Das Beispiel in diesem Artikel beschreibt die jQuery-HTML5-CSS3-Implementierung eines nicht aktualisierungsfähigen Formulars mit abgerundeten Ecken und Eingabeüberprüfungsfunktionscode. Teilen Sie es als Referenz mit allen. Die Details lauten wie folgt:
Hier ist ein abgerundetes Formular, ein abgerundetes Eingabefeld, keine Aktualisierungsüberprüfung, schön und schön. Dies ist eine kurze Zusammenfassung des Formulareffekts basierend auf HTML5/CSS3/jQuery. Von nun an können viele außergewöhnliche Effekte erzielt werden Sie werden sich in HTML5 verlieben und den bösen IE beschimpfen. Bisher unterstützt IE8 HTML5 nicht, was traurig ist.
Schauen wir uns die Screenshots des Laufeffekts an:

Der spezifische Code lautet wie folgt:
