I have one page with list of reports and after clicking on report it redirects me to internal report page in new tab with:
window.open(reportIdUrl,reportId);
So when i am back on report list and i want to open same report i will use
window.open("",reportId);
if(redirect.location.href === "about:blank" || redirect.location.href !== '<internalreportpage>') {
redirect = window.open(reportUrl,reportId);
redirect.focus();
} else {
redirect.focus();
}
But when someone from new tab with internal report page navigates somehow to report list page (within this tab) and then tries to open internal report page it will open it in same tab as it is tab reference not content reference.
Does anybody know some way to drop reference when i access if condition?
Something like:
window.open("",reportId);
if(redirect.location.href === "about:blank" || redirect.location.href !== '<internalreportpage>') {
window.dropReference(reportId) //change_me
redirect = window.open(reportUrl,reportId);
redirect.focus();
} else {
redirect.focus();
}
So it will create new tab with new reportId reference?
Thanks
EXAMPLE
--reportlistpage
linkToReport1 (window.open(report1Url,1))
linkToReport2 (window.open(report2Url,2))
.

You click on linkToReport1 - 2 tabs are opened. One with reportlistpage and one with internal-report/report1.
You go back to parent tab and click to linkToReport1. Tab is opened with reference to "1" and will focus to it and no new tab is opened (this is ok).
You are on linkToReport1 and you redirect with some menu hyperlink to reportlistpage (within linkToReport1 tab). Url changed to /report-list
You click to linkToReport1. Nothing happen (this is not ok) because you are on the tab with reference to 1 (content and url changed), now you want to open a new tab with /internal-report/report1 url and store it as 1 with window references.
I figured it out. It is bit simple when you realize you can set or reset window.name. So there is nothing like references from parent.
Based on content you can do something following. In the page you want to keep track in tab,
at the beginning (in my case internalReport id):
var currentWindow = window.self;
currentWindow.name = reportId; //this is in case someone manually opened it without window.open(internalReportUrl, reportId)
then bind resetting of window.name on beforeunload event (e.g.):
var resetWindowName = function() {
var currentWindow = window.self;
currentWindow.name = ""
}
window.addEventListener('beforeunload', resetWindowName);
So when you redirect from internalreportpage somewhere, name is cleared and you can repeadetly call
window.open(internalReportUrl,reportId)
which will open new tab for you.

I have a question about the new tab for the link.
Is there anyway I can set the browser tab title before user clicks a link? It seems like there is no way to debate the title for the new tab if the html contained in the new tab doesn't have title attribute. Am I right? How do I set the title?
//the href is dynamic so I can't set them one by one because I have 100+ html file here
<a href="test.html" target="_blank">open me<a>
As you have it, this is not possible because your links are just normal HTML links. When the new page opens in a new tab, the current page will not have any reference to it and so cannot change it in any way. You will need to open the page using javascript and set the title that way.
You can dynamically set this up in window onload to find all a tags and add a click event whihc opens the window and sets the title.
If you want different titles for each page, you can store this in a data- attribute in the a tag.
Note tho that this will only work with pages in the same domain (for security), and that it does not handle people right clicking and pressing "Open in New Window". Middle click in Windows does seem to work however.
HTML
open me
JavaScript
window.addEventListener("load", function() {
// does the actual opening
function openWindow(event) {
event = event || window.event;
// find the url and title to set
var href = this.getAttribute("href");
var newTitle = this.getAttribute("data-title");
// or if you work the title out some other way...
// var newTitle = "Some constant string";
// open the window
var newWin = window.open(href, "_blank");
// add a load listener to the window so that the title gets changed on page load
newWin.addEventListener("load", function() {
newWin.document.title = newTitle;
});
// stop the default `a` link or you will get 2 new windows!
event.returnValue = false;
}
// find all a tags opening in a new window
var links = document.querySelectorAll("a[target=_blank][data-title]");
// or this if you don't want to store custom titles with each link
//var links = document.querySelectorAll("a[target=_blank]");
// add a click event for each so we can do our own thing
for(var i = 0; i < links.length; i++) {
links[i].addEventListener("click", openWindow.bind(links[i]));
}
});
Sample JsFiddle
You can pass the title with hash and get it on another page, if this another page is yours and you can modify its code.
1st page:
...
<a href="test.html#the_title_you_want" target="_blank">open me<a>
...
2nd page - modify the body opening tag like this:
<body onload="document.title=window.location.hash.replace('#','');">
If the page you are linking to isn't yours, you can use window.open method:
open me
I have not seen addEventListener work reliably, especially when opening a new page using javascript. The best way to change the tab title and have it work reliably is to set a timeout until the page loads. You may have to play with the timeout value, but it works.
var newWindow = window.open(url, '_blank');
setTimeout(function () {
newWindow.document.title = "My Tab Name";
}, 100);
You have two options. Using pure HTML, you can let the user open up links, then later on change the title. Or you can change the title with inline JavaScript. Here's how you do both:
Method 1
Change your links by assigning a target attribute, and then later on use that window name to control the document. For instance in your links it would be: <a href="whatever" target="theNewWindow">. Whenever you want to change the title for this page, you'd use JavaScript as such: window.open("", "theNewWindow").document.title = "New Page Title!"; The problem with this method however is that all links with that target/window name will open in that same window. In addition, after the first time the link is clicked, your browser won't automatically switch to the new tab/window.
Method 2
Change your links by assigning an onclick attribute, which would open the link manually and change the title of the page immediately. Basically it would come down to look like: <a href="whatever" onclick="var w=window.open(this.href, '_blank'); (w.onload=function(){w.document.title='New Page Title!';})(); return false;">. This opens the window based on the href attribute, immediately changes the title, and sets the window to change the title to that when it finishes loading (just in case there really was a title tag).
The problem with both of these methods (as mentioned by others) is your html files have to be on the same domain.
The simplest way is a follows:
var winTab = window.open("", "_blank")
//Open URL by writing iframe with given URL
winTab.document.write("write iframe with your url in src here")
//Set Title for the new tab
winTab.document.title = "Form Title"
You could make your own Page 2 that opens up the other pages (the ones you can't edit), in a frameset. You can then either change the title dynamically when loading your page 2, or as others have suggested if you use window.open you can control the title from the parent page.
If you are in page 1, and opening page 2 in a new tab, you can't set title for page 2 from page 1.
If you have access to page 2 then it's possible, otherwise not.
In my extension I want to open a new tab when a toolbar button is clicked (works), display a static HTML page with JavaScript on the tab (works) and pass data (URL from the originating page) to the new tab (does not work). I tried:
Using query parameters like myTab.url = safari.extension.baseURI + 'page.html?' + params, but the target page does not seem to have a location assigned (location.search giving no result).
myTab.page.dispatchMessage("url", "someUrl"); after opening the tab, but the message never arrives in the new tab (I suspect, it's already "through", when the tab has opened).
Any suggestions?
I parsed document.URL in opened page for specific parameter and it worked for me. E.g.
function __onLoad()
{
var p = $.url(document.URL);
alert(p.param("url"));
}
And two possible reasons for missed message:
You did not add message event listener on your page
You called dispatchMessage before event listener was added

I have a link on my site that opens a new window to a page that plays a very long audio file. My current script works fine to open the page and not refresh if the link is clicked multiple times. However, when I have moved to a seperate page on my site and click this link again, it reloads. I am aware that when the parent element changes, I will lose my variable and thus I will need to open the window, overiding the existing content. I am trying to find a solution around that. I would prefer not to use a cookie to achieve this, but I will if required.
My script is as follows:
function OpenWindow(){
if(typeof(winRef) == 'undefined' || winRef.closed){
//create new
winRef = window.open('http://samplesite/page','winPop','sampleListOfOptions');
} else {
//give it focus (in case it got burried)
winRef.focus();
}
}
You should first to call winRef = window.open("", "winPopup") without URL - this will return a window, if it exists, without reloading. And only if winRef is null or empty window, then create new window.
Here is my test code:
var winRef;
function OpenWindow()
{
if(typeof(winRef) == 'undefined' || winRef.closed)
{
//create new
var url = 'http://someurl';
winRef = window.open('', 'winPop', 'sampleListOfOptions');
if(winRef == null || winRef.document.location.href != url)
{
winRef = window.open(url, 'winPop');
}
}
else
{
//give it focus (in case it got burried)
winRef.focus();
}
}
It works.
Thanks to Stan and http://ektaraval.blogspot.ca/2011/05/how-to-set-focus-to-child-window.html
My solution creates a breakout pop-up mp3 player that remains active site wide and only refreshes if the window is not open prior to clicking the link button
function OpenWindow(){
var targetWin = window.open('','winPop', 'sample-options');
if(targetWin.location == 'about:blank'){
//create new
targetWin.location.href = 'http://site/megaplayer';
targetWin.focus();
} else {
//give it focus (in case it got burried)
targetWin.focus();
}
}
Like you said, after navigating away from original page you're losing track of what windows you may have opened.
As far as I can tell, there's no way to "regain" reference to that particular window. You may (using cookies, server side session or whatever) know that window was opened already, but you won't ever have a direct access to it from different page (even on the same domain). This kind of communication between already opened windows may be simulated with help of ajax and server side code, that would serve as agent when sharing some information between two windows. It's not an easy nor clean solution however.
I have a page (let's say page1) that open the page2 using:
showModalDialog(page2, '', 'dialogWidth:55em; dialogHeight:50em; status:0');
I am facing 2 problems (in this post i am going to write the first one):
1) when i want to close the second page using javascript code it always asks me that the page is trying to close itself do i want to allow that or no. I want to force close it without asking me anything. I have tried the following:
function CloseSelection(id) {
window.opener = "page1"
window.returnValue = id;
window.close();
}
And in the Form tag target="_self". But nothing happened, the popup keeps on showing.
can anyone help me please?
You dont need to set the window.opener as it is set by default to the object of opener page.
On Page2 the code will be:
function CloseSelection(id) {
window.returnValue = id;
window.close();
}
On Page1
var returnVal = showModalDialog("page2.html", '', 'dialogWidth:55em; dialogHeight:50em; status:0');
// here returnVal will contain the data which is return by page2
Hope it helps.
You can not force the window to open in a new window. It might work in some browsers but not all.
In order to close a window you can do this:
// open
var win = window.open("someurlgoeshere");
// close
win.close();
I believe you only get the "are u sure you wish the leave this page" message if the window itself tries to close itself (window.close())
I have a page A which opens a javascript window as myWin = window.open(..). Now in another page B in the same domain, when user clicks on a link, I want to check if myWin is available, if yes then bring that window in front, else do a new myWin.
The problem I have is the window.js file in both pages and window.js contains the line
var myWin = null;
Within Page A scope, my logic works and brings window to front. Within Page B it works as well. Howver when I open window in Page A, click on link in Page B, it fails.
It is as if myWin is reset to null in scope of Page B. How can I overcome this problem? Pointers??/
The popup window is created by page A and only page A contains a reference to that window. When you open page B, there is no way to pass page A's reference to the popup over to page B. This cannot be done.
You want to call window.open with an empty url, e.g.
var newWindow = window.open('', title, dimension); // title needs to be a constant
if (newWindow.location.href && newWindow.location.href!='about:blank') {
// Window was already open and points to something
newWindow.focus();
} else {
// new window make it point to something
newWindow.location.href = 'http://yoursite';
}
This assumes that the popup is opening a window within the same site as the calling page, since otherwise you can encounter various permissions issues.
