2. 屏幕的缩放

const initScale = function () {
  let winW = $(window).width() < 1400 ? 1400 : $(window).width()
  let radio = winW / 1900
  radio = radio > 1 ? 1 : radio
  $('#loadingpart, .wrap').css({
    '-webkit-transform': `scale(${radio}, ${radio})`,
    '-moz-transform': `scale(${radio}, ${radio})`,
    '-o-transform': `scale(${radio}, ${radio})`,
    '-ms-transform': `scale(${radio}, ${radio})`,
    'transform': `scale(${radio}, ${radio})`,
    '-webkit-transform-origin': 'top left',
    'transform-origin': 'top left'
  })

  $('#footer-wrap').height(radio*1560);
}
