前端通过字符串生成并下载txt文件

ini
复制代码
//通过a标签指定文本格式和编码直接下载
function downloadTxt(fileName, content) {
    let a = document.createElement(''a'');
    a.href = ''data:text/plain;charset=utf-8,'' + content
    a.download = fileName
    document.body.appendChild(a);
    a.click();
    document.body.removeChild(a);
}
//通过FileReader转化为base64字符串下载
function downloadByBlob (fileName, content) {
    let blob = new Blob([content], {
        type: "text/plain;charset=utf-8"
    });
    let reader = new FileReader();
    reader.readAsDataURL(blob);
    reader.onload = function(e) {
        let a = document.createElement(''a'');
        a.download = fileName;
        a.href = e.target.result;
        document.body.appendChild(a);
        a.click();
        document.body.removeChild(a);
    }
}


我用的是A链接下载
$.ajax({
  url: addressURL+''/cegtClass/queryErrorInfo'',
  data:{
    confirmKey: resData,
  },
  type: ''post'',
  success:function(res){
     var str=''<a >查看详细日志信息</a>''
     $(".uploadSuccces").append(str);
     $(".downLoadTxt").on(''click'', function () {
      downloadTxt("查看详细日志信息.txt",res);
     })
  },
  error:function(){
  }
})
