使用 Sweet Alert 进行输入验证的 CSS 样式

  • 772

此代码对使用CSS的输入产生影响，使其看起来很漂亮，并且正常使用所需的验证，但是当我使用Javascript和Sweet Alert使其工作时，我需要从输入中删除所需的，但我失去了效果，它不会降低标签。

该页面工作正常，但是有没有办法通过删除required来使其工作而不会失去标签的效果？

$("#enviar" ).submit(function( event ) {
var parametros = $(this).serialize();    
var data = new FormData(this);
if($("#nombre").val() == "") { 
swal({
        icon: 'info',
        text: 'Ingrese nombres',
        closeModal: false
        }).then(function() {
        swal.close();
        $('#nombre').focus();
}); 
return false;
}
});

    在 CSS remove 中, .input-data input:valid ~ label，因为没有required该字段，它会自动验证并采用该规则。

    现在我们只需要一个新类isValid和一个函数来解析每次更改字段的值以添加或删除类：

    $("#enviar" ).submit(function( event ) {
var parametros = $(this).serialize();    
var data = new FormData(this);
if($("#nombre").val() == "") { 
swal({
        icon: 'info',
        text: 'Ingrese nombres',
        closeModal: false
        }).then(function() {
        swal.close();
        $('#nombre').focus();
}); 
return false;
}
});

// Asignar evento para ver los cambios en el campo
$('#nombre').on('change', function() {
   // Cambia la comparación para realizar una validación adecuada
   if($(this).val() == '') {
       // No es válido, quitar clase
       $(this).removeClass('isValid');
   } else {
       // Es válido, agregar clase para mover etiqueta
       $(this).addClass('isValid');
   }
});
