IE不支持html5 file api中readAsBinaryString，貌似还是ie10可以，ieEdge可以ie11不行，真是一个神奇的存在
然后找了个方法（轮子是造不出了只能搬砖了），大神重写了readAsBinaryString

FileReader.prototype.readAsBinaryString = function (fileData) {
var binary = "";
var pt = this;
var reader = new FileReader();
reader.onload = function (e) {
    var bytes = new Uint8Array(reader.result);
    var length = bytes.byteLength;
    for (var i = 0; i < length; i++) {
        binary += String.fromCharCode(bytes[i]);
    }
    pt.content = binary;
    pt.onload(pt); //页面内data取pt.content文件内容
  }
  reader.readAsArrayBuffer(fileData);
}

下面是页面读取excel

doUpload() {
  if(!$("#file").get(0).files[0]) {
      return;
  }
  var file = $("#file").get(0).files[0];
  var reader = new FileReader();
  var strArr = [];
  var wb;
  var rABS = false;
  let that = this;
  reader.onload = function(data) {
  var data = data.content;
  if(rABS) {
    wb = XLSX.read(btoa(this.fixdata(data)), { //手动转化
        type: 'base64'
    });
  } else {
    wb = XLSX.read(data, {
    type: 'binary'
    });
  }
  //wb.SheetNames[0]是获取Sheets中第一个Sheet的名字
  //wb.Sheets[Sheet名]获取第一个Sheet的数据
  var tempArr = XLSX.utils.sheet_to_json(wb.Sheets[wb.SheetNames[0]]);
  for(var i = 0; i < tempArr.length; i++) {
      var tt = tempArr[i];
      var ss = {};   
      ss.filename = tt['文件名称'];
      ss.filenum = tt['张数'];
      ss.remark = tt['备注'];
      ss.editable = false;
      strArr.push(ss);
      that.form.qdmxVOS.push(ss);
  }
  that.dialogVisible = false;
  that.page = 'view';
  };
  if(rABS) {
      reader.readAsArrayBuffer(file);
  } else {
      reader.readAsBinaryString(file);
  }

}
