I am currently using the following JS code to trigger a file download without leaving the page I'm on:
var iframe = document.createElement('iframe');
iframe.style.display = 'none';
document.body.appendChild(iframe);
iframe.src = "/somefile.zip";
It works well pretty much everywhere I tested except on both the stock Android browser and Dolphin, where the download doesn't start at all. So far so good, after some research this hidden iframe trick happens to be known not to work on the Android browser.
But I tried several other methods to trigger the download on the Android browser, including window.open() (not reliable because popup blocking is enabled by default), or <a target="_blank"> with a simulated click() (which from a popup blocker perspective amounts to window.open() and gets blocked), or document.location = ... which downloads the file but breaks my app.
The problem with the latter document.location = ... is that this is a Comet application (server-push / long polling) so I really can't leave the page I'm currently on (and "leaving" includes changing document.location even for a file download, even if apparently the browser stays on the current page) otherwise the long polling connection is stopped and the updates stop, the app breaks. This obviously also applies when clicking normal links, either manually or simulated.
So in order not to break my app I really need to trigger a file download without leaving the page I'm on. Unfortunately I didn't find any viable solution that also works on the stock Android browser.
Any ideas?
Thanks for reading me.
Try using the anchor and simulated click without using a target=blank
I say this because I had a similar download consisting of an iframe and a simple link as fallback. The iframe worked on everything but the android, but the simple link would download successfully without leaving the page.

I have a site embedded in an iframe from where I want to launch a mobile app. The following is bound to an onClick action on my button, and works in both Chrome and Firefox on my Android:
window.location = "scheme://app.com/?action=xxxxx"
However, when trying on Safari on iOS, nothing happens at all when clicking the button. If i go to the site directly (instead of iframing it) it works perfectly.
The same thing happens if I use an anchor tag:
I tried to fix this by using window.top.location, but then I run into Same-origin policy issues. The site that is hosting the iframe is on a different domain which I can't control.
Is there a workaround for this?
Let’s say I have a webpage and it has a button with an HREF attribute. I want the HREF of that button to be opened on Safari browser if the button is being clicked from an iOS device, even if the user is accessing the page on Google Chrome.
As of now, I only need to handle this situation for Chrome and not any generic browser. The way I see it, there are two parts to the problem:
Identifying the OS of the Client Machine: This I might be able to do easily.
Opening the Popup on Safari from Chrome: This is the tricky part I am not sure if it is possible.
I am looking for possibilities of accomplishing the second part.
Short Answer: no.
Long Answer: Some iOS apps have defined URL schemes that can be used to access the app directly from the browser. For example, twitter://timeline. But Safari for iOS does not have one.
You can detect the OS the user is using and if it Chrome then suggest the user to open it in Safari and also provide the link where to download it from. Or you can also suggest the user to make safari their default browser. ( Also provide a link on how to do that to them).
The requirement is I get URL of excel file in webservice response. I want to open this URL in new tab/window using javascript.
window.open(url, '_blank');
doesn't work in mac safari.
I also tried creating <a> with target="_blank" and trigger click.But it didn't work with Mac safari.
Is there any way to achieve the requirement?
Open the excel file in some specific div will also serve if it is possible.
Thanks.
Do you have a popup blocker installed ? if yes then read this . Safari/Chrome have built-in pop-up blockers that stop this from working. The only javascript that is allowed to open a new window in Safari/Chrome is javascript directly attached to click handlers (and other direct user input handlers). In past versions people figured out some ways to cheat (like generating some other element -- a form or div -- and simulating user input with javascript), but newer versions are smarter about detecting this. I'd recommend re-configuring things so that you don't use a delayed pop-up -- that is the kind of thing that can generally be jarring to a user after all.
For a friend I'm creating a narrowcasting (well, not really, just to one screen) page which reads content from his webshop and shows a slideshow with highlighted items, together with his logo and the time.
To run this I'm using an Android 4.1 device with a screen, I've installed Chrome onto the device which works properly. Everything is going pretty good so far, there's just one thing that annoys me. As we speak I'm using the Fullscreen API to go fullscreen as soon as the user presses the enter key. But due to changing content I want to do a refresh once in a while to fetch new content.
Here's where the problem lies: once the page refreshes it leaves fullscreen mode. I have been looking for settings in Chrome Android to allow fullscreen mode without a mouseclick or keydown event but haven't succeeded so far. Is there any way I can get the result I want (going fullscreen without a click of keydown)?
The reason I'm using Chrome Android is because this browser gave the best HTML5 support (for future use) and the best resolution (1280x720). But it's lacking a fullscreen mode I can use from within the browser. I tried Firefox for Android with a fullscreen plugin, that worked perfectly (not leaving fullscreen when refreshing), but Firefox only gave me a 960x520 viewport which is pretty small.
There's just one thing that comes up in my mind for now, which is doing an AJAX request to fetch the new content and replace the pages HTML with the fetched HTML (or perhaps just the 'slides' container).
Thanks for thinking along!
This code will do the same thing as refreshing the page automatically. I'm not sure if it'll prevent you from exiting fullscreen because I don't have a working copy to mess around with.
$.ajax() //Get the current page
.done(function(msg) {
document.documentElement.innerHTML = msg;
});
I don't recommend doing somthing like this, however. Your best bet is to abstract the part of the page that needs to be updated to it's own page, ie:
$.ajax("http://example.com/get_next_element")
.done(function(msg) {
$("selector_for_fullscreen_element").html(msg);
});
I made a small webpage for some of my friends, and one of them is having an issue.
I'm using javascript to reload an iframe like so:
↺ Repair
Using jQuery, but for one of my friends using Firefox 21.0 on Windows 7, this causes the page to instead entirely change to the iframe itself; specifically, the livestream widget.
Livestream tends to bork fairly frequently, so the repair button is fairly important to the watching experience. Is there a way I could implement this differently so this doesn't happen to him?
Try binding to the click event instead:
HTML
↺ Repair
Javascript
$('#repair').click(function(e){
var pl=$('#player iframe')[0];pl.src=pl.src;
return false;
});
