Get the current input value with the same class names

Question

Im trying to alert the current value that is in the input box depending on which button you click on. So if the first grid-2 button is selected it would alert 1 and if the second button with the input value of 2 was to be clicked on instead it would alert that number etc.

<div class='grid-2'>
    <input class="photo1" value="1">
    <a class='remove-photo' href='#'>Remove Now</a>
</div>

<div class='grid-2'>
    <input class="photo1" value="2">
    <a class='remove-photo' href='#'>Remove Now</a>
</div>


<div class='grid-2'>
    <input class="photo1" value="3">
    <a class='remove-photo' href='#'>Remove Now</a>
</div>


<div class='grid-2'>
    <input class="photo1" value="4">
    <a class='remove-photo' href='#'>Remove Now</a>
</div>


<script type="text/javascript">
$(document).ready(function() {
    $(".remove-photo").click(function() {
        var current_selected_photo_num = $(".photo1").val();
        alert(current_selected_photo_num);
    });
}); 
</script>

Use the .prev() function to go upwards through siblings

$(".remove-photo").click(function() { 
    var current_selected_photo_num = 
    $(this).prev('.photo1').val(); 
    alert(current_selected_photo_num); 
})
