JavaScript 获取本地 json 文件

Question

I've got this code set and a json file called statistics.json but when I log the data it says data is not defined

Anyone knows how to solve this?

const showStatistics = function(){
    fetch("../assets/statistics.json")
    .then(res => res.json())
    .then(data => {data.stats})
    .catch(err => console.error(err));

    console.log(data);
}

Answer 1

You need to log data inside callback at then , because it is asynchronous.

const showStatistics = function(){
    fetch("../assets/statistics.json")
    .then(res => res.json())
    .then(data => {
        console.log(data);
    })
    .catch(err => console.error(err));

    
}
