Live events don’t follow the same event bubbling rules. See the documentation on live event handling. Quote from reference above: Live events do not bubble in the traditional manner and cannot be stopped using stopPropagation or stopImmediatePropagation. For example, take the case of two click events – one bound to “li” and another “li a”. … Read more
http://docs.jquery.com/Events/unload#fn jQuery: $(window).unload( function () { alert(“Bye now!”); } ); or javascript: window.onunload = function(){alert(“Bye now!”);}
It’s weird that nobody offered an alternative solution that uses event bubbling function callback(e) { var e = window.e || e; if (e.target.tagName !== ‘A’) return; // Do something } if (document.addEventListener) document.addEventListener(‘click’, callback, false); else document.attachEvent(‘onclick’, callback); The pros of this solution is that when you dynamically add another anchor, you don’t need to … Read more
Create a dummy window that does nothing but wait for WM_DEVICECHANGE and register that window using RegisterDeviceNotification. WMI is an overkill here, IMHO.
A brief example on how to expose an event from the UserControl that the main window can register: In your UserControl: 1 . Add the following declaration: public event EventHandler UserControlClicked; 2 . In your UserControl_Clicked event raise the event like this: private void UserControl_MouseDown(object sender, MouseButtonEventArgs e) { if (UserControlClicked != null) { UserControlClicked(this, … Read more
Cache the width of the viewport and on resize return false if the width is still the same. A small jQuery snippet: var cachedWidth = $(window).width(); $(window).resize(function(){ var newWidth = $(window).width(); if(newWidth !== cachedWidth){ //DO RESIZE HERE cachedWidth = newWidth; } });
If you want key repeat in a controllable fashion, you will have to implement it yourself, as keypress events are fired dependent on the OS’s idea of how keys should repeat. That means there may be variable initial and following delays, and holding down two keys at once will cause only one of them to … Read more
jQuery is not going to solve this one OOTB. It can help, but none of stopPropagation, stopImmediatePropagation, preventDefault, return false will work if you simply attach them to the element. You need to override the element’s click handler. However you state in your question “without removing onclick actions”. So you need to override the default … Read more
Using Oracle you can setup a Trigger on a table and then have the trigger send a JMS message. Oracle has two different JMS implementations. You can then have a process that will ‘listen’ for the message using the JDBC Driver. I have used this method to push changes out to my application vs. polling. … Read more
To differentiate between scroll up/down in jQuery, you could use: var mousewheelevt = (/Firefox/i.test(navigator.userAgent)) ? “DOMMouseScroll” : “mousewheel” //FF doesn’t recognize mousewheel as of FF3.x $(‘#yourDiv’).bind(mousewheelevt, function(e){ var evt = window.event || e //equalize event object evt = evt.originalEvent ? evt.originalEvent : evt; //convert to originalEvent if possible var delta = evt.detail ? evt.detail*(-40) : … Read more
