Javascript替换不会替换

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," ") 

在此先感谢

Answer 1

你的正则表达式是一个字符串，这将尝试更换该字符串完全相同。正则表达式对象周围没有引号，只是分隔符。试着这样说：

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," ");

或者如果你喜欢的字符串（和更明确的类型）：

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