vue移动端使用rem实现适配

rem.js 适配

!(function(n) {
  var e = n.document,
    t = e.documentElement,
    i = 750,
    d = i / 100,
    o = "orientationchange" in n ? "orientationchange" : "resize",
    a = function() {
      var n = t.clientWidth || 320;
      n > 750 && (n = 750);
      t.style.fontSize = n / d + "px";
    };
  e.addEventListener &&
    (n.addEventListener(o, a, !1),
    e.addEventListener("DOMContentLoaded", a, !1));
})(window);

这里是以设计图750px，1rem=100px,直接在main.js引用即可。
