对象中的数组去重去空

var obj = {
    "W":[
    "1111",
    "",
    "11111",
    "1111",
    "",
    "11111",
        ],
    "s":[
    "222",
    "",
    "2222",
    "2"
    ]
    }
    var newArr=[];
    for(var key in obj) {
        keys.push(key);
        values.push(obj[key]); //取得value    
        for(var i=0;i<obj[key].length;i++){
            console.log(obj[key][i])
            if(newArr.indexOf(obj[key][i])==-1  && obj[key][i]!="" && obj[key][i]!=undefined){
                  newArr.push(obj[key][i]);
            }
        }
    }
    console.log(newArr)
