jQuery cycle with pager inside div with click events - can't stop propagation

由 陌路散爱 提交于 2019-12-20 06:11:23
问题 I'm using the jQuery Isotope plugin. In each clickable (maximising/minimising) Isotope element, I'm having one jQuery Cycle slideshow generated like $('.slideshow.mainview').each(function () { var $pager = $('<div class="pager"></div>').insertAfter(this); // creates a pager for each slideshow $(this).cycle({ speed: 300, timeout: 0, pager: $pager, pagerEvent: 'click', allowPagerClickBubble: false }); }); Clicking on a pager link closes the Isotope element, so one can't see the next slide :(

问题 I'm trying to detect mousemove events on partially overlapping SVG elements, as in this image fiddle <svg> <rect id="red" x=10 y=10 width=60 height=60 style="fill:#ff0000" /> <rect id="orange" x=80 y=10 width=60 height=60 style="fill:#ffcc00" /> <rect id="blue" x=50 y=30 width=60 height=60 style="fill:#0000ff; fill-opacity: 0.8" /> </svg> $('rect').on('mousemove', function() { log(this.id); }); Now, when hovering the mouse over the blue/red intersection I'd like to detect mouse events on both

Event Bubbling, and Stop Propagation

由 你离开我真会死。 提交于 2019-12-17 20:08:32
问题 What is the difference between event.bubbles to false for any event, and setting event.stopPropagation() or stopImmediatePropagation() while handling event? I'm using Flex4 with AS3. 回答1: Setting bubbles to false means the event does not bubble up the display list at all. stopPropagation() and stopImmediatePropagation() make the current event listener the last to process an event. The difference between stopPropagation() and stopImmediatePropagation() is that stopImmediatePropagation() will

React prevent event bubbling in nested components on click

由 倖福魔咒の 提交于 2019-12-17 04:52:51
问题 Here's a basic component. Both the <ul> and <li> have onClick functions. I want only the onClick on the <li> to fire, not the <ul> . How can I achieve this? I've played around with e.preventDefault(), e.stopPropagation(), to no avail. class List extends React.Component { constructor(props) { super(props); } handleClick() { // do something } render() { return ( <ul onClick={(e) => { console.log('parent'); this.handleClick(); }} > <li onClick={(e) => { console.log('child'); // prevent default?

QML - Can't get mouse released event when I don't accept mouse pressed event

由 廉价感情. 提交于 2019-12-12 13:34:06

AngularJS: How to stop event propagation from ng-click?

由 拥有回忆 提交于 2019-12-12 07:53:48
问题 I have directive that does something like so: app.directive('custom', function(){ return { restrict:'A', link: function(scope, element){ element.bind('click', function(){ alert('want to prevent this'); }); } } }); yes, it's necessary to do jQuery-way binding for this case. And now I want to stop this event(click) propagation if some condition met. Tried to do: $event.stopPropagation(); $event.preventDefault(); but it did not help. here fiddle for example - http://jsfiddle.net/STEVER/5bfkbh7u/

angularjs Treeview using ng-include fires ng-click for all node's parents

由 对着背影说爱祢 提交于 2019-12-12 03:24:16
问题 I want to write treeview using angularjs . I am using ng-include for recursive call..everything is fine except from ng-click ..when each node is clicked..the hierarchy call is from child to it's parents and for every node in this hierarchy the ng-click fires. how can i solve this problem??..I have this exact problem using another approach (appending element on post-link which I think is not a good way) instead of ng-include . here is my code: index.html: <!doctype html> <html> <head> <script

JavaScript: Is there any performance benefit to stopping event propagation?

由 ∥☆過路亽．° 提交于 2019-12-10 12:17:59
问题 Is it considered 'good practice' to stop JavaScript event propagation - does it benefit performance in any way? I'm wondering if there is benefit outside of layout purposes where you stop propagation so you don't trigger multiple events accidentially. 回答1: Only when it is necessary to the program logic, such as to prevent form submission or another DOM element's action being triggered. Unless you have a seriously complex DOM tree, there will not be any serious performance hit. 回答2: It
