javascript中怎么用server.urlencode处理特殊字符

[suisuibianbian]

fsubmit(){
strLocation ="aaa.asp?Code="+FORMMAIN.TXTARCNO. value;
strLocation = strLocation + "&Name=" + FORMMAIN.TXTARCNAME.value;
strLocation = strLocation + "&Type=" + FORMMAIN.CBXTYPE.value;
strLocation = strLocation + "&Remark=" + FORMMAIN.TXAREMARK.value;
FORMMAIN.action = strLocation;
FORMMAIN.method = "post";
FORMMAIN.submit();
}
当FORMMAIN.TXTARCNAME.value有特殊字符时就会出错,怎么像vbscript中一样用
server.urlencode(FORMMAIN.TXAREMARK.value)
