w3c clipboard api is been implemented by all the browser http://caniuse.com/#feat=clipboard

回答2:

The clipboard manipulation is not cross-browser. For cross-browser solution you need flash.

Look at this library https://github.com/jonrohan/ZeroClipboard

You can use ZeroClipboard like this:

<button id="my-button" data-clipboard-text="Copy me!">Copy to Clipboard</button>
<script>
    var clip = new ZeroClipboard(document.getElementById('my-button'));
</script>

When you click on the button the text Copy me! will be put into the clipboard.

For further instructions check the library's API https://github.com/jonrohan/ZeroClipboard/blob/master/docs/instructions.md

I think the window.clipboardData is IE only. Accessing the clipboard is a security concern, and thus cannot be done easily in FF or Chrome.

Please see this thread: How do I copy to the clipboard in JavaScript?

回答4:

See the documentation for clipboardData, specifically the section that reads:

There are no standards that apply here.

You are using proprietary Microsoft gubbins, so it shouldn't be expected to work on other browsers.

See this question for cross-browser techniques to access the clipboard.

There is a draft of a standard for accessing the clipboard but I'm not aware of any implementations of it in the wild (and canIuse doesn't know of any either).

I had this same problem with Chrome and other browsers recently. However, recently, I found this code works in a contenteditable field in certain browsers:

clipboard = e.originalEvent.clipboardData;
clipboard.setData('text/plain', plainData);
clipboard.setData('text/html', htmlData);

NOTE: e in this case is the copy and/or cut event. This event fires and is retrievable in an onCopy() or onCut() action.

This code is confirmed to work in the latest versions of the following browsers:

• Chrome (PCs/Macs and Android)
• Android 4.4+ WebView (as long as you update from the Play Store) -> good news for Android Devs
• Firefox
• Safari (Mac only)

Internet Explorer seems to work with window.clipboardData.setData instead, but keep in mind that the IE clipboard will only accept 'text' and 'url' data.

While the following browsers can access the system clipboard object, these are unable to set data into the clipboard using clipboard.setData:

• MS Edge
  • gives an UntrustedDragDrop object into the clipboard instead...
  • also, setData returns true... when it doesn't work. setData returns undefined in all other browsers
• Android WebView -> below 4.4
• iOS Safari and WebView - yay iOS!
