JavaScript對象不是本地JavaScript metods像匹配（）工作，更換等

Question

這裏是問題：

我去這個代碼：

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

當我做這樣的事情：

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

螢火蟲尖叫：

TypeError: str.Acc.match is not a function

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

見圖片：

我總是做這樣的事情：

var str = "Hello _10"; 

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

爲什麼Object一句話是不工作？

請幫忙！

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)// Coverting it first to string then match . It Worked!

Answer 1

匹配功能可與字符串。所以它轉換成字符串第一

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

Answer 2

它工作得很好：http://jsfiddle.net/nKHLy/

但爲了擺脫錯誤的，你可能會想嘗試：

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

或

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