jQuery trigger not firing with bind() or on() for custom events

由 你说的曾经没有我的故事 提交于 2019-12-14 00:18:09
问题 Can anyone tell me why this code would not be working? $('body').on('test', function() { alert('test'); }); $('body').trigger('test'); I'm using jquery-1.7.2.min . I do not get any errors, just nothing happens. I've tried putting the code inside an inline script, inside a $(document).ready() and still nothing. I've also tried both on() and bind() and neither result. I see examples all over showing the same syntax, so what is different with this? 回答1: It appears the issue lies in the DOM being

Actionscript 3.0 - Custom Events with Parameters

由 99封情书 提交于 2019-12-13 05:29:08
问题 Is there any simple -- or suggested -- way in order to send a parameter along with a custom event? Or even just a way to pass variables between two classes? My program is a sort of simple Civ/Age of Empires kind of game, where you can place buildings on tiles. This would work as follows: Player clicks on the icon on the HUD, which creates an dispatches an event which is received by the PLAYER class. The PLAYER class changes a value depending on which building is held (clicked on). Player

问题 I'm having a bit of issue with events in prototype. I'm trying to bind and fire the native events: onhashchange , and onpopstate . As well as my custom events: statechange and anchorchange . All these events are for the window element. Here's the code I've already tried with no luck: Element.observe(window,eventName,eventHandler); Element.fire(window,eventName); Any help would be appreciated. 回答1: You can only use fire for custom events. Take a look at this question/answer. I think it solves

How to trigger custom event with jQuery?

由 一世执手 提交于 2019-12-05 03:08:09
I'm attaching a custom event handler to the body in jQuery's ready method. Afterwards I immediately trigger the custom event but nothing seems to happen. $(function(){ $("body").on("test", function(){ alert("test triggered"); } $("body").trigger("test"); } Firstly you have a syntax error $(function(){ $("body").on("test", function(){ alert("test triggered"); }); < ---- Missing this $("body").trigger("test"); }); Secondly you cannot trigger the event from the console , as $(function() {}); forms a closure and you will not have access to any of the methods inside them For it to work like you are

问题 I would like to turn a primitive event (a click) into a semantic event, like "deleteTodo" This is described here, but not how to implement :( I have the following code: App.TodoView = Em.View.extend({ click: function(e) { this.trigger("deleteTodo"); } }); App.Router.map(function(match) { match('/').to('index'); }); App.IndexRoute = Ember.Route.extend({ deleteTodo: function(e) { // this code is never executed :( } }) ; After I perform the 'click', I see that the TodoView click function is

jQuery: How do I use event.preventDefault() with custom events?

由 回眸只為那壹抹淺笑 提交于 2019-12-02 17:55:55
How can I know in my triggering code that preventDefault has been called? $(document).trigger('customEvent', params); if (/* ??? */) doDefaultActions(); trigger() can also take an event object, so if you can create an event object, like so: var event = jQuery.Event("customEvent"); $(document).trigger(event); then you can check after the trigger to see if preventDefault() has been called like so: var prevented = event.isDefaultPrevented(); If you're asking how to find out whether or not the default has been prevented, use: event.isDefaultPrevented() This will return 'true' or 'false' based on

Kendo MVVM and binding or extending custom events

I have a ComboBox in my page and I want to bind keypress event to my Kendo ComboBox when the cliend writes down any letter. As I understand kendo doesn't have any keypress event on ComboBox. I've found that kendo has something like this to bind values and functions: kendo.data.binders.slide = kendo.data.Binder.extend({ refresh: function () { var value = this.bindings["slide"].get(); if (value) { $(this.element).slideDown(); } else { $(this.element).slideUp(); } } }); Source: Click Here But the problem is I can't workaround that and make it to trigger keypress event on the InputBox in the
