This is example of how you can insert result from js function back to html
function myFunction() {
const e = document.getElementById("jobSel");
job = e.options[e.selectedIndex].value;
const node = document.createElement("p");
node.innerText = job;
document.getElementById("test").appendChild(node);
};<div class="form-group">
<label for="exampleInputName1">Fuel Type</label>
<select name="f_type" id="jobSel" class="form-control" onchange="myFunction()">
<option value="">No Selected</option>
<option value="1">Petrol</option>
<option value="2">Diesel</option>
<option value="3">Kerosine</option>
<option value="4">Others</option>
</select>
</div>
<div id="test"></div>
