Let's suppose we have a dropdown toggle:

<label for="num-of-records">Rows per Page: </label>
<select name="num-of-records" id="num-of-records">
  <option value="" selected>default</option>
  <option value="25">25</option>
  <option value="50">50</option>
</select>

And we also have a liquid code:

{% include 'page' key: 'table' %}

For key, I have provide some options table,table25, and table50 for each dropdown options value.

I am new to liquid, but I want to create a jquery which select the key value based on the dropdown.

<script>
$(this).append("{% include 'page' key: 'table"+ $.("#num-of-records").val()+"' %}"
</script>

So let's say I choose option 25, so it will (maybe reopen the page) append liquid script of:

{% include 'page' key: 'table25' %}
