAddress: false, 
    shippingAddress: false,
    changeAddress: false
}

Now I would like to iterate over the object and if the key is equal to the parameter I pass to the function I would like to change the value of that particular key to "true" while setting the others to false .

My function would look kind of like this:

showPopin(selectedPopin) {
    for (var popin in this.orderSummeryPopin) {
        if (selectedPopin === popin) {
            popin = true;
        }
    }
}

I know that

popin = true

doesn't change anything on the object itself. So how can I achieve that?

Answer 1

This should do the trick. It'll iterate over each key/value pair in the original object, and set the value to true if the current key name matches selectedPopin and to false otherwise.

function showPopin(selectedPopin) {
  for(var key in orderSummeryPopin) {
        orderSummeryPopin[key] = selectedPopin === key;
    }
}
