RIOT.JS - Mixin
透過 Mixin,我們可以在標記之間共享常見的功能。Mixin 可以是函式、類或物件。考慮一個每個標記都應該使用的身份驗證服務的情況。
定義 Mixin − 在呼叫 mount() 之前,使用 riot.mixin() 方法定義 mixin。
riot.mixin('authService', {
init: function() {
console.log('AuthService Created!')
},
login: function(user, password) {
if(user == "admin" && password == "admin"){
return 'User is authentic!'
}else{
return 'Authentication failed!'
}
}
});
初始化 mixin − 在每個標記中初始化 mixin。
this.mixin('authService')
使用 mixin − 初始化後,可以在標記中使用 mixin。
this.message = this.login("admin","admin");
示例
以下是完整示例。
custom8Tag.tag
<custom8Tag>
<h1>{ message }</h1>
<script>
this.mixin('authService')
this.message = this.login("admin","admin")
</script>
</custom8Tag>
custom9Tag.tag
<custom9Tag>
<h1>{ message }</h1>
<script>
this.mixin('authService')
this.message = this.login("admin1","admin")
</script>
</custom9Tag>
custom8.htm
<html>
<head>
<script src = "https://cdnjs.cloudflare.com/ajax/libs/riot/3.13.2/riot+compiler.min.js"></script>
</head>
<body>
<custom8Tag></custom8Tag>
<custom9Tag></custom9Tag>
<script src = "custom8Tag.tag" type = "riot/tag"></script>
<script src = "custom9Tag.tag" type = "riot/tag"></script>
<script>
riot.mixin('authService', {
init: function() {
console.log('AuthService Created!')
},
login: function(user, password) {
if(user == "admin" && password == "admin"){
return 'User is authentic!'
}else{
return 'Authentication failed!'
}
}
});
riot.mount("*");
</script>
</body>
</html>
