lc-mouse-drag

Drag-n-scroll also on desktop devices, by LCweb

No dependencies vanilla javascript function to easily implement a nice drag-to-scroll effect using dsektop mouse.

• optionally set a mobile-device-like smooth drag animation on drag end
• optionally control only one scroll axis

Everything in less than 2KB.

Installation & Usage

• include lc-mouse-drag.min.js

• call the function targeting one/multiple page elements and eventually fill optional parameters.
  
  NB: first parameter may be a textual selector or a DOM object (yes, also jQuery objects)

<script type="text/javascript">
lc_mouseDrag('.target_elements', 
    0.3,    // (float) ending dragging animation delta. 0.3 by default, 0 to disable. 
                0.3 means the dragged distance will be increased by 30% on mouse up with a smooth animation
    
    
    false,  // (bool) whether to ignore X-axis dragging
    false   // (bool) whether to ignore Y-axis dragging
);
</script>

NB: Is essential to have a proper HTML/CSS setup in order to have it working.
For example, on desktop, you must use overflow: hidden; on the target element.

Please check the demo.html code to better understand.
The function also sets an utility class on the BODY element to know if page is being viewed on a mobile device (not needing this function).

This is the CSS code used in the demo to apply the proper CSS only on affected devices

<style>
body:not(.lc_mousedrag_is_mobile) #inner {
    overflow: hidden;
    cursor: grab;
} 
</style>
