Non-standard
This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.
This API is available on Firefox OS for privileged or certified applications only.
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 = '';
}
}
});
