javascript判斷是否含有全形

function resolvUgcChar(str){
         for (i = 0; i < str.length; i++){
        var c = str.charAt(i);
        if(c == '?' || c == '？' || c == '&' || c == '<'
           || c == '>' || c == '\'' || c == '‘' || c == '\"' || c == '“' || c == '”'
           || c == '@' || c == '#'  || c == '\\'
           || c == '\/'|| c == '$'  || c == '\^'
           || c == ';' || c == '；' || c == ':' || c == '：'  || c == '%'
           || c == '!' || c == '！' || c == '|')
        {
            return true;
        }
        /////////////全形處理/////////////////
                strCode=str.charCodeAt(i);
            if((strCode>65248)||(strCode==12288))
            {
            //alert("有全形");
            return true;
            }
