可以使用图元上的属性。看看下面的概念，看看您是否可以使用它。

基本上，您可以隐藏所有“特色”图像生成的标记：

<img src="http://location/to/image.png" id="attachement-id-1" class="hide-it">
<a href="http://path/to/post">
    <h3 class="hover-show-attachment" hover-data="attachement-id-1">The Post Title 1</h3>
</a>
<img src="http://location/to/image.png" id="attachement-id-2" class="hide-it">
<a href="http://path/to/post">
    <h3 class="hover-show-attachment" hover-data="attachement-id-2">The Post Title 2</h3>
</a>

<script type="text/javascript">
    ( function( $ ) {
        $( \'.hover-show-attachment\' ).on( {
            mouseenter : function(){
                var attachment = $( this ).attr( \'hover-data\' );
                $( \'#\' + attachment ).show();
            },
            mouseleave : function() {
                var attachment = $( this ).attr( \'hover-data\' );
                $( \'#\' + attachment ).hide();
            }
        } );
    } )( jQuery || {} );
</script>
