ACDLを提唱します。その2

Last updated at Posted at 2022-03-06

概要

ACDLとは、アプリは、クラウド、大切なデータは、ローカルです。
plunkerで、jsonを書き込み、読み込みしてみた。

サンプルコード

var line = {
  "maker": { 
     "name": "on" 
  },
  "genkin": {     
  }
};
var json = JSON.stringify(line); 
var blob = new Blob([json], { 
  type: "text/json" 
});
var url = URL.createObjectURL(blob);
document.getElementById("export").href = url;
var uploadFile;
document.getElementById('jsonFile').addEventListener("change", function() {
    var reader = new FileReader();
    reader.onload = function(e) {
      alert(e.target.result);        
      var data = JSON.parse(e.target.result);
      alert(data.maker.name);        
    };
    uploadFile = this.files[0];
    reader.readAsText(uploadFile);
}, true);
//alert("ok");




成果物

以上。
