如果这种判断index是否为0的技巧和g flag一起用，可以同时处理单行和多行的commen
t。对吧？


function removeLeadingComment(inputStr){

        var nRemoved = 0;

        return inputStr.replace(/(?:\s*\/\/.*\n|\s*\/\*[\s\S]*?\*\/)/g,

                function(str,offset){

                        //alert(str + offset + "-" + nRemoved);
                        if(offset == nRemoved){

                                nRemoved += str.length;

                                return "";

                        } else {

                                return str;

                        }

                        

                });

}
