amig@ puedes hacer algo como esta pequeña validacion JS que te hice ;)
Código HTML:
Ver original<form name="ValidationForm"> Password:
<input type="password" id="password1" minlength="2"/> Confirm Password:
<input type="password" id="password2" minlength="2"/> <input type="submit" value="submit"/>
Código Javascript
:
Ver originalwindow.onload = function () {
document.getElementById("password1").onchange = validatePassword;
document.getElementById("password2").onchange = validatePassword;
}
function validatePassword(){
var pass2=document.getElementById("password2").value;
var pass1=document.getElementById("password1").value;
if(pass1!=pass2)
document.getElementById("password2").setCustomValidity("Passwords Don't Match");
else
document.getElementById("password2").setCustomValidity('');
//empty string means no validation error
}
