警告 : Removed in Firefox 65.

findAll() 方法在 HTMLIFrameElement searches for a string in a browser <iframe> 's text content; if found, the first instance of the string relative to the caret position will be highlighted.

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。

参数

范例

The following function is taken from our Browser API demo , and executes a search when a search form is submitted. See Implementing the search bar for more explanation.

searchForm.addEventListener('submit', function(e) {
  e.preventDefault();
  browser.findAll(searchBar.value, 'case-sensitive');
  searchActive = true;
  prev.disabled = false;
  next.disabled = false;
  searchBar.blur();
});
