使用jquery

  <script src="./node_modules/jquery/dist/jquery.js" onload="window.$ = window.jQuery = module.exports;"></script>
  <script src="./node_modules/jquery/dist/jquery.js"></script>

save file

var app = require('electron').remote;
  const {dialog} = require('electron').remote;
  var fs = require('fs');


  document.getElementById('createButton').onclick = () => {
      "use strict";
      dialog.showSaveDialog((fileName) => {
          if (fileName === undefined) {
              console.log("You didn't save the file");
              return;
          }

          var content = document.getElementById('content').value;

          fs.writeFile(fileName, content, (err) => {
              if (err) {
                  alert("An error ocurred creating the file " + err.message)
              }

              alert("The file has been succesfully saved");
          });
      });
  };

open file

document.getElementById('openButton').onclick =()=>{
    "use strict";
    dialog.showOpenDialog((filename)=>{
        if(filename === undefined) {
            alert('No file selected');
        }else{
            readFile(filename[0]);
        }
    });
};

function readFile(filename) {
  fs.readFile(filename,'utf-8',(err,data)=>{
      "use strict";
      if(err){
        alert('An error occured reading the file.');
        return;
      }

      var textArea = document.getElementById('output');
      textArea.value = data;
  })
}

    // Note that the previous example will handle only 1 file, if you want that the dialog accepts multiple files, then change the settings:
    // And obviously , loop through the fileNames and read every file manually
    dialog.showOpenDialog({ 
        properties: [ Create Fil
            'openFile', 'multiSelections', (fileNames) => {
                console.log(fileNames);
            }
        ]
    });

            alert('No file selected');
        }else{
            var content = document.getElementById('output').value;
            fs.writeFile(filename, content, (err) => {
                if (err) {
                    alert("An error ocurred update the file " + err.message);
