我正在尝试将文件（存储在 Web 服务器上）读入数组。当我打印数组时，我当前得到“未定义”。这是我使用的代码：

$.get('UserFile.txt', function(data){
var array = data.split('\n');

The 'cardRules' variable never gets populated with the array data. Instead of
var array = data.split('\n');just use
cardRules = data.split('\n');
'cardRules' 变量永远不会被数组数据填充。而不是
var array = data.split('\n');仅仅使用
cardRules = data.split('\n');

Try full url instead of just relative linking
尝试完整的 url 而不是相对链接
http://yoursite.com/yourfilelocation/yourfile.txt
http://yoursite.com/yourfilelocation/yourfile.txt
$.get('http://yoursite.com/yourfilelocation/yourfile.txt', function(data){
var cardRules = data.split('\n');
console.log(cardRules);
});
$.get('http://yoursite.com/yourfilelocation/yourfile.txt', function(data){
var cardRules = data.split('\n');
console.log(cardRules);
});
