使用GI標誌從變量

Question

var metin = "baris"; 
var icerikoku = "Hello Baris. What is surname Baris. Bye bye baris. How are you metin."; 
var n = icerikoku.replace(/metin/gi, "ziya"); 
$("#icerikoku").html(n); 

打印創建一個正則表達式：
Hello Baris. What is surname Baris. Bye bye baris. How are you ziya.

，但必須是：
Hello ziya. What is surname ziya. Bye bye ziya. How are you metin.

Answer 1

您需要使用RegExp構造爲：

var n = icerikoku.replace(new RegExp(metin, 'gi'), "ziya"); 

這將允許您將變量傳遞到您的正則表達式。
