    <select id="select">
        <option value="" selected disabled hidden>--------------</option>
        <option value="mercedes">Mercedes</option>

        Rolls Royce
    <button type="button" onclick="result('tesla')">

  1. As we here see that we today write only JavaScript codes in our example.
  2. In previous tutorials, we already many times create a full code example in which we first create an HTML form with its basic structure. We use HTML, head, title, body, and script tags inside that structure.
  3. As in the example given above we see that we create some heading tags. After that, we create a label and then select a tag. Inside the select tag, we create some options. You can see the options that we created above.
  4. Now, after that we create some buttons. The number of buttons is equal to the number of options available in the select tag. Now, our today’s task is to set the selected option value using JavaScript. So, the ways with help of which we want to set the value inside select may be different but the method remains the same. So, as we see above that a function gets called when we click on any button.
  5. And we also send a parameter to it. Now, inside the function, we just set the value of the select option based on the values of options. So, when you click on the button parameter gets passed. When the parameter matched with the value of the option the current option gets shown or activated.
