Make a dropdown selection according to the selected div (with jQuery)

I have these divs (links) that can be clicked on.

I want to change a dropdown selection accordingly.

So if it’s clicked on select2, it would change the dropdown value to 666

If select3, it would change to 667

and so on.

I can’t modify dropdown values, however the target id’s CAN be exact as dropdown values, if that will make things easier to code.

I know there are some mistakes in my jQuery script.

Any help would be appreciated.

<script>
const select = $('#sel2');

// Initialize at position 1
selectElement('665');


select.change(function() {
  selectElement($(this).val());
})

function selectElement(id) {
  $('#' + target).addClass("selected");
  others.removeClass("selected");

}
</script>

<a href="#1"><div style="display: inline-block; margin-bottom: 0.4em;" class="showSingle greenactive" target="01">select1</div></a>
<a href="#2"><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="02">select2</div></a>
<a href="#3"><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="03">select3</div></a>
<a href="#4"><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="04">select4</div></a>
<a href="#5"><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="05">select5</div></a>
<a href="#6"><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="06">select6</div></a>
<a href="#7"><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="07">select7</div></a>
<a href="#8"><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="08">select8</div></a>
<a href="#9"><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="09">select9</div></a>
<a href="#10"><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="10">select10</div></a>
<a href="#11"><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="11">select11</div></a>

Answer

well, your Jquery code is a bit wrong, you need to add the select values to the <a> (maybe in data attributes), then set a listener on <a> fields that will trigger a function to change the select value
the full code will be like this :

$(".href").click(function(){
  $(".select_a").val($(this).attr('data-value')).change();

});

<a href="#1" class="href" data-value = '665'><div style="display: inline-block; margin-bottom: 0.4em;" class="showSingle greenactive" target="01">select1</div></a>
<a href="#2" class="href" data-value= '666'><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="02">select2</div></a>
<a href="#3" class="href" data-value = '667'><div style="display: inline-block; margin-bottom: 0.4em" class="showSingle" target="03">select3</div></a>
