JS基于clipBoard.js插件实现剪切、复制、粘贴

var copy = new clipBoard(document.getElementById('data'), {
beforeCopy: function() {
},
copy: function() {
return document.getElementById('data').value;
},
afterCopy: function() {
}
}); 

var cut = new clipBoard(document.getElementById('data'), {
beforeCut: function() {
},
Cut: function() {
return document.getElementById('data').value;
},
afterCut: function() {
}
});

var paste = new clipBoard(document.getElementById('data'), {
beforePaste: function() {
},
paste: function() {
return document.getElementById('data').value;
},
afterPaste: function() {
}
});
