Question: How will i set selected value=Booking.

```js
$('#status').val("Booking");
```

```html
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="status" class="form-control">
   <option value="" id="status">New</option>
    <option value="">Follow</option>
    <option value="">DND</option>
   <option value="">Dead</option>
</select>
```

Answer: 
try to follow the below example. there is no booking option in your select add it like below code

```
$('#mySelect')
         .append($("<option></option>")
                    .attr("value",key)
                    .text("Booking"));

```
Try this:

```
<select id="status" class="form-control">
   <option value="">New</option>
    <option value="">Follow</option>
    <option value="">DND</option>
   <option value="">Dead</option>
  <option value="Booking">Booking</option>
</select>

```

and the script should be:

```
$(document).ready(function() {
  $('#status').val("Booking");
});

```

Also I have changed the name attribut to id since you are referring it using the '#' :)
