Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
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.
Example
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 = '';
}
}
});
