I have a script where it opens a window for online application after executing some other scripts.
window.open() is not called on any click. It is getting called in a script and browser prevents the new window from appearing.
How to overcome this?
Here is the code:
window.open('/search/applyonline?jobid=".$jobDetails->getIdjob()."',
'applyurljob',
'height=550,\
width=800,\
toolbar=no,\
directories=no,\
status=no,\
menubar=no,\
scrollbars=yes,\
resizable=yes,\
left=200,\
top=250')
Popup blockers will block windows from being opened that are not in response to a click event. Therefore you can:
Ask your users to turn off their popup blocker (not nice).
Change your scripts to work in response to a link or button click.
Use fake windows such as a jQuery UI dialog.

I have a Chrome extension that does word substitutions on pages. Currently I have a popup that opens when I click on a browser action which lets the user control whether or not to perform the substitutions. I also have a background script running that sends a message to content scripts when a page refresh happens using a chrome.tabs.onUpdated event handler.
My problem is that when I refresh the page no substitutions are made unless the popup is open (which is only possible when I have the inspect elements panel open on the popup, because otherwise the popup closes when I refresh).
Has anybody had experience with this behavior before? What additional instrumentation should I add to diagnose the problem? Is there a different extension architecture/code arrangement I should be using?
Thanks in advance!
If you use localStorage on a given page you can probably store whether or not to substitute words. I think refreshing a page is similar to opening a new tab, so your script gets reinjected/reloaded rather than staying open and receiving an onupdate message.
I want to create a "popup window" that get focus each time the button is clicked. The function below executes fine from an onclick event but does not execute as expected when the parent page is refreshed and executed from an onload event.
here is my function:
function PopupDelete(delete_images)
{
var win = window.open('URL','PopupDelete','width=500,height=400,scrollbars=yes');
win.focus();
}
So if I use this from the button below it works as expected.
<input type="button" name="delete" value="Images" class="smallbutton" onclick="PopupDelete(delete_images);">
Now the problem I am having is we are using another method called set_mode on the button instead of directly calling the PopupDelete function.
function set_mode(mode)
{
document.MASTER.mode.value = mode;
document.MASTER.submit();
}
<input type="button" name="delete" value="Images" class="smallbutton" onclick="set_mode('delete');">
It sets the mode in the master form as Delete and submits the form. The landing page is the same page where the form is. So it does some php validation and executes the PopupDelete function with onload method within the body tag.
<body onload='PopupDelete(delete_images)'>
If there was no pop up window open it works fine but if the pop up window was already open and minimized, then the pop up window does not get the focus. The funny thing is it does recognized and updates the contents rendered on the pop up window but does not recognize the .focus().
Any suggestions will be widely appreciated.
Both opening a popup window without user interaction and focusing a popup window without user interaction is a problem is due to browser security. Also because security is maintained independently, this is browser specific.
It appears that you can open a popup window without user interaction if the user has already have accepted to show blocked popups. But allowing popups does not allow for calling the focus method on any popup window object. This other SO answer touches on this if you would like more information.
You can demo this problem with the following code. Loading the page does not allow for the popup to open in neither Safari, Chrome, or Firefox (keep in mind I'm on a mac so the browser results may be different for windows). If you allow the blocked popup, or already have the popup window open from previously visiting the site, then the window will be reloaded with the url in all 3 browsers. Only Safari allows calling the focus on this already popped up window without user interaction (onload), Chrome and Firefox do not. But as you can see clicking the focus button does still focus the popup window on all 3 browsers, showing that it is possible, but the browser is just blocking it. So from what I can tell this is only possible in Safari (once again keep in mind I have not tried IE). But either way I don't believe it would be good to force your users to use a specific browser to view your site correctly.
var w;
function PopupDelete(delete_images) {
w = window.open('/testing/t/', 'PopupDelete', 'width=500,height=400,scrollbars=yes');
console.log(w);
w.focus();
}
$(function () {
PopupDelete();
$('#open').click(PopupDelete);
$('#focus').click(function () {
console.log('f', w);
w.focus();
});
});
DEMO
Also keep in mind, even if you could do this, when you reloaded the parent it's reopening the popup window and replacing the previous one (and this has to be done because to my knowledge you can't get a window object of a previously opened window, there is no way to maintain that variable to focus it without reopening it first). So this popup window wouldn't keep it's integrity anyway. I believe there must be a better way to completing this task.
On the page load you can show this popup
$(document).ready(function () {
window.open("URL","Hello","width=500,height=500,scrollbars=yes")
});
I am opening a popup after main window load.
Problem:
When user actually click on link the popup opens without complaining anything.
But when I am using Javascript call to click on href, I am getting popup blocker.
I am suspecting that, browser identifies that, popup is opening without any actual operation by user and that's why it is blocking popup.
In herf, I am calling a javascript method to open the popup.
I searched all the questions regarding opening popup and simulating the click like this, these works fine to simulate the click but still getting popup blocker.
Is there any workaround to fool browser?
You can't fool the browser per-se in this scenario. You could however, launch a div as an overlay on the main window if that's an option.
There is an iframe on my site which is hosted on another domain. It can communicate to the main site via window.postMessage. I do have a button on that iframe which calls a JS method on the main domain, which then triggers a new window.
It all seems good but since the user click event is generated on the iframe domain and window is created on the main domain, browser thinks that this is an automated popup, and blocks.
Is there anything I can do to prevent browser from blocking the window?
since that is browser based you cannot overwrite browser settings. But you can use javascript "modals" which are very useful since they are not pop-ups but they don't have the functionality of an pop-up
I want to open a new window in button click.I have used a code.
Response.Write("<script type='text/javascript'>detailedresults=window.open('YOURPAGE.aspx','_blank');</script>")
It is behaving like a pop up window,but it is not working in IE 7.0 & Chrome.Please help me to solve that issue.Thanks in advance.
In most modern browsers, the browser will prevent the pop-up if the javascript wasn't run as the result of a user action. Actions like onClick are ok, but script that executes as soon as the page loads will usually be blocked.
HTH,

Why not set the target to _blank on an anchor tag instead of a button? e.g.
<a href="yourpage.aspx" target="_blank" />
Does that work for you?
Due to the prevalence of very irritating adverts and attacks based around opening a popup window as soon as a page loads, most modern browsers will block them.
You can only have a popup if it is direct response to a user event (e.g. in an onclick handler).
You cannot trigger on at page load time.
