clipboard

问题 I have a canvas that i need the users to be able to paste an image onto. I would like this to be cross browser. I would like only to use html/javascript. I would also be willing to use a flash object. 回答1: This works fine in Chrome, though as of yet I haven't been able to figure out how to get it to work in Firefox. You can use this jQuery plugin to detect clipboard pastes. I'll assume you know how to draw the image once you have the data from the clipboard. # jquery.paste_image_reader.coffee

问题 I am trying to copy a standard WPF listbox selected Item (displayed) text to clipboard on CTRL+C. Is there any simple way to achieve this.

问题 I am using gVim on Ubuntu 10.10. I want to copy (yank) text to the system clipboard, so that the copied text is available in other applications. This works with "+y . But I want to have it working with y . I have tried to map y to "+y but then yy doesn't work anymore (since it produces "+y"+y ).

问题 I would like to know how to put text into the clipboard like some popular websites are able to do. I have seen sites like www.photobucket.com and www.hulu.com somehow make copying to the clipboard automatic and cross browser. How can I do the same? I saw a cross browser way to do it using flash, but it won't work with the current version? 回答1: Take a look at this: http://ajaxian.com/archives/seeding-the-clipboard-in-flash10-with-zero-clipboard 回答2: One option is Clippy, "a very simple Flash

问题 I'm working on a project that's supposed to work on both Windows and Linux (with an unofficial Mac port as well) that emulates a true colour system console. My problem is that recently there appeared a request for textfield support (yes, console-based) and it would be cool to add the possibility of copying text to clipboard and pasting from it. Is there a way of achieving this that will: be done in C (not C++), work in both Windows and in Linux (preprocessor macros are an option if there's no

问题 Not sure why this has been so difficult for me today, but for some reason I cannot seem to get it to copy the current URL to the clipboard. Overall, I'm looking for a way to do it without needing to create some hidden text elements. This is what I'm trying so far: var shareBtn = document.querySelector(".share-button"); shareBtn.addEventListener('click', function(event) { var cpLink = window.location.href; cpLink.select(); try { var successful = document.execCommand('copy'); var msg =

问题 I've been trying to copy the innerContent of a <span> to my clipboard without success: HTML <span id="pwd_spn" class="password-span"></span> JavaScript Function Call document.addEventListener('DOMContentLoaded', function () { document.getElementById('copy').addEventListener('click', copy_password); }); Function function copy_password() { var copyText = document.getElementById("pwd_spn").select(); document.execCommand("Copy"); } I've also tried: function copy_password() { var copyText =

问题 I need to come up with a solution for users to be able to paste an image on to a website, then upload that image on to the web server. I'm not sure what the right solution for this - I am pretty sure javascript is out of the question because I don't think it can handle binary clipboard data (or any clipboard data?) So, I'm not sure which way to go with this. Is this something possible with a Java applet? Or maybe a Flash SWF? Any other alternatives? 回答1: Or this free one (via another

问题 If the Clipboard contains an Excel Worksheet Range, you can access that Range's Data with the DataObject Object Can you also find the actual Source Range (ie Worksheet, Row & Column) of that Data? Alternatively, can you find the Last Copied Range, which is indicated with a Dashed Outline Border ( NOT the Selected Range)? Preferably using Excel 2003 VBA 回答1: Not directly, no - the clipboard object seems to only contain the values of the cells (though Excel obviously somehow remembers the
