Currently, if you use JavaScript to write code that is copied to the Clipboard, it is generally not compatible with browsers. So the way to use flash, simulation of a layer, and then to copy, you can do all the browser application Oh ~
Need to download a SWF file, and a JS file. Put the two files, and the HTM together.
Must be placed on the server side to use OH.
