我实际上正在开发我的第一个 Chrome 扩展程序,我需要改进一些功能。实际上我是 chrome 扩展的新手,不知道如何管理标签。
实际上,该扩展程序会打开一个弹出窗口,其中包含从远程网页捕获的链接列表。每个链接都会打开一个新选项卡,其中包含正确的内容。
我的目标是打开一个选项卡,并且对于每个链接,使用该单个选项卡(如果创建的选项卡已关闭,我可以打开一个新选项卡并继续使用它)。我想我可以创建一个新选项卡并通过分配的 ID 引用它,但我无法弄清楚如何真正编写正确的代码。
以下是涉及的代码:
popup.html
<!doctype html>
<html>
<head>
<title>NGI Little Helper - Subscribes</title>
<link rel="stylesheet" href="popup.css">
<!-- JavaScript and HTML must be in separate files for security. -->
<script type="text/javascript" src="common/jquery.js"></script>
<script type="text/javascript" src="popup.js"></script>
</head>
<body>
<h1>Topics</h1>
<div id="content">..:: Loading ::..</div>
</body>
</html>
popup.js
$.get("http://gaming.ngi.it/subscription.php?do=viewsubscription", function(data) {
var TDs = $('td[id^="td_threadtitle_"]', data);
$(document).ready(function() {
$("#content").html("<br/>");
$.each( TDs, function() {
//Removes useless elements from the source
$('img[src="images/misc/tag.png"]', this).remove();
$('span', this).remove(); //$('span[class="smallfont"]', this).remove();
$('div[class="smallfont"]', this).remove();
$('img[src="images/buttons/firstnew.gif"]', this).attr('src', '/img/icons/comment.gif');
$('a[style="font-weight:bold"]', this).removeAttr("style");
//Modify the lenght of the strings
if ($("a[id^='thread_title_']", this).text().length > 35) {
$("a[id^='thread_title_']", this).text( $("a[id^='thread_title_']", this).text().substring(0, 30) + " [...]" );
}
//Modify the URL from relative to absolute and add the target="_newtab"
$("a[id^='thread_']", this).attr('href', "http://gaming.ngi.it/"+ $("a[id^='thread_']", this).attr('href'));
$("a[id^='thread_']", this).attr('target', "_newtab");
//Send the HTML modified to the popup window
$("#content").html($("#content").html() + $('div', this).wrap("<span></span>").parent().html() +"<br/>" );
});
});
});
清单.json
{
"name": "NGI Little Helper",
"version": "0.8.5",
"manifest_version": 2,
"description": "Extension per gli Utenti del forum gaming.ngi.it",
"options_page": "fancy-settings/source/index.html",
"background": {
"page": "background.html"
},
"icons": {
"16": "img/logo16.png",
"48": "img/logo48.png",
"128": "img/logo128.png"
},
"content_scripts": [{
"matches": ["*://gaming.ngi.it/*"],
"js": ["common/jquery.js", "logo_changer/logo_change.js"],
"run_at": "document_start"
}],
"browser_action": {
"default_icon": "img/icon.png",
"default_popup": "popup.html",
"default_title": "Visualizza Subscriptions"
},
"permissions": [
"*://gaming.ngi.it/*"
]
}
以下是一段 HTML 代码,将在所有操作后呈现到弹出窗口中。任何 div 都与此类似,除了链接当然会更改:
<div>
<a href="http://gaming.ngi.it/showthread.php?goto=newpost&t=555954" id="thread_gotonew_555954" target="_newtab"><img class="inlineimg" src="/img/icons/comment.gif" alt="Go to first new post" border="0"></a>
<a href="http://gaming.ngi.it/showthread.php?goto=newpost&t=555954" id="thread_title_555954" target="_newtab">[All Gamez] [Frozen Synapse] S [...]</a>
</div>
如果需要,我可以提供完整的源代码。
