移动端适配的js代码

移动端适配mate

放在index.html中

<meta name="viewport" content="width=device-width,height=device-height,initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">

移动端适配代码

做成一个rem.js放在assets文件夹下,然后在main.js中导入

/**
   * 设置根元素font-size
   * 当设备宽度为375(iPhone6)时，根元素font-size=16px;
   */
;(function (doc, win) {
  var docEl = win.document.documentElement;
  var resizeEvt = 'orientationchange' in window ? 'orientationchange' : 'resize';

  var refreshRem = function () {
    var clientWidth = win.innerWidth
      || doc.documentElement.clientWidth
      || doc.body.clientWidth;

    // console.log(clientWidth)
    if (!clientWidth) return;
    var fz;
    var width = clientWidth;
    fz = 16 * width / 375;  // 可以根据项目需要，自行修改
    docEl.style.fontSize = fz + 'px';  //这样每一份也是16px,即1rem=16px
  };

  if (!doc.addEventListener) return;
  win.addEventListener(resizeEvt, refreshRem, false);
  doc.addEventListener('DOMContentLoaded', refreshRem, false);
  refreshRem();

})(document, window);
