Question

在this site的帖子中，有很多人都很棒。
但是我需要根据我的需要修改这个脚本。

我不是硬核编码器，但在没什么帮助的情况下我可以让它工作。

我的网站上有HH：MM AM / PM格式的时间戳这就是我网站上的内容。

Last Updated as of 11:14 pm March 11th

我想解析2:14 PM并将其与当前时间戳进行比较（减去它），然后得到分钟数。如果差异大于30分钟，那么我希望它能做点什么。

有人可以帮我吗？感谢

我正在努力理解和修改此代码 仅供参考 Google.com就是一个例子，而不是谷歌，它将链接到mysite。

@echo off
setLocal EnableDelayedExpansion
set curTimestamp=%date:~7,2% %date:~3,3%_%date:~10,4%_%time:~0,2%_%time:~3,2%

Answer 1

这是一个批处理脚本/ JScript混合使用JScript能够使用日期执行数学运算。由于网页从未指定，因此该脚本假定年份此年，因此如果文档在12月最后一次修改，您可能会在1月初运行此结果。无论如何，这里。

@if (@X)==(@Y) @end /* (batch + jscript hybrid script init)

:: *** Batch script *****

@echo off
setlocal enabledelayedexpansion
for /f "delims=" %%I in ('wget "%~1" -O- -q 2^>NUL ^| findstr /i "last.*updated.*as.*of"') do (
    for /f "delims=" %%x in ('cscript /nologo /e:jscript "%~f0" "%%I"') do (

        rem test whether date diff >= 30 minutes
        set /a "thirtyMinutes = 30 * 60 * 1000"
        if %%x GEQ !thirtyMinutes! (
            echo Do that voodoo that you do.
        )

        rem Just to demonstrate, you can do some maths to make further sense of the date difference.
        rem set milliseconds=%%x
        set /a "seconds = %%x / 1000, seconds %%= 60"
        set /a "minutes = %%x / 1000 / 60, minutes %%= 60"
        set /a "hours = %%x / 1000 / 60 / 60, hours %%= 24"
        set /a "days = %%x / 1000 / 60 / 60 / 24"
        echo %~1 last modified !days! days !hours! hours !minutes! minutes ago.
    )

    rem Once the for loop has fired, exit.
    exit /b
)

rem In case the web page does not contain "last updated as of"
exit /b

var args = [];
for (var i=0; i<WScript.arguments.length; i++) { args.push(WScript.arguments(i)) }
var t = args.join(' ').replace(/^\s+|<[^>]+>|\s+$/g,'').replace(/\&nbsp;/g, ' ').split(' ');
var h = t[4].split(':')[0];
if (/pm/i.test(t[5])) h = h * 1 + 12;
var ds = t[6] + ' ' + t[7] + ', ' + new Date().getFullYear() + ' ' + h + ':' + t[4].split(':')[1];
var diff = new Date() - new Date(ds);

@echo off
set timeStamp=Last Updated as of 2:14 pm March 11th

rem Convert time of timeStamp to number of minutes
for /F "tokens=5-7 delims=: " %%a in ("%timeStamp%") do (
   set /A minutes=%%a*60 + 1%%b%%100
   if %%c equ pm set /A minutes+=12*60
)

rem Subtract that number of minutes from current time
for /F "tokens=1-2 delims=:" %%a in ("%time%") do (
   set /A minutes=%%a*60 + 1%%b%%100 - minutes
)

rem If time lapse is negative, timeStamp was taken from previous day
if %minutes% lss 0 (
   set /A minutes+=24*60
)

if %minutes% gtr 30 (
   echo Do something...
)

我们可以从html站点获取/抓取特定数据到批处理以执行以下操作吗？
