您的問(wèn)題不清楚，但我假設(shè)您需要其值為對(duì)象且包含“語(yǔ)言”鍵的鍵，并且“語(yǔ)言”鍵的值應(yīng)為“BENGALI”。


//In the case of multiple keys

var obj = {"bn_IN":{"status":"SUCCESS","language":"BENGALI","message":"Translated successfully"},"sq_AL":{"status":"SUCCESS","language":"ALBANIAN","message":"Translated successfully"},"af_ZA":{"status":"SUCCESS","language":"AFRIKAANS","message":"Translated successfully"},"da_DK":

        {"status":"SUCCESS","language":"DENMARK_DANISH","message":"Translated successfully"},

        "ar_DZ":{"status":"SUCCESS","language":"ARABIC","message":"Translated successfully"}}


var keys=[]


for(key in obj){

     if(obj[key].language==="BENGALI") keys.push(key)

}


// In case if you know that key is unique


var obj = {"bn_IN":

        {"status":"SUCCESS","language":"BENGALI","message":"Translated successfully"},"sq_AL":

        {"status":"SUCCESS","language":"ALBANIAN","message":"Translated successfully"},"af_ZA":

        {"status":"SUCCESS","language":"AFRIKAANS","message":"Translated successfully"},"da_DK":

        {"status":"SUCCESS","language":"DENMARK_DANISH","message":"Translated successfully"},

        "ar_DZ":{"status":"SUCCESS","language":"ARABIC","message":"Translated successfully"}}


var key="";


for(key in obj){if(obj[key].language==="BENGALI") key=key}
