								## 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" 
							 | 
						|||
| 
								 | 
							
								
							 | 
						|||
| 
								 | 
							
								```
