Displaying two seperate select box values in a URL

问题

Here are both select boxes, what I need is if there are values selected from both boxes, both should be displayed in the URL, something like this e.g www.example.com#135+#140 OR www.example.com#135&140 (It doesn't matter in which sequence as long as both gets displayed that's the main aim of this)

 <select name="search_region" id="search_region" class="search_region">
        <option value="0">All Regions</option>
        <option class="level-0" value="135">HTML</option>
        <option class="level-0" value="136">PHP</option>
        <option class="level-0" value="137">CSS</option>
    </select>

    <select name="search_categories" id="search_categories" class="search_categories">
        <option value="">Select Category</option>   
        <option class="level-0" value="140">Java</option>
        <option class="level-0" value="141">Script</option>
    </select>

Below is this script I'm running to display the #search_regions value in the URL, so far it works perfect. Now to be able to add the #search_categories value to that.

<script type="text/javascript">
$(function(){
    $('#search_region').change(function () {
        var url = $(this).val();
        window.location.hash = url;
        console.log('select Changed');
    });
});
window.addEventListener('hashchange', fn, false);

window.onload = fn; // fire on pageload

function fn() {
    $('#search_region').val(window.location.hash.replace('#', ''));
    console.log("hash = " + window.location.hash);
}
 </script>

Any ideas on how to do this? it would be much appreciated

It's an add on from my previously asked question, find link below

回答1:

1.You need to apply change event of both select-box.

2.You need to add second select-box value to the window.location.hashalso.

Working snippet:-

$(function(){
   var url = '';
    $('#search_region').change(function () {
        url = $(this).val();
        window.location.hash = url;
         console.log(window.location.hash);
    });
    $('#search_categories').change(function () {
       if(url !==''){
         window.location.hash = url+"&"+$(this).val();
       }
        console.log(window.location.hash);
    });
});

window.addEventListener('hashchange', fn, false);

window.onload = fn; // fire on pageload

function fn() {
    console.log("hash = " + window.location.hash);
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="search_region" id="search_region" class="search_region">
        <option value="0">All Regions</option>
        <option class="level-0" value="135">HTML</option>
        <option class="level-0" value="136">PHP</option>
        <option class="level-0" value="137">CSS</option>
    </select>

    <select name="search_categories" id="search_categories" class="search_categories">
        <option value="">Select Category</option>   
        <option class="level-0" value="140">Java</option>
        <option class="level-0" value="141">Script</option>
    </select>
