Question

此代码中的模式不会替换括号。我也试过“/（|）/ g”。

var re = "/[^a-z]/g",
   txt = navsel.options[i].text.split(" ")[0], // here I get the text from a select and I split it.
   // What I expect is strings like "(en)" , "(el)" etc
   txt = txt.replace(re," ")

提前致谢

Answer 1

你的正则表达式是一个字符串，这将尝试替换那个确切的字符串。正则表达式对象周围没有引号，只有分隔符。试试这样：

var re = /[^a-z]/g,
   txt = navsel.options[i].text.split(" ")[0], // here I get the text from a select and I split it.
   txt = txt.replace(re," ");

或者如果您更喜欢字符串（以及更明确的类型）：

var re = new RegExp("[^a-z]", "g")

Javascript替换不替换
