修改油脂猴子中URL的脚本 [英] Script to modify a URL in greasemonkey

问题描述

我正在尝试更改以下网址:

I'm trying to change the following url:

http://www.example.net/?image=full&action=view&imageid=1361 

进入

http://www.anothersite.com/download&id=1361&thumb=0

保留ID(在示例中为1361)

while preserving the id (1361 in the example)

(将"example.net/?image=full&action=view&image"更改为"anothersite.com/download&"，并在网址末尾添加& thum = 0")

(change 'example.net/?image=full&action=view&image' to 'anothersite.com/download&' and add '&thumb=0' at the end of the url)

如何为此编写GreaseMonkey脚本?

How do I write a GreaseMonkey script for that?

ps.我已经用谷歌搜索并复制了下面的代码.它可以正常工作，但问题是它也向其他链接添加了& thum = 0"(不仅是已替换"的链接)

ps. I've already googled it and copied the code below. It's working, but the problem is it adds '&thumb=0' to the other link too (not just the 'replaced' link(s))

// ==UserScript==
// @name        whatever
// @namespace   lii
// @description redirect to anothersite
// @include     http://www.example.net/?image=full&action=view*
// @version     1
// @grant       none
// ==/UserScript==

var links,thisLink;
links = document.evaluate("//a[@href]",
    document,
    null,
    XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,
    null);

for (var i=0;i<links.snapshotLength;i++) {
    var thisLink = links.snapshotItem(i);

    thisLink.href = thisLink.href.replace('http://www.example.net/?image=full&action=view&image',
                                          'http://www.anothersite.com/download&')  + "&thumb=0";

}

推荐答案

尝试一下:

thisLink.href = thisLink.href.replace(RegExp('http://www\\.example\\.net/\\?image=full&action=view&image(.*)'),
                                      'http://www.anothersite.com/download&$1&thumb=0');

它应用正则表达式来匹配URL，并提取ID，并将其作为$1插入到结果字符串中.

It applies regular expression to match the URL and extract the id and inserts it as $1 into the resulting string.
