In my project there is a button search which seems to be the default button to trigger when enter key has been pressed. How can i detect a keydown event with jquery for a login button? Its an asp.net project.
View 1 RepliesI am using a Silverlight usercontrol in my ASP.NET web app.
The user control has several autocomplete boxes and it seems that the enter key never fires the keydown event in any of them while it fires for other keys.
I'm assuming that autocomplete boxes must handle the enter key in a different way, perhaps for chosing an item from the list. - Thus it works with simple text boxes.
I was thinking about overriding the eventhandler in a new deriving control...
I have a textbox on my page and the second a user puts something in the Textbox i need to make a save button visible.
I thought I would do that with a keyup or keydown even. However, all I can find in my Text box is OnTextChanged. This only fires when enter is pressed. This is not want I want.
Is there anyway to fire a Keyup or keydown event when the user types something into the textbox?
In case of C#, when we code a keydown event which usually works in server side, what happend? Can PHP do that? or should work only in javascript which is client side?

View 6 RepliesMy LogIn action originally looked like this:
return new RedirectResult(nameValueCollection["ReturnUrl"]);
But, I would like to know whether the client has JavaScript enabled before the home page loads, so I changed it to this:
return View(new LogInViewModel { ReturnUrl = nameValueCollection["ReturnUrl"] });
And send the following view instead of the instant-redirect:
@model Obr.Web.Models.LogInViewModel
@{
Layout = null;
string noJSReturnUrl = Model.ReturnUrl + (Model.ReturnUrl.Contains("?") ? "&" : "?") + "noJS=true";
}
<!doctype html>
<html>
<head>
<title>Loggin in...</title>
<meta http-equiv="REFRESH" content="1;url=@noJSReturnUrl">
<script type="text/javascript">
window.location = "@Model.ReturnUrl";
</script>
</head>
<body>
<noscript>
Loggin in...<br />
<a href="@noJSReturnUrl">Click here if you are not redirected promptly.</a>
</noscript>
</body>
</html>
The idea is that if the user does not have JavaScript enabled, they see a brief loading message, and the home page loads after a second. If JavaScript is enabled, the page reloads instantly. In the future I could even post to the server the dimensions of the viewport and such. Does this look like it would work? If the window.location command takes longer than a second to run, will it be interrupted by the meta refresh, or does it block that refresh? I am hoping the latter, so I don't need to increase the delay for those non-js people.
I figure my new way adds a little extra weight to the payload of the redirect, but it's not an extra round-trip or anything, is it? The redirect happens anyway, does it not? Update: I neglected to mention a very important point. I do not actually have control over the login screen itself, only the page it posts to. This code is part of a product that relies on an external authentication mechanism.
I'm working on an ASP.NET web application. There's a bill page which has two links to different pdfs of the same bill. When you click on one of the links it takes you to a ViewPDF.aspx page that shows the pdf. There's also an option to view both in a split screen so that you can compare them. When you click on this link it takes you to BillSplit.aspx which has a frameset and two frames that both point to ViewPDF.aspx. This all works perfectly.
The problem is that if an error occurs while pulling up the pdf. The application has an error page that has a few links back into the application. If you use one of these you can go back into the app and continue but now inside the frame. The URL still says BillSplit.aspx but the application is completely unaware of this since frames are HTML elements not asp.net controls.
What I would like to do at this point is detect that you've returned to the application and close the frame you aren't using. Essentially I'd like to redirect you away from BillSplit.aspx and to the page you're actually requesting. I'm pretty sure this would need to be done in Javascript either on the BillSplit page or on the pages that you go to later. So I guess what I'm asking is, is there a way to ensure that the BillSplit.aspx page and it's two frames point only at ViewPDF.aspx?
I have created an AJAX style file download (using an iframe) and all works well... however, I need to detect when the iframe has received a response... see below:
Javascript:
function download() {
var ifrm = $('#iframedownload')[0];
ifrm.src = '/downloadfile.aspx?fileid=whatever';
ifrm.onreadystatechange = function () { // Checking
if (this.readyState == 'complete')
alert("I would really like this piece to work!");
};
}
C# for downloadfile.aspx:
Response.AddHeader("content-disposition", "attachment; filename="" + zipFileName + """);
Response.AddHeader("Content-Length", respBytes.Length.ToString());
Response.ContentType = "application/octet-stream";
Response.BinaryWrite(respBytes);
Response.End();
I have developed a small script with some logic to check to see if an ASP.Net forms values have been updated since page load so that I can display a "You have unsaved changes" type message to the user if they attempt to close the browser window or more to another tab within the browser window.
The only control that I have not been able to hook upto with this script is the Cute Editor 3rd Party WYSIWYG text edit control. The control seems to be rendered using some smoke and mirrors involving iframes.
Now I have tried everything I can to hook the jQuery .change() and .keyup() events to this control as I have with all the other controls with no luck. I don't seem to be able to catch the changes or actually find the containing control that holds the text.
Basically I have a Search Text Box with a LinkButton Control on which the click event is fired. now what i want is when the user type keywords and press enter the Click event got fired. So No Javascript Only ASP.NET With VB.NET v2.0
View 2 RepliesI want to check if a mobile browser has javascript enabled before displaying a page to the user. The code I've found from my research is:
System.Web.HttpBrowserCapabilities browser = Request.Browser;
Response.Write(browser.EcmaScriptVersion.ToString());
So to ensure that javascript is enabled on a browser, you need to check wheather the returned valued is either equal to or bigger than 1. This works on normal browsers, but when I test it on my phone the returned value is always 0.0, no matter if my javascript is enabled or disabled. Is there a way to check if javascript is enabled on a mobile browser or will the browser handle the incapability on it's own?

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?
i am using a jquery image upload which works fine, when the image upload is complete i need to fire a serverside event is this possible?
View 16 RepliesIm using the following code:
jQuery(document).ready(function () {

It just doesnt fire. Anybody know why?
I am calling a javascript function on onfocus event of a multiline textbox and it is working fine.
But when I add HTMLEditorExtender to that multiline textbox onfocus event is not firing.
Here is my code

I am working on a feature to throw a warning message if the user has unsaved values in a form. I can see that in the next post there is a explanation about how to do that [URL]now the problem is that i need to do the same but using a ascx control and i don't know where put the next code in my ascx control.
<body onunload="checkSave()">
NB: I'm working on dnn so that i don't have any change to add this code in the parent page of the control.
I have a linkbutton to which i am binding to the click event using jQuery, however the page still posts back no matter what i try...
According to this i should be able to use event.preventDefault However nothing seems to work and it always posts back, but i do get the alert
Here is my example
<asp:LinkButton runat="server" Text="TEST" ID="lnkTest"></asp:LinkButton>
<script>
$(document).ready(function () {
var lnk = $('#<%=this.lnkTest.ClientID %>');
lnk.unbind('click.test').bind('click.test', function (event) { alert("Click"); event.preventDefault(); event.stopPropagation(); return false; });
});
</script>
UPDATE
Okay after some further investigation it seems that this does work as expected when i run it in a standalone page, however we are using this script, and it appears that it is causing a conflict..
That script moves any href='javascript:... into the click handler, im guessing that the order the handlers are assigned may have something to do with it...
I'm working on developing a custom control to select items from a predefined list. This is accomplished via 2 ASP.NET ListBox controls, with a few buttons to trigger the movement of ListItems from one ListBox to the other (lets call these ListBoxes lstSelected and lstDeselected).
This is easy enough to do in ASP.NET or JavaScript independently: I have both working. However, if modifications are made via JavaScript, ASP.NET retains no knowledge of this. Is there any way to register the creation of of options in a select tag without AJAX?

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.
View 1 RepliesThere 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:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script>[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 want to restrict the user if they select the language which is already selected by displaying alert msg using JQuery.
Is there any event which fires before the change event.
