javascript - 为什么我不能过滤我的 javascript/jquery 对象

Question

我有一个如下所示的 JavaScript 对象数组:

[
{"fname":"tim", "lname":"thompson", "user_id": "2", "route_id": "3", "route_day": "WED"},
{"fname":"john", "lname":"wilson", "user_id": "3", "route_id": "3", "route_day": "WED"},
{"fname":"george", "lname":"lane", "user_id": "5", "route_id": "2", "route_day": "MON"}
]

我尝试使用过滤功能过滤掉结果

function filterCustomerData(route,day) {

    var jsonCustData = JSON.parse(localStorage.getItem("db")); 

    console.dir(jsonCustData); // object array with 300+ objects
    console.log( "route is: " + route + " day is: " + day);// route is: 3 day is: WED

    var routes = jsonCustData.filter(function(ele, ind,arr){
        return ele.route_id == route && ele.route_day == day;
    });

    console.dir(routes); // Array[0]


    fillCustomerData(routes);
}

但每次我这样做都会得到一个空数组。我知道我一定做错了什么，但我不知道是什么。

编辑:再次抱歉我的错误，这次我输入了完整的功能。

1. 使用==而不是=
2. 使用Route_day而不是route_day

var objArr = [
{"fname":"tim", "lname":"thompson", "user_id": "2", "route_id": "3", "Route_day": "WED"},
{"fname":"john", "lname":"wilson", "user_id": "3", "route_id": "3", "Route_day": "WED"},
{"fname":"george", "lname":"lane", "user_id": "5", "route_id": "2", "Route_day": "MON"}
];

var newobj = objArr.filter(function(ele, ind, arr){
  console.log(ele);
    return ele.route_id == "3" && ele.Route_day == "WED";
});

console.log(newobj);
