Manipulate two selects on page load with jQuery

jQueryWeb DevelopmentFront End Technology

Let’s say the following is our first select −

<select name="all_name" id="all_present_name">
   <option value="John">John</option>
   <option value="David">David</option>
   <option value="Bob">Bob</option>
   <option value="Mike">Mike</option>
   <option value="Sam">Sam</option>
   <option value="Carol">Carol</option>
</select>

Following is our second select −

<select name="common_name" id="remaining_name">
   <option value="David">David</option>
   <option value="Mike">Mike</option>
   <option value="Carol">Carol</option>
</select>

We need to remove the options in the first select, which are similar to options in the second select. For this, use val(). Following is the complete code −
