KindEditor 4.1.11:

kindeditor-all.js 文件
第772行:

var re = /(\s*)<(\/)?([\w\-:]+)((?:\s+|(?:\s+[\w\-:]+)|(?:\s+[\w\-:]+=[^\s"'<>]+)|(?:\s+[\w\-:"]+="[^"]*")|(?:\s+[\w\-:"]+='[^']*'))*)(\/)?>(\s*)/g;
#改为:
var re = /([ \f\n\r\t\v]*)<(\/)?([\w\-:]+)((?:\s+|(?:\s+[\w\-:]+)|(?:\s+[\w\-:]+=[^\s"'<>]+)|(?:\s+[\w\-:"]+="[^"]*")|(?:\s+[\w\-:"]+='[^']*'))*)(\/)?>([ \f\n\r\t\v]*)/g;

KindEditor 4.1.10:

kindeditor.js 文件
第754行:

var re = /(\s*)<(\/)?([\w\-:]+)((?:\s+|(?:\s+[\w\-:]+)|(?:\s+[\w\-:]+=[^\s"'<>]+)|(?:\s+[\w\-:"]+="[^"]*")|(?:\s+[\w\-:"]+='[^']*'))*)(\/)?>(\s*)/g;
#改为:
var re = /([ \f\n\r\t\v]*)<(\/)?([\w\-:]+)((?:\s+|(?:\s+[\w\-:]+)|(?:\s+[\w\-:]+=[^\s"'<>]+)|(?:\s+[\w\-:"]+="[^"]*")|(?:\s+[\w\-:"]+='[^']*'))*)(\/)?>([ \f\n\r\t\v]*)/g;

其实就是把第一个和最后一个 \s 替换成 [ \f\n\r\t\v]

tip:对于旧版本,先升级到最新版本。因为需要对js文件进行修改,所以引入到页面的js不能是min压缩文件
