I've spent more than 5 hours on this, I'm trying to load a link on a popup window and after loading I want to print it.
so what I did is the following
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script>
function printer(){
var link = 'file:///C:\\page0339.swf';
w = window.open(link, "_blank", "location=1,scrollbars=1,menuBar=1,width=600, height=400");
w.onload = function() {
this.print();
this.close();
};
}
$(document).ready(function () {
$("#print").click(function () {
printer();
});
});
</script>
<input type ="button" id = "print" value = 'print' />
inside onload I've tried alert message and it shows up but both this.print();this.close(); are never called, and I didn't see any javascript error.
so How I can call print function inside onload??
Seems like attaching an onload after already opening the window is the wrong way to go. Instead of
w.onload = function() {
this.print();
this.close();
};
Have you tried this?
w.print();
w.close();

I am having anchor tag on my page. I like to trigger click event onload . This means I wanna open this Deep link for a React Native app "narvin://wallet" go to my app. The link is working if you manually click
<script type="text/javascript">
function startMyApp() {
document.location = 'narvin://wallet';
setTimeout(function () {
if (confirm('You do not seem to have Your App installed, do you want to go download it now?')) {
document.location = 'https://cafebazaar.ir/app/cab.snapp.passenger';
}
}, 300);
}
</script>
Try to start MyApp
, but not working onload page with this code :
<script type="text/javascript">
window.onload = function () {
document.getElementById("loader").onclick();
setTimeout(function () {
if (confirm('You do not seem to have Your App installed, do you want to go download it now?')) {
document.location = 'https://cafebazaar.ir/app/cab.snapp.passenger';
}
}, 3000);
};
</script>
OR
<script type="text/javascript">
window.onload = function () {
document.location = 'narvin://wallet';
setTimeout(function () {
if (confirm('You do not seem to have Your App installed, do you want to go download it now?')) {
document.location = 'https://cafebazaar.ir/app/cab.snapp.passenger';
}
}, 3000);
};
</script>
Your getElementById was returning a null because your script executes before the document is loaded. Window have to be called after all page content is loaded. You can use document.ready event instead of window.onload event
i have 2 sites, and i want to use javascriptpostMessage between them.
on my main site i write the following code in an emty html file :
<html>
<script>
window.addEventListener("message",listener_,false);
function listener_(event) {
console.log('ok!');
<html>
<script>
window.addEventListener("message",listener_,false);
function listener_(event) {
console.log('ok!');
//console.log(event);
//console.log(event.data);
}
</script>
</html>
and in other site that i want to call the postmessage from the i write the following code:
<script type="text/javascript">
window.onload = function() {
testfunction();
};
function testfunction(){
var childWin = window.open("http://my-main-site.com/indexjava2.html","child");
childWin = postMessage('message','*');
console.log(TipaltiIframeInfo.height);
}
</script>
but it doesn't work after a lot of tries. i mean
console.log('ok!'); or console.log(event); console.log(event.data);
doesn't trigger on console of main site,
what to do?
thanks
Aside from the fact that you've got a <script> and an <html> tag in the middle of your code for the receiving page and you're defining and adding the event listener twice, you're also not use postMessage correctly. Instead of this:
childWin = postMessage('message', '*');
...it should be this:
childWin.postMessage('message', '*');
If you want to learn more about postMessage, read this.
The other issue is that the message won't be received by the newly-opened page unless the page is opened before the message is sent. You're trying to send the message immediately after opening the new page, and the message is reaching the new page before the event listener is added. You could get around this with a setTimeout, but if the new page takes longer to load then this might also be unreliable.
// This is what NOT to do:
setTimeout(function() {
childWin.postMessage('message', '*');
}, 1000);
Instead, the better way is for the child page to tell the parent page when it's loaded. Then the parent and child can communicate reliably.
Here is the full corrected code, sending page first:
<script>
var childWin;
window.addEventListener('message', messageListener, false);
function messageListener(event) {
if(event.data == 'ready') {
childWin.postMessage('hello second page', '*');
}
}
window.onload = function() {
childWin = window.open('http://my-main-site.com/indexjava2.htm', 'child');
};
</script>
And the receiving page:
<script>
window.addEventListener('message', messageListener, false);
function messageListener(event) {
console.log(event.data);
}
window.opener.postMessage('ready','*');
</script>
I have this code http://jsfiddle.net/xxL6e2fk/
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script type="text/javascript">
janela = window.open("https://www.sitepor500.com.br");
window.setTimeout(
function() {
alert($(janela.window.document).text());
alert($(janela.window.document).html());
},
5000
);
</script>
It just opens a window and tries to get the "text" and "html" of its content. The "text" is displaying the content correctly but the "html" is not. Anyone has any idea how to solve this problem?
there is no html on janela.window.document try using janela.window.document.documentElement instead or targeting the body tag within the new window.
$("body", janela.window.document.documentElement).html()
You can use something like this:
var janela = window.open('https://www.sitepor500.com.br');
janela.onload = function () {
setTimeout(function () {
console.log(janela.document.documentElement.outerHTML)
}, 2000);
}
But this can work only if you are asking it from the same domain (sitepor500.com.br)
I have two windows , the second is a popup , and I want to trigger an event from the parent (the first one where I have a link to this popup).
here's a javascript code for the trigger (in the parent window's javascript code):
winPop=window.open(opts.url,opts.nom,"width="+opts.width+",height="+opts.height+",top="+opts.top+",left="+opts.left);
winPop.onload=function(){
$(winPop.document).trigger('connected', {
jid: "jid",
password: '123'
});
}
This javascript code launchs the popup and tries to trigger an event bound in popup (ready) function:
$(document).ready(function () {
$(document).bind('connected', function () {
alert("Hello , I'm here");
});
The problem is that using the previous javascript code .. the bound event is not triggered as predicted.
Thanks in advance
I had done this earlier with something like this:
var realWindowOpen = window.open;
window.open = wrappedWindowOpen;
function wrappedWindowOpen(url, name, specs, replace) {
window.open = realWindowOpen;
var windowHandle = window.open(url, name, specs, replace);
if (windowHandle)
console.log("New Popup Window created: ", {name:name});
else
console.error("New Window Failed. " + {name:name});
if (popupFnCreationNotify) {
popupFnCreationNotify(windowHandle);
popupFnCreationNotify = null;
}
window.open = wrappedWindowOpen;
}
// Calling example
var popupFnCreationNotify = function() {
console.log("I got called back");
};
window.open("my url");
Please note:
realWindowOpen always points to window.open.
I wrap the actual window.open with wrappedWindowOpen as you can see in the code.
Before calling window.open, the caller sets the popupFnCreationNotify to any callback function they wish.
I opened a popup window by window.open in JavaScript, I want to refresh parent page when I close this popup window.(onclose event?) how can I do that?
window.open("foo.html","windowName", "width=200,height=200,scrollbars=no");
You can access parent window using 'window.opener', so, write something like the following in the child window:
<script>
window.onunload = refreshParent;
function refreshParent() {
window.opener.location.reload();
}
</script>
The pop-up window does not have any close event that you can listen to.
On the other hand, there is a closed property that is set to true when the window gets closed.
You can set a timer to check that closed property and do it like this:
var win = window.open('foo.html', 'windowName',"width=200,height=200,scrollbars=no");
var timer = setInterval(function() {
if(win.closed) {
clearInterval(timer);
alert('closed');
}
}, 1000);
See this working Fiddle example!
on your child page, put these:
<script type="text/javascript">
function refreshAndClose() {
window.opener.location.reload(true);
window.close();
}
</script>
and
<body onbeforeunload="refreshAndClose();">
but as a good UI design, you should use a Close button because it's more user friendly. see code below.
<script type="text/javascript">
$(document).ready(function () {
$('#btn').click(function () {
window.opener.location.reload(true);
window.close();
});
});
</script>
<input type='button' id='btn' value='Close' />
I use this:
<script language='javascript'>
var t;
function doLoad() {
t = setTimeout("window.close()",1000);
}
</script>
<script type="text/javascript">
function refreshAndClose() {
window.opener.location.reload(true);
window.close();
}
</script>
<body onbeforeunload="refreshAndClose();" onLoad='doLoad()''>
when the window closes it then refreshes the parent window.
window.open will return a reference to the newly created window, provided the URL opened complies with Same Origin Policy.
This should work:
function windowClose() {
window.location.reload();
}
var foo = window.open("foo.html","windowName", "width=200,height=200,scrollbars=no");
foo.onbeforeunload= windowClose;
In my case I opened a pop up window on click on linkbutton in parent page.
To refresh parent on closing child using
window.opener.location.reload();
in child window caused re open the child window (Might be because of View State I guess. Correct me If I m wrong).
So I decided not to reload page in parent and load the the page again assigning same url to it.
To avoid popup opening again after closing pop up window this might help,
window.onunload = function(){
window.opener.location = window.opener.location;};
If your app runs on an HTML5 enabled browser. You can use postMessage. The example given there is quite similar to yours.
Try this
self.opener.location.reload();
Open the parent of a current window and reload the location.
You can reach main page with parent command (parent is the window) after the step you can make everything...
function funcx() {
var result = confirm('bla bla bla.!');
if(result)
//parent.location.assign("http://localhost:58250/Ekocc/" + document.getElementById('hdnLink').value + "");
parent.location.assign("http://blabla.com/" + document.getElementById('hdnLink').value + "");
}
You can use the below code in the parent page.
<script>
window.onunload = refreshParent;
function refreshParent() {
window.opener.location.reload();
}
</script>
Following code will manage to refresh parent window post close :
function ManageQB_PopUp() {
$(document).ready(function () {
window.close();
});
window.onunload = function () {
var win = window.opener;
if (!win.closed) {
window.opener.location.reload();
}
};
}
