I'm trying to check if ALL inputs (.productTextInput) have a value of zero.

If they are all zero then execute an alert, but only if they are ALL zero.

I have been able to check the first and all individually, but not all together.

HTML

<div class=container>

    <div class=listQuantity>

        <input type=text class=productTextInput name=AddToCart_Amount value=0>

    </div>

    <div class=listQuantity>

        <input type=text class=productTextInput name=AddToCart_Amount value=0>

    </div>

    <div class=listQuantity>

        <input type=text class=productTextInput name=AddToCart_Amount value=0>

    </div>

</div>

Script

$('.productTextInput').each(function() {

    if ($(this).val() <= 1){

        alert(Must choose at least one product);

    } else {

        // do something

    }

});

You can use filter for this:

if ($('.productTextInput').filter(function() {

        return parseInt(this.value, 10) !== 0;

    }).length === 0) {

    // They all have zero

}

else {

    // At least one has a non-zero value

}
