1. JS导出CSV中文乱码问题及兼容IE

// content 为接口传回来的值  "\ufeff"是为了解决CSV中文乱码问题
const blob = new Blob(["\ufeff" + content], {
  type: 'text/csv;charset=utf-8;'
});
// 如果是 IE 浏览器
if (window.navigator.msSaveOrOpenBlob) {
  window.navigator.msSaveOrOpenBlob(blob, 'name.csv');
} else {
  const link = document.createElement('a');
  const url = URL.createObjectURL(blob);
  link.href = url;
  link.setAttribute('download', 'name.csv');
  document.body.appendChild(link);
  link.click();
  document.body.removeChild(link);
}
