I'm trying to detect if the user is seeing a cached page or error page for lack of cached copy while offline I've tried using webview.getTitle() and webview.getUrl() but they give the title or url of the last page even in onPageFinished() I've also tried using javascript but it takes too long to return the title. javascript:Android.pageStatus(window.location.href)
Is there either a way to get the javascript to return a value faster or another way to get current page title.
The project in case the mistake is on my end

I am trying to make a navigation button that just sends me to the index page but shows a different text in the url.
so i found this line of code to help me do it.
window.history.pushState("index.php", "test", "Testie");
But the problem is when i run it in an onclick function it just takes the last value and puts it in the url bar.
That itself is not the problem its that i dont have a Testie.html/php file.
I want it to be send to index.php but make the appearance of Testie in the url.
How do i do it?
The purpose of history.pushState is to say:
Some other JavaScript has manipulated the page so what the user is seeing is the same as what they would see if they went to this URL.
It lets you get fast updates to the page and bookmarkable URLs with real content that is good for fast initial page loads and for search engines to index.
It doesn't send data to the server (you need to do that with other code).
It does mean that if the URL isn't actually handled by the server (as you say it is in your case) then the page will break if the user does bookmark the page (or refreshes it, or sends the link to someone, etc).
If you want to navigate to a URL with Testie in it, then the first thing to do is to make the server support it. Forget about JavaScript.
This might just be because I'm not entirely sure how to word it properly, but here's an overview of the problem.
I have a site where it pulls the main content using ajax, and by using pushState, I change the url. Say from "site.com/" to "site.com/area". But reloading this page (or entering it in the url) causes it to completely fail (because there's no such thing as site.com/area).
Is there a way to load the page from that link?
Note, that this isn't about the history / back and forward buttons. I simply want it to load a page from that kind of link.
The page must exist in one way or another. Depending on what server you're running it on you can redirect all requests to your first page if you want to solve it like that. Then you don't have to create a new page for all "routes", but can build it into your first page/application.
But the page must exist in one way or another.
Okay so there are solutions for this as in Modify the URL without reloading the page but I have one question regarding this.
So here is what I plan to do (let's assume my web address is example.com)
1. using pushState I plan to change the browser address to example.com/myprofile/myalbum. So to be clear, this new url may or may not exists but the browser address is changed regardless. In our case this url doesn't actually exist but we are using the address to mark a changed state of the webpage.
2. use ajax to load data regarding "myprofile > myalbum" to the same page.
But now here's the issue I have been thinking about. What if a user loads example.com/myprofile/myalbum directly on a, let's say, new tab. This page clearly throws a not found error because it doesn't exist.
So how do I load ajax corresponding to this fake url? For example http://www.usatoday.com/news/ seems to do this well (unless that's an iframe, which wouldn't be so nice).
You can add rewrite rules to your webserver, converting either specific URL's or some matching a pattern to something that your scripts can use to show the right page. You can have it rewrite the URL only internally, so the user still see the original URL in the browser. Such as:
RewriteRule /myprofile/(\w*) /index.php?path=/myprofile/$1
Different webservers will probably have different syntax, but they will be similar.
I have a jQuery plugin I use to dynamically create and render a form on a default.aspx asp.net page, then submit it. The page it gets submitted to is a pdf.aspx page. The page builds a PDF then uses Response.Write to write the file (application/pdf) to the browser. I use the same method to render XLSX files to the browser as well. It works really great, but I need a callback or some event to tell the button when to stop spinning. This prevents the user from continuously clicking the Excel or PDF buttons. Does anyone know a way to detect the file dialog window when it was not created using JavaScript? I am also open to other methods of callback from the server side as well.
The way I do that was suggested in response to a question I asked here a while ago by T.J. Crowder. I can't find the response from the last time I wrote this up because the Stackoverflow "search" facility is so incredibly lame, so I'll probably type in a blog post. The basic idea is that your client code (Javascript) should append an extra parameter when it submits the request for the download. The parameter should contain some generated random string (probably just the current timestamp is good enough). The server then looks for that parameter, and when it's preparing the response with the download file it also sets a cookie and gives it that random value.
Right after the submit (or right before; it doesn't really matter), the Javascript code should start an interval timer with a routine to look at the value of document.cookie and see if it contains that random string. As soon as the cookie does contain that string, then you know that the server has sent back its response and that the file download dialog has been presented.
I'm making Firefox extension and I have a problem with
variables. Extension works with file (chrome://myextension/content/document.html) opened in few tabs.
I want it to store a value in each tab, so I decided to store it in
one of the html objects, that have got "Object" id:
data="foobar"
node=gBrowser.contentDocument.getElementById("ObjectId");
node.setUserData('data', data, {handle:function () {}});
For some reason, this doesn't work, when I want to get this variable
in this way:
data=node.getUserData("data");
Can you spot an error in my code?
PS. This two pieces of code are separated methods. The html file is on
a hard disk
Do you set it and get it in the same document (tab) without reloading in between? That works for me.
If you're trying to persist the stored value across the reloads or share a value between all tabs that have the same document loaded, you've picked the wrong API as far as I can tell (the spec is rather long and I didn't bother to confirm that).
What are you actually trying to do?
