问题 This question already has an answer here : Using special auto start servlet to initialize on startup and share application data (1 answer) Closed 4 years ago . I'm trying to get a J2EE server to register (read: send some message to) with another server on its own initiative - not as a response to something. Surprisingly, I've found very little information or questions on whether there are events and/or classes to extend that will give me a handle on "server-start". I could always write a

Use of ckeditor “key” CKEDITOR.instances.editor.on('key', function (e){

问题 I realize there are questions about how to implement an event handler for CKEDITOR 4. I am able to use this code to get the key-down data, but I can't seem to get the data after a key-up: CKEDITOR.instances.editor.on('key', function (e){ document.getElementById("preview").innerHTML = CKEDITOR.instances.editor.getData(); }); So when I type a string like "aaa" into the text editor field, the first character is never fetched. So my div id="preview" will only show "aa". I've iterated over the e

Multiple jQuery events on one element with different functions and target selectors

问题 Is there a way to combine these two methods of handling the event attachment in jQuery? $('selector').on({ mouseenter: function() {}, mouseleave: function() {}, mousedown: function() {}, mouseup: function() {} }); I prefer the previous method but need something like the following to work with "live"-events (the problem is that this will not work if there's a comment between the handlers): $(document).on('mouseenter', 'selector1', function(){}) .on('mouseleave', 'selector2', function(){}) .on(

Matplotlib event_handling line picker

由 喜你入骨 提交于 2019-12-22 07:57:23
问题 This example makes it possible to click a legend and thereby change a plot. I want to do something similar, but then not by clicking the legend, just by clicking the line in the plot. I tried to do it like this: self.ax = self.fig.add_subplot(1,2,1) data = NP.array(2,10) #filled with numbers self.x = NP.arange(2) for line in range(len(data[0,:])): self.ax.plot(self.x, data[:,line], picker=5) In every loop, an extra line is plotted. One line consists of 2 points, so it draws a straight line.

This is the problem code snippet. $(document).ready(function(){ $('.test').datepicker(); ... $('.test').datepicker('option', 'onSelect', function

How WinRT events are interoperate with .NET

问题 In the latest video by Rx team Bart De Smet: Rx Update - .NET 4.5, Async, WinRT I saw that WinRT events exposed to .NET by some really strange metadata, more preciesly - add_ / remove_ pair methods signature: EventRegistrationToken add_MyEvent(EventHandler<MyEventArgs> handler) { … } void remove_MyEvent(EventRegistrationToken registrationToken) { … } It looks really great, allowing unsubscribing from event by "disposing" the registration token (Rx does the same kind of thing, returning
