I need the below output using a for loop as the output is a JSON object and I am not able to write for loop.

Any Suggestions would be a great help....

JavaScript

if (($('#tbl_Capacity tr').length - 1)==1)
    listcapac = [{ "roomId": 0, "capacity": $('#inputrowid' + 0).val() }]

if (($('#tbl_Capacity tr').length - 1) == 2)
    listcapac = [{ "roomId": 0, "capacity": $('#inputrowid' + 0).val() }, { "roomId": 1, "capacity": $('#inputrowid' + 1).val() }]

if (($('#tbl_Capacity tr').length - 1) == 3)
    listcapac = [{ "roomId": 0, "capacity": $('#inputrowid' + 0).val() }, { "roomId": 1, "capacity": $('#inputrowid' + 1).val() },
    { "roomId": 2, "capacity": $('#inputrowid' + 2).val() }]

if (($('#tbl_Capacity tr').length - 1) == 4)
    listcapac = [{ "roomId": 0, "capacity": $('#inputrowid' + 0).val() }, { "roomId": 1, "capacity": $('#inputrowid' + 1).val() },
    { "roomId": 2, "capacity": $('#inputrowid' + 2).val() }, { "roomId": 3, "capacity": $('#inputrowid' + 3).val() }]

if (($('#tbl_Capacity tr').length - 1) == 5)
    listcapac = [{ "roomId": 0, "capacity": $('#inputrowid' + 0).val() }, { "roomId": 1, "capacity": $('#inputrowid' + 1).val() },
    { "roomId": 2, "capacity": $('#inputrowid' + 2).val() }, { "roomId": 3, "capacity": $('#inputrowid' + 3).val() },
    { "roomId": 4, "capacity": $('#inputrowid' + 4).val() }]

if (($('#tbl_Capacity tr').length - 1) == 6)
    listcapac = [{ "roomId": 0, "capacity": $('#inputrowid' + 0).val() }, { "roomId": 1, "capacity": $('#inputrowid' + 1).val() },
    { "roomId": 2, "capacity": $('#inputrowid' + 2).val() }, { "roomId": 3, "capacity": $('#inputrowid' + 3).val() },
    { "roomId": 4, "capacity": $('#inputrowid' + 3).val() }, { "roomId": 5, "capacity": $('#inputrowid' + 5).val() }]

if (($('#tbl_Capacity tr').length - 1) == 7)
    listcapac = [{ "roomId": 0, "capacity": $('#inputrowid' + 0).val() }, { "roomId": 1, "capacity": $('#inputrowid' + 1).val() },
    { "roomId": 2, "capacity": $('#inputrowid' + 2).val() }, { "roomId": 3, "capacity": $('#inputrowid' + 3).val() },
    { "roomId": 4, "capacity": $('#inputrowid' + 4).val() }, { "roomId": 5, "capacity": $('#inputrowid' + 5).val() },
    { "roomId": 6, "capacity": $('#inputrowid' + 6).val() }]

if (($('#tbl_Capacity tr').length - 1) == 8)
    listcapac = [{ "roomId": 0, "capacity": $('#inputrowid' + 0).val() }, { "roomId": 1, "capacity": $('#inputrowid' + 1).val() },
    { "roomId": 2, "capacity": $('#inputrowid' + 2).val() }, { "roomId": 3, "capacity": $('#inputrowid' + 3).val() },
    { "roomId": 4, "capacity": $('#inputrowid' + 3).val() }, { "roomId": 5, "capacity": $('#inputrowid' + 5).val() },

Solution 2

Converting this to a for loop seems simple enough:

JavaScript

listcapac = [];
var rooms = $('#tbl_Capacity tr').length - 1;
for (var i = 0; i < rooms; i++) {
    listcapac.push({
        "roomId": i,
        "capacity": $('#inputrowid' + i).val()
    });
}

Solution 1

JSON serialization is already available. See, for example,
JSON.stringify() — JavaScript | MDN[^],
JSON.parse() — JavaScript | MDN[^].

See also: JSON — JavaScript | MDN[^].
