JavaScript CustomEvent
JavaScript events have been the gateway to user interaction within the browser since its inception. Not only do events tell us when an interaction happens, but events tell us type of interaction, the nodes involved, and provide us methods for working with the event. Creating custom events and triggering them have always been trickier. Using JavaScript's CustomEvent API, that trickery can be elimin

jQuery custom event 応用編 - monjudoh’s diary
前置き custom eventとは何か?(前置きの前置き) ブラウザがサポートしているeventではない独自定義event。 clickとかはブラウザがサポートしているevent ユーザのアクションやブラウザの状態等によって直接発火されることはない click eventは、ユーザがマウスポインタを要素の上に移動後にマウスのボタンを押すと発火される DOMContentLoaded eventは、ページのHTMLがダウンロード完了し、すべてパースされると発火される jQueryではtrigger,triggerHandler methodでeventをユーザのアクション等に関係なく発火することが出来る custom eventも発火出来る 逆に言うとcustom eventはJavaScriptの側からしか発火されない 以前The JUI 2009 Returnsで話をしました。 htt

Monitoring DOM properties – James Padolsey
I recently came across a jQuery plugin that claims to emulate the functionality of Object.prototype.watch, a method inherent in all objects that enables you to watch for a property change and run a function upon that change. Of course, this isn’t available in all implementations. IE, for example, doesn’t support this but has a DOM equivalent, onPropertyChange. Both methods are useful but their sli
Binding Events To Non-DOM Objects With jQuery
Yesterday, Dan G. Switzer, II was giving me some really great jQuery tips. Among the things that we discussed was the ability to define an anonymous function and then call it immediately: This is not jQuery specific, but the benefits of doing this is that you can create a totally private memory space in which to execute your anonymous function. In this memory space, locally declared variables won'
jQuery Create Event - Bind Logic to Dynamically Generated Elements | Eric Hynds - Website Developer
The livequery plugin allows us to bind events and general logic to all current and future elements. After the inclusion of live() in 1.3, an expansion of supported live event types in 1.4, and the introduction of delegate() in 1.4.2, the livequery plugin has more or less become deprecated. However, it still holds a special place in my heart because of it’s ability to listen for the creation of new

結構前から収集していた海外エントリから面白いcustom eventの使い方を紹介 - monjudoh’s diary
jQueryでは非DOMオブジェクトにもeventをbind/triggerできる Binding Events To Non-DOM Objects With jQuery この例だとwindow.location.hrefが変化しているかどうかTimerで監視し続け、 変化したタイミングで$( window.location ).trigger('change',data);で変更前後の情報を通知している。 なので、$( window.location ).bind('change',function(ev,data){});で通知を受け取る事ができる。 hashで状態を管理しているAjaxアプリで有効そうなテクニック。 select boxでcustom eventを活用 http://trulyevil.com/2009/05/07/custom-events-in-jquery/
Ben Alman » jQuery outside events: Why trigger an event on something, when you can trigger it on everything else?
jQuery outside events: Why trigger an event on something, when you can trigger it on everything else? With jQuery outside events you can bind to an event that will be triggered only when a specific “originating” event occurs outside the element in question. For example, you can click outside, double-click outside, mouse-over outside, focus outside (and over ten more default “outside” events). Also
Custom Events, and the Special Events API in jQuery | Envato Tuts+
Web pages, for the most part, are event-driven. Libraries such as jQuery have provided helper methods to make this functionality much easier to grasp. In this tutorial, we'll look at expanding upon these methods to create your own custom namespaced events. Events in JavaScript Before the luxury of JavaScript libraries, if you wanted to add a simple click event to an element you needed to do the fo
eventのグローバル通知 - monjudoh’s diary
jQuery.event.trigger(eventType); で、やる。若手ITゾンビで読んだ。 主な用途はDOM要素に紐づかないcustom eventの通知用(例：ajaxSend)と思われる。 (全DOM要素への通知って用途はあるのかな?) 実行すると、jQuery.cacheに入っている全てのオブジェクト(DOM要素に限らない)に対して、このeventを通知する。 なので、Ajax中にページ更新する際の注意点 - to-RのtipsでajaxSendをbindする対象はbodyでなくても良い。 ただし、jQuery.event.global[eventType]がtrueの場合(一度でもこのeventTypeのeventをbindしたことがある場合)のみ、この処理は行われる。 なので、例えばajaxSendを一度もbindしていなければ全cacheを舐めるような処理は行われない
Special scroll events for jQuery – James Padolsey
After recently considering the impact of a native DOM implementation of two possible scroll events; “scrollstop” and “scrollstart”, I eventually came to the realisation that it would probably be a bad idea. Consider these two potential events yourself – what would initiate the “scrollstop” event? – how does the browser know when a user has stopped scrolling; it can’t just fire the event on every s
Firing Custom Events in jQuery | Truly Evil
Events seem daunting at first, but really jQuery makes them super simple. Events can be used to alter behavior or even have multiple events happen on a single state change. We all know about events like click, onkeydown, onmousedown, onmouseover, etc. But you can fire custom events as well. First you need to understand how to fire events. You can do this by using the $().trigger() event through jQ
Ajax中にページ更新する際の注意点
Ajax中にページ更新する際の注意点 Ajaxで通信中にF5などを押してページをリロードすると通信エラーが帰ってきます。 詳しくは調べていませんが、どうもFirefoxでの挙動のようです。 参考：FirefoxでAjax中にF5押したとき « pocketo.net blog このサイトのようにAjaxのXMLHttpRequestをabort()で中断すれば、この問題は解決できます。 var xhr = $.ajax( {....}) $( document ).bind( 'beforeunload', function() { xhr.abort(); } ); ただ、通信の数が多い場合は、毎回設定するのは少し面倒。 そういう場合は、以下のように設定しておくとjQueryでajaxを使うと自動でabort()を設定してくれます。 $("body").bind("ajaxSend",

jQuery idleTimer plugin - Paul Irish
There are a few cases where you want to know if the user is idle. Namely: You want to preload more assets You want to grab their attention to pull them back You want close their banking session after 5 minutes of inactivity. (Jerk!) You want the site to sneak off the screen and see if they notice ;-) Nick Zakas wrote a script for YUI3 to handle these cases. His writeup has a great description of t
