如何访问我的js文件中的数据？（我只是粘贴了js文件的一小段，但需要访问每个国家/地区）
已将此添加到我的html文件中
（（JS包含我的国家/地区数据）
1.script src =“ js / a4-country-data.js”>
（我正在研究的JS，需要访问国家/地区数据）
2.script src =“ js / myscript.js”>
ar countries = [
{
"Code": "AF",
"Continent": "Asia",
"AreaInKm2": 652230,
"Population": 35530081,
"Capital": "Kabul",

}
},

}
进入我的第二个js文件
function populateRow(row,i){
row.appendChild(getTdElement(countries[i].Continent));
}
//array.js
var countries = [
{
"Code": "AF",
"Continent": "Asia",
"AreaInKm2": 652230,
"Population": 35530081,
"Capital": "Kabul",
"Name": {

"Chinese": "阿富汗",
"Franch": "Afghanistan",
"Hindi": "अफ़ग़ानिस्तान",
"Korean": "아프가니스탄",
"Japanese": "アフガニスタン",

}
},
{

}
}
