Implementation code:
The code copy is as follows:
<script>
function addFav(){
if(document.all){
window.external.addFavorite('http://VeVB.COM','FREE Web Directory');
}else if(window.sidebar){
window.sidebar.addPanel('FREE Web Directory', 'http://VeVB.COM','');
}
}
</script>
<a href="http://VeVB.COM" rel="sidebar" onclick="addFav();">Add to favorites</a></div>
javascript Add to favorites, you need to pay attention to a detail. If "rel=sidebar" is not added on <a>, an error will be reported: window.sidebar.addPanel is not a function.
