CHROME插件 “复制选中的链接地址”
昨日本来在人人影视上面下载美剧，结果那部电视剧太多集了。CHROME下那个复制全部不能用。只好自己写一个。
代码如下:
注册文件 manifest.json
{
"name": "复制选中的链接地址",
"description": "复制选中的链接地址到剪贴板中(电驴，离线什么的)",
"version": "0.1",
"permissions": ["contextMenus","tabs","https://*/*","http://*/*"],
"background_page": "background.html"
}
实现选中链接文件（之前对CHROME也没有什么了解，临时从chrome API那里下载的一个例子,文件名忘改了） sample.js
var selection = window.getSelection();
if(selection.rangeCount > 0)
{
var range = selection.getRangeAt(0);
var div = document.createElement('div');
//把复制的内容放入div中，转化为DOM结构
div.appendChild(range.cloneContents());
var contents = "";
//获取div里面的，链接元素
var aucher_list = div.getElementsByTagName("a");
for (var i = 0; i < aucher_list.length; i++) {
contents += "\n" + aucher_list[i].href;
}
contents = contents.substring(1);
//向background发送ED2K链接
chrome.extension.sendRequest({text:contents});
}
background.js
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<title>Background</title>
<script type="text/javascript" charset="utf-8">
chrome.extension.onRequest.addListener(function (msg, sender, sendResponse) {
var textarea = document.getElementById("lnktext");
textarea.value = msg.text;
textarea.select();
document.execCommand("copy", false, null);
sendResponse({});
}
);
function copylinkbyselected(info,tab){
chrome.tabs.executeScript(null, { "file" : "sample.js", "allFrames" : true } );
}
chrome.contextMenus.create(
{
"title": "copy link by selected",
"contexts":["selection"],
"type":"normal",
"onclick": copylinkbyselected
});
</script>
</head>
<body>
<textarea id="lnktext" rows="8" cols="40"></textarea>
</body>
</html>
