downloads.pause()

The pause() function of the downloads API pauses a download.

If the request is successful, the download will be put in in a paused state; if not, runtime.lastError will be set with an appropriate error message.

The pause() call will fail if the download is not active: for example, because it has finished downloading. You can check its download state using the downloads.DownloadItem state property, and the error will be available in runtime.lastError.

Syntax

chrome.downloads.pause(
  downloadId,      // integer
  function() {...} // optional callback function
)

This API is also available as browser.downloads.pause() in a version that returns a promise.

Parameters

downloadId

An integer representing the id of the download to pause.

function() {}Optional

An optional callback function. This function will be called once the pause call has been initiated or if it fails. It will be passed no parameters.

Examples

The following snippet shows a button that when clicked invokes a downloads.download() call. Once the download starts, another button is given an event handler so that it pauses the download when clicked.

var downloadBtn = document.querySelector('.download');
var pauseBtn = document.querySelector('.pause');

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 {
      pauseBtn.onclick = function() {
        chrome.downloads.pause(downloadId, function() {
          console.log('Download paused');
        });
      }
    }
  }
}
