Javascript 使用greasemonkey存储或记录数据，可在以后处理

我现在正忙于一个网站，我想为它编写一个greasemonkey脚本，记录所有数据，或者至少记录其中的某些帖子，并保存在一个可以与ms excell交互的文件中。可能吗？比如说，我拿这段数据为例：

 {"d":[["","","y","ZAR","1","49517","6458, 8270, 8270, 8270, 7635",null,"1.40","6458","0:13:30","","12","","C","30",null],["y","-00:00","y","ZAR","2","49593","6458, 6458, 6458, 6458, 6458",null,"2.92","6458","0:13:37","","12","","L","12","Ve4mYdrvkkQMKxBH1\/1VMtDTCDQBRspg5jB8jjY08zg="],["","","y","ZAR","3","49058","7456, 9216, 6458, 5153, 7456",null,"194.40","7456","0:00:31","","1100","","T",null,null],["","","y","ZAR","4","49597","2935, 6554",null,"1.22","2935","0:01:16","","12","","T",null,null],["","","y","ZAR","5","49590","4440, 0518, 5343, 2625, 4848",null,"0.95","4440","0:15:58","","5","","L",null,null],["","","y","ZAR","6","49591","4848, 4440, 4440, 0518, 2625",null,"1.81","4848","0:16:05","","12","","L",null,null],["","","y","ZAR","7","49595","6458",null,"5.55","6458","0:04:13","","55","","T",null,null],["","","y","ZAR","8","49596","",null,"2.90","NONE","0:04:35","","29","","T",null,null],["","","y","ZAR","9","49496","6458, 2427, 2427, 7863, 5845",null,"2.56","6458","0:06:07","","10","","B",null,null],["","","y","ZAR","10","49524","6458, 2427, 7863, 7863, 5845",null,"1.67","6458","0:06:00","","5","","B",null,null],["","","y","ZAR","11","49539","6458, 2427, 7863, 7863, 0764",null,"2.02","6458","0:04:25","","10","","B",null,null]]}

，将其读入2d数组，Brock Adams帮我完成了这项工作

var myJson              = '{"d":[["","","y","ZAR","1","49517","6458, 8270, 8270, 8270, 7635",null,"1.40","6458","0:13:30","","12","","C","30",null],["y","-00:00","y","ZAR","2","49593","6458, 6458, 6458, 6458, 6458",null,"2.92","6458","0:13:37","","12","","L","12","Ve4mYdrvkkQMKxBH1\/1VMtDTCDQBRspg5jB8jjY08zg="],["","","y","ZAR","3","49058","7456, 9216, 6458, 5153, 7456",null,"194.40","7456","0:00:31","","1100","","T",null,null],["","","y","ZAR","4","49597","2935, 6554",null,"1.22","2935","0:01:16","","12","","T",null,null],["","","y","ZAR","5","49590","4440, 0518, 5343, 2625, 4848",null,"0.95","4440","0:15:58","","5","","L",null,null],["","","y","ZAR","6","49591","4848, 4440, 4440, 0518, 2625",null,"1.81","4848","0:16:05","","12","","L",null,null],["","","y","ZAR","7","49595","6458",null,"5.55","6458","0:04:13","","55","","T",null,null],["","","y","ZAR","8","49596","",null,"2.90","NONE","0:04:35","","29","","T",null,null],["","","y","ZAR","9","49496","6458, 2427, 2427, 7863, 5845",null,"2.56","6458","0:06:07","","10","","B",null,null],["","","y","ZAR","10","49524","6458, 2427, 7863, 7863, 5845",null,"1.67","6458","0:06:00","","5","","B",null,null],["","","y","ZAR","11","49539","6458, 2427, 7863, 7863, 0764",null,"2.02","6458","0:04:25","","10","","B",null,null]]}'
var jsonObj             = $.parseJSON (myJson);

//--- The JSON should return a 2-D array, named "d".
var arrayOfAuctions     = jsonObj.d;

//--- Loop over each row in the array.
$.each (
    arrayOfAuctions,
    function (rowIndex, singleAuctionData) {

        //--- Print the 7th column.
        console.log ('Row: ' + (parseInt (rowIndex) + 1) + ' Column: 7  Value: ' + singleAuctionData[6]);
    }
);

现在我想把这个数组的数据写入一个文件，以后我可以在excell中打开这个文件并查看它。通过使用GM_setValue，可以做到这一点吗？最简单的方法是如何继续下去

---

谢谢。

Greasemonkey无法写入文件，使用

GM_setValue

或本地存储将很难进入文件。无论如何，您都不想使用

GM_setValue

存储太多的值，因为这些值存储在浏览器首选项中

您提到了远程服务器。
是的，GM可以将数据发送到远程服务器（如果您的本地计算机正在运行类似XAMPP的东西，甚至可以发送到您的本地计算机）。再多做一点工作，你也可以把数据发送到谷歌文档或类似的网站上

不清楚您要发送什么数据（假设您不只是发送整个

阵列故障

）

比如说，您已经分析了数据并确定需要这些列：

Column Index Meaning / Purpose ------ -------------------------------- 4 Auction display number 5 Auction ID 8 Current Price 9 High bidder ID 10 Time Remaining 12 Up to???
并将其发送到服务器，如下所示：

SerializedAuctionData  = JSON.stringify (myAuctionData);

GM_xmlhttpRequest ( {
    method:     "POST",
    url:        "http://localhost/YourDir/LogAuctionData.php",
    data:       SerializedAuctionData,
    headers:    {"Content-Type": "application/json"}
} );

服务器可以使用您熟悉的任何技术。
如果是PHP页面，它可以提取JSON数据，如下所示：

$AuctionData = json_decode($HTTP_RAW_POST_DATA);
print_r ($AuctionData);

服务器页面可以编写csv或xls文件，但由于每秒会发布一次大量数据，因此使用mySQL数据库可能会更明智。

保存到csv文件以在Excel中打开是最简单的方法，但我认为您不能用GreaseMonkey保存文件：我认为最简单的方法是将文件存储在远程服务器上。。。只是仍然有点不确定如何继续…引用“那么，比如说，你已经分析了数据并确定你想要这些列：列索引含义/目的--------------------------------------------4拍卖展示编号5拍卖ID 8当前价格9高价竞标者ID 10剩余时间12到？？？”？？？" . 是的，这就是我的想法……：）但我的存储次数会减少，而不是每秒钟。我感兴趣的信息是：拍卖展示编号。开始出价，结束出价。这将大大减少数据量，因为它不会每秒都保存数据。您提到我可以将数据存储在自己的机器上……但我需要XAMPP）。请详细说明它是什么，以及我如何在我的机器上安装/实现它？它是如何工作的？我第一次访问它时：）@Brock，如果我不是每秒都存储数据，而是只有在拍卖结束时，我才会这样做：`$AuctionData=json\u decode（$HTTP\u RAW\u POST\u data）；打印（$AuctionData）；'如果拍卖结束是真的。。。正确的？“不是每一秒。”布罗克说。好的，谢谢，找到了XAMPP。我还得到了64位Win7。找到这篇文章：，所以我会试试。@Ludwig，你不需要XAMPP，你需要任何服务器技术，如Coldfusion、PHP、Python、Java、.net等。XAMPP只是一种快速启动和运行流行免费服务器（PHP）的方法。如果您以前从未编写过web应用程序，那么您将有一段学习曲线。。。请注意，如果您不熟悉PHP调试，那么初学者PHP代码将不会执行任何可见操作。。。是的，您和您的脚本完全负责调用

GM\u xmlhttpRequest

的频率。（不必是每秒一次。）

$AuctionData = json_decode($HTTP_RAW_POST_DATA);
print_r ($AuctionData);
