Opera 3 and Hotjava 3 give ' blank' as the URL of the popup,while Opera 5 on Mac thinks it is i. Opera 5.11- on Windows and Linux crash on the View Location link. There's one catch however: what exactly is the URL of the page in the popup?
As you might have expected, differentbrowsers have different opinions. I put a link 'View location' in the popup that displays the location.hrefof the page. Usually the location is this page, popup.html, that's because the browser sees the popup asa kind of extended part of this page. I noticed this problem because a colleague of mine wanted to use this sort of script for making a printerfriendly version of a page. Write the content into a popup, with minimal markup, and then let the userpress 'Print'. Unfortunately most browsers printed out the main page because they executed the print commandfor the location.href (the main page), which was not at all what he had in mind.
Interestingly, the self.close command always correctly closes the popup, not the main page.
In a specific page a user will press a button but on button press before the actual processing, I need occasionally to present to the user a list of options to select the appropriate one and use that selection in order to be able to proceed the processing. So essentially I need to display a pop-up window that shows a select box with available options and get the user's selection and then continue processing. So to do this I found that I need a combination of window-open/prompt/showModalDialog I found a way to present a pop-up window to the user with the options via var newWindow = window.open(', null, 'height=200,width=400,status=yes,toolbar=no,menubar=no,location=no'); newWindow.document.write('); newWindow.document.write('); newWindow.document.write(obj); newWindow.document.write('); newWindow.document.write('); Example for passing just one option. But I can not seem to find how to get back the selection.
The prompt on the other hand returns the selection, but I don't think I can make it display my select. The showModalDialog returns the selection, but seems to expect another web page as a parameter. So it is not suitable for me. How can I create my pop-up using plain javascript?

Window.open(' And it will open a new window with given URL. Most modern browsers are configured to open new tabs instead of separate windows. Popups exist from really ancient times.
The initial idea was to show another content without closing the main window. As of now, there are other ways to do that: JavaScript is able to send requests for server, so popups are rarely used. But sometimes they are still handy. In the past evil sites abused popups a lot. A bad page could open tons of popup windows with ads.
So now most browsers try to block popups and protect the user. Most browsers block popups if they are called outside of user-triggered event handlers like onclick. If you think about it, that’s a bit tricky.
If the code is directly in an onclick handler, then that’s easy. But what is the popup opens in setTimeout? Try this code. // open after 1 seconds setTimeout( = window.open('1000); The difference is that Firefox treats a timeout of 2000ms or less are acceptable, but after it – removes the “trust”, assuming that now it’s “outside of the user action”. So the first one is blocked, and the second one is not. As of now, we have many methods to load and show data on-page with JavaScript. But there are still situations when a popup works best.
Close Popup Window Javascript
For instance, many shops use online chats for consulting people. A visitor clicks on the button, it runs window.open and opens the popup with the chat. Why a popup is good here, why not in-page?. A popup is a separate window with its own independent JavaScript environment.
So a chat service doesn’t need to integrate with scripts of the main shop site. A popup is very simple to attach to a site, little to no overhead. It’s only a small button, without additional scripts. A popup may persist even if the user left the page.
For example, a consult advices the user to visit the page of a new “Super-Cooler” goodie. The user goes there in the main window without leaving the chat. The syntax to open a popup is: window.open(url, name, params): url An URL to load into the new window.
Name A name of the new window. Each window has a window.name, and here we can specify which window to use for the popup.
If there’s already a window with such name – the given URL opens in it, otherwise a new window is opened. Params The configuration string for the new window.
It contains settings, delimited by a comma. There must be no spaces in params, for instance: width:200,height=100. Settings for params:. Position:.
left/top (numeric) – coordinates of the window top-left corner on the screen. There is a limitation: a new window cannot be positioned offscreen.
width/height (numeric) – width and height of a new window. There is a limit on minimal width/height, so it’s impossible to create an invisible window. Window features:.
menubar (yes/no) – shows or hides the browser menu on the new window. toolbar (yes/no) – shows or hides the browser navigation bar (back, forward, reload etc) on the new window. location (yes/no) – shows or hides the URL field in the new window.
FF and IE don’t allow to hide it by default. status (yes/no) – shows or hides the status bar. Again, most browsers force it to show. resizable (yes/no) – allows to disable the resize for the new window. Not recommended. scrollbars (yes/no) – allows to disable the scrollbars for the new window. Not recommended.
There is also a number of less supported browser-specific features, which are usually not used. Check for examples. Let’s open a window with minimal set of features just to see which of them browser allows to disable. Let params = `scrollbars=no,resizable=no,status=no,location=no,toolbar=no,menubar=no, width=0,height=0,left=-1000,top=-1000`; open('/', 'test', params); Here most “window features” are disabled and window is positioned offscreen. Run it and see what really happens. Most browsers “fix” odd things like zero width/height and offscreen left/top. For instance, Chrome open such a window with full width/height, so that it occupies the full screen.
Let’s add normal positioning options and reasonable width, height, left, top coordinates. Let params = `scrollbars=no,resizable=no,status=no,location=no,toolbar=no,menubar=no, width=600,height=300,left=100,top=100`; open('/', 'test', params); Most browsers show the example above as required. Rules for omitted settings:. If there is no 3rd argument in the open call, or it is empty, then the default window parameters are used. If there is a string of params, but some yes/no features are omitted, then the omitted features are disabled, if the browser allows that. So if you specify params, make sure you explicitly set all required features to yes.
If there is no left/top in params, then the browser tries to open a new window near the last opened window. If there is no width/height, then the new window will be the same size as the last opened. The open call returns a reference to the new window. It can be used to manipulate it’s properties, change location and even more. In the example below, the contents of the new window is modified after loading.
Window.onblur = = window.focus; When a user attempts to switch out of the window ( blur), it brings it back to focus. The intention is to “lock” the user within the window. So, there are limitations that forbid the code like that.
There are many limitations to protect the user from ads and evils pages. They depend on the browser. For instance, a mobile browser usually ignores that call completely. Also focusing doesn’t work when a popup opens in a separate tab rather than a new window.
Popup Window Javascript Example
Still, there are some things that can be done. For instance:. When we open a popup, it’s might be a good idea to run a newWindow.focus on it. Just in case, for some OS/browser combinations it ensures that the user is in the new window now. If we want to track when a visitor actually uses our web-app, we can track window.onfocus/onblur. That allows us to suspend/resume in-page activities, animations etc. But please note that the blur event means that the visitor switched out from the window, but he still may observe it.
The window is in the background, but still may be visible. A popup can be opened by the open(url, name, params) call. It returns the reference to the newly opened window. By default, browsers block open calls from the code outside of user actions.
Usually a notification appears, so that a user may allow them. The popup may access the opener window using the window.opener property, so the two are connected. If the main window and the popup come from the same origin, they can freely read and modify each other. Otherwise, they can change location of each other and communicate using messages (to be covered). To close the popup: use close call. Also the user may close them (just like any other windows).
The window.closed is true after that. Methods focus and blur allow to focus/unfocus a window. Events focus and blur allow to track switching in and out of the window. But please note that a window may still be visible even in the background state, after blur. Also if we open a popup, a good practice is to notify the user about it. An icon with the opening window can help the visitor to survive the focus shift and keep both windows in mind.
. Introduction Nowadays, JavaScript Modal Popup window has become an intrinsic part of Web based application. Lately, I had a requirement where I needed to use Modal Popup Window. I Goggled for it and found many JQuery based Modal Popup Windows, but none of the code was fitting my needs. So I decided to create my own Modal Popup window without using JQuery which should be easy to use and is flexible. Using the Code First, you need include ModalPopupWindow.js file in your web page as given below: Once you have included the JS file, you need to create an instance of ModalPopUpWindow. Member 12597621 22-Jun-16 1:08 22-Jun-16 1:08 Hi, I actually need to display a warning message (say for example when a user is using an older version of broswer)on popup box.
Create Popup Window Javascript
That means i have write one script to detect the version of browser. Now what i iwant is to display a modal popup when user is using an older version of browser. ALso in you article you have written to include ModalPopupWindow.js file in my script, but i am unable to find that script on internet. Could you please provide me the location for that script. Member 12397728 20-Mar-16 18:07 20-Mar-16 18:07 This modal feature is what I have been looking for. Question is there a way to click on a navbar li to launch the modal window?
I understand the method in the parent code ( I think) but am have a problem trying to implement the modal feature from a navbar link. My main approach it to launch a window to control loading a file to a location. I think I can do this if each form page has its own instance of a control button. Any help would be greatly appreciated. Jennie Lay 25-Sep-15 2:03 25-Sep-15 2:03 Thank you so much for creating this great article.
You really save my day. I was looking for Modal Popup everywhere since I cannot use AJAX due to css limitations on my existing project. Jquery was also not an option since 'dialog' was not available in jquery 1.3.2(which is the current version we are using). And finally, I found your code and it works well for me, especially 'ShowURL' function. I changed a little bit in 'InitModalPopUp' function to show the dialog in center as much as possible. So, for var left & top, I divided with '4' instead of '2'.
It works really really great. Member 11021189 9-Feb-15 0:26 9-Feb-15 0:26 Good Evening Sir, as my Project lead requirement, i want modal popup window in the below scenario. For say, My projects involves roles, so according to specific role, they can not see the page, i want a modal popup that shows ACCESS DENIED message window on the parent page i needed, that means where i was, when i clicked on that page, if that user is having permission to access that (new page), he can enter otherwise i need a modal popup on the current parent page itself. Thanks in advance for ur reply.
Member 11369438 14-Jan-15 2:20 14-Jan-15 2:20 Thanks for sharing this code, I love what you have done. I added this to our ERP application (modified it a little bit). I was using jquery dialog boxes and decided to move on to something else. The ERP vendor started using jquery libraries, and they used old versions of the library. This caused me grey hairs.
I think the only thing I need to do is put in an overlay. That will prevent the users from bypassing the popup window.
Unfortunately we use IE 8 as our browser standard. The shadow box doesn't work in IE 8. I guess it's not available until IE 9 or 10.
