使用纯Javascript将Json数据导出为纯文本

var jsonData = { "name": "John", "age": 30, "city": "New York" };
var jsonString = JSON.stringify(jsonData);

function exportJsonAsText(jsonString, fileName) {
    var blob = new Blob([jsonString], { type: 'text/plain' });
    var url = URL.createObjectURL(blob);
    
    var link = document.createElement('a');
    link.href = url;
    link.download = fileName;
    link.click();
    
    URL.revokeObjectURL(url);
}

var jsonData = { "name": "John", "age": 30, "city": "New York" };
var jsonString = JSON.stringify(jsonData);

exportJsonAsText(jsonString, "data.txt");
