|  | ## 检测可靠的点击事件
 | |||
|  | 
 | |||
|  | 可能存在这样的情况:只有当用户真正触发click事件而不是某个脚本来模拟click事件时,才想要执行某些特定事情。 | |||
|  | 
 | |||
|  | 这个问题有一个非常简单的解决方案,javascript事件对象为我们提供了一个`.istrusted`属性,可以用它来区分。 | |||
|  | 
 | |||
|  | #### 以下是使用此方法的示例
 | |||
|  | 
 | |||
|  | ```javascript | |||
|  | // Assume there is a button in the HTML  | |||
|  |  const button = document.querySelector('button');  | |||
|  |   | |||
|  |  button.addEventListener('click', (e) => {  | |||
|  |   if (e.isTrusted) {  | |||
|  |     console.log('Button clicked by a real user');  | |||
|  |   } else {  | |||
|  |     console.log('Button click simulated by a script');  | |||
|  |   }  | |||
|  |  });  | |||
|  |   | |||
|  |  button.click() // Outputs "Button click simulated by a script"  | |||
|  | 
 | |||
|  | ``` |
