要做的就是编写一些数据传播方法，相当简单，这里有一个快速（来自服务器的数据存储在变量requestData中，我也删除了不必要的代码）：

var requestData = [{"name":"phone0", "value":"890890809"},{"name":"fax1", "value":"1111"},{"name":"skype2", "value":"anonononono"},{"name":"email3", "value":"huhuhuhu@huhuhu.pl"}];
function capitalize(string) {
    return string.charAt(0).toUpperCase() + string.slice(1);
}
(function ($) {
    $(function () {
        var addFormGroup = function (event) {
            [...]
        };
        var removeFormGroup = function (event) {
            [...]
        };
        var selectFormGroup = function (event) {
            [...]
        }
        var countFormGroup = function ($form) {
            [...]
        };
        var collectData = function(ele) {
            [...]
        }
        var propagateData = function(data){
            var $formGroup = $('body').find('.form-group');
            $.each(data, function(k,v){
                var $formGroupClone = $formGroup.clone();
                $formGroupClone.find('.btn-add').toggleClass('btn-success btn-add btn-danger btn-remove').html('–');
                $formGroupClone.find('input').val(v.value);
                $formGroupClone.find('.concept').text(capitalize(v.name.replace(/[0-9]/g, '')));
                $formGroupClone.find('.input-group-select-val').val(v.name.replace(/[0-9]/g, ''));
                $formGroupClone.insertBefore($formGroup);
            });
        }
        $(document).on('click', '.btn-add', addFormGroup);
        $(document).on('click', '.btn-remove', removeFormGroup);
        $(document).on('click', '.dropdown-menu a', selectFormGroup);
        propagateData(requestData);
        $('#data').click(function(e){
            collectData('.cache');
            e.preventDefault();
        });
    });
})(jQuery);

好吧，所有重置表单的代码都隐藏在传播数据中，您只需要反转它，在您的 HTML 中您应该添加类似这样的东西<a href="#" class="btn btn-warning form-reset" style="margin: 10px;">Reset</a>然后完整的 js 在这里：

var requestData = [{"name":"phone0", "value":"890890809"},{"name":"fax1", "value":"1111"},{"name":"skype2", "value":"anonononono"},{"name":"email3", "value":"huhuhuhu@huhuhu.pl"}];
function capitalize(string) {
    return string.charAt(0).toUpperCase() + string.slice(1);
}

(function ($) {
    $(function () {
        var addFormGroup = function (event) {
            event.preventDefault();
            var $formGroup = $(this).closest('.form-group');
            var $multipleFormGroup = $formGroup.closest('.multiple-form-group');
            var $formGroupClone = $formGroup.clone();
            $(this)
                .toggleClass('btn-success btn-add btn-danger btn-remove')
                .html('–');
            $formGroupClone.find('input').val('');
            $formGroupClone.find('.concept').text('Phone');
            $formGroupClone.insertAfter($formGroup);
            var $lastFormGroupLast = $multipleFormGroup.find('.form-group:last');
            if ($multipleFormGroup.data('max') <= countFormGroup($multipleFormGroup)) {
                $lastFormGroupLast.find('.btn-add').attr('disabled', true);
            }
        };
        var removeFormGroup = function (event) {

            $selectGroup.find('.input-group-select-val').val(param);
        }
        var countFormGroup = function ($form) {
            return $form.find('.form-group').length;
        };
