event-handling

In JavaScript I am using click event to change chart data. Below is a method for click event. $('#pro1').click(function () { chart.series[0].update({ data: pro1 }); }); $('#pro2').click(function () { chart.series[0].update({ data: pro2 }); }); $('#pro3').click(function () { chart.series[0].update({ data: pro3 }); }); I need to minify these three click events in one event, means I want to write one click event which handle the id's. some thing like below code. $('#pro'+i).click(function () { chart.series[0].update({ data: pro+i }); }); I don't know how to do it exactly. The above code is not

I am very new to python. I was trying to pass value from one method to another within the class. I searched about the issue but i could not get proper solution. Because in my code, "if" is calling class's method "on_any_event" that in return should call my another method "dropbox_fn", which make use of the value from "on_any_event". Will it work, if the "dropbox_fn" method is outside the class? I will illustrate with code. class MyHandler(FileSystemEventHandler): def on_any_event(self, event): srcpath=event.src_path print (srcpath, 'has been ',event.event_type) print (datetime.datetime.now())

What is the exact difference between Bubbling Events and Tunneling events? Where should I use Bubbling Events and where should I use Tunneling events? Thanks in Advance! Joetjah WPF gives us a number of different mechanisms for handling events – they are bubbling, tunneling, and direct. These are all known as Routed events. Direct event You are probably already used to the direct routed event. This is where the item itself handles the event that occurred. A good example would be handling he onClick -event of a mouse button in standard WinForms. This is where the event is raised in the GUI item

I want to attach a event to dynamically created element class.So i used live function but it was not triggered. So checked live function reference ,there i red below notes As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live(). so decide to use on function,But it still not working.The text field is already attached with jquery ui datpicker.On another element select i disabled that field. jQuery("#from").attr('disabled','disabled') .removeClass('date_picker_bg') .removeClass(

I have written an SWT UI which has a primary function of displaying text in a StyledText control. I want to add a handler for Ctrl + F so that when that shortcut is pressed the focus is set to a search box. I have tried using the following code to detect the keypress. sWindow = new Shell(); ... sWindow.getDisplay().addFilter(SWT.KeyDown, new Listener() { @Override public void handleEvent(Event e) { System.out.println("Filter-ctrl: " + SWT.CTRL); System.out.println("Filter-mask: " + e.stateMask); System.out.println("Filter-char: " + e.character); } }); I was expecting that when I pressed Ctrl +

Say we have the following method: private MyObject foo = new MyObject(); // and later in the class public void PotentialMemoryLeaker(){ int firedCount = 0; foo.AnEvent += (o,e) => { firedCount++;Console.Write(firedCount);}; foo.MethodThatFiresAnEvent(); } If the class with this method is instantiated and the PotentialMemoryLeaker method is called multiple times, do we leak memory? Is there any way to unhook that lambda event handler after we're done calling MethodThatFiresAnEvent ? Yes, save it to a variable and unhook it. DelegateType evt = (o, e) => { firedCount++; Console.Write(firedCount);

Allright, SO i have an input box and I need to do things everytime it changes, I am having trouble doing it for mouse paste. Here is the code I have $("#attack-navy"+unit.ID+"-number").bind('paste', function(){ alert("paste detected"); $("#attack-max-capacity").text(getMaxCapacity()); }); the getMaxCapacity() function return number entered * 30 for now; Here is the scenario when 1: I paste 3, it will not change (i still see the alert) 2: Then when i paste 5, it will be 90(3 * 30) 3: Then if i paste 10 it will be 150(5 * 30), and so on. I think its doing the handler before the paste actually
