Examples

The following snippet shows two buttons, "download" and "show". The first button when clicked initiates a download via downloads.download(). Once the download has started, the second button can be pressed to show the file in the file manager:

var downloadBtn = document.querySelector('.download');
var showBtn = document.querySelector('.show');

downloadBtn.onclick = function() {
  chrome.downloads.download({ url : 'https://www.example.com/myBigVideo.mp4'},
  callback);

  function callback(downloadId) {
    if(chrome.runtime.lastError) {
      console.log(chrome.runtime.lastError);
    } else {
      showBtn.onclick = function() {
        chrome.downloads.show(downloadId, function(success) {
          if(success) {
            console.log('File shown in explorer');
          }
        });
      }
    }
  }
