unbind

问题 Does TkInter unbind function prevents the widget on which it is applied from binding further events to the widget ? Clarification: Let's say I bound events to a canvas earlier in a prgram: canvas.bind("<Button-1>",some_function) Then at a certain point of the program, we no longer need those events: canvas.unbind("<Button-1>") Can we later do something like this: canvas.bind("<Button-1>",OTHER_function) 回答1: No, unbinding an event doesn't prevent further bindings on the widget. You can bind

问题 I have checked multiple similar posts on SO but haven't yet found the answer. I have a Google map app that when you Zoom in the marker changes from an icon to a circle. It works great. The Marker icon is replaced by the circle object. But, I also want it to work in reverse: As you zoom out, I want to remove the circle and replace it with the icon. I can get the icon to "reappear" but I can't figure out a way to get a reference to the circle object that is bound to the Marker so I can remove

问题 I made this piece of code,i'm trying to animate a block of text/div back and forward, but why this works only the first time for the "placeRight" function? Is there something wrong with the right : "+=750" attribute? $(document).ready( function ( ) { $("#text").click(placeRight); }); var placeRight = function() { $("#text").animate( { right : "+=750" }, 1300); $("#text").unbind("click"); $("#text").click(placeLeft); } var placeLeft = function() { $("#text").animate( { left : "+=750" }, 1300);

问题 So I am making a little quiz, with a I want to disable the click for everything inside #qWrap while the animation is operating, thus preventing spamming clicks. I tried to use .is(':animated') but to no effect. Any ideas? HTML: <div id="qWrap"> <ul id="qBox"> <!--Q1--> <li id="q1" class="qContainer"> <ul class="qAnswers"> <li class="qQuestion"> <h3>What are italics?</h3> </li> <li> <a href="#q2" class="mums"> <h3>Slanted cut of a type</h3> </a> </li> <li> <a href="#q2" class="such"> <h3>A

问题 It's a common problem that jQuery widgets inside ASP UpdatePanels need to reinitialized after an ajax request, however my issue is that events are not unbound prior to replacing the HTML inside the UpdatePanel. jQuery takes care of this problem for you whenever you call .html("...") or .remove(), but the UpdatePanel doesn't utilize jQuery. I have popup elements (inside of the UpdatePanel), which need to be hidden when the user clicks outside of them so I made a jQuery Special Event for

问题 i want to disable the click handler when the toggle animation is showing so the animation won't build up because of multiple fast click. thanks jquery script: $("#button").click({ $(this).unbind('click').next().toggle("slow",function(){$('#button').bind('click')}); }); html code <div <a href='#' id='button'>Toggle</a> <div> test </div> </div> 回答1: As mentioned your implementation of event attachment is broken. On top of that there is a method in jQuery called .stop which releases you from

问题 I have an Android application that is binding to a persistent service (once started with startService() ). The service is an integral part of the application and thus is used in almost every Activity. Hence I want to bind to the service just once (instead of binding/unbinding in every Activity) and keep the binding during the lifetime of my application. I've extended from Application and bind to the service in Application#onCreate(). However I now have the problem that I don't know when my

问题 I am using the jQuery tablesorter (http://tablesorter.com). After being applied to a table by $('#myTable').tablesorter() , how can I remove it again from the table? 回答1: There isn't a built-in function to do this, but you could remove the class names and event bindings to stop its functioning... try something like this: $('table') .unbind('appendCache applyWidgetId applyWidgets sorton update updateCell') .removeClass('tablesorter') .find('thead th') .unbind('click mousedown') .removeClass(
