If you want to use js to copy content to the clipboard, it is not difficult, but if you consider the browser compatibility problems, it becomes a bit troublesome, using jquery-zclip copy is a good choice, with flash to achieve browser compatibility. I won’t go into the details of the principle, but let’s talk about how to implement it.

For example, my HTML code is as follows:

<div class="buttonBox">
<code rel="1"><span id="id_1"> The content to be copied 1</span></code>
<code rel="2"><span id="id_2"> The content to be copied 2</span></code>
<code rel="3"><span id="id_3"> The content to be copied 3</span></code>
</div>

Js file, it will be altogether two, jquery is needless to say, and jquery - zclip. Js and ZeroClipboard SWF, these two files can be downloaded in the website, the address is as follows: http://www.steamdev.com/zclip/

Generate the js for the copy button as follows

<script type="text/javascript">
$(function(){
$('code').each(function(){
var self = $(this);
var id = self.attr('rel');
var copy = $('<span> copy </span>').appendTo(self).zclip({
'path':'/static/admin/js/ZeroClipboard.swf',//Write your own address here
'afterCopy':function(){
alert(' Gets the address of the corresponding code that has been copied to the clipboard , You can use ctrl+v paste ');
},
'copy':function(){
return $('#id_'+id).text();//Notice that if div span and so on use text(), and if input and so on use val(), this doesn't support very well
}
});
});
});

</script>

So you can time cross-browser replication, originally is not a difficult thing, when I do the test also pretty smoothly, can when I put him in the project is a problem, copy button position without flash, only words, later found that actually flash generated, but not in text location, estimated project background and I use the iframe structure, estimates that this is a bug of the plug-in, then check a lot of information, some people say, need to change the code is ok, then I changed,, indeed as expected

The code to be modified is as follows

getDOMObjectPosition: function (obj, stopObj) {
// get absolute coordinates for dom element
var info = {
left: 0,
top: 0,
width: obj.width ? obj.width : obj.offsetWidth,
height: obj.height ? obj.height : obj.offsetHeight
};

if (obj && (obj != stopObj)) {
//info.left += obj.offsetLeft; // Before the change
//info.top += obj.offsetTop; // Before the change
jpos = $(obj).position(); //The modified
info.left += jpos.left; //The modified
info.top += jpos.top; //The modified
}

return info;
}

Actually this has to do with the principle of this plug-in, it will be a transparent flash to cover the top of the button, if they do not coincide, the above problem.
