问题 My main goal is: Going to my application, open a link there in a new tab, make something in the new tab and send an event to the parent-main tab to refresh.

问题 I have the following script that works well in Firefox and Chrome (not sure about other browsers), but it doesn't work at all in IE. It basically opens a popup which appends a div to highlight an item in the window opener. I want it to work across multiple pages on the same site, so I didn't want to add a function to create the div in the main window (window.opener). Sorry I couldn't post a working demo - window.opener doesn't work in a bin. <button>Open popup</button> <script type="text

问题 My application runs in Local Intranet zone which launches a popup. This popup opens another page in my application (Local Intranet zone) which redirects to an authentication page (Internet zone) which after successful authentication sends back to my application page ( Local Intranet zone).

问题 In the first page I have window.tmpstr = 'aaaaaa'; window.open ('second.php','_self',false); in second.php alert(window.opener.tmpstr) This alerts 'undefined'. when I change '_self' to '_blank' it works. How can I pass the variable when I want the new window to open in the same window. 回答1: You can't, not like that. By calling window.open using _self , you simply redirect the page to the second.php url. Options you can use are : Adding it as a parameter using the hash tag (second.php#tmpstr

问题 I have built an Excel add-in, it opens a popup by window.open , then the add-in communicates with the popup site. I just realised that it does NOT work in Excel for Windows, the reason is that the popup can NOT get the host by $window.opener . To illustrate this and avoid cross-domain, I have made a xml, which refers to the add-in and the test page. It works well in Excel Online in Chrome and in IE. However, while running it in Excel for Windows, $window.opener returns undefined . Could

Inside this pop up i have a link that clos my pop up and redirect the url of the parent, like this : window.parent.opener.location = "http://google.fr"; or window.opener.location = "http://google.fr"; Both are working but in some versions of IE, they don't. My parent page isn't on the same domain of my children page, but even when it is the case, it still doesn't work. IE puts a message at the bottom asking if I want to let the website do this. I'd
