Question

我必须遍历数组并用它填充选择框，但是我不想将其附加到html中的元素。我想在变量中将selectbox用作html。

如何将变量frm_str内的selectbox函数结果用作html。

示例：

//users array

{"users":{"48f8fd57-5116-419c-b43a-cff90a4ae39b":"lolololo","4ab9f52a-d445-4b7a-b26d-1f5bc73ea751":"koen","c1d427f2-a39e-4b20-b531-3c325de96d85":"lolololo"}}

        // Setup module
    // ------------------------------
    
    var FullCalendarAdmin = function () {
    
        //
        // Setup module components
        //

var _componentRender = function () {
          _componentFullCalendarAdmin();
        };
    
        //
        // Bootbox message
        //
        var _bootboxContent = function (event, users) {
    
            var _selectUsers = function () {
                var userStr = [];
    
                jQuery.each(users, function (index, item) {
                    userStr.push('<option value="' + index + '">' + item + '</option>');
                });
    
                var object = $('<div/>').html(userStr).contents();
    
                return object;
            }
    
            var frm_str = '<form action="">' +
                '<div class="form-row">' +
                '<label class="col-md-auto col-form-label">Description</label>' +
                '<div class="col-md-8">' +
                '<select>' +
                _selectUsers +
                '</select>' +
                '</div>' +
                '</div>' +
                '</form>';
    
            var object = $('<div/>').html(frm_str).contents();
    
            return object
        }
    
    
        // Basic calendar
        var _componentFullCalendarAdmin = function (events, users) {
    
            // Define element
            var calendarAgendaViewElement = document.querySelector('.fullcalendar-agenda-admin');
    
            // Initialize
            if (calendarAgendaViewElement) {

我使用join()

解决了我的问题

我只需要将数组中的值作为纯html格式，因此使用join可以解决问题：）

感谢所有帮助，尤其是user:mplungjan

let _bootboxContent = function (event, users) {

    let _selectUsers = function () {
        var userArray = [];

        jQuery.each(users, function (index, item) {
            userArray.push('<option value="' + index + '">' + item + '</option>');
        });

        const userStr = userArray.join(" ");

        return userStr;
    }

    const frm_str = '<form action="">' +
        '<div class="form-row">' +
        '<label class="col-md-auto col-form-label">Description</label>' +
        '<div class="col-md-8">' +
        '<select>' +
        _selectUsers() +
        '</select>' +
        '</div>' +
        '</div>' +
        '</form>';

    const object = $('<div/>').html(frm_str).contents();

    return object
}

迭代数组>填充选择框>从函数返回选择框为html
