Please see http://www.howtocreate.co.uk/jslibs/ for details and a demo of this script
Please see http://www.howtocreate.co.uk/jslibs/termsOfUse.html for terms of use
To use:
Inbetween the tags, put:
Wherever you want to put a find in page form, put:
if( ( document.body && document.body.createTextRange ) || window.find ) {
document.write( '' );
}
Recent versions of Mozilla/Firefox will only find the first result due to a selection
problem when clicking the button. To avoid this bug, put the search form in an iframe,
and make it search the 'window.parent' page.
