How to wrap particular multiple divs with jQuery

Question

Just trying to work with jQuery wrapInner and I could not wrap particular multiple divs with a outer div.

$('#outer').not('#inner3')
  .wrapInner('<div id="wrapper" style="background:green;"></div>');

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id='outer'>
  <div id='inner1'>1</div>
  <div id='inner2'>2</div>
  <div id='inner3'>3</div>
</div>

How to wrap inner1 and inner2 within another div. I tried like above but this wraps whole 3 inner divs.

Output required:

<div id='outer'>
  <div id="wrapper" style="background:green;">
    <div id='inner1'>1</div>
    <div id='inner2'>2</div>
  </div>
  <div id='inner3'>3</div>
</div>

Answer 1

Try $('#outer div').not('#inner3')

$(document).ready(function () {
    $('#outer div').not('#inner3')
        .wrapInner('<div id="hey" style="background:green;"></div>');
});

$('#outer div').not('#inner3') select all div inside element with id outer but not with element with id inner3

if you want two put first two children you can use :lt()

$(document).ready(function () {
    $('#outer div:lt(2)')
        .wrapInner('<div id="hey" style="background:green;"></div>');
});

Use the .wrapAll() function:

$('document').ready(function() {
  $('#outer div').not('#inner3')
    .wrapAll('<div id="hey" style="background:green;"></div>');
});
