如何使用javascript获取pdf阅读器的名称

function getPDFReaderName() {
  var plugins = navigator.plugins;
  var pdfReaderName = "";

  for (var i = 0; i < plugins.length; i++) {
    var plugin = plugins[i];
    if (plugin.name.indexOf("Adobe Acrobat") !== -1) {
      pdfReaderName = "Adobe Acrobat";
      break;
    } else if (plugin.name.indexOf("Chrome PDF Viewer") !== -1) {
      pdfReaderName = "Chrome PDF Viewer";
      break;
    } else if (plugin.name.indexOf("Mozilla") !== -1 && plugin.name.indexOf("PDF Viewer") !== -1) {
      pdfReaderName = "Mozilla PDF Viewer";
      break;
    }
  }

  return pdfReaderName;
}

var pdfReader = getPDFReaderName();
console.log("PDF阅读器名称：" + pdfReader);
