Scroll Status - API

Import

Edit in sandbox 
        
            
          import ScrollStatus from 'mdb-scroll-status';
        
        
    
        
            
          @import '~mdb-scroll-status/css/scroll-status.min.css';

Usage

Via data attributes

Using the Scroll Status plugin doesn't require any additional JavaScript code - simply add data-mdb-scroll-status-init attribute to .scroll-status and use other data attributes to set all options.

Edit in sandbox 
        
            
        <div data-mdb-scroll-status-init class="scroll-status" >
          <div class="scroll-status-progress"></div>
        </div>

Via JavaScript

Edit in sandbox 
        
            
        <div id="scroll-status" >
          <div class="scroll-status-progress"></div>
        </div>
      
        
    
        
            
        const scrollStatusExample = document.getElementById('scroll-status');
        new ScrollStatus(scrollStatusExample)

Via jQuery

Note: By default, MDB does not include jQuery and you have to add it to the project on your own.

Edit in sandbox 
        
            
        <div id="scroll-status" >
          <div class="scroll-status-progress"></div>
        </div>
      
        
    
        
            
        $(document).ready(() => { 
          $('#scroll-status').scrollStatus();
        });
