</head>
<body>
<form>
<input type=button value="Open Windows" onclick="open_win()">
</form>
</body>
</html>
Thank you,

In most modern browsers you are not allowed to call window.open programatically, like through a setTimeout.
The browser will simply ignore the window.open statement if it is not inside a callstack that is initiated by a direct user interaction, for instance a mouse click event.
The reason for this is that it is very annoying behavior - you probably won't find a single person who enjoys using a site that opens windows by itself.
So: reconsider what you are trying to do, there is bound to be a better way - one where you can work with the browser/user and not against it/him/her :)
function open_win() {
window.open("x.com");
setTimeout("window.open('y.com')",60000);
setTimeout("window.open('z.com')",120000);
}
This should open x.com then after one minute y.com and after two it should open z.com.

I want to save some JavaScript code as a bookmark in chrome so it automatically opens my university login site and clicks on on the login button. I am completely inexperienced in JavaScript, so I have no clue how to do this. I snipped together the following code, which opens the correct website, but then does not click on anything. The first URL automatically puts me to the login site (third URL in the code) in case I have not logged in yet in this window.
(function() {
window.location.replace("https://lms.uzh.ch/auth/MyCoursesSite/0");
window.onload = function(){
if (current_url.startswith('https://lms.uzh.ch/auth/MyCoursesSite/0')) {
return;
}
if (current_url.startsWith('https://lms.uzh.ch/dmz/')) {
document.getElementById("wayf_submit_button").click();
}
};
})();
I'm sorry if this is too obvious a question and annoys any experts but as I said I am a complete beginner. I would of course add the "javascript:" at the beginning for chrome to understand the bookmark.
When you use window.location.replace, you change the address and you code can't work anymore.
I can suggest using some browser extension, your "click function" should work then.
I guess you could also try to make some simple html page with iframe, you call your "click function" at this page, but you target it to the iframe. After that you can change browser's location to the university's webpage as you should already be logged in.
<html>
<head>
</head>
<body>
<iframe src="your_university_address.com" id="some_id" onload="click_button()"></iframe>
<script>
function click_button()
{
my_iframe=document.getElementById('some_id');
my_iframe.contentDocument.getElementById('your_button_id').click();
}
</script>
</body>
</html>
Very simple but it should do that job.
(You can achieve similar result by using window.open() I guess)
I need JavaScript code or HTML to make two websites open in two new browser tabs when clicking on one link. I do not want them to open in new windows, or on the current page that the link is on.
It probably won't work because the browser might consider it a popup and block it.
If the user allows popups you can do:
window.open(url, '_blank');
Like:
<a id="mydoublelink" href="http://site1.com" target="_blank">foo</a>
document.getElementById("mydoublelink").onclick=function(){
window.open('http://site2.com', '_blank');
}
If you call window.open in the onclick event you should be fine. Built-in popup blockers allow those. The kind of popups that get blocked come from other events or from scheduled events like a setTimeout.
document.getElement("my_link").onclick = function () {
window.open(/*..*/); // works
}
document.getElement("my_link").onclick = function () {
setTimeout(function () {
window.open(/*..*/); // will probably get blocked
});
}
This means, for instance, that if you open a popup after an AJAX call it will very likely get blocked. A workaround in this case is to open the popup right away and fill in the content later. This is outside the scope of this question but I feel like this is information that everyone should know.
Something like this?
<!DOCTYPE html>
<html>
<head>
<script>
function open_win()
{
window.open("URL");
open_win_two();
}
function open_win_two()
{
window.open("URL");
}
</script>
</head>
<body>
<a onclick="open_win()">luyfl</a>
</body>
</html>
Yu can try the new target _newtab:
blabla
It works in Firefox, don't know if it's supported in other browsers.

is it possible to use javascript or jquery to go to fullscreen on page load buy invoking "F11" key press
I guess you can use html5 fullscreen API
var element = document.getElementById("myDiv");
// Mozilla
video.mozRequestFullScreen();
// Webkit
video.webkitEnterFullScreen();
<html>
<head>
<script type="text/javascript">
function nWin() {
window.open( "http://www.google.com/", "myWindow", "fullscreen=1")
}
</script>
</head>
<body>
<form>
<input type="button" onClick="nWin()" value="FullScreen">
</form>
</body>
The short answer - yes. The long answer - it depends...
You can do a window.open() to open a new fullscreen window - however not to make the original one fullscreen. A downside of this is that most popup blockers today will prevent automatic window opening this way.
Another way is to provide a link on that landing page and bind the window.open function to an onclick event of this link. This should prevent the popup blocker issue and give you what you want.
In any case, you're left with an interaction from the user, which will be required in all scenarios.
I have a page with an iframe in it. Within the iframe, the default page runs some javascript to open a child window, login to an external service, then display some content from that external service back in the iframe.
My code works fine in Chrome and IE but in Safari and Firefox it does not. In those browsers the parent window seems to ignore that fact that the user is now logged in to the external service and displays their "Not logged in" message instead of the info that is supposed to display.
Here's the code for what I'm trying to do.
HTML (main page):
<iframe id="brief" name="brief" src="contents/somepage.php?var=WXYZ" width="962" height="600">
<p>Your browser does not support iframes.</p>
</iframe>
somepage.php
<html>
<head>
<script type="text/javascript">
window.onload = function()
{
var code = 'WXYZ';
var login = http://www.externalsite.com/brief/html.asp?/cgi-bin/service?msg=0048&usr=username&pwd=pass';
//OPEN CHILD WINDOW AND LOGIN USING VARIABLES ABOVE, THEN CLOSE WINDOW
childWindow=window.open(login,'','width=30,height=30,location=no');
var cmd = 'childWindow.close()';
setTimeout(cmd,2000);
//REDIRECT THIS IFRAME TO BRIEFING INFORMATION
var uri = 'http://www.externalsite.com/brief/html.asp?/cgi-bin/service?msg=0092&AID=NOSEND&MET=1&NTM=1&LOC='+code;
self.location.href=uri;
}
</script>
</head>
<body>
</body>
</html>
I have tried adjusting various setTimeout functions to try to delay certain aspects of the script to wait for something else to happen but it doesn't seem to help.
Is there some cross-browser problem with this code that I am missing?
Thanks
setTimeout(cmd,2000); is not going to block script execution for two seconds; rather, it sets up an event that will fire in approximately 2 seconds. Immediately after your call to setTimeout, the remaining parts of the script will execute:
// This happens right away
uri = 'http://www.externalsite.com/brief/html.asp?/cgi-bin/service?msg=0092&AID=NOSEND&MET=1&NTM=1&LOC='+code;
self.location.href = uri;
The fact that it works in any browser is just lucky timing. If you want the iframe to refresh after the popup closes, add that code to your callback (you don't need to and shouldn't use a string for your timer handler, by the way):
setTimeout(function() {
childWindow.close();
var uri = 'http://www.externalsite.com/brief/html.asp?/cgi-bin/service?msg=0092&AID=NOSEND&MET=1&NTM=1&LOC='+code;
self.location.href = uri;
}, 2000);
Even this solution won't work if the popup's content doesn't load within two seconds. The best solution is to have the popup close itself after loading. Then, you could detect when it closes and know that you're ready to reload your iframe. But if this is a third-party site that you don't have control over, you're probably stuck using a less-than-ideal solution like this.
JavaScript doesn't allow you to update window.location without triggering a reload. While I agree with this policy in principle (it shouldn't be possible to visit my website and have JavaScript change the location bar to read www.yourbankingsite.com,) I believe that it should be possible to change www.foo.org/index to www.foo.org/help.
The only reason I care about this is for bookmarking. I'm working on a photo browser, and when a user is previewing a particular image, I want that image to be the default if they should bookmark that page. For example, if they are viewing foo.org/preview/images0-30 and they click on image #15, that image is expanded to a medium-sized view. If they then bookmark the page, I want the bookmark URL to be foo.org/preview/images0-30/active15.
Any thoughts, or is there a security barrier on this one as well? I can certainly understand the same policy being applied here, but one can dream.
Sounds like you should check out Really Simple History. It's how Google (for example, Gmail) allows any page to be bookmarkable (and has history) but doesn't refresh the whole page.
As for the other side of things (having people visit your site then automatically popping up the correct image), I'd try checking window.location.hash once the page loads and firing events based on that.
You can add an anchor to the URL without reloading the page and pick that up with javascript:
location.href = '.../#' + imageId;
As mentioned, generally with ajaxy sites, you manipulate/check the hash part of the URL (window.location.hash) to determine this kind of activity.
The biggest issue is making sure to check against the hash in DOM-ready/window-load, as if the user clicked on a given image. This will work with browsers and bookmarks, but may hamper search indexing.
How about detecting on page load if the URL contains a hash, and if it does, directing them to the page you want them to go to?
You can add [Add to Favorites] button on the page.
Sample:
var urlAddress = "http://www.example.com/#image1";
var pageName = "Example Page Title - Image1";
function addToFavorites() {
if (window.external) {
window.external.AddFavorite(urlAddress, pageName);
} else {
alert("Sorry! Your browser doesn't support this function.");
}
}
Or use one of these jQuery plugins:
http://plugins.jquery.com/project/bookmark
http://plugins.jquery.com/project/jqbookmark
http://plugins.jquery.com/project/AddFavourite
http://plugins.jquery.com/project/jFav
http://plugins.jquery.com/project/jBookmarkEngine
AND / OR
Use URLs with hash at the end and load your content (images etc.) based on that hash value.
function onLoad() {
if (window.location.hash == "image1") {
// load image1
}
}
There are also lots for jQuery plugins for working with URL hash events, for example:
http://plugins.jquery.com/project/hashhistory
http://plugins.jquery.com/project/hashchange
There are also lots of non jQuery JavaScript libraries for that, for example:
http://code.google.com/p/reallysimplehistory/
