IOS下双击背景, touchmove, 阻止页面背景scroll.

ios prevent dblclick(tap) page scroll
html add:("minimal-ui" is very important)

<meta name="viewport" content="width=device-width,initial-scale=1.0,maximum-scale=1.0,usker-scalable=no,minimal-ui">

eg: 以lightbox_me.js举例说明

var opt = {
  centered: true,
  zIndex: 99999,
  overlaySpeed: 1,
  lightboxSpeed: 1,
  preventScroll: true,
  showOverlay: true,
  onClose: function(){
    $('.js_lb_overlay').remove();
    $('section').unbind('touchmove');//$('section') is page's element
  },
  onLoad: function(){
    $('section').on('touchmove', function (e) {
      e.preventDefault();
    });
    $('.js_lb_overlay').on('touchstart', function (e) {// touchstart!!!
      e.preventDefault();
    });
  },
  closeSelector:'.js_close',
  overlayCSS:{background: '#000000', opacity:0.7}
};
