HTML5 Formulario-"campo requerido" no funciona en IOS

[rodrypaladin]

Encontré est solución en JQuery, no la he probado pero supuestamente es para ello.

Código Javascript:

$('form').submit(function(){
    var required = $('[required="true"]'); // change to [required] if not using true option as part of the attribute as it is not really needed.
    var error = false;
 
    for(var i = 0; i <= (required.length - 1);i++)
    {
        if(required[i].value == '') // tests that each required value does not equal blank, you could put in more stringent checks here if you wish.
        {
            required[i].style.backgroundColor = 'rgb(255,155,155)';
            error = true; // if any inputs fail validation then the error variable will be set to true;     
        }
    }
 
    if(error) // if error is true;
    {
        return false; // stop the form from being submitted.
    }
});
