匹配ASCII的javascript正则表达式
原标题:javascript regular expression to match ASCII

我希望在构建正则表达式以查找ACII代码方面得到帮助

到目前为止,我想出了这个,http://jsfiddle.net/G7cab/

但是你会注意到,我并没有捕捉到所有与这个表达式匹配的组。

I would appreciate some help Many thanks in advance.

以下是(我理解你)根据你的小提琴想要做的事情的简短形式:

var s =  ' ^ hola tio, que tal estas? ! 
          .replace(/(&#d+;)/g,
             function(a){
              return String.fromCharCode(a.substr(2,a.length-3));
             }
           );
 alert(s); //=>   ^ hola tio, que tal estas? !

因此,这里的正则表达式是/(&;#d+;)/g

顺便说一下,&;[#num][name]被调用(数字)html实体。此处的代码仅适用于此类实体(因此,不适用于&;copy;(©)等命名的html实体)。如果要执行此操作(在浏览器中),请使用这个SO问题

我猜您正在尝试取消捕获HTML实体。在SO上进行了讨论:
