警告 : Removed in Firefox 65.

clearMatch() 方法在 HTMLIFrameElement clears any content highlighted by findAll() or findNext() .

Invoking this method results in a mozbrowserfindchange event firing, which carries details about the search results.

注意 : Use of the Browser API requires a privileged app, and 浏览器 and/or embed-apps permissions, depending on what you want to do. See Using the Browser API 了解更多细节。

None.

范例

The following function is taken from our Browser API demo , and (amongst other things) clears the search results when the search bar is hidden, if an existing search is active. See Implementing the search bar for more explanation.

searchToggle.addEventListener('touchend',function() {
  if(search.getAttribute('class') === 'search') {
    search.setAttribute('class', 'search shifted');
  } else if(search.getAttribute('class') === 'search shifted') {
    search.setAttribute('class', 'search');
    if(searchActive) {
      browser.clearMatch();
      searchActive = false;
      prev.disabled = true;
      next.disabled = true;
      searchBar.value = '';
    }
  }
});

规范

Not part of any specification.
