I am opening one Popup window on Button Click in main window, it is for Image Uploading.
when I am uploading Image , i.e. on Upload button click I am closing this Popup window and opening new Popup window.
And Now I want to display the Popup data to Parent window without refreshing, But I am not getting Parent window object.
i.e. window.opener or window.parent. Please give me help. How I will get Parent window object?
you can try this,
When first popup window is opened(uploading image window) get parent window object for this popup and store in some variable(java script variable ) like this
var parentWindowObject=window.opener;
Try passing this object variable to the second pop up window( on upload click) and in this page you will get it main page window reference (parentWindowObject) and using this you can fire new request to main page to post your required data as follows
parentWindowObject.location="your request";
Reason for not using window.opener in second popup
As you are opening a new popup from the present popup. The parent for the newpopup will be the popup which you are opening from here is your upload popup and you are closing the upload popup once you click on upload so for the new popup the value for window.opener(a reference for the parent window) will be null.
You can access the parent window by using window.opener
See window.opener
which returns a reference to the window that opened this current window. When a window is opened from another window, it maintains a reference to that first window as window.opener. If the current window has no opener, this method returns NULL.

Is it possible to check if a window was opened from a window.open() with the new opened window itself. I only want the website I am opening to be display a specific context when opened from a window.open(). It is cross-origin. For example: if the URL is accessed and not opened from a window.open(), I want it to redirect elsewhere. I know this is possible from the parent window, but not sure if it can be done from the child window
Thanks!
You can use window.opener. This will return a reference to the window that opened the current window or null if it is not opened by open().
if (window.opener) {
// Opened from another window
} else {
// Not opened from another window
}
Here's what I intended:
1. The user clicks an URL on a window and it opens in a new tab (the newly opened tab has the same domain as the original window).
2. The opened tab sends a message (using postMessage) to the original window where the user clicked the URL.
Unfortunately, the opened tab can't get a reference to the original window. I've tried window.opener and it did not work. It seems that most methods would only work if the tab is opened using window.open.
I've considered making the original window sends a message to the opened tab. That way the new tab could get a reference to the original window using event.source. So far I can make the original window detect when the user clicks the URL by adding onclick to the URL, but it doesn't fire if the user opens the URL by pressing the scroll wheel, and I also can't figure out a way to make the original window get a reference to the opened tab.
When a user clicks on a link with the rel attribute set to opener, the window.opener property is set on the new tab or window. From there you can call a function that is defined on that window.
// first tab:
window.sendMessage = function (data) {
// handle message
}
// new tab
window.opener.sendMessage(data)
IS there a way in Javascript to control the status of an open pop-up window?
I open the pop-up window with javascript and I need to close it at a certain point, specifically when the URL of that pop-up window contains these parameters:
oauth_token
and
oauth_verifier
ie: http://mysite.com.com/dev/uspolitics_pulse/functions.php?oauth_token=XX184mmCiV1Vp5EXNAdswiwrOUrZBkGx7bAdE0UwCTU&oauth_verifier=rIJJPdAPFzXQFsNvZufdSKTZdImGxSgyN7xKgNZz644
The function open returns the window object of the pop-up window.
That object has a method called close that can be used to close the pop-up window. It has the same properties as the global window object like location that can be used to get the URL.
Anyone knows the difference?
The problem I met is that the page stops working correctly when opened by window.showModalDialog
window.showModalDialog vs window.open
Window.open will open up a new window through Javascript, with the URL and other features of the window that u pass as parameters. Here the parent window which opens the new window and the child window are independent windows.
Eg. Below
`window.open('winOpen.htm','name','height=255,width=250,toolbar=no,directories=no,status=no,
linemenubar=no,scrollbars=no,resizable=no');`
Window.showModalDialogue again works smilar to a window.open only diffrence being its a Modal window, It opens up as a new window but doesnt allow the user to access the parent window, unless you explicitly close it.
Here the child window is dependent on the parent window. If you close the parent window the child would also get closed.
window.showModalDialog("xpopupex.htm","name","dialogWidth:255px;dialogHeight:250px");
ShowModalDialogue windows can be used when u want the user to perform a particular action in the new window before he access the parent window again. like login before he can access the parent page..
tryed to make it as simple as possible...hope this help.. ;)
Using JavaScript I open the pop window and parent window is inactive at this time,
I wanted to active parentwindow through popwindow. (this is a web project on Java)
You can usually window.opener in JavaScript to get at the window that opened at popup.
