在子窗口中跨域域，获得焦点。 [英] cross domain site in child window, get focus.
问题描述
1.我有两个链接，当用户点击链接时，子窗口打开并加载跨域URL。
如果用户再次单击它，我想通知用户或将焦点设置到已打开的窗口。我怎样才能做到这一点。我尝试在window.open函数调用中为窗口设置一个名称，但每当我尝试访问它时，它返回'' ACCESS IS DENIED ''
我尝试使用数组来存储已经打开的Windows网址，如果用户请求相同的网址，则会显示一条警告消息。但是我想将焦点设置到已经打开的窗口，用户正在请求。
2.父窗口关闭时如何关闭所有子窗口？
3.当用户关闭主窗口/浏览器时，如何触发注销按钮？
for the第一个问题我试过......
newWindowsArray = new 数组（ ）;
var scrwid = $（window）.width（）; var scrht = $（window）.height（）; var winhgt = scrht - 140 ; var winwdth = scrwid - 20 ;
函数OpenWindow（目标，名称）{
如果（checkItem（newWindowsArray，Target））{
openedWindow = window.open（目标，' _ blank'，' < span class =code-string> width =' + winwdth + ' ，height =' + winhgt + ' ，status = 0，toolbar = 0，menubar = 0，location = 0，scrollbars = 1 ，可调整大小= 1，screenX = 0，screenY = 170，顶部= 170，左= 10' ）;
newWindowsArray [newWindowsArray.length] =目标;
var intervalId = setInterval（function（）{
if （openedWindow.closed ）{
clearInterval（intervalId）;
if （newWindowsArray.length > 0 ）{
for （i = 0 ; i < newWindowsArray.length; i ++）{
removeItem（newWindowsArray，Target）;
break ;
}
}
}
}， 10 ）;
}
}
函数removeItem（array，item）{
if （array.length < span class =code-keyword>> 0 ）{
for （ var i in array）{
if （array [i] == item）{
array.splice（i， 1 ）;
break ;
}
}
}
}
function checkItem（array，item）{
if （array.length > 0 ）{
for （ var i in array）{
if （array [i] == item）{
alert（' 窗口已经打开！）; // 我想将焦点设置到打开的窗口。
return false ;
}
}
返回 true ;
}
其他 {
return 真;
}
}
第3个问题

window.onbeforeunload：function（）{触发按钮点击} //不工作.....
与...相同卸货功能。

1.I have two links, when ever user clicks on a link ,child window opens and loads the cross domain url.
If the user click it again,I want to notify user or set focus to the already opened window. How can I achieve this. I tried setting a name to the window in window.open function call, But whenever I try to access it, it return ''ACCESS IS DENIED''
I tried using an array to store already opened windows urls and if the user requests the same url, an alert message is shown. But I want to set focus to the already opened window, the user is requesting.
2.How to close all the child windows when parent window is closed?
3.How can I trigger logout button click when user closes the main window/browser?
for the first question I tried...
newWindowsArray = new Array();
var scrwid = $(window).width(); var scrht = $(window).height(); var winhgt = scrht - 140; var winwdth = scrwid - 20;
function OpenWindow(Target, Name) {
if (checkItem(newWindowsArray, Target)) {
openedWindow = window.open(Target,'_blank', 'width=' + winwdth + ',height=' + winhgt + ',status=0,toolbar=0,menubar=0,location=0,scrollbars=1,resizable=1,screenX=0,screenY=170,top=170,left=10');
newWindowsArray[newWindowsArray.length] = Target;
var intervalId = setInterval(function () {
if (openedWindow.closed) {
clearInterval(intervalId);
if (newWindowsArray.length > 0) {
for (i = 0; i < newWindowsArray.length; i++) {
removeItem(newWindowsArray, Target);
break;
}
}
}
}, 10);
}
}
function removeItem(array, item) {
if (array.length > 0) {
for (var i in array) {
if (array[i] == item) {
array.splice(i, 1);
break;
}
}
}
}
function checkItem(array, item) {
if (array.length > 0) {
for (var i in array) {
if (array[i] == item) {
alert('window already opened!');//I want to set focus to the opened window.
return false;
}
}
return true;
}
else {
return true;
}
}
for 3rd question:
window.onbeforeunload:function(){triggered button click}//not working.....
same with unload function.
any suggestion is appreciated..................
(window).width(); var scrht =
(window).height(); var winhgt = scrht - 140; var winwdth = scrwid - 20; function OpenWindow(Target, Name) { if (checkItem(newWindowsArray, Target)) { openedWindow = window.open(Target,'_blank', 'width=' + winwdth + ',height=' + winhgt + ',status=0,toolbar=0,menubar=0,location=0,scrollbars=1,resizable=1,screenX=0,screenY=170,top=170,left=10'); newWindowsArray[newWindowsArray.length] = Target; var intervalId = setInterval(function () { if (openedWindow.closed) { clearInterval(intervalId); if (newWindowsArray.length > 0) { for (i = 0; i < newWindowsArray.length; i++) { removeItem(newWindowsArray, Target); break; } } } }, 10); } } function removeItem(array, item) { if (array.length > 0) { for (var i in array) { if (array[i] == item) { array.splice(i, 1); break; } } } } function checkItem(array, item) { if (array.length > 0) { for (var i in array) { if (array[i] == item) { alert('window already opened!');//I want to set focus to the opened window. return false; } } return true; } else { return true; } }
