I need to alert if option is selected in other select option value. i disabled the option if selected but it can not insert into database because of disabled attribute. so i only want to alert.

This change function disabled the option if other select option is selected. When I change to alert it not working. How to only alert if selected in other select option.
$('.input_slip_no').on('change', function() {
var selected_options = $('.input_slip_no').map(function(){
return this.value
}).get();
$('.input_slip_no option').each(function(index) {
$(this).prop('disabled', $.inArray($(this).val(), selected_options) != -1);
});
});

Here you go with the jQuery selector as below,
Note: I have added empty element as initial selected value since the same value has been selected in your sample above.
$('.input_slip_no').change(function(){
var selected = $(this).val();
if(selected) {
var otherSelected = $('.input_slip_no').not($(this)).find('option[value="' + selected + '"]:selected');
if(otherSelected.length > 0) {
alert('Option is already selected');
$(this).val('');
}
}
});

$('#category').change(function() {
var $cat = $(this).find('option:selected');
var $subCat = $('#subcategory').find('.' + $cat.attr('class'));
$('#subcategory').find('optgroup').not("'"+ '.' + $cat.attr('class') + "'").hide(); // hide other optgroup
$subCat.show();
$subCat.find('option').first().attr('selected', 'selected');
});
</script>

Here is an idea on where I updated slightly the second select to make the select mode type outside the optgroup. You will see that you won't be able to click on send until you select both values.
You can refer to this link to understand my changes:

var $subCat = $('#subcategory').find('.' + $cat.attr('class'));
$('#subcategory').find('optgroup').not("." + $cat.attr('class')).hide();
$subCat.show();
$('#subcategory option').removeAttr('selected');
$('#subcategory > option').attr('selected', 'selected');
//adding this will make it required
$('#subcategory').attr('required','required')

x[i++].style.display = 'block';
}
}
</script>

you can achieve this by hiding all select but the first one on page load and displaying them one by one after selecting the previous select.
<select required id='month' class='selectOption hide' onchange='select(this)'>
<select required id='day' class='selectOption hide' onchange='select(this)'>
plunker : http://plnkr.co/edit/oKwq0q4IB5poKuUOa6oG?p=preview
Define your function like this.
function select(par) {
if (par.selectedIndex !== 0) {
par.nextElementSibling.className = "selectOption";
}
}

Set Hidden Value Depending on Selection of two Dropdowns

I am trying to set a hidden value depending on the values set for two different dropdown boxes.
Here is what I have so far, it is not working, I expect it to set the value of #bundle_option[5] to 4 when the dropdown #bundle-option-5-color is set to Black and #bundle-option-5-size is set to Child.
<script type='text/javascript'>
$j(document).ready(function() {
$j('#bundle-option-5-color').change(function() {
if ($j(this).find('option:selected').text() == 'Black' &&
$j('#bundle-option-5-size').find('option:selected').text() == 'Child')
{
$j('#bundle_option\\[5\\]').val('4');
}
});
});
</script>
HTML:
<select id="bundle-option-5-color" name="bundle_option[5]" bundle-option-select="" required-entry="" required="">
<option value="">Choose a selection...</option>
<option value="Black">Black</option>
<option value="Blue">Blue</option>
<option value="Pink">Pink</option>
<option value="Purple">Purple</option>
<option value="Red">Red</option>
<option value="Teal">Teal</option>
<option value="White">White</option>
</select>
<select id="bundle-option-5-size" name="bundle_option[5]" bundle-option-select="" required-entry="" required="">

<option value="Adult XX-Large">Adult XX-Large</option>
</select>
<input id="bundle_option[5]" type="hidden" value="" name="bundle_option[5]">

Bind your function to the both change events:
$(document).ready(function() {
var fn = function() {
if ($('#bundle-option-5-color').find('option:selected').text() == 'Black' &&
$('#bundle-option-5-size').find('option:selected').text() == 'Child')
{
$('#bundle_option\\[5\\]').val('4');
}
};
$('#bundle-option-5-color').change(fn);
$('#bundle-option-5-size').change(fn);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="bundle-option-5-color" name="bundle_option[5]" bundle-option-select="" required-entry="" required="">
<option value="">Choose a selection...</option>
<option value="Black">Black</option>
<option value="Blue">Blue</option>
<option value="Pink">Pink</option>
<option value="Purple">Purple</option>
<option value="Red">Red</option>
<option value="Teal">Teal</option>
<option value="White">White</option>
</select>
<select id="bundle-option-5-size" name="bundle_option[5]" bundle-option-select="" required-entry="" required="">
<option value="">Choose a selection...</option>
<option value="Child">Child</option>
<option value="Youth">Youth</option>
<option value="Adult Small">Adult Small</option>
<option value="Adult Medium">Adult Medium</option>
<option value="Adult Large">Adult Large</option>
<option value="Adult X-Large">Adult X-Large</option>
<option value="Adult XX-Large">Adult XX-Large</option>
</select>
<input id="bundle_option[5]" type="text" value="" name="bundle_option[5]">

As mentioned in the comments you need to trigger your function for both option box change events. You can do that with this wildcard selector $('[id^=bundle-option-5]').change(function() {}).
Please find your code below and here at jsFiddle.
$(document).ready(function() {
$('[id^=bundle-option-5]').change(function() {
//console.log(this);
// size or color changed
if ($('#bundle-option-5-color').find('option:selected').text() == 'Black' &&
$('#bundle-option-5-size').find('option:selected').text() == 'Child')
{
$('#bundle_option\\[5\\]').val('4');
alert('black and child chosen!');
}
});
});

Get or Set Value(s) on A Multi-select Form Field

When you have a multi-select form field such as the following, how do you get, and set the selected option values?
<select class="items" multiple="multiple" size="5">
<option value="apple">apple</option>
<option value="ant">ant</option>
<option value="ape">ape</option>
<option value="age">age</option>
<option value="boy">boy</option>
<option value="banana">banana</option>
<option value="carrot">carrot</option>
</select>
Getting the value(s)
var items = [];
$('select.items option:selected').each(function() {
items.push( this.value );
});
Is this the only way to get the array of values or is there a sleeker way?
Setting the value(s)
var items = ['apple', 'ape', 'carrot'];
$.each(items, function() {
$('select.items option[value="' + this + '"]').prop('selected', true);
});
Is there a sleeker way to do this?

It's quite straight-forward to get the selected values array; use the jQuery .val() method.
var items = $('select.items').val();
//sample result: ["apple","ape","boy","daisy","eagle"]
Please note that JavaScripts value property, which works well for other form fields, returns just the first selected value
function out( v ) {
$('pre.out').text( JSON.stringify( v ) );
}
$('select.items').on('change', function() {
out( $(this).val() );
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select class="items" multiple="multiple" size="5">
<option value="apple">apple</option>
<option value="ant">ant</option>

To set the selected values also requires no looping. Use the same jQuery .val() method.
$('select.items').val( ['apple','ape','boy','age','eagle'] );
$('button.set').on('click', function() {
$('select.items').val( ['apple','ape','boy','age','eagle'] );
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select class="items" multiple="multiple" size="5">
<option value="apple">apple</option>
<option value="ant">ant</option>
