simple with required attribute

<input type="text" required="true">
<input type="file"  required="true">
<button type="submit">validate</button>
</form>

Or with Javascript validation

$('button').click(function(){
 var a =$(".validate").map(function(){
  return $(this).val().trim() ? true : false
}).get()
if(a.includes(true)){
console.log('pass')
}
else{
console.log('select any one')
}
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" class="validate">
<input type="file" class="validate">
<button>validate</button>
