应用场景
vue项目中,我们经常会模拟一些数据,比如模拟出数组文件纯在后缀是json的文件中。那么vue组件中如何引用JSON数据呢? 以下是一个示例:
示例效果
country.json文件
[
{"name": "Afghanistan", "code": "AF"},
{"name": "land Islands", "code": "AX"},
{"name": "Albania", "code": "AL"},
{"name": "Algeria", "code": "DZ"},
{"name": "Afghanistan", "code": "AF"},
{"name": "land Islands", "code": "AX"},
{"name": "Albania", "code": "AL"},
{"name": "Algeria", "code": "DZ"}
]
注意啦!
最后一个对象后面一定不能添加逗号
,否则会报错的
