   I believe you can initiate a download without the need for an explicit click action from the user.  This seems to work:
   
   ```var saveData = (function () {
       var a = document.createElement("a");
       document.body.appendChild(a);
       a.style = "display: none";
       return function (data, fileName) {
           var json = JSON.stringify(data),
               blob = new Blob([json], {type: "octet/stream"}),
               url = window.URL.createObjectURL(blob);
           a.href = url;
           a.download = fileName;
           a.click();
           window.URL.revokeObjectURL(url);
       };
   }());
   
   var data = { x: 42, s: "hello, world", d: new Date() },
       fileName = "my-download.json";
   
   saveData(data, fileName);
   ```
