由 拈花ヽ惹草 提交于 2019-12-12 03:44:38
问题 First of all drag and drop works correctly in my stages in version 4.3.0, so I just want to understand why I get the following problem with 4.3.3. I have three stages. One sits in a container in a document in an iframe. The others sit in containers in the iframe's parent document, one displaying a complex layout of shapes and the other a single simple shape for testing. The document in the iframe which controls all the action has a viewfinder overlay that drags and drops correctly. However

问题 I use the angular-drag-and-drop-lists directives to handle drag and drop operations. I populate groups separated from the actual items. Problems occurs when I drag the item onto the ul element, item disappears. Here is a link to a plunker for you to be able to see what I mean. Below is my code: <ul ng-repeat="group in groups" class="groups" dnd-list="items"> <li class="title">{{group.name}}</li> </ul> <ul class="items"> <li class="item" ng-repeat="item in items" dnd-draggable="item" dnd-moved

How to drop texts and images on a canvas? (Firefox 41.0.1)

由 自闭症网瘾萝莉.ら 提交于 2019-12-12 03:16:12
问题 The following code should output 'hello' in the console, when I mark either the text "Canvas" or the image "testimage.png" and drag and drop it on the canvas. But it doesn't work. When I add the eventListener to a textarea, it does work. But it really should be on the canvas. :/ I do not assume it is not possible. How to do it? (The html file is on my domain, and the image file is on the same domain in the same directory.) <html><head> <script type="application/javascript"> function someInits

由 一笑奈何 提交于 2019-12-12 02:59:13

iOS - UIPanGestureRecognizer : drag during animation

由 僤鯓⒐⒋嵵緔 提交于 2019-12-12 02:39:15
问题 i use UIPanGestureRecognizer to move an object along the path drawn by the user. But this object is animating and i need to interact with it during animation. Is it possible? I already try to use UIViewAnimationOptionAllowUserInteraction but no results. 回答1: Yes it is possible.

How to check for IE Drag & Drop support of any element

由 爷，独闯天下 提交于 2019-12-12 02:39:02
问题 Is there a way to check if a user agent supports drag & drop of a particular element (div, tr,...)? I've got a table with draggable table rows, which works fine in Chrome. But since Internet Explorer (up to version 9) only supports dragging of images and links (and a few others), I wanted to give it a little anchor drag handle inside the table row instead. My code looks something like this: <table> <tr draggable="true"> <td><a class="drag-handle"></a> Hello World</td> </tr> </table> JS/jQuery

why if statement with e.preventDefault ? - drag and drop javascript

由 梦想与她 提交于 2019-12-12 02:27:12
问题 I'm following this example to make a javascript html5 DnD (drag and drop): http://www.html5rocks.com/en/tutorials/dnd/basics/ To prevent the default behavior for some browsers the default event is prevented. I understand the need. But why is there also an if statement? function handleDragOver(e) { if (e.preventDefault) { e.preventDefault(); // Necessary. Allows us to drop. } // Why this if statement?, To me it seems double: if it is already there (if true), do it again...? Thanks for anyone
