问题描述
我已经编写了一些代码来显示我在IE8中的收藏夹但由于未知原因我在屏幕上没有输出，尽管我的页面被IE接受并且显示测试文本'这是一个测试' 。
I've written some code to display my favorites in IE8 but for an unknown reason I have no output on the screen despite the fact that my page is accepted by IE and that the test text 'this is a test' is displayed.
我的代码：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso 8859-1" />
<script type="text/javascript">
var i = 0;
var favString = "";
var fso;
function GetFavourites(Folder) {
var FavFolder = fso.GetFolder(Folder);
//Gets Favourite Names & URL's for given folder.
var files = new Enumerator(FavFolder.Files);
for (; !files.atEnd(); files.moveNext()) {
var fil = files.item();
if (fil.Type == "Internet Shortcut") {
var textReader = fso.OpenTextFile(fil.Path, 1, false, -2);
var favtext = textReader.ReadAll();
var start = favtext.indexOf("URL", 16);
var stop = favtext.indexOf("\n", start);
favString += fil.Name.replace(/.url/, "");
favString += ":URL:";
//to separate favourite name & favorite URL
favString += favtext.substring(start + 4, stop - 1);
favorites.innerHTML += favString; // Not working !
favorites.innerHTML += 'test'; // Not working too !
favString += ":NEXT:"; //to separate favorites.
i++;
}
}
//Checks any subfolder exists
var subfolders = new Enumerator(FavFolder.SubFolders);
for (; !subfolders.atEnd(); subfolders.moveNext()) {
var folder = subfolders.item();
GetFavourites(folder.Path);
}
}
function Import() {
try {
fso = new ActiveXObject("Scripting.FileSystemObject");
if (fso !== null) {
//Create windows script shell object to access Favorites folder in user system.
var object = new ActiveXObject("WScript.Shell");
var favfolderName = object.SpecialFolders("Favorites");
if (favString === "") {
GetFavourites(favfolderName);
}
}
}
catch (err) {
alert("Security settings to be modified in your browser ");
}
}
</script>
</head>
<body onload="Import()">
<p>this is a test</p> <!-- Working ! -->
<div id="favorites">
</div>
</body>
</html>
推荐答案
以下适用于我：
var fso, favs = [];
function GetFavourites(Folder) {
var FavFolder = fso.GetFolder(Folder);
//Gets Favourite Names & URL's for given folder.
var files = new Enumerator(FavFolder.Files);
for (; !files.atEnd(); files.moveNext()) {
var fil = files.item();
if (fil.Type == "Internet Shortcut") {
var textReader = fso.OpenTextFile(fil.Path, 1, false, -2);
var favtext = textReader.ReadAll();
var start = favtext.indexOf("URL", 16);
var stop = favtext.indexOf("\n", start);
favString = fil.Name.replace(/.url/, "");
favString += ":URL:";
//to separate favourite name & favorite URL
favString += favtext.substring(start + 4, stop - 1);
favs.push(favString);
}
}
//Checks any subfolder exists
var subfolders = new Enumerator(FavFolder.SubFolders);
for (; !subfolders.atEnd(); subfolders.moveNext()) {
var folder = subfolders.item();
GetFavourites(folder.Path);
}
}
function Import() {
try {
fso = new ActiveXObject("Scripting.FileSystemObject");
if (fso !== null) {
//Create windows script shell object to access Favorites folder in user system.
var object = new ActiveXObject("WScript.Shell");
var favfolderName = object.SpecialFolders("Favorites");
if (favString === "") {
GetFavourites(favfolderName);
}
}
}
catch (err) {
alert("Security settings to be modified in your browser ");
}
}
请注意，我改变的只是元素的输出到名为的数组。我还删除了 i 变量，因为它没有被使用。运行脚本后，我在开发人员工具控制台中检查了该数组，它包含了我所有的收藏夹。
Note that all I changed was the output from an element to an array named favs. I also removed the i variable, because it wasn't used. After running the script, I checked the array in the developer tools console and it contained all my favourites.
