Question

if(!$.trim($('.xlarge').value).length) {
    return false;
}

And the HTML is:

<input class="xlarge" name="name">

I checked on my console if the syntax is right, it is right, but even if the value is not empty it still doesn’t submit the form. What’s wrong?

Answer 1

No need to check length just use :

if(!$.trim($('.xlarge').val())) {
     return false;
}

val() returns the value of the input – docs for val()
