Sending My Own Arguments To A Event Handler?

阅读更多关于 Sending My Own Arguments To A Event Handler?

问题 I'm working with AssemblyResolve specifically. Here is my code first, then my question follows: var a = AppDomain.CurrentDomain; a.AssemblyResolve += new ResolveEventHandler(HandleIt); Private Assembly HandleIt(object sender, ResolveEventArgs args){ //Does stuff, returns an assembly } So I add HandleIt to my AssemblyResolve event. How can I add it to that event and pass an argument with it like: a.AssemblyResolve += new ResolveEventHandler(HandleIt(AnArgument)); This is throwing me off since

阅读更多关于 JQuery Event.target problem in ie7

Trying to accses the class name from the event.target object. Works in FF, Safari, and Chrome. InternetExplorer 7 alerts "undefined". Any suggestions? <script type="text/javascript"> $("document").ready(function(){ $(".page").hide(); $(".page:first").show(); $("#navBar a").bind("click", linkClicked); }); function linkClicked(event){ $("div.page:visible").fadeOut(250, function(){ var $target = $(event.target); alert($target.attr("class")); //$("#" + $(event.target).attr("class")).fadeIn(250); }); } </script> Found a solution. Set the event.target to a var before the callback for fade out. :p

Initiate onclick faster than with document.onload

阅读更多关于 Initiate onclick faster than with document.onload

I have html-pages with links where i want to attach a function to their onclick-event. One way to do it is of course: <a href="save.php" onclick="save(); return false;" rel="save">Save</a> But I know this is not the best practice. So instead I wait for window.onload, loop through the links and attach the save-function to the links with rel="save". The problem with this is that it waits until the whole page has finished loading which can be several seconds after the link is displayed and clickable. So is there another way to do this? Avoiding onclick in the html but that makes it work

Removing a Vue custom filter on mouseover

阅读更多关于 Removing a Vue custom filter on mouseover

I would like to remove a truncate filter on mouseover using VueJS 2. Here is my filter in the template: <div class="eng" @mouseover="showAll">{{ word.english | truncate }}</div> And here is the filter itself: filters: { truncate: function(value) { let length = 50; if (value.length <= length) { return value; } else { return value.substring(0, length) + '...'; } } }, Is there a way to remove the filter on the mouseover event so that the div is not truncated anymore? Thanks! Edit: The showAll() function is where I thought I would remove it. I tried a couple ways to remove the filter such as:

ItemAdd event on a public folder on Exchange

阅读更多关于 ItemAdd event on a public folder on Exchange

问题 I have a problem with attaching an event handler to an ItemAdd event of a public folder. The problem is the event handler stops being called after a few successful calls. The code is trivial. I have a ThisAddIn class which creates an object which in turn attaches a function to the ItemAdd event in its constructor. The function just pops up a messagebox. Please point me in the right direction. I simply don't understand where to look for the error. Thank you in advance, Anatoly Here is the test

Design Help – Polymorphic Event Handling

阅读更多关于 Design Help – Polymorphic Event Handling

问题 Design Question – Polymorphic Event Handling I’m currently trying to reduce the number of Event Handles in my current project. We have multiple systems that send data over USB. I currently have a routine to read in the messages and parse the initial header details to determine which system the message came from. The headers are a little different, so the EventArgs I created are not the same. Then I notify all “observers” of the change. So what I have right now is the following: public enum

How do I run a function on a specific key press in JavaFX?

阅读更多关于 How do I run a function on a specific key press in JavaFX?

I have a program in javafx that is running and I want to call a function inside that program when a specific key is pressed on the keyboard (for example, the "a" key). I tried using an event handler on my scene but KEY_PRESSED seems to go off when any key is pressed, unless I am using it wrong. KEY_TYPED seems like it might suit my needs, but I've only found examples of that one in relation to text boxes, which is not what I'm looking for. Does anyone know how to do this, or have a good resource I can consult for something like this Just check the code of the key that was pressed: scene

问题 I've got a jquery code, which $("a.reply").click(function() { //code }); When I click the link with .reply class the first time, nothing happens.
