我正在尝试使用MVC JavaScript函数启用/禁用下拉菜单

Question

当未选中启用复选框时，我正在尝试禁用这些下拉菜单。这是我第一次解决这个问题，任何指导都将不胜感激。

基本上，当禁用复选框时，我试图禁用下拉菜单。检查复选框时，需要启用下拉列表。

JS：

$(document).ready(function () {
    if ($("#userPermissions").checked) {
        enableAll();
        console.log("enableAll");
    } else {
        disableAll();
        console.log("disableAll");
    }
})
$('#userPermissions').change(function (e) {
    //console.log('change');
    if (this.checked) {
        enableAll();
        console.log('change1');
    } else {
        disableAll();
        console.log('change2');
    }
});
function enableAll() {
    $("#userSettingsBottom  :input").prop("disabled", false);
    console.log("enabled");
}
function disableAll() {
    $("#userSettingsBottom  :input").prop("disabled", true);
    console.log("disabled");
}

cshtml：

<div class="row">

因为这些是kendo下拉s，为什么不使用kendo功能？首先，名称应源自模型字段。在这种情况下，model.deliveruseridfield的默认示例将为

$("#DeliverUserIDField").data("kendoDropDownList").enable(false);
