jquery-ui: immediate draggable on mousedown

由 我们两清 提交于 2019-12-11 04:16:07
问题 Working with jQuery-UI, it is possible to make an element draggable by applying .draggable() method on mousedown event. And then drag it on another mouse press (and drag). Is it possible to make element draggable and start dragging immediately by single mouse press (mousedown event). What happens : 1) press blue rect and try to drag (element not movable); 2) unpress rect and try to drag again (element is movable). What should happen : 1) press blue rect and drag it --> element is movable. <

Jquery on mousedown not working on dynamically generated elements

问题 So i'm trying to create a js/css "wave game" like tower defense ones. When all the pre-generated enemys from first wave are dead, it spawns the second wave and so on. So far so good. The problem is that i just can't attack mobs dynamically spawned within second wave. I used to try .live() in similar cases, but its deprecated, so i'm trying .on(), as instructed $('.enemy').on('mousedown' , function(event) { //attack code } Its working fine for initial mobs (1st wave) but it still just not

mouse:down vs. mousedown in fabric.js

问题 Here is a fabric.js example with a canvas and a rectangle, with a mouse down handler on each: var canvas = new fabric.Canvas('c'); var rect = new fabric.Rect({ left: 100, top: 100, width: 50, height: 50, fill: '#faa', }) canvas.add(rect); canvas.on('mouse:down', function(options) { console.log('canvas event'); }); rect.on('mousedown', function(options) { console.log('rect event'); }); Why does it need to be mouse:down on the canvas, but mousedown on the rectangle? If I change either, they

MouseDown and Click conflict

由 泪湿孤枕 提交于 2019-12-10 12:55:36
问题 I have a Drag() method on form_MouseDown event. I also have a click event on the form. The problem is that if I click on the form, MouseDown event gets triggered and it never gets the chance to trigger click event. What is the best way to solve this issue? I was thinking counting pixels if the form is actually dragged, but there has to be a better way. Any suggestions? 回答1: I was thinking counting pixels if the form is actually dragged, but there has to be a better way. Nope, that's exactly

Mouseup and Mousedown

问题 So I want the buttons to change style when mouse is down, and return to previous when it goes up. I have this code: $('#divMenu > #menu li a').mousedown(function(){ $(this).css({ 'font-size': '25px', 'color': 'red' }); }).mouseup(function(){ $(this).css({ 'font-size': '30px', 'color': 'black' }); }); The problem is, that when I have mouse down, but take it away of my object and not release immediately, font size and color stays 25px and red. What should I do to pass that? EDIT: JsFiddle here:

When are tunneling and bubbling events useful in WPF?

由 ↘锁芯ラ 提交于 2019-12-06 19:23:45
问题 I understand how bubbling and tunneling works. However, i'm confused about using them. Here is why: I want to handle a mouse click event. To bubble it, there is MouseDown and, to tunnel it, there is PreviewMouseDown . However, MouseDown doesn't necessarily mean the user clicked the control. May be the user pressed the button and moved away from it to cancel the click. I wouldn't want to change anything if the button is not being clicked. So my question is, how are the Bubbling/Tunneling
