vuejs用window.open打开base64图片

// 预览
export function winOpenFile(fileName, content) {
  if (imgReg(fileName)) {
    // 验证是否为图片
    const img = new Image();
    img.src = content; //base64图片链接
    const newWin = window.open("", "_blank");
    newWin.document.write(img.outerHTML);
    newWin.document.title = fileName
    newWin.document.close();
  } else {
    window.open(content, "_blank");
  }
}
