RIOT.JS - 迴圈
我們可以遍歷 RIOT 中的基元陣列或物件,並在此過程中建立/更新 html 元素。使用“each”構建即可實現這一過程。
建立陣列 − 建立物件陣列。
this.cities = [
{ city : "Shanghai" , country:"China" , done: true },
{ city : "Seoul" , country:"South Korea" },
{ city : "Moscow" , country:"Russia" }
];
新增每個屬性 − 現在使用“each”屬性。
<ul>
<li each = { cities } ></li>
</ul>
迭代物件陣列 − 使用物件屬性迭代陣列。
<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>
