剥离标点符号的正则表达式也错误地剥离了空格。救命 :(

可能重复:
  This regex to strip punctuation also incorrectly makes the word Báenou into Benou

我写了以下正则表达式删除标点字符

var myTxt = "Welcome, Visitor: The Royal Kingdom Of Báenou";
myTxt = myTxt.replace(/[^a-zA-Z0-9 ]+/g, '').replace('/ {2,}/',' ');
alert(myTxt);

所以上面的文字应该变成这样:

Welcome Visitor The Royal Kingdom Of Báenou

但是错误地将Báenou中的á掉了下来产生这个:

Welcome Visitor The Royal Kingdom Of Benou

所以在朋友们的帮助下,我将正则表达式修改为下面的那个

var myTxt = "Welcome, Visitor: The Royal Kingdom Of Báenou";
myTxt =

我下载了Xregexp以尝试更有效地执行此操作,但我不确定如何在Xregexp中编写此正则表达式。

任何帮助都将不胜感激。

3 个答案:

答案 0 :(得分:1)
