drag-and-drop

问题 So I have a "File" object (retrieved by handling file drag and drop from desktop). I can send the files to the server with ajax, and then throw them back for javascript to handle them. But is it possible to read the contents of it without doing all this? Here, play around with this fiddle. Drag any file to the box and use the variable file . I've already tried all of the methods of this object...no luck. Can you get the contents of the file you just dragged into the browser? PS: I would send

问题 I have successfully managed to upload a file to a Node server using the multer module by selecting the file using the input file dialog and then by submitting the form, but now I would need, instead of submitting the form, to create a FormData object, and send the file using XMLHttpRequest , but it isn't working, the file is always undefined at the server-side (router). The function that does the AJAX request is: function uploadFile(fileToUpload, url) { var form_data = new FormData(); form

问题 (I've searched and browsed XSLT questions, as well as looked at Altova's product, though not yet Stylus's product.) I do not want to hear again that XSLT is complicated and difficult to hand-code. That's how HTML was when it was first popularized. (I know, apples and oranges comparison because XSLT is a processing language and HTML is just a display and meta-tagging language.) But now very few people hand-craft HTML. They just use WYSIWIG editors and get on with their (programming) lives. And

问题 We have a sortable list using JQuery UI Sortable that we are trying to automate using Selenium. It looks like the dragAndDrop function should work, but when we call it, the UI does not change. However if we look at the DOM with firebug, we see that the order of the list elements DID change. It seems it's just the UI that does not refresh. Any idea how to get it working? 回答1: Try dragAndDropToObject. I was just able to move things around using Se-IDE (though I suspect Se-RC would work as well)

问题 A JComponent of mine is firing a mouseDragged event too vigorously. When the user is trying to click, it interprets is as a drag even if the mouse has only moved 1 pixel. How would I add a rule for a particular component that amounted to: Do not consider it a drag event unless the mouse has moved 10 pixels from the point at which is was pressed down. Note: I know it's not a system setting in my OS, since only events on that component suffer from this over sensitivity. Thank you. 回答1: I've had

问题 I am fairly new to jQuery and am stuck trying to get a dragged image elements id to append to the drop target instead of the image element itself or the drop targets id. I am using the html5 native DnD. And so far I can get the element itself to append by sending through its id with the datatransfer method in the drag function and the getdata function in the drop. Whenever I try to call that id from the drop however it gets the drop target id instead of the dragged elements. Any help would be
