how to access javaScript Number type property

Question

In javaScript Object.

var person = {
  name: "bengen",
  age: 27,
  5: true
}

How can I access the property 5, please?

-_-

Also have a look at some introductory material: https://developer.mozilla.org/en/JavaScript/Guide/Working_with_Objects — Felix Kling, Jul 12 '12 at 15:46

Try using []. For example, person[5] or person["5"]

Just use the access via []:

alert( person[ 5 ] );

A JavaScript object's properties can be accessed by using . or []. The latter is especially useful for numeric keys or in cases, when you have a key identifier stored in another variable.

Thank you! person[5] , person['5'] , person["5"] all can work. – codesve Jul 14 '12 at 06:38

Just use the square bracket accessor rather than the dot:

if(person[5]){
    // if the value is true, do something
}

From what I remember, this should work: person["5"]
