event-handling

问题 I'm about to build a simple "mortgage calculator" where a user is to adjust some sliders OR edit values in input fields in order to calculate some final value based on the provided data. Schematically it will look something like this: Slider1 - Input1 Slider2a - Input2a Slider2b - Input2b The idea is that the value of the input must be reflected in the slider, and vice versa. In addition, the values and limits of slider 2a/2b and input 2a/2b depend on each other, according to some simple rule

问题 My goal is to write an java applet application that writes a word document(this document is fetched from DB)in a temporary directory on client machine and opens that document using Jacob. Through Jacob I need to keep the handle to the opened document, so that after the user closes the document I need to save it back to the DB with the changes. That said, the first thing I want to know is how to capture a close/exit event through Jacob when the user closes/exits the MS Word document . How can

问题 There are ways of registering Events to objects in an HTML file. So this way an object is set to detect events. In case we think 2 div elements one inside other; If i attach an onClick event to inner div; this means outer div was not attached one. So it should NOT detect the click event. Why still we need to use stopPropagation () ? since we did not attach any other event detection... 来源： https://stackoverflow.com/questions/43953228/why-we-need-to-use-stoppropagation-in-javascript-events

问题 I have a simple event handler: jssor_slider1.$On($JssorSlider$.$EVT_CLICK, function (slideIndex) { jssor_slider1.$PlayTo(slideIndex - 4, [200]); }); I have a problem trying to unbding it (i need to disable it in a different function, then enable it again on callback - when ajax loads). I tried $Off, also overwriting $On handler, but can't get it to work. Any help would be appreciated. Cheers 回答1: function SliderParkEventHandler(slideIndex) { jssor_slider1.$PlayTo(slideIndex - 4, [200]); }

问题 I am practicing on implementing a MMF as IPC, I have tried it via wpf as listener and set it's event handler which does trigger. Now that I have moved the same setter code into a Wpf (the setter till that point was Console App) on the Wpf App I could not get the event handler to fire. this is the code I have successfully implemented and I am not sure if this implementation is right, ...the only thing I ma sure of is that it sends data, receives a reply(from wpf actually) and fires its event(

问题 I am working on a small project (with NetBeans' Java GUI Builder) in which I have 100 TextFields which does exact same thing on different data . They are arranged in 10 rows and 10 columns , there (Variable) names are like: txt11, txt12, ... txt110 txt21, txt22, ... txt210 . . ... . txt101, txt102, ... txt1010 so, that there names can easily generated by the row and column number as well as I can easily extract the row and the column of a TextField to which it belongs (But I can not).

问题 I use the below code to verify if the text into a TextBox was changed and ask for saving changes: Private TBoxTxtBefore As String = String.Empty Private Sub TextBox1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Enter Try TBoxTxtBefore = CType(sender, TextBox).Text Catch ex As Exception MsgBox(ex.ToString) End Try End Sub Private Sub TextBox1_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Leave Try If CType(sender, TextBox).Text <>

My intent is to feign scrolling by adjusting top offset until div inside of div is above view then move top offset of inner div to below view of outter div . Kind of like a carousel, but vertical and controlled by scrolling of the mouse wheel. Obviously, to catch scroll events, I would use angular.element(elem).find('.divClass').bind('scroll', function(){...}); to handle scrolling that is

问题 In this question Cloning a bootstrap element with an event listener I asked how to clone an element without copying the bootstrap-supplied event listener. And the answer is to not pass true to the clone() command. As it turns out, I see now that my problem is a bit more complicated than that. What I actually have is a div containing several buttons, one of which controls the expand/collapse of an associated div, and others of which provide other specialized functionality, which are provided
