Encontré est solución en JQuery, no la he probado pero supuestamente es para ello.
Código Javascript
:
Ver original$('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.
}
});
