应用场景

vue项目中,我们需要通过axios获取外部的json文件资源。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
