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