Le plug-in peut répondre à l'affichage d'invite couramment utilisé, prend en charge 12 directions, prend en charge la bordure, la couleur d'arrière-plan, la personnalisation de la couleur du texte et prend en charge le réglage fin de la position, le réglage fin du niveau, l'espacement de la largeur et d'autres ajustements de paramètres.
Jetons d'abord un coup d'œil à l'effet :

CSS :
.tip-wrap { position: absolute; display: none; } .tip-arr-a, .tip-arr-b { position: absolute; width: 0; height: 0; line-height: 0; border-style: dashed; border-color: transparent; } page: <div class="test"> <span data-tip-msg="我是测试数据<br>我是测试数据<br>我是测试数据">我是测试数据</span> </div> <script> $('.test span').tips(); </script>

Ce qui précède est un simple plug-in de boîte d'invite jQuery (Astuce). J'espère que vous pourrez l'appliquer à vos propres projets et gagner quelque chose.
