JavaScript在浏览器中把文本保存为文件的方法
经过测试第二种方法可以保存更多的文本不至于卡死
var saveTextAsFile1 = function (text, fileName, success, error) {
var data = text;
if (!(text instanceof Array)) {
data = [text];
}
var file = new File(data, fileName);
var reader = new FileReader();
reader.readAsDataURL(file);
reader.onload = function (r) {
var url = reader.result;
downLoadFile(url, fileName,
function () {
success && success();
}, function () {
error && error();
});
};}/**

var export_blob = new Blob(data);
var url = urlObject.createObjectURL(export_blob);

const a = document.createElement('a')
a.href = url
a.download = '资源目录.xlsx'
a.click()
})
},
