问题 Check out my jsfiddle demo, if e.which == 1 then when you left click the h2 it will e.which == 2 or e.which == 3 then it wont work. 2 is the middle mouse button, and 3 is the right mouse button. i found this too: JQuery provides an e.which attribute, returning 1, 2, 3 for left, middle, and right click respectively. So you could also use if (e.which == 3) { alert("right click"); } This code isn't working: code: $("h2").live('click', function(e) { if( e.which == 2 ) { e.preventDefault(); alert(

get click event of each rectangle inside canvas?

问题 I dont know how to register click event on each rectangle. here is the sample: http://jsfiddle.net/9WWqG/1/ 回答1: You're basically going to have to track where your rectangles are on the canvas, then set up an event listener on the canvas itself. From there you can take the coordinates of the click event and go through all your rectangles to test for 'collisions'. Here's an example of doing just that: http://jsfiddle.net/9WWqG/2/ html: <canvas id="myCanvas" width="300" height="150"> </canvas>

由 耗尽温柔 提交于 2019-11-26 13:47:09
I made buttons in pygame for click events, but there is a problem. When I click the mouse button and move the mouse between the button boundaries, the click event is repeating itself. I just want a single click until I release the mouse button. How can I do that? import pygame,time pygame.init() x,y = (200,300) pencere = pygame.display.set_mode((x,y)) pygame.display.set_caption("Click") white = (255,255,255) black = (0,0,0) black2 = (30,30,30) class Counter: count = 0 def click(self): self.count += 1 number = Counter() def text_objects(text, font, color): textSurface = font.render(text, True,

Add and remove a class on click using jQuery?

由 痞子三分冷 提交于 2019-11-26 13:22:01
Please see this fiddle . I am trying to add and remove a class on li elements that are clicked. It is a menu and when one clicks on each li item I want it to gain the class and all other li items have the class removed. So only one li item has the class at a time. This is how far I have got (see fiddle). I am not sure how to make the 'about-link' start with the class current, but then it is remove when one of the other li items are clicked on? $('#about-link').addClass('current'); $('#menu li').on('click', function() { $(this).addClass('current').siblings().removeClass('current'); }); Why not

问题 My HTML: <div id=\"x\" onclick=\"clickHandler(event)\"> <div id=\"button1\">This turns green</div> <div id=\"button2\">This turns blue</div> </div> So first of all, why am I supposed to be passing \"event\" into the click handler and is event some kind of system keyword? Also, since the click handler is identified on the container div, how do I know which button has been clicked? 回答1: event is an Event object which is created automatically when an event is fired. Note that you don't have to

How to remove all Click event handlers in Jquery

由 試著忘記壹切 提交于 2019-11-26 12:57:23
问题 I\'m having a problem. Basically, when a user clicks an \'Edit\' link on a page, the following Jquery code runs: $(\"#saveBtn\").click(function () { saveQuestion(id); }); By doing this, the onClick event of the save button calls the saveQuestion() method and passes on the ID of the question for which the \'Edit\' link was clicked. But if in the same session the user clicks edit on 2 questions, then instead of overwriting the previous click event handler, it instead causes 2 event handlers to
