引言

str = StringUtil.trim(str);

你们应该能够使用reg,例如:

var pattern:RegExp = /(	|
|s{2,})/g;  
trimmedString = untrimmedString.replace(pattern,   );

《战争》的解决方案并没有拆除拖车空间。

Amargosh的解决方案对我来说是完美无缺的,还见。

幸运的是,我没有足够的声誉来投票解决阿马戈什问题。

此外,我不得不在这里删除两句:

function trim( s:String ):String
{
  return s.replace(/^[s|"]+|[s|"]+$/gs,   );
}
