JavaScript中的方法是对对象执行的操作。JavaScript方法具有函数定义，该定义存储为属性值。
让我们看一个在JavaScript中定义方法的示例
<!DOCTYPE html>
<html>
<body>
<h3 id="myDept"></h3>
<script>
var department = {
deptName: "Marketing",
deptID : 101,
deptZone : "North",
details : function() {
return "Department Details<br>" + "Name: " + this.deptName + " <br>Zone: " + this.deptZone + "<br>ID: " + this.deptID;
}
};
document.getElementById("myDept").innerHTML = department.details();
</script>
</body>
</html>
