Javascript Object not working with Native javascript methods like match(), replace etc

Question

Here is the issue:

I go this Code:

var str = {"Acc":10 , "adm_data":"Denied"};

When I do something like:

console.log(str.Acc.match(/[0-9]+/g)) // To Get the Integer Value from the "Acc" key

Firebug Screams:

TypeError: str.Acc.match is not a function

console.log(str.Acc.match(/[0-9]+/g));

See Image:

enter image description here

I always do something like:

var str = "Hello _10";

console.log(str.match(/[0-9]+/g)) // This Works

Why is the Object thingi not working?

PLEASE NOTE:

As mentioned by @Fabrício Matté. The issue was that I was trying to pass an integer Value to the .match method which does not belong to integers. The solution was to do what @kundan Karn Suggested. Something like: str.Acc.toString().match(/[0-9]+/g)// Converting it first to string then match. It worked!

Tried your code and it works fine :) I used nodeJS to test it though — Rami, Oct 31 '13 at 08:11
@Fabricio Matte ... Can you Eplain what You mean?.. @surrender's suggestion worked well but when I try Something like: `var str = {"Acc":10,"adm_data":"Denied"};` _Notice the **Raw Integer** value... This gives the Same error back why? — Universal Grasp, Oct 31 '13 at 08:18
@UniversalGrasp What I mean is that it is impossible to reproduce the issue with the code in the question. Now that you've shown a number value, the error happens because Numbers do not have inherit `match` which is a string method. Kundan and Kristof's answers should solve the issue. — Fabrício Matté, Oct 31 '13 at 08:21

match function works with string. So convert it to string first

str.Acc.toString().match(/[0-9]+/g)

It works just fine: http://jsfiddle.net/nKHLy/

but in order to get rid of the error you might want to try:

var str = {"Acc":"Hello_10" , "adm_data":"Denied"};
console.log(String(str.Acc).match(/[0-9]+/g));

or

var str = {"Acc":"Hello_10" , "adm_data":"Denied"};
console.log(str.Acc.toString().match(/[0-9]+/g));

To know the difference between the 2 options, check: What's the difference between String(value) vs value.toString()
