如何在Greasemonkey中替换链接的目标？ [英] How can you replace a link's target in Greasemonkey?

问题描述

我正在尝试在Greasemonkey中编写一个脚本，用其他东西替换链接的目标，但是由于我有限的Javascript知识，我真的不知道如何做到这一点。

I'm trying to write a script in Greasemonkey that will replace a link's target with something else, but with my limited Javascript knowledge I don't really know how to do this.

基本上我正在尝试查找包含特定字符串的所有链接（例如：// a [contains（@ href，'xx'）]），以及要么用另一个链接替换它们，要么添加一些东西（用'zyx987.com'替换'abc123.com'或用'abc123.com/folder'替换'abc123.com'）。

Basically I'm trying to find all links containing a certain string of characters (ex: //a[contains(@href, 'xx')] ), and either replace them with another link, or append something to them (replacing 'abc123.com' with 'zyx987.com' or 'abc123.com' with 'abc123.com/folder').

如果你能指出我正确的道路，我会非常感激。

If you could point me on the right path I'd greatly appreciate it.

编辑：这是工作代码以防将来某人有同样的问题：

edit: This is working code in case someone has the same question in the future:

var links,thisLink;
links = document.evaluate("//a[contains(@href, 'roarrr')]",
    document,
    null,
    XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,
    null);
for (var i=0;i<links.snapshotLength;i++) {
    var thisLink = links.snapshotItem(i);
    thisLink.href += 'test.html';
}

推荐答案

var links = document.evaluate("//a[contains(@href, 'roarrr')]", document, null, 
XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); 
for (var i=0; i < links.snapshotLength; i++) 
{ 
  var thisLink = links.snapshotItem(i); 
  thisLink.href += 'test.html'; 
}
