Get Input field array index in jquery

Question

I have array of input field like this;

<input type="text" name="pname[283]" value="" class="input" />
<input type="text" name="pname[678]" value="" class="input" />
<input type="text" name="pname[876]" value="" class="input" />
<input type="text" name="pname[454]" value="" class="input" />

Now i want to get the array indexes of every field inside foreach loop something like this

$('.input').each(function(e) {
   console.log('get array indexes');  eg: 283, 678, 876, 454  
 });

What have you tried so far to solve this on your own? Any attempts at all? .index() + .slice(), or a regular expression, or .split(), or ... — Andreas

You can parse the name attribute manually.

$('.input').each(function() {
   const name = $(this).prop('name');
   console.log(name.slice(name.indexOf('[') + 1, -1)); 
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="text" name="pname[283]" value="" class="input" />
<input type="text" name="pname[678]" value="" class="input" />
<input type="text" name="pname[876]" value="" class="input" />
<input type="text" name="pname[454]" value="" class="input" />
