J'ai écrit un plug-in de validation de formulaire qui prend en charge la validation ajax et est très simple à utiliser.
Il y a une balise span sous chaque élément du formulaire qui doit être vérifiée. La classe de cette balise a une valeur valide, ce qui signifie qu'elle doit être vérifiée. S'il y a une valeur nullable, cela signifie qu'elle peut être vide, ce qui signifie des règles de validation. , msg signifie message d'erreur ; to signifie qu'il doit être vérifié. La valeur du nom de l'élément à vérifier. Si l'élément est unique, to ne peut pas être écrit. Ce plug-in parcourra chaque balise span valide pour trouver l'élément devant elle qui doit être vérifié et le vérifiera conformément à la règle. Si la vérification échoue, la bordure d'affichage sera rouge et un message d'erreur sera affiché. affiché lorsque la souris est placée sur l'élément.
Calendrier de vérification : 1. Appelez explicitement la méthode de vérification lorsque vous cliquez sur le bouton de soumission 2. Vérifiez quand l'élément déclenche le flou ;
Code du plug-in :
CSS :
.failvalid { border: solid 2px red !important; }
JS :
