将@font face的javascript绝对URL更改为相对url

Question

现在有了这段javascript，woff字体的url表示绝对的url。如何将其从指向绝对URL更改为相对URL

case 'woff':
        document.write("<style>\n");
                document.write("@font-face {font-family:\"FRHopper430\";src:url(\"" + path + "/webfonts/woff/style_194131.woff\") format(\"woff\");}\n");
                document.write("@font-face {font-family:\"FRHopper431\";src:url(\"" + path + "/webfonts/woff/style_194133.woff\") format(\"woff\");}\n");
                document.write("</style>");
        break;
