Google Apps脚本可从网页获取数据 [英] Google apps script to grab data from webpage

问题描述

在制作此脚本之前，我曾提供过帮助，可以将玩家人数从网站上提取下来，并将其登录到带有日期和时间戳的电子表格中，这是:

I had help making this script before that would pull the playercount off a website and log it into spreadsheets with a date and timestamp, this was:

function pullRuneScape() {
  var page = UrlFetchApp.fetch('http://runescape.com/title.ws').getContentText();
  var number = page.match(/PlayerCount.*>([0-9,]+)</)[1];
  SpreadsheetApp.getActive().getSheetByName('RuneScape').appendRow([new Date(), number]);
}

基本上，他们在网页上列出了玩家数量，我想每5分钟左右记录一次，但他们也有另一个网站，我也想从中获取人数，我需要一些帮助.

Basically in the webpage they list the amount of players and I wanted to log it every 5minutes or so, but they have another site I wanted to grab the number from too and I need some help.

它位于 http://oldschool.runescape.com/slu

我想在该网站的顶部获取玩家人数，并像在这里一样记录它:

I wanted to grab the player count on that site, at the top, and log it just like I have here: https://docs.google.com/spreadsheet/ccc?key=0AjrAPynUEUl9dGtIZFY0TlRFUllVcWFyZDZ2c2o5Tnc#gid=0

A列是日期和时间，B列是人数，因此输出将类似于1/1/2013 0:00:48 77,439

Where column A is the date and time, and B is just the number of people, so the output would be like 1/1/2013 0:00:48 77,439

谢谢您的帮助.
