I hope this helps you . You must use quotes when an attribute value contains special characters (like [ & ])
code :
$("input[id=steckdose]").on("change", function(){
    if($(this).is(":not(:checked)"))
        $(function() {
            $('[name="ItemOrderParams[0][g19]"]').val( '3' );
    })
});
$("input[id=steckdose]").on("change", function(){
    if($(this).is(":checked"))
        $(function() {
            $('[name="ItemOrderParams[0][g19]"]').val( '2' );
    })
});

this one helps. You just need some quote adjustment and your selector is off, like this:
code :
$('select[name="content_fonts"]').click(function(){
   $('.leftpanel').css('font-family','"Times New Roman", Times, serif');
});
$('select[name="content_fonts"]').change(function(){
    $('.leftpanel').css('font-family', $(this).find(":selected").text());
});

Hope this helps , Change the ID's of the parent boxes to haev a capitalized M i.e:
code :
<input type="checkbox" id="chkMain" />
<input type="checkbox" id="chkMain1" />
<input type="checkbox" id="chkMain2" /> 
$(function(){  
        $("input[id^=chkMain]").click ( function() {  
            if( !$(this).is ( ":checked" ) ){       
                $(".child").attr ( "disabled" , true );     
            }      
            else{       
                $(".child").removeAttr ( "disabled" );     
            }   
        }); 
    });

it fixes the issue The "correct" way to set checkboxes and radio buttons as of jQuery 1.6 is $('#myCheckBox').prop('checked',true) -- or omit the second argument to get the value instead.
In older versions of jQuery, you'd set it like so: $('#myCheckBox').attr('checked','checked')

it should still fix some issue You can use .index(), it searches for a given element from among the matched elements.
code :
$('#next').on('click', function () {
    var selected = $('select option:selected');
    var index = $('select option').index(selected);
    var value = $('select option').eq(index + 1).val();
    $('select').val(value);
});

$('#prev').on('click', function () {
    var selected = $('select option:selected');
    var index = $('select option').index(selected);
    var value = $('select option').eq(index - 1).val();
    $('select').val(value);
});

I hope this helps you . You only give val() the value of the checkbox which was selected last. To make this work as you require you need to build an array of all selected checkboxes and provide that to val() instead.
To achieve this you can use filter() to get the selected checkboxes, then map() to build the array:
code :
input.val(checkboxes.filter(':checked').map((i, el) => el.value));
$(document).ready(function() {
  var $input = $('#entry-select');
  var $checkboxes = $('.entrycheckbox');

  $checkboxes.click(function() {
    $input.val($checkboxes.filter(':checked').map((i, el) => el.value));
  })
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" class="entrycheckbox" value="1">
<input type="checkbox" class="entrycheckbox" value="2">
<input type="checkbox" class="entrycheckbox" value="3">
<form action="">
  <select name="entries" id="entry-select" multiple>
    <option value="1">Option1</option>
    <option value="2">Option2</option>
    <option value="3">Option3</option>
  </select>
</form>
