我有一组div，我显示后，我点击一个选项从选择。数据选项在重新加载后保存，以保持选项处于选中状态。这是正确的，但问题是onreload，我想保存值div来显示它，但我不知道如何做到这一点：看：
这是我的div组：

这是我的选择：

<select id="sort-item" class="term">
                <option data-sort="0">Elija una opción</option>
                @foreach (var nivel in Model)
                {
                    if (nivel.nivel == 0 || nivel.nivel == 1 || nivel.nivel == 2 || nivel.nivel == 7)
                    {
                        <option value="cerDiv" data-sort="1">Certificados</option>
                        <option value="cuoDiv" data-sort="2">Cuotas</option>
                    } 
                }
            </select>

我的js文件中有一个this：

let selItems = JSON.parse(sessionStorage.getItem("SelItem")) || [];
var div_status = JSON.parse(sessionStorage.getItem("div_status")) || [];

$(function () {
    if (selItems) {
        selItems.forEach(obj => {
            const [k, v] = Object.entries(obj)[0]
            $("#" + k).val(v)
        })
    }
    $('.term').on("change", function () {
        selItems = $('.term').map(function () {
            return {
                [this.id]: this.value
            }
        }).get();
        console.log(selItems)
        sessionStorage.setItem("SelItem", JSON.stringify(selItems));
        saveDiv(this.value);
    });
});

function saveDiv(div) {
    div_status[div] = true;
    sessionStorage.setItem("div_status", JSON.stringify(div_status));
}

window.onload = function () {
    console.log(div_status);
    Object.values(div_status).forEach(function (div) {
        monstrarDiv(document.querySelector("#" + div))
    });
}

function mostrarDiv(target) {
    var opciones = document.getElementsByClassName('opc');
    var tagt = document.getElementById(target);
    var esVisible = tagt.style.display == 'block';

    //hide all
    for (var i = 0; i < opciones.length; i++) {
        opciones[i].style.display = 'none';
    }

    //toggle actual
    tagt.style.display = esVisible ? 'none' : 'block';

    return false;
}

我尝试更改代码，但没有任何工作，因为我不知道如何调用值来显示div。
