问题 I have a JTable in which I want to call a function when a cell is double-clicked and call another function when the cell is triple-clicked. When the cell is triple-clicked I do not want to call the double-click-function. What I have right now is (mgrdAlarm is the JTable) : mgrdAlarm.addMouseListener(new MouseAdapter() { public void mouseClicked(MouseEvent e) { System.out.println("getClickCount() = " + e.getClickCount()); if (e.getClickCount()==2) { doubleClick(); System.out.println("Completed

问题 When I was trying to disable the right click, it is not working. I tried with below code. document.onclick = function(e) { console.log(e.button); if(e.button == 2){ e.preventDefault(); return false; } } Based on below link only I tried. Disable Right Click in website I tested this code in Chrome and Firefox. Every time I am getting the right output only in console. I mean "0" for left click and "2" for right click.But still the default action is happening. May I know the reason.? Thanks in

问题 Can someone explain to me why actual mouse click and $('div').click() runs click event 3 times while $('div')[0].dispatchEvent(new MouseEvent('click')) runs click event only 1 time according to browser console? Here's a simple html code: <div>test</div> Here's a javascript code: $('*').click(function(e){ console.log(e); }); var c = new MouseEvent('click'); // Actual mouse click output event 3 times //$('div').click(); // output event 3 times $('div')[0].dispatchEvent(c); // output event 1

问题 So I want to fire a function only once every time a user scrolls up or down via the Mousewheel. See: jsFiddle Demo. The issue is that even though I have the e.preventDefault(), the function still fires multiple times. The goal is for the function to fire only once whenever a user scrolls up or down. Similar to this site. Here is the code that I have so far: var sq = {}; sq = document; if (sq.addEventListener) { sq.addEventListener("mousewheel", MouseWheelHandler(), false); sq.addEventListener

问题 I'm trying to do a very simple button that changes color based on mouseover, mouseout and click, I'm doing this in prototype and the weird thing is if I used mouseover and mouseout, after I clicked on the button, the button wouldn't change to white, seems like it is because of the mouseout, here's my code $("izzy").observe('mouseover', function() { $('izzy').setStyle({ color: '#FFFFFF' }); }); $("izzy").observe('mouseout', function() { $('izzy').setStyle({ color: '#666666' }); }); $("izzy")

问题 I want to handle MouseEnter event for a Custom Control when control is disabled. Is there a way to handle it? 回答1: The documentation for UIElement.IsEnabled documents the behaviour you see: Elements that are not enabled do not participate in hit testing or focus and therefore will not be sources of input events. The logical conclusion, to me, is that if you do want to handle mouse events, you don't disable the control. Instead, use some other method of achieving what you want. For example, if

问题 I am trying to make textbox similar to the Twitter , for this i have written code for Word Count Used Events Change, Keyup and Paste Keyup and Change Events are working fine but paste event is little bit strange, when i paste something in textarea the word count doesn't change at that moment, after some debugging i found that paste event fires up before pasting something on textbox . I don't know how they handle this in Twitter. Here is my code : events: 'click #textboxId' : 'submitQuestion'

问题 If I want to mouseenter a div, an element will show, then when mouseleave, element disappears. I have a click function inside the mouseenter so theres a drop down menu when clicked. I want the dropdown menu and the element to stay active even when mouseleaves. So I want mouseleaves to not be applicable in this situation, when there's a click event. User will have to click on the element again or anywhere on the page to make the element and dropdownmenu disappear. But I want to keep mouseleave

问题 Is there an operating system neutral way for Ruby to send keyboard and mouse events to the underlying operating system? One obvious (to me) approach is to use the Ruby/Java bindings and use java.awt.Robot, but that just seems silly. 回答1: For Mac: gem install rb-appscript Then you can test it with a script like this: require "rubygems" require "appscript" include Appscript app("TextEdit").activate app("System Events").keystroke("Look Ma, keystrokes!") For Windows: (untested, borrowed from this

问题 I have a body system feature I'd like to implement. When the user hovers over a body part, it highlights and shows information on that specific body part. I've coded the CSS the way I want it, but I don't know anything about JavaScript to get the information to stick when the body part is clicked or the mouse leaves the hover state. I've searched the forum and found similar issues and have spent hours trying to figure this out myself from others' javascript solutions - I'm at the point where
