希望在互联网关闭时脱机存储表单数据，并在互联网活动时提交

我有一个用户输入表，我想当互联网关闭，然后数据将继续存储在字段中。如果用户关闭选项卡并再次打开选项卡，则表单与未提交的表单保持相同。我尝试使用localstorage对象来实现这一点，但没有得到结果。我只想如果用户填写表格，如果互联网关闭了，那么表格数据将存储在本地，当互联网在手机上变得活跃，那么用户将能够提交以前填写的表格。
窗体显示窗体中的所有输入字段。javascript代码用于通过ajax提交表单，函数store用于在浏览器中本地存储数据。数据存储在浏览器中，但如果浏览器关闭而不提交，我将无法再次保留该数据。

// magic.js
$(document).ready(function() {

  // process the form
  $('.form').submit(function(event) {

    // get the form data
    // there are many ways to get this data using jQuery (you can use the class or id also)
    alert("data is here")
    var formData = {
      'name': $('input[name=name]').val(),
      'email': $('input[name=email]').val(),
      'contact': $('input[name=contact]').val(),
      'aadhar_card_number': $('input[name=aadhar_card_number]').val(),
      'aadhar_card_image': $('input[name=file_array[]]').val(),
      'gst_number': $('input[name=gst_number]').val(),
      'gst_image': $('input[name=file_array[]]').val(),
      'tin_number': $('input[name=tin_number]').val(),
      'tin_image': $('input[name=file_array[]]').val(),
      'pan_number': $('input[name=pan_number]').val(),
      'pan_image': $('input[name=file_array[]]').val(),
      'vat_number': $('input[name=vat_number]').val(),
      'vat_image': $('input[name=file_array[]]').val(),

    };
    console.log("name is here--" + name)

    // process the form
    $.ajax({
        type: 'POST', // define the type of HTTP verb we want to use (POST for our form)
        url: 'form_upload.php', // the url where we want to POST
        data: formData, // our data object
        dataType: 'json', // what type of data do we expect back from the server
        encode: true
      })
      // using the done promise callback
      .done(function(data) {

        // log data to the console so we can see
        console.log(data);

        // here we will handle errors and validation messages
      });
    alert("Submitted Successfully")

    // stop the form from submitting the normal way and refreshing the page
    event.preventDefault();
  });

});

尝试使用lokidb（内存数据库）来持久化数据。您可以将数据持久化到本地存储、索引数据库、会话存储或文件系统的任何位置。http://lokijs.org/#/docs
