title: iScroll page currently scrolling to detection
body: <p>I use the following <em>iScroll 5</em> code (generally, not so important: <strong>just a common scrolling page-by-page</strong>):</p>
  
  <pre><code>        var myScroll = new IScroll('.scroller', {
              mouseWheel: true,
              scrollbars: true,
              keyBindings: {
                  // doesn't matter
              },
              preventDefault: false,
              fadeScrollbars: true,
              snap: 'section', // &lt;-- that's the key
              wheelAction: 'scroll',
          });
  
          myScroll.on('beforeScrollStart', function (e) {
              myScroll.preventDisabling = true;
          });
  
          myScroll.on('scrollMove', function (e) {
  
          });
          myScroll.on('scrollStart', function (e) {
  
              // !!! I need the detection somewhere here !!!
  
              if (!myScroll.preventDisabling) {
                  myScroll.disable();
  
                  disabledWasCalledInMeanwhile = true;
              }
  
              myScroll.preventDisabling = false;
          });
  
          var disabledWasCalledInMeanwhile = false;
          // that's just to prevent jumping to another page before scrolling is finished
          myScroll.on('scrollEnd', function (e) {
  
              disabledWasCalledInMeanwhile = false;
              window.setTimeout(function () {
                  if (!disabledWasCalledInMeanwhile)
                      myScroll.enable();
  
              }, 250);
  
  
              $('.labels&gt;*').toggleClass('active', false)
                  .eq(this.currentPage.pageY).toggleClass('active', true);
  
          });
          myScroll.on('scrollCancel', function (e) {
  
              myScroll.enable();
          });
  </code></pre>
  
  <p>So, is there any chance <strong>to detect</strong> in <code>beforeScrollStart</code> or <code>scrollStart</code> <strong>the page</strong> I am going <strong>to scroll to</strong>? That's important to know for triggering that page items animation. Thanks!</p>
