I am using jquery onbeforeunload event in asp.net application.
If i write event as given below then its working fine and display confirm dialog box.
var vGlobal = true;
var sMessage = "Leaving the page will lost in unsaved data!";
[ Working ]
> window.onbeforeunload = function() {
> if (vGlobal == false) return
> sMessage; }
but its not working if i use bind method like as given below
[ Not working ]
$(window).bind("beforeunload", function(e) {
if (vGlobal == false)
return sMessage;
});
Is there any difference between these two methods.
Code on aspx:
<asp:TextBox ID="txtName" runat="server"></asp:TextBox>

i am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).
var onBeforeUnloadFired = false; window.onbeforeunload = function (sender, args) { if(window.event){ if(!onBeforeUnloadFired) { onBeforeUnloadFired = true; window.event.returnValue = 'You will lose any unsaved changes!'; //IE } } else { return 'You will lose any unsaved changes!'; //FX } windows.setTimeout("ResetOnBeforeUnloadFired()", 1000); } function ResetOnBeforeUnloadFired() { //Need this variable to prevent IE firing twice. onBeforeUnloadFired = false; }
I'm trying to achieve an edit screen where the user is warned before navigating away. It works fine except I get the pop up for normal post backs of button clicks. I'm hoping to avoid this so I'm figuring if I could determine which button was pressed it would work. Does anybody know how to determine which button was pressed in the indows.onbeforeunload? Alternatively anyone know a better approach to what I'm trying to achieve?
I have the following Jquery function to notify the user with a prompt when they have unsaved changes (similar to how SO does it) and are trying to leave the current screen.
<!-- in my aspx page --> <script type="text/javascript" language="javascript"> window.onbeforeunload = function() { if (HasPendingUpdates()) { return "Changes you have made will not be saved."; } } </script>
This works as expected and shows the message box when the user tries to click a href to browse away or use the back button etc. The problem I am having is that one of my links is a asp:LinkButton because it needs to fire off some server side code before leaving the page. When the user clicks this LinkButton they get the prompt twice.
Scenarios:
User clicks the LinkButton Prompt appears and user clicks the cancel button. Prompt disappears and user is still on screen. GOOD. User clicks the LinkButton Prompt appears and clicks the OK button. Prompt disappears and the same prompt shows again. User clicks OK again. Prompt disappears and user moves to the next screen and all is good.
So why am I getting the second prompt??? How is the OnBeforeUnload firing twice?
In one of my applications, i created the left navigation menu using treeviewcontrol. Each and every node in the treeview is calling a URL in the application.Content pages are dynamically created ASP.NET controls.There is no submit or save buttons in these pages. When the user finished entering the data and go to another link in the tree structure, the data need to be saved in the database and go to the next link.I tried this using OnBeforeUnload and Document.form1.submit, the aspnet form is not submitting, so there is no postback. I also tried __dopostback method call from the javascript. Still not able to get it working.
On my parent page I added a script which ask confirmation befor page unload (On every button press) using window.onbeforeunload, The problem i use to open a subPage on this parent page, and on closing of the subpage i use to reload the parent page, but it ask confirmation and I dnt want that....
What I want to do: dispose of a session upon detecting an "OnBeforeUnload" event in the client. I know it doesn't fire 100% of times (90% accuracy works fine for me)
Here I saw how to do it with ajax, this system, however, breaks down with ajax: I can't use it at all.
I am using fullCalendar and I'm able to populate the calendar with events very easily. And I undertsand the best way to add events to the calendar is through the database. What I need now is to catch and populate an edit event form after the user clicks an event.
There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8.Here is the test code:
This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem.
I have a link button in a repeater control. the li element is drag and droppable using jquery. when the page loads the the link button works perfectly, the jquery that is attached and the server side code both execute. when I perform a drag and drop then click on the link button it doesnt not fire. when i click it a second time it does fire. If i perform 2 or drag and drops in a row the link button doesnt fire a as many drag adn drops as i before it will fire. for example if if perform 3 drag and drops then it will take about 3 click before the events are fired.
I try to unbind an event and then rebind a new event to an input element of type text. I think the unbind works, as teh default behavior is disabled, but the rebind not.

I have a Silverlight application hosted inside an asp.net website. In my silverlight applicaiton, if I select a theme. Then, theme changes will gets fired. I want to get notified in asp.net web page, when the theme changed event is fired inside the silverlight application. Note: Also, I don't want to use a data base to maintain the state of the application.
I'm having trouble managing how to call upon databind from clicking on a row over an already populated repeater that will populate data regarding the row clicked TO another repeater on the same page.
I've succeeded doing that with postback, calling a jquery click event of that row, taking the data of the specific row and passing it onto a "Querystring" and after postpack, it will be pushed into a Session which the ObjectDataSource of the secondary repeater will recognize and populate the data tables accordingly.
The problem is, I must do it without a postback or in other words purely on client side.
I've found posts about making a click event with jQuery for a button, however I need a little more then that. When any postback occurs on a page, I need to fire off a jQuery click event. Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this.
my page are 1 checkbox and 1 hidden label and 1 hidden panel. With the help of forum member raghav_khunger I've managed to write the code which shows panel and label when checkBox is checked. I've also added the code which is checking on every page post back the status of checkbox and hide/show panel and label appropriately. This is working fine.However when I add jQuery Safari checkbox plugin [URL] problems appear.
Looks like the code which is handling click event is doing reverse thing: when panel and label should be hidden are shown. I can change this but then there would be problems because of the second part of the code which is checking checkbox on page load. So when I check the checkbox nothing happens. I must uncheck it and label and panel appears. But if panel is uncheck the label and panel would be hidden because on next page load (when user clicks button next).As I said before the same code is working fine and it's test in all browsers (IE,FF,O,S,C). Maybe there is problem with checkbox plugin since it's in beta version.
I need to use the jquery progress in my web application, basically when the user clicks the submit button, the screen must dim to grey (similar effect to lightbox) and then the progress bar must activate showing the user the progress. When the progress is fully complete, the application should return to its normal color and everything should function properly.I cannot find any examples
I have an image on my page than can be changed from a fileupload asp.net control on the page, i want to provide and alternative to clicking the button by allowing the user to click their image. i gave the fileupload a class 'jqueryPhotoUploadTrigger' and it renders like this:
$(document).ready(function() { $("#clickMyColl").click(function () { alert("image has been clicked"); $('.jqueryPhotoUploadTrigger').click(); }); });
the alert does show so i know the script is firing when i click the image. i was just hoping the .click would fire the event on the button but it didnt. can i do it this way or must i find an alternative?
I'm going nuts here.. This is what i like to do: When i click my serverbutton i want a fade message to show and then execute as usual all the servercode (db insert and more) i have in my button_click event in code behind. The fade effect works, but the servercode never executes. I don't know how many guides i have tried but it seems impossible to achieve this. I just want to fire the the code in my click_event. I really hope someone of you can point me in the right direction.
I had thought that returning false would keep my asp.net OnClick even from firing, but it still does. I've confirmed that it is getting to the return false section of code using alerts. Is there anything I can do to stop it from firing using jQuery/javascript?
The problem is that when the user clicks on the cell but not the actual content of the cell, the script doesn't trigger because it's not linked to the whole cell. So I'm writing a small script to extract the link and assign its value to a click event handler for each cell. This is what I have so far:
$('.MyLink').each(function () { var TheLink = $(this).attr('href'); var CellContent = $(this).html(); // alert(CellContent); var LinkExtract = TheLink.split(":"); //alert(LinkExtract[1]); var PagerCell = $(this).parent(); $(PagerCell).click(function () { LinkExtract[1]; }); //problem here $(PagerCell).html(''); $(PagerCell).html(CellContent); });
Both alerts return the expected content. However, the click event doesn't work.
