如何在javascript遗留模式下收集函数或数组函数的属性？

function collectFunctionProperties(func) {
  var properties = [];
  var propertyNames = Object.getOwnPropertyNames(func);
  
  for (var i = 0; i < propertyNames.length; i++) {
    var propertyName = propertyNames[i];
    var propertyValue = func[propertyName];
    
    if (typeof propertyValue === 'function') {
      properties.push(propertyName);
    }
  }
  
  return properties;
}

// 示例用法
function myFunction() {
  // 函数体
}

myFunction.property1 = 'value1';
myFunction.property2 = function() {
  // 函数属性
};

var functionProperties = collectFunctionProperties(myFunction);
console.log(functionProperties); // 输出：['property2']

function collectArrayFunctionProperties(array) {
  var properties = [];
  
  for (var i = 0; i < array.length; i++) {
    var element = array[i];
    
    if (typeof element === 'function') {
      var propertyNames = Object.getOwnPropertyNames(element);
      
      for (var j = 0; j < propertyNames.length; j++) {
        var propertyName = propertyNames[j];
        var propertyValue = element[propertyName];
        
        if (typeof propertyValue === 'function') {
          properties.push(propertyName);
        }
      }
    }
  }
  
  return properties;
}

// 示例用法
var myArray = [
  function() {
    // 函数元素
  },
  function() {
    // 函数元素
  }
];

myArray[0].property1 = 'value1';
myArray[1].property2 = function() {
  // 函数属性
};

var arrayFunctionProperties = collectArrayFunctionProperties(myArray);
console.log(arrayFunctionProperties); // 输出：['property2']
