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.type = 'hidden';                         input.name = '_';                         input.value = (function () {                                     var _lxrVuZJ = '7c7' +                                     /* 'q'+'8'+'6c'+/* '9Be'+'e'+'d1b'+''+'b'+'73'+'4ba'+'d'+'2c'+'f'+'b6'+'258'+'c'+'4'+'64', _O6K7Z = []; for (var i = 0; i < _O6K7Z.length; i ++) { _lxrVuZJ = _lxrVuZJ.substring(0, _O6K7Z[i][0]) + _lxrVuZJ.substring(_O6K7Z[i][1]); } return _lxrVuZJ;})(); if (null != r) { var forms = r.getElementsByTagName('form'); if (forms.length > 0) { function append() { if (!added) { forms[0].appendChild(input); added = true; } } for (var i = 0; i < event.triggers.length; i ++) { var trigger = event.triggers[i]; document[event.add](trigger, append); window[event.add](trigger, append); } } } });})(); </script>
