typecho 网页报错：`Uncaught SyntaxError: Invalid or unexpected token`

[Y2hpbG9o]

下了个 typecho 模板，发现Uncaught SyntaxError: Invalid or unexpected token这个问题，定位了下，好像是下面这段代码导致的。

麻烦大佬帮忙看一下，正确的写法该怎么写（貌似是最后两行的问题），谢谢~

<script type="text/javascript">
    (function () {
            var event = document.addEventListener ? {
                    add: 'addEventListener',
                    triggers: ['scroll', 'mousemove', 'keyup', 'touchstart'],
                    load: 'DOMContentLoaded'
                } : {
                    add: 'attachEvent',
                    triggers: ['onfocus', 'onmousemove', 'onkeyup', 'ontouchstart'],
                    load: 'onload'
                },
                added = false;
            document[event.add](event.load, function () {
                        var r = document.getElementById('respond-post-14'),
                            input = document.createElement('input');

                        input.name = '_';
                        input.value = (function () {
