js 两个以“，”分割的字符串去重，然后组合
var astr = "a,b,c,d,"
var bstr = "a,c,f,e,w";
我想要的结果是 "a,b,c,d,f,e,w"
请高手帮忙

[解决办法]

JScript code

var astr = "a,b,c,d";var bstr = "a,c,f,e,w"; var s = "," + astr + ","var a  = bstr.split(",");for(var i=0;i<a.length;i++){   if(s.indexOf(","+ a[i] +",")==-1){      s += a[i] + ",";   }    }s = s.substr(1,s.length-2);alert(s)
