问题 How detect "refresh" event with prototype? A Cross-browser solution? Thanks, Celso 回答1: There's no way to detect refreshes in particular, but you can catch the browser before the page gets unloaded (which happens when the user refreshes the page - as well as when they 'move' to another page) In prototype this would look something like this: Event.observe(window, 'beforeunload', yourFunction); If you need to tell the difference, you could always bind some code to the links on your page that

问题 I'm trying make a firefox add-on, which reloads a page automatically under some conditions. First I add a contentScript to a tab to get some information on the page in my addon tab.attach({ contentScript:self.port.emit... I have it working to the point of the refresh with tab.reload(); but then an alert pops up every time "if it should resend data". I want to resend the data automatically. How and where do I do it? In the add-on or in the contentScript? Has it to do with the Load Flags

问题 Situation: url: http://mydomain.com/test.html#somehash test script: $(document).ready(function () { console.log("page initiated"); if (window.location.hash) { console.log("hash changed (if-statement)"); } $(window).on("hashchange", function () { console.log("hash changed (on statement)"); }); }); The script can also be found on fiddle, but the environment is not suitable to display the behavior. The problem I get is when I click on the browser addressbar and hit enter without any changes.

问题 I am building a single page javascript app and when the application starts I use a single javascript file to load every other file I need on the fly. When I hit refresh, according to firebug, my HTML page as well as javascript pages will load with a 304 Not Modified Error and my javascript stops working. I understand this is due to browser caching, but how can I avoid this? I load the initial HTML page with a single script call <script src="js/config.js" type="text/javascript"></script> and

问题 I have found this on all browsers tested - IE, Firefox, Chrome and Safari on Window sand Safari on Apple. Allegedly, a browser refresh, back button or forward link should dump the browser nodes and javascript variables and objects, etc. This appears to not be the case for WebGL. I first noticed it when developing a complex WebGL application that requires about 100MB to 200MB of memory. While developing, I have to do a lot of refreshes and my computer would start to slow down and freeze after

问题 I use the template data context inside a template's created function. Template.temp.created = function() { console.log('this.data'); }; When I go to the page normally--i.e. click the link to the page--I see the console log the correct data object. When I hit the refresh button on the page, this.data is null . Why? Also, I am using iron-router to set the data context: ... this.route('temp', { ... data: function() { return MyCollection.findOne(someId); }, ... } ... 回答1: If you want to wait

问题 Form get's resent on refresh, I had read about header("Location:my_page.php") unset($_POST) , but I'm not sure where to place it.

问题 Let's say that someone decides to press F5 or the browser's reload button. Is that possible to open a specific url in the same tab? 回答1: Like posted in comment, if you display prompt, this is possible using following ugly hack: var a,b; window.onbeforeunload = function (e) { if (b) return; a = setTimeout(function () { b = true; window.location.href = "//test.com"; }, 500); return "Now you will be redirected to new page if choosing to stay there..."; } window.onunload = function () {

问题 How can I redirect to a controller action when the browser's back button is clicked.

I have a controller called "Notifications" An action in the contoller called "Unlock" whick takes "id" as an argument.

问题 I have a button that has click event in my C#. This works great. However afetr pressing F5 to refresh the page I noticed the button event is fired. This occurs every time I click F5. I've added if(page.IsPostBack) and the method still runs. Is there any way to stop this method from firing when the F5 Refresh button is clicked?
