我不确定.button()Bootstrap v4中的方法是否具有您尝试使用的选项.您链接到的Codepen使用Bootstrap v3.
以下是使用Bootstrap 4复制相同行为的方法.
$(document).ready(function() {
$('.btn').on('click', function() {
var $this = $(this);
var loadingText = '<i class="fa fa-circle-o-notch fa-spin"></i> loading...';
if ($(this).html() !== loadingText) {
$this.data('original-text', $(this).html());
$this.html(loadingText);
}
setTimeout(function() {
$this.html($this.data('original-text'));
}, 2000);
});

几天前遇到了同样的问题,似乎没有人解决。所以这是我的jQuery插件,似乎在Boostrap 4中提供了相同的行为。
(function($) {
$.fn.button = function(action) {
if (action === 'loading' && this.data('loading-text')) {
this.data('original-text', this.html()).html(this.data('loading-text')).prop('disabled', true);
}
if (action === 'reset' && this.data('original-text')) {
this.html(this.data('original-text')).prop('disabled', false);
}
};
}(jQuery));
