如果找到匹配项，Javascript 搜索并替换为新字符串

Question

我想搜索一个地址字符串。

如果找到“Southeast”，将其替换为“SE”；

如果找到“Southwest”，将其替换为“SW”；

如果找到“northeast”，将其替换为“NE”；

如果找到“northeast”，将其替换为“NW”。

这是我到目前为止所做的:

 var searchStr = [" Southeast ", " Southwest ", " Northeast ", " Northwest "];
 var replaceStr = [" SE ", " SW ", " NE ", " NW "];
 var oldAddress = $("#address").text();

 for (i=0;i<searchStr.length;i++){
     var n = oldAddress.match(/this[i]/g);
         if(n != null){
            $("#address").text(replaceStr[i]);  
         }                        
 }

它什么也没做，我是不是漏掉了什么？

var newAddress = oldAddress
                    .replace("Southeast", "SE")
                    .replace("Southwest", "SW")
                    .replace("Northeast", "NE")
                    .replace("Northwest", "NW");
$("#address").text(newAddress);
