请看下面的代码。

我希望能够搜索一个网页，其中将包含以下代码，或非常相似的代码。

<table class="fightTable"><tbody><tr><td class="fightClass"><a href="/profile.php?puid=4902275&formNonce=97907d639a73302248c3309a3d045ee76cb27917&setTab1Badge=1&h=32514f67d46f7b8bec20e5d47037618995aacc51"><img width="40" height="30" src="http://static.storm8.com/zl/images/vampire.png?v=330"></img></a></td><td class="fightMobster"><div><a href="/profile.php?puid=4902275&formNonce=97907d639a73302248c3309a3d045ee76cb27917&setTab1Badge=1&h=32514f67d46f7b8bec20e5d47037618995aacc51">

基本上，我需要创建一个脚本，将搜索页面的某些文本，在这种情况下，它将是彼得·潘。

一旦找到，在上面的代码中有一个链接，在最后，标记为"攻击"。我要创建的脚本，需要点击这个"攻击"链接只有当被搜索的文本被发现。

在这方面我还是个新手。但我认为这是可能通过DOM遍历?有人能告诉我怎么做吗?或者提供一个脚本片段，这将有助于我?非常感谢。:)

所以我创建了下面的;

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<script>
var results = [];
var links = document.getElementsByTagName('a');
for(var i = 0; i < links.length; i++)
if(links[i].innerText.trim() === 'PETER PAN')
    results.push(links[i]);
    </script>
</head>
<body>
<a href="http://www.google.com">PETER PAN</a>
</body>
</html>

但它实际上什么都不做?它只是加载了一个带有彼得潘链接的页面?我如何定位彼得潘文本，然后在我发布的原始代码中点击"攻击"链接?谢谢。

查找所有<a>标签，您可以这样做:

var results = [];
var links = document.getElementsByTagName('a');
for(var i = 0; i < links.length; i++)
    if(links[i].innerText.trim() === 'PETER PAN')
        results.push(links[i]);

然后你可以检查结果的长度，以知道是否找到了文本(如果你只需要一个结果，你可以中断for循环);

编辑给攻击链接id属性如下:

<a id="attack" onclick="return fsb82308759();" href="/hitlist.php?tab=fight.php&action=fight&hitlistId=82308759&formNonce=97907d639a73302248c3309a3d045ee76cb27917&h=284e4fe4946e6fb8af3a662f4583454eebc8bd23"><div class="fightActionInner"><div class="fightActionInnerInner">
Attack
</div></div></a>

然后在js中(在搜索结果的脚本下):

var attackLink = document.getElementById('attack');
if(results.length > 0)
    attackLink.click();
