有没有办法列出用户添加的所有全局(窗口)变量？

var globalVariable = "This is a global variable";

function getAllGlobalVariables() {
  var globalVariables = [];
  var properties = Object.getOwnPropertyNames(window);

  properties.forEach(function(property) {
    globalVariables.push(property);
  });

  return globalVariables;
}

console.log(getAllGlobalVariables()); // 输出包含全局变量名的数组

var globalVariable = "This is a global variable";

function isGlobalVariable(variable) {
  for (var prop in window) {
    if (window[prop] === variable) {
      return true;
    }
  }
  
  return false;
}

function getAllGlobalVariables() {
  var globalVariables = [];

  for (var prop in window) {
    if (isGlobalVariable(window[prop])) {
      globalVariables.push(prop);
    }
  }

  return globalVariables;
}

console.log(getAllGlobalVariables()); // 输出包含全局变量名的数组
