drag-and-drop

问题 I'm trying to restrict drag and drop motion to only the Y-axis so that a user can only take a view and drag it up or down--not left or right. I've got two views (ids of textView and dropZone) right now. One (textView) has a touch listener set to it and another (dropZone) has a drag listener set on it. Here's the layout xml (activity_main.xml): <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match

问题 I have a fairly good amount of knowledge with Batch. I'm trying to port a batch script over to Mac/UNIX, but my batch file has a drag-and-drop thing to it. Through countless Google searches, I have came up with nothing. They all say that you can drag-and-drop into a Terminal Window - not good for no-input-required scripts. Here is the code for Batch I have: cd %USERPROFILE% 7za x %* -o%USERPROFILE%\Desktop\Temp 7za a %1 %USERPROFILE%\Desktop\Temp\* cd %USERPROFILE%\Desktop rmdir /q /s Temp\

问题 I am looking to create a sortable (via drag and drop) grid, similar to what JQuery's Sortable grid does ( http://jqueryui.com/demos/sortable/#display-grid ). However, Sortable requires that you use only divs with identical dimensions. For my purposes, each block is allowed to be different widths and heights. The functionality I am looking for is the snap-to-grid capabilities while "shoving" the other elements out of the way. Draggable does everything except for preventing them from

问题 I have simple ol-li construction and want to add drag'n'drop to it. Additionaly I want to highlight hover item and dragover item in different colors. But it is an unusual bug in WebKit. Capture last item. Drag it to the top. Drop it to the first item. And last element capture the hover pseudoclass! Why? How can I prevent it? This is an example: http://jsfiddle.net/zFk2V/3/ var lis = document.querySelectorAll("li"), ol = document.querySelector("ol"), dragged = false, dragover = false; ol

问题 I'd like to drag an object into my Google Map (API V3) from outside the map. After some research, I found this very helpful post and I tried to adapt it to my project. The main idea is to drag a .png image on the map and when the mouse button is down, get the actual coordinates and place a marker at that lat / lng. But I noticed there is a difference between the point you drag your image and the point where your marker is placed. The difference is around 10 / 15 pixels on the sample linked

问题 I have an image loaded on the dom already, and I want to be able to drag that image into a canvas and drop it into the canvas and create a kineticjs object out of it. I don't know how to make the image draggable, and I don't know how to make the canvas react to drag and drop events that already exist on the dom. Can someone show me how to do this? Most of the tutorials show how to drag and drop from within the canvas, or the file system, I'm looking how to drag from the DOM to the canvas.

问题 I got a webpage with some html elements including a textarea and an embedded contenteditable iframe (a rte). Using this code i manage to catch the draggesture event on the main page and set the text/html-data jQuery(document).bind('draggesture', function(event){ event.originalEvent.dataTransfer.setData('text/html', 'my_data'); }); Now, when dropping in a textarea on the main page 'my_data' gets dropped. Dropping in the contenteditable iframe drops 'my_data' too. But i got three issues here

问题 I searched online and mostly found answers that it cannot be done. My case is a bit different as the application we are developing is for an in-house purposes only and can allow any security level in the browser. Its also intranet based. I also tried to see if there is a ready-made activex control but wasn't able to find one that will allow dragging directly from outlook. Any ideas? 回答1: The easiest solution I found is to just create an Add-In for Outlook to add the email to our database. 回答2
