I want to auto fill the "Unit Price" input with the products "data-price" when a user picks a product without reloading the page. Is this possible?

```
<div class="row">
    <div class="col-sm-3">
        <p>Testers<br>
        <select id="productOne" name="productOne">
          <option data-price="1249.99" value="1">PRO Battery Tester</option>
          <option data-price="444.99" value="2">MDX335P</option>
          <option data-price="494.99" value="3">MDX645</option>
          <option data-price="694.99" value="4">MDX645P</option>
          <option data-price="694.99" value="5">MDX655</option>
          <option data-price="899.99" value="6">MDX655P</option>
          <option data-price="949.99" value="7">MDX655P Start Stop</option>
        </select></p>
        <p>Chargers<br>
        <select id="productTwo" name="productTwo">
          <option data-price="1249.99" value="1">PRO 60</option>
          <option data-price="1249.99" value="2">MXTS 70/50 EU-K</option>
          <option data-price="333.33" value="3">MXS 25EC UK</option>

          <option data-price="633.33" value="5">MXTS 40 UK</option>
          <option data-price="266.66" value="6">MXS 25 UK</option>
          <option data-price="266.66" value="7">MXT 14 UK</option>
          <option data-price="175.83" value="8">MXT 4.0 UK</option>
        </select></p>
    </div>
    <div class="col-sm-3">
