如何從jquery/javascript中統計一個數組的鍵名？

Question

傢伙我有在json format.It一直encoded數組看起來象下面這樣： -

{"result":[{"pid":"24","uf":"hancy061","ot":"sanjit061","dn":"November 6,2015 at 02:18pm","view":"0","nu":"hancy061"},{"pid":"23","uf":"hari061","ot":"sanjit061","dn":"November 6,2015 at 01:09pm","view":"0","nu":"hari061"}]} 

現在

總之，我的問題是，我可以算的view總數從jQuery的/ JavaScript的我想要什麼？來計算view並將該號碼存儲在var。請注意，這可能不算什麼大事。有沒有什麼辦法可以從jquery/javascript中計算出view？幫助需要的人。

您可以使用RegExp和.match

var data = JSON.stringify({ 
 
    "result": [{ 
 
     "pid": "24", 
 
     "uf": "hancy061", 
 
     "ot": "sanjit061", 
 
     "dn": "November 6,2015 at 02:18pm", 
 
     "view": "0", 
 
     "nu": "hancy061" 
 
    }, { 
 
     "pid": "23", 
 
     "uf": "hari061", 
 
     "ot": "sanjit061", 
 
     "dn": "November 6,2015 at 01:09pm", 
 
     "view": "0", 
 
     "nu": "hari061" 
 
    }] 
 
}); 
 

 
var count = (data.match(/view/g) || []).length; 
 
console.log(count);
