$.each() index start number in jQuery

Question

How do I start jQuery $.each() index from 1 instead of 0?

I am using .each function to populate select box. So here I want to populate options in the se

Answer 1

This is what I did:

var start = index + 1;

This just adds 1 to the current index.. then use that new variable instead of 'index'.

Answer 2

var data = [42, 1337];
$.each(data, function(i) {
  i++;
  console.log(i);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Answer 3

$.each

So try

$.each(obj, function(i, elem) {
    if (i === 0) return;
    // do stuff
});

Alternatively rewrite your code so its so indexes and data start at 0. JavaScript is interally 0 based rather then 1 based like Matlab and some other languages.

Answer 4

Seeing the clarification points in the comments below, jQuery.each or some variation thereof isn't the right tool at all. Use a for loop, and add 1 to the index to output the value of the <option>.

Use .prepend to insert an option as the first child of a select:

for (var i = 0; i < 10; i++) {
    $('select').prepend('<option>' + (i + 1) + '</option>');
}

Answer 5

You can start at any given starting value by simply adding that number to the current loop-set index value.

$.each(( index ) => {

    index += 1 //or any other starting value

    // your code
});

Answer 6

You can't. Why not just declare another variable at the first line of the function var myIndex = index + 1;?
