Every time I click to trigger the _confirm page, I insert confirm.js how to solve this situation?

What is the desired behavior? On the second click do you want to execute the callback without loading the script?

I have the same issue. multiple visits to a page causes repeated download/adding or same file by LoadJS. Is there a way to remove the previous file before re-adding them?

You can use the .isDefined() method:

if (!loadjs.isDefined('foo')) {
  loadjs('/path/to/foo.js', 'foo', function() { /* foo.js loaded */})
}
