jQuery，get Uncaught TypeError：Object [object Number]没有方法'apply'

Question

我正在使用Nadia Alramli的Jquery插件“确认”。我在这个插件中添加了一些功能，但是得到了这样的错误：“未捕获的TypeError：对象[对象编号]没有方法'应用'”，我检查了，真的无法搞清楚，请帮忙......

    jQuery.fn.confirm = function(options) {
            options = jQuery.extend({

                eventType: 'click', dialogShow: 'show', dialogSpeed: '', timeout: 0,

                //**belows are what I added**
                wrapperLeft: 0, wrapperTop: 0,
                outerWrapper: '<span class="relative"></span>',
                mask: '<span class="confirmMask"></span>',
