我们有一个 iPad 应用程序可以在我们的旧 iPad 上运行。
我们打开外部链接使用 var x = window.open(url)
在一天结束时,当用户关闭应用程序的这一部分时,我们遍历它打开的所有窗口并对每个窗口执行 x.close(),一切正常。
在装有 IOS 5 和可爱标签的新 iPad 上进行测试, 打开新窗口(尽管现在它们作为选项卡打开)很好,但是执行 x.close() 似乎不一定关闭 x,它可能会关闭窗口 y 或 z。执行 x.focus() 或 y.focus() 工作得很好,正确的选项卡成为焦点,但关闭似乎只是选择它想要的任何选项卡。
这是一个错误还是我做错了什么?示例程序:
<html>
<head></head>
<body>
<script>
//The openWindow array will hold the handles of all open child windows
var openWindow = new Array();
var win1;
var win2;
//Track open adds the new child window handle to the array.
function trackOpen(winName) {
openWindow[openWindow.length]=winName;
}
//loop over all known child windows and try to close them. No error is
//thrown if a child window(s) was already closed.
function closeWindows() {
var openCount = openWindow.length;
for(r=openCount-1;r>=0;r--) {
openWindow[r].close();
}
}
//Open a new child window and add it to the tracker.
function open1() {
win1 = window.open("http://www.yahoo.com");
trackOpen(win1);
}
//Open a different child window and add it to the tracker.
function open2() {
win2 = window.open("http://www.google.com");
trackOpen(win2);
}
//Open whatever the user enters and add it to the tracker
function open3() {
var newURL = document.getElementById("url").value;
var win3= window.open(newURL);
trackOpen(win3);
}
</script>
<input type="button" value="Open 1" onclick="open1()">
<input type="button" value="Open 2" onclick="open2()">
<input type="button" value="Focus 1" onclick="win1.focus()">
<input type="button" value="Focus 2" onclick="win2.focus()">
<input type="button" value="Close 1" onclick="win1.close()">
<input type="button" value="Close 2" onclick="win2.close()">
URL: <input type="text" id="url"> <input type="button" value="Open URL" onclick="open3()">
<input type="button" value="Close All" onclick="closeWindows()">
</body>
</html>
最佳答案
这对我有用(iPad 2 和 3;iOS 5.1.1 的 3)
var host=window.opener;
window.focus(); /* solves the iPad3 problem */
window.close(); /* the actual closing we want to achieve... */
/* makes the focus go back to opener on iPad2, fails silently on iPad3 */
try { host.focus(); } catch(e) {}
