htc QQ 里面打开:

这是我的适配代码:

(function(win) {
    var doc = win.document,
      html = doc.documentElement,
      baseWidth = 720,
      rem = baseWidth / 100,
      resizeEvt = 'orientationchange' in win ? 'orientationchange' : 'resize',
      recalc = function() {
        var clientWidth = html.clientWidth || 320;
        // if( clientWidth > 750 ){ clientWidth = 750 };
        html.style.fontSize = clientWidth / rem + 'px';
      };
    if (!doc.addEventListener) return;
    win.addEventListener(resizeEvt, recalc, false);
    doc.addEventListener('DOMContentLoaded', function() {
      setTimeout(recalc)
    }, false);
  })(window);
