How to calculate number of days between two dates automatically. When I enter the second date, the number of days will be generated automatically in the span of the code below without using any button? I have this html code :
<div class="row mx-auto">
<div class="col">
<label for="from">fom</label>
<input type="date" required="" class="form-control" name="from">
</div>
<div class="col">
<label for="to">to</label>
<input type="date" required="" class="form-control" name="to">
</div>
<span>I want to get the difference in days between two this dates here</span>
</div>
