<a id="editTD" data-bind="attr: { href: '/api/gridfs/files/' + $data.filename}" data-toggle="tooltip" title="Download" data-toggle="modal" data-target="#myModal"><i class="fa fa-download text-navy"></i></a>

Answer 1

您必须使用$ data.filename（）之类的括号来调用“文件名”。参见example

<a id="editTD" data-bind="attr: { href: '/api/gridfs/files/' + $data.filename() }" data-toggle="tooltip" title="Download" data-toggle="modal" data-target="#myModal"><i class="fa fa-download text-navy"></i>CLICK</a>

function ViewModel() {
  this.filename = ko.observable("aaa");
}
ko.applyBindings(new ViewModel());

<a id="editTD" data-bind="attr: { href: '/api/gridfs/files/' + $data.filename() }" data-toggle="tooltip" title="Download" data-toggle="modal" data-target="#myModal"><i class="fa fa-download text-navy"></i>CLICK</a>
