Warning: Removed in Firefox 65.
The clearMatch()
method of the 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.
Note: Use of the Browser API requires a privileged app, and browser
and/or embed-apps
permissions, depending on what you want to do. See Using the Browser API for more details.
Syntax
instanceOfHTMLIframeElement.clearMatch();
Returns
Void.
Parameters
None.
Examples
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 = ''; } } });
Specification
Not part of any specification.
Browser compatibility
Supported since Firefox 47, in chrome code only. Removed completely in Firefox 65.
Unlikely ever to be supported in other browsers.
