正则替换多个匹配的问题

[vss2002]

原始字符串内有一些自定义的域，现在想替换成实际的值，试了一下好象不行

var ss = "The_{sc} rain_{st} in_{sx} Spain{sc} falls{sc}\n mainly_{st} in{st} {sx}{sc}the{st} plain{s}.";
var sc = "(this is sc)", st = "[dd/xx]", sx= "|haha|";
var r, re;
re = /(\{sc\})(\{st\})(\{sx\})/g;//这么写对吗？
r = ss.replace(re, sc); //？这句要怎么写
alert(r);


由于{*}中定义的标签比较多，不要那种进行循环replace的方法

谢谢，怎么就钻了牛角尖呢

var re = /\{\w+\}/g

<script language=javascript>
var ss = "The_{sc} rain_{st} in_{sx} Spain{sc} falls{sc}\n mainly_{st} in{st} {sx}{sc}the{st} plain{s}.";
var temp=new Array();
temp["sc"]="(this is sc)";
temp["st"]="[dd/xx]";
temp["sx"]="|haha|";
re = /\{((sc|st|sx))\}/g;
r = ss.replace(re, function(a,b){return temp[b]});
alert(r);
</script>
