I am developing a SharePoint App that basically launches a form in a Windows 8 application once the action is clicked. This is working perfectly fine. However, once you select this action, you are redirected to a page that basically holds some parameters to launch the app. This page throws a window that asks the user if it's okay to launch the app:
How can I detect if this has been launched or not? Ultimately I'd like to detect if the user hits 'Allow' or 'Cancel' but either scenario will work. I am trying to redirect a user to the parent page once this window has launched (hopefully when the user clicks 'Allow'
Is this possible? I found a helpful thread here: http://support.smartbear.com/viewarticle/55730/
However, this thread is very useful but doesn't give me the answer I need. I've tried using jQuerys .blur and this works(ish). It isn't giving me a consistent response but looks like it's a step in the right direction (if I can't detect the window that launches). I've also tried the following code by using .hover but am receiving inconsistent results.
$(window).hover(function (event) {
if (event.fromElement) {
console.log("inactive");
window.location.href = "http://google.com";
}
else {
console.log("active");
}
});
At the highest level possible, I'm trying to redirect the user once the app is launched.
Thanks in advance for any helpful input.

I am presented with the following problem:
In my current web application with current browsers, the user can type in the navigation bar the name of a certain page: stackoverflow.com, when the user presses the enter button, before being redirected to the page in question, I need to update the status of a record in the database.
I have tried some events in the body but if the user does it this way it does not detect them.
I have also followed the following options without success.
How to detect if URL has changed after hash in JavaScript
Well I am not sure it will resolve your problem but you could probably send your database update request in the window.onbeforeunload event like this:
window.onbeforeunload = function () {
// do stuff
}
I'm facing a problem like this:
I've an HTML page , when I click a button it triggers a job on the backend server, the status on the page keeps getting refreshed and when it reaches a certain state a new window is opened through JS logic :
if (status) {
window.open(URL, "_blank");
}
Now, my problem is if this page is open on multiple browsers, or even multiple instances of same browser, the window.open() is triggered across all of them when the status is true.
Is there a way to make the window open only from the page or browser session from where the job was triggered? Please help.
I am developing a web application. And I wrote some JS script to be executed on document ready. But in chrome when we click on back button and go back to previous page it is executing all the js script again. But when I use same on firefox it do not execute the JS.
I have an accordion on a page and when user open any accordion and go on one of the link under the accordion and after that if again clicks the back button on the accordion page chrome is closing all the accordions as I have written the script to close all these on document ready. But firefox do not close.
Is there any way to fix this with javascript? So that I can put any condition like if(history.forward.length < 1){ do this....}
You can use the pageshow event to guarantee you always detect navigation to a particular page, regardless of whether the user presses the back/forward button or selects a link, and regardless of which browser is being used.
Then you can perform checks regarding the state of UI and perform logic as required (i.e. modify UI, prevent execution of additional JS).
window.addEventListener('pageshow', function(event) {
// check state of UI, etc.
});
The solution that came to my mind is using sessionStorage to know if it is a first time loading or not. Or even better, you can keep state of your accordions in session storage so it always be the way the user want.
In my case, the iframe was a hidden iframe (width and height zero).
This iframe is just an workaround from legacy system, developed 12 years ago. But still using nowadays on current application.
To solve it, i just redirected the page loaded into iframe to the blank page.
Example:
page_loaded_into_iframe.php
<?php
//do the php stuffs
?>
<script>
alert("hello world");
location.href = "about:blank"; // here, where the the magic happens!
</script>
Once pressed the "back button", the browser will reload a blank page.
Be aware that this might be not applicable if your case is not similar to mine.
In the Chrome Extension you can use the function:
chrome.webNavigation.onCommitted.addListener(function callback)
and in the callback function you may take a look to the arguments:
transitionType + transitionQualifiers
to look for:
"forward_back" The user used the Forward or Back button to initiate the navigation.
For deatils see chrome.webNavigation
Of course, this event can be communicated to the content script with the usual message model (refer to: Message Passing
I'm trying to reload my page every time the user puts my page in focus again or opens their browser. My code works, if the user is in the browser and changing pages, but it doesn't work if the user exit the browser (without actually shutting it completely down) and then opens the browser again, where my page would be the first site they see. I am testing this on chrome for android. Is there another event I need to listen for?
I am looking for a method to reload on all browsers as soon as the user enter my page, no matter what state it was in before - mobile browsers are especially important.
Code:
<script type="text/javascript">
onload = function () {
onfocus = function () {
onfocus = function () {}
location.reload (true)
}
}
</script>
This is a pretty crazy idea to reload the page all the time in full, your users will hate you. If you are going to do it, just do partial updates to the page.
Anyway, to answer the question, check the PageVisibility API(Chrome) or the specs. This event fires when the page is visible to the user either by bringing the app into focus or by changing tabs.
I have a simple logon page. When the user is validated, the window navigates to a new page. The javascript is window.open('http://www.google.com',"mytest",'toolbar=no'); My expectation is that when it navigates away from our logon page and opens the google site that the back button would be disabled. But it's not. Does anyone have any idea why?
It depends on your browser. Ultimately, all you can do with javascript's window.open() is tell the browser what you'd like it to do, but it's not obligated to do it. Browsers can and do ignore some directives based on user preferences.
I believe the option your looking for is 'location=no', as that hides the address bar and therefore the back button too. The toolbar is things like favorites/etc.
This is bad practice - what happens if the user has javascript disabled? If the browser prevents the js from removing the toolbar of the main window?
Instead, amend the logon page to detect whether the user is logged in before showing the login form. If logged in, show a message saying so instead of the form - that way, a user clicking back won't be a problem.
I find it very annoying when a website messes around with my browser window, and generally don't come back.
This is what worked for me. Instead of disabling the back key. I listen for on unload event. I then write the following in javascript:
window.onbeforeunload = function () { return "You should not press the back button while in this application. If you continue, your work will not be saved and you will need to log back in."}
Java Script pops a dialogue box with OK and Cancel options. If the user clicks cancel. The application stays right where they are. The script is embedded within the tags. For me this is the ideal solution. I found this at
