title: How to check zoom level is below 100% (ctrl and - ) in each browser?
body: <p>In the browser by default the user can either use ctrl +/-  or ctrl scroll to zoom in or zoom out the page. I would like to know is there any way to check the zoom level is below 100% and not doing something </p>
  
  <p>eg. My code</p>
  
  <pre><code>$(window).resize(function() {
      if ($(window).height() &gt; 500 &amp;&amp; $(window).width() &gt; 600 &amp;&amp; $('.royalSlider:visible').length &lt; 1 &amp;&amp; !isiPhone()){
  
          //Not allow the page size &lt; 0
          Book.zoom_auto();
          Book.book_position();
          Book.dragdrop_init();   
  
          if ($(".viewportBinder").length){                   
                  $("#view").css('height',$(window).height());
                  $("#view").css('width',$(window).width());  
                  content = element.viewport('update');     
          }
      }
  calculate_zoom_factor();
  });
  </code></pre>
