jquery - How can i add required field while creating a form?

Question

This is my code :

  <div class="form-group">
    <div class="col-md-4">
      <label class="control-label">Mobile Number:</label>
    </div>
    <div class="col-md-8">
      {!! Form::input('number', 'mobile',  null, ['type' => 'number', 'min' => 0, 'id' => 'mobile', 'class' => 'input-lg form-control TabOnEnter', 'placeholder' => 'Eg: 9876543210', 'tabindex' => 15]) !!}
    </div>
  </div>

Here i want to give this mobile number field as required, how can i add it in my code? And i am having 3 steps in the creation of form and i am having mobile number in step1, when i am clicking the next button without adding mobile number, it should display an alert message..Now it is displaying alert message of mobile field required, only after clicking submit button in last step (i.e) in step 3..

Add 'required' => true to the array:

{!! Form::input('number', 'mobile',  null, ['required' => true, 'type' => 'number'....
