How do I filter my javascript constant that I displayed as a table?

Question

I have the following code that will be displayed as a table. I want to filter this content by year through my <select id="ano"> .

All those constants are table rows <tr> .

It is, when I select the <option> 2018 I want to display as a <tr> ONLY those constants which contains the number "2018" within the "Data" variable.

PS: I don't wanna "hide" what is not "2018". I want to "show" what is "2018" ONLY.

Answer 1

I didn't know the values you wanted to display, so I just displayed the dates:

EDIT: Just add more <td> elements for every property you want to display inside the check

document.getElementById("ano").addEventListener("change", function(e) {
    const tbody = document.getElementById('tbody_calendario_jogos')
    while (tbody.firstChild) {
        console.log(tbody.firstChild)
        tbody.removeChild(tbody.firstChild)
    }
    for (key in data) {
        const re = new RegExp(`${e.target.value}`)
        const isVal = re.exec(data[key].Data)
        if (isVal != null) {
            const obj = data[key]
            const tr = document.createElement('tr')

            const tdData = document.createElement('td')
            tdData.textContent = obj.Data

            const tdHora = document.createElement('td')
            tdHora.textContent = obj.Hora

            const tdOponente = document.createElement('td')
            tdOponente.textContent = obj.Oponente

            const tdPlacar = document.createElement('td')
            tdPlacar.textContent = obj.Placar

            const tdTorneio = document.createElement('td')
            tdTorneio.textContent = obj.Torneio

            tr.appendChild(tdData)
            tr.appendChild(tdHora)
            tr.appendChild(tdOponente)
            tr.appendChild(tdPlacar)
            tr.appendChild(tdTorneio)
            tbody.appendChild(tr)
        }
    }
})

EDIT 2: If you want a more concise way of doing this (note: the order of properties matter in this method [aka top is rendered first, bottom is rendered last]) replace the contents of if (isVal != null) { ... } with :

const obj = data[key]
const tr = document.createElement('tr')

for (value of Object.values(obj)) {
    const td = document.createElement('td')
    td.textContent = value

    tr.appendChild(td)
    console.log(value)
}

tbody.appendChild(tr)

This activates every time the value of the select changes (aka whenever the user chooses an option), removes all elements of "tbody_calendario_jogos" , uses Regex to filter the correct objects by their year and displays them.

PS: I organized your data into this for the code to work:

const data = {
    LSB_2018_JOGO_1: {
        Data: "11/03/2019",
        Hora: "15:00",
        Oponente: "BMC",
        Placar: "V, 52-42",
        Torneio: "LSB",
    },
    LSB_2018_JOGO_2: {
        Data: "08/04/2018",
        Hora: "12:30",
        Oponente: "Drink Team",
        Placar: "D, 59-61",
        Torneio: "LSB",
    },
    LSB_2018_JOGO_3: {
        Data: "22/04/2019",
        Hora: "10:30",
        Oponente: "Nitcheroy Ballers",
        Placar: "V, 53-40",
        Torneio: "LSB",
    },
    TUC_2018_JOGO_1: {
        Data: "11/08/2018",
        Hora: "12:30",
        Oponente: "Unirio",
        Placar: "D, 30-60",
        Torneio: "TUC",
    },
    TUC_2018_JOGO_2: {
        Data: "15/09/2019",
        Hora: "17:10",
        Oponente: "UFRJ Aecs",
        Placar: "V, 29-25",
        Torneio: "TUC",
    },
    TUC_2018_JOGO_3: {
        Data: "20/10/2018",
        Hora: "16:00",
        Oponente: "UERJ Economia",
        Placar: "V, 49-30",
        Torneio: "TUC",
    }
};
