If download a file, pjax will happen.

If download a file, pjax will happen.

  // Prefer X-PJAX-URL header if it was set, otherwise fallback to
  // using the original requested url.
  var serverUrl = xhr.getResponseHeader('X-PJAX-URL')
  obj.url = serverUrl ? stripInternalParams(parseURL(serverUrl)) : options.requestUrl

+  if (!xhr.getResponseHeader('Content-Type').match(/^text\/html/i))
+    return obj;

So I solved it in the same way as above.
