JavaScript的正則表達式不區分大小寫

Question

請看這JsFiddle。

var target = "Thanks For Looking This Problem"; 
var phrase = ["anks", "for", "king T"]; 

for(var indx = 0; indx < phrase.length; indx ++) 
{ 
    target = target.replace(new RegExp(phrase[indx], "gi"), "~~~" + phrase[indx]+ "```"); 
} 
​ 

我得到這樣的輸出：Th~~~anks``` ~~~for``` Loo~~~king T```his Problem

但我需要這樣的輸出：Th~~~anks``` ~~~For``` Loo~~~king T```his Problem

'對於' 而不是 '爲'

Answer 1

只是不要replace通過這句話，但由匹配的字符串組成：

… target.replace(new RegExp(phrase[indx], "gi"), "~~~$&```"); 

有了這個，你不妨刪除這個循環並只使用

return target.replace(new RegExp(phrase.join("|"), "gi"), "~~~$&```")
