使用clipboard.js如何在创建新对象之前销毁它的所有对象？

Question

Using clipboard something like this in my controller

function myController() {
    new Clipboard('.btn', {
        text: function(trigger) { return 'some dynamic text'; }
    }
}

Now the issue is everytime the controller is loaded, it creates a new object of Clipboard, is there any way I can destroy all its objects before creating new? here is the link to library: https://zenorocha.github.io/clipboard.js/

Just save the instance of the clipboard and erase the previous one:

var previousClipboard = null;

function myController() {
    if(previousClipboard != null){
        previousClipboard.destroy();
    }
    previousClipboard = new Clipboard('.btn', {
        text: function(trigger) { return 'some dynamic text'; }
    }
}
