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>
custom7.htm
<html> <head> <script src = "https://cdnjs.cloudflare.com/ajax/libs/riot/3.13.2/riot+compiler.min.js"></script> </head> <body> <custom7Tag></custom6Tag> <script src = "custom7Tag.tag" type = "riot/tag"></script> <script> riot.mount("custom7Tag"); </script> </body> </html>
