Get JavaScript object from array of objects

Question

I have an array of four objects:

this return array of obejcts

var arrProducts = @Model.ViewModel_SessionObject.GetJsonProducts();

var arrProducts = [
{"RateCode":"IBE","RoomCode":"A1D","IDSharedAvailability":0,"TotalRooms":"4 rooms available","SelectedRooms":0},
{"RateCode":"PR2","RoomCode":"A1D","IDSharedAvailability":0,"TotalRooms":"4 rooms available","SelectedRooms":0},
{"RateCode":"IBE","RoomCode":"B2T","IDSharedAvailability":0,"TotalRooms":"7 rooms available","SelectedRooms":0},
{"RateCode":"PR2","RoomCode":"B2T","IDSharedAvailability":0,"TotalRooms":"7 rooms available","SelectedRooms":0}];

Is there a way that I can get the object when i click on anchor tag this view of my list of all object , to be more clear i want select or find the object by RoomCode and RateCode when i click on the anchor tag .

@foreach (var item in Model.ViewModel_SessionObject.HotelAvailabilityRSObject.RoomTypes)  // rooms Loop
{
    HotelDetailsRSRoomType RoomDetails = Model.ViewModel_SessionObject.HotelDetailsRSObject.GetRoomTypeByCode(item.RoomCode);
    if (RoomDetails != null)
    {
        <div style="border-left: 1px solid #fff;border-right: 1px solid #fff;padding: 10px;border-bottom:  1px solid #fff;background-color: #fff; ">

            <!--Rate describtion-->

                            </div>
                        }
                    </div>
                </div>
            </div>
            <!--End rooms section-->
        </div>
    }
}

I tried this function but it gives or return all objects when i click on anchor tag but i need specific object i selected by anchor :

<script type="text/javascript">
    function SelectRooms(arrProducts) {
        var filterObj = arrProducts.filter(function (e) {
            return e.
        });

     };
</script>

You have to actually filter based on something. Where is the RoomCode and RateCode coming from ? — adeneo

The method you pass to filter must return truthy value for any item(s) you want to return.

function SelectRooms(arrProducts) {
    var filterObj = arrProducts.filter(function (e) {
        return e.RateCode === "IBE" && e.RoomCode === "A1D";
    });
    return filterObj[0]; // first/single item
 };

Where you get the values from (IBE and A1D in the above example) is up to you

I'm not 100% sure what you want exactly but I guess your mistake was to not pass the roomcode/roomrate not to your function. If that's the case you may find this useful:

Get room by "RoomCode" as a single object:

function getRoom(arrProducts, code){
    //for modern browsers (> ie 11)
    return arrProducts.find(x => x.RoomCode === code);

    //for a bit older ones
    return arrProducts.filter(function(x) {
        return x.RoomCode === code;
    }).pop();

    //for really old ones
    for(var i = arrProducts.length; i--;;){
        if (arrProducts[i].RoomCode === code) return arrProducts[i];
    }

    return null;
}

Get rooms by "RoomRate" as an array:

function getarrProducts(arrProducts, rate) {
    //for modern browsers (> ie 11)
    return arrProducts.filter(x => x.RoomRate === rate);

    //for a bit older ones
    return arrProducts.filter(function(x) {
        return x.RoomRate === rate;
    });

    //for really old ones
    var results = [];
    for(var i = arrProducts.length; i--;;){
        if (arrProducts[i].RoomRate === rate) results.push(arrProducts[i]);
    }
    return results;
}

Update

In case you need the room by "RoomCode" and "RoomRate" you can do it like this:

function getRoom(arrProducts, code, rate) {
    //for modern browsers (> ie 11)
    return arrProducts.find(x => x.RoomCode === code && x.RoomRate === rate);

    //for a bit older ones
    return arrProducts.filter(function(x) {
        return x.RoomCode === code && x.RoomRate === rate;
    }).pop();

    //for really old ones
    for(var i = arrProducts.length; i--;;){
        if (arrProducts[i].RoomCode === code && x.RoomRate === rate) return arrProducts[i];
    }

    return null;
}

right ,this what i need , but i want to Get room by "RoomCode" and "RateCode" together as a single object
