Question

嘿我试图从节点中的HTML请求结果中访问全局变量。我目前可以使用cheerio模块访问节点，但是我对如何访问全局页面变量感到难过？

＆＃13;

private static final String PARSE_PATTERN = "yyyy-MM-dd'T'HH:mm:ssXXX";
private static final String FORMAT_PATTERN = "MM/dd/yyyy";
// we cannot declare the SimpleDateFormat as static since it isn't thread-safe

public static String formatResolutionTime(String startDateString) {

    try {
        DateFormat parser = new SimpleDateFormat(PARSE_PATTERN);
        Date startDate = parser.parse(startDateString);

        DateFormat formatter = new SimpleDateFormat(FORMAT_PATTERN);
        return formatter.format(startDate);
    } catch (ParseException e) {
        // e.printStackTrace();
        return "Error"; // or whatever, but return a string here
    }
}

Cheerio无权访问浏览器的java脚本全局变量。它只能解析html页面的DOM结构。
