gets the same attribute name and value, for reference only:

function getCommonObj(arr,key,val){//arrkeyval
        var valArr = []//
        for(var i=0; i< arr.length; iPP){
            if(arr[i][key] == val){
                valArr.push(arr[i])//
        }
        }
        if(valArr.length>=2){
            return valArr
        }
}
