有一个data.json文件，它比HTML和js_scripts文件高几级，这里是如何正确地将项目文件夹外的本地文件读入Javascript？
<!DOCTYPE html>
<html>
<body>
<select id="mySelect">
<option>football</option>
<option>Basketball</option>
<option>Hockey</option>
<option>Swimming</option>
</select>
<p>
Click the button to select the
option element with index "2".
</p>
<button onclick="myFunction()">
click me
<button onclick="Func()">
click me_2
</button>
<script>
// 1. method: read local file and show them in console.log
fetch('./data.json') // ------ > как указать к файлу на несколько уровней выше (или абсолютный путь ?)
.then(res => res.json())
.then(data => {
console.log(data)
console.log('this type:' + typeof(data)) // show data_type of data
console.log(data['Сергей']) // read by key of json
})
</script>
</body>
</html>
试试这样：
