Set dropdown to default value using javascript
<p>I have a dropdown on my html page, when it is first loaded, it is set to a default value. But when a user changes the value, I'm checking the selected value against another text field. If the condition does not satisfy, I want to show an alert to the user and reset the dropdown. </p>

<p>I'm able to show the alert with my condition, but how do I reset the dropdown after showing an alert to the user.</p>
