如图，给ckeditor添加了表情，用的是官网的插件（http://官网.com/addon/smiley），但是添加成功后无法发起问题或者发表回复，点击“确认发起”或者“回复”按钮无任何反应。   调试发现错误提示：“Uncaught TypeError: Cannot read property 'replace' of undefined”； 问题出现在static/js/ediotor/ckeditor/ckeditor.js第685行： “c.entities_additional&&e.push(c.entities_additional));var a=i(e.join(",")),d=a.regex?"["+a.regex+"]":"a^";delete a.regex;c.entities&&c.entities_processNumerical&&(d="[^ -~]|"+d);var d=RegExp(d,"g"),h=i("nbsp,gt,lt,amp,shy",!0),j=RegExp(h.regex,"g");b.addRules({text:function(a){return a.replace(j,f).replace(d,g)}},{applyToAll:!0,excludeNestedEditable:!0})}}})})();CKEDITOR.config.basicEntities=!0;CKEDITOR.config.entities=!0;CKEDITOR.config.entities_latin=!0;CKEDITOR.config.entities_greek=!0;” 然后下载了ckeditor4.4.6的full版，发现对应的原始代码在第711行： “b.entities_additional&&d.push(b.entities_additional));var e=j(d.join(",")),f=e.regex?"["+e.regex+"]":"a^";delete e.regex;b.entities&&b.entities_processNumerical&&(f="[^ -~]|"+f);var f=RegExp(f,"g"),c=function(a){return b.entities_processNumerical=="force"||!e[a]?"&#"+a.charCodeAt(0)+";":e[a]},g=j("nbsp,gt,lt,amp,shy",!0),i=RegExp(g.regex,"g"),k=function(a){return g[a]};a.addRules({text:function(a){return a.replace(i,k).replace(f,c)}},{applyToAll:!0,excludeNestedEditable:!0})}}})})();” 看的头大，请问该如何修改？ 急盼回复，不胜感激。
