如何禁用/限制浏览器重新加载/刷新功能？

Question

Trying to do this, which is executing a default behaviour.

   window.addEventListener('beforeunload', this.beforeUnloadFunc);

   function beforeUnloadFunc(e) {
      e.preventDefault();
      e.returnValue = '';
      return null;         
   }

You may try this!

document.onkeydown = function() {
    if(event.keyCode == 116) {
            event.returnValue = false;
            event.keyCode = 0;
            return false;
           }
}
