Javascript/FLASH to copy code to the clipboard (compatible with all browsers) _ javascript skills

Javascript is used to write the code copied to the clipboard, which is generally incompatible with browsers. So we can use flash to simulate a layer and then copy it to make it suitable for all browsers. The specific implementation is as follows. If you are interested, refer to the following, if javascript is used to write the code copied to the clipboard, it is generally not compatible with the browser. So we can use flash to simulate a layer and then copy it to make it suitable for all browsers ~
