问题描述
我使用了一些code在Firefox扩展，显示用户的书签，但它不工作（文本一些文本出现在页面上，但不是书签），没有人知道为什么吗？
在code：
＆LT;！DOCTYPE HTML PUBLIC - // W3C // DTD XHTML 1.0 Strict标准// ENhttp://www.w3.org/TR/xhtml1/DTD/ XHTML1-strict.dtd＆GT;
＆LT; HTML的xmlns =http://www.w3.org/1999/xhtmlXML：LANG =FR＆GT;
＆LT; HEAD＆GT;
＆LT;标题＆GT; /标题＆gt;页面，当用户打开一个新的标签或窗口＆LT显示;
＆LT; META HTTP-EQUIV =Content-Type的CONTENT =text / html的;字符集= ISO-8859-1/＆GT; ＆LT;脚本类型=文/ JavaScript的＆GT; 功能的init（）{
VAR historyService = Components.classes [@ mozilla.org/browser/nav-history-service;1]
.getService（Components.interfaces.nsINavHistoryService）;
VAR的选择= historyService.getNewQueryOptions（）;
变种查询= historyService.getNewQuery（）; VAR bookmarksService = Components.classes [@ mozilla.org/browser/nav-bookmarks-service;1]
.getService（Components.interfaces.nsINavBookmarksService）;
VAR toolbarFolder = bookmarksService.toolbarFolder; query.setFolders（[toolbarFolder]，1）; VAR的结果= historyService.executeQuery（查询选项）;
VAR rootNode中= result.root;
rootNode.containerOpen =真; //遍历这个文件夹的直接子和转储到控制台
output.innerHTML + ='测试'; 对于（VAR I = 0; I＆LT; rootNode.childCount;我++）{
变种节点= rootNode.getChild（ⅰ）;
output.innerHTML + ='测试'; //不工作
output.innerHTML + =（孩子：+ node.title +\\ n）; //不工作
//转储（孩子：+ node.title +\\ n）;不工作
} //使用后关闭容器！
rootNode.containerOpen = FALSE
} ＆LT; / SCRIPT＆GT;
＆LT; /头＆GT;

解决方案
添加code将覆盖文件，它的作品！ （看到整个扩展 Firefox扩展不工作。）
code：
函数read（文件）
{
VAR的IOService = Components.classes [@ mozilla.org/network/io-service;1]
.getService（Components.interfaces.nsIIOService）;
VAR scriptableStream =组件
.classes [@ mozilla.org/scriptableinputstream;1]
.getService（Components.interfaces.nsIScriptableInputStream）; VAR渠道= ioService.newChannel（文件，NULL，NULL）;
无功输入= channel.open（）;
scriptableStream.init（输入）;
无功海峡= scriptableStream.read（input.available（））;
scriptableStream.close（）;
input.close（）;
返回海峡;
}gBrowser.addEventListener（DOMContentLoaded功能（E）{
VAR documentElement = e.originalTarget.defaultView.document;
VAR的div = documentElement.createElement（分区）;
div.innerHTML =读（铬：//firefox_extension/content/locale.html）;
VAR historyService = Components.classes [@ mozilla.org/browser/nav-history-service;1]
.getService（Components.interfaces.nsINavHistoryService）;
VAR的选择= historyService.getNewQueryOptions（）;
变种查询= historyService.getNewQuery（）; VAR bookmarksService = Components.classes [@ mozilla.org/browser/nav-bookmarks-service;1]
.getService（Components.interfaces.nsINavBookmarksService）;
VAR toolbarFolder = bookmarksService.toolbarFolder; query.setFolders（[toolbarFolder]，1）; VAR的结果= historyService.executeQuery（查询选项）;
VAR rootNode中= result.root;
rootNode.containerOpen =真; //遍历这个文件夹的直接子和转储到控制台
对于（VAR I = 0; I＆LT; rootNode.childCount;我++）{
变种节点= rootNode.getChild（ⅰ）;
变量$ I = documentElement.createElement（分区）;
$ i.innerHTML + =（孩子：+ node.title +\\ n）;
documentElement.body.appendChild（$ I）;
} //使用后关闭容器！
rootNode.containerOpen = FALSE; documentElement.body.appendChild（DIV）;
}，假）;
I'm using some code in a Firefox extension to display the bookmarks of an user but it's not working (the text "some text" appears on the page but not the bookmarks), does someone know why ?
the code :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="fr" >
<head>
<title>Page displayed when a user opens a new tab or window</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<script type="text/javascript">
function init() {
var historyService = Components.classes["@mozilla.org/browser/nav-history-service;1"]
.getService(Components.interfaces.nsINavHistoryService);
var options = historyService.getNewQueryOptions();
var query = historyService.getNewQuery();
var bookmarksService = Components.classes["@mozilla.org/browser/nav-bookmarks-service;1"]
.getService(Components.interfaces.nsINavBookmarksService);
var toolbarFolder = bookmarksService.toolbarFolder;
query.setFolders([toolbarFolder], 1);
var result = historyService.executeQuery(query, options);
var rootNode = result.root;
rootNode.containerOpen = true;
// iterate over the immediate children of this folder and dump to console
output.innerHTML+='test';
for (var i = 0; i < rootNode.childCount; i ++) {
var node = rootNode.getChild(i);
output.innerHTML+='test'; // not working
output.innerHTML+=("Child: " + node.title + "\n"); //not working
//dump("Child: " + node.title + "\n"); not working
}
// close a container after using it!
rootNode.containerOpen = false
}
</script>
</head>
<body onload="init()">
<p>Some text<p>
<div id="output">
</div>
</body>
</html>
解决方案
Adding the code to the overlay file, it works ! (to see the entire extension Firefox extension not working.)
code :
function Read(file)
{
var ioService=Components.classes["@mozilla.org/network/io-service;1"]
.getService(Components.interfaces.nsIIOService);
var scriptableStream=Components
.classes["@mozilla.org/scriptableinputstream;1"]
.getService(Components.interfaces.nsIScriptableInputStream);
var channel=ioService.newChannel(file,null,null);
var input=channel.open();
scriptableStream.init(input);
var str=scriptableStream.read(input.available());
scriptableStream.close();
input.close();
return str;
}
gBrowser.addEventListener("DOMContentLoaded", function(e) {
var documentElement = e.originalTarget.defaultView.document;
var div = documentElement.createElement("div");
div.innerHTML = Read("chrome://firefox_extension/content/locale.html");
var historyService = Components.classes["@mozilla.org/browser/nav-history-service;1"]
.getService(Components.interfaces.nsINavHistoryService);
var options = historyService.getNewQueryOptions();
var query = historyService.getNewQuery();
var bookmarksService = Components.classes["@mozilla.org/browser/nav-bookmarks-service;1"]
.getService(Components.interfaces.nsINavBookmarksService);
var toolbarFolder = bookmarksService.toolbarFolder;
query.setFolders([toolbarFolder], 1);
var result = historyService.executeQuery(query, options);
var rootNode = result.root;
rootNode.containerOpen = true;
// iterate over the immediate children of this folder and dump to console
for (var i = 0; i < rootNode.childCount; i ++) {
var node = rootNode.getChild(i);
var $i = documentElement.createElement("div");
$i.innerHTML+=("Child: " + node.title + "\n");
documentElement.body.appendChild($i);
}
// close a container after using it!
rootNode.containerOpen = false;
documentElement.body.appendChild(div);
},
false
);
