RIOT.JS - 循环
我们可以遍历 RIOT 中的基元数组或对象,并在此过程中创建/更新 html 元素。使用“each”构建即可实现这一过程。
创建数组 − 创建对象数组。
this.cities = [
{ city : "Shanghai" , country:"China" , done: true },
{ city : "Seoul" , country:"South Korea" },
{ city : "Moscow" , country:"Russia" }
];
添加每个属性 − 现在使用“each”属性。
<ul>
<li each = { cities } ></li>
</ul>
迭代对象数组 − 使用对象属性迭代数组。
<input type = "checkbox" checked = { done }> { city } - { country }
示例
以下是完整示例。
custom7Tag.tag
<custom7Tag>
<style>
ul {
list-style-type: none;
}
</style>
<ul>
<li each = { cities } >
<input type = "checkbox" checked = { done }> { city } - { country }
</li>
</ul>
<script>
this.cities = [
{ city : "Shanghai" , country:"China" , done: true },
{ city : "Seoul" , country:"South Korea" },
{ city : "Moscow" , country:"Russia" }
];
</script>
</custom7Tag>
custom7.htm
<html>
<head>
<script src = "https://cdnjs.cloudflare.com/ajax/libs/riot/3.13.2/riot+compiler.min.js"></script>

<body>
<custom7Tag></custom6Tag>
<script src = "custom7Tag.tag" type = "riot/tag"></script>
<script>
riot.mount("custom7Tag");
</script>
</body>
</html>
