JQueryMobile saving a form to a txt file - forms

Question

I'm building a app with jquerymobile and I've a page which is a form where I have to fill some info about the field job I have done so I can save it, instead of arriving to the store and fill the paperwork by guessing the time of arrival and the time of the finish.
So, I want to fill the form and when I tap on submit, it saves a txt or another file type on the android phone.
Thanks

This worked for me...
When user clicks the save button
var form_1;
var jsonString;
function saveFormState() {
form_1 = $("#form").find("select,textarea, input").serializeArray();
jsonString = JSON.stringify(form_1);
console.log(jsonString);
getFSToSaveForm();
}
function getFSToSaveForm(){
window.requestFileSystem(LocalFileSystem.PERSISTENT,0 ,function(fileSystem){
var entry=fileSystem.root;
entry.getDirectory('myForms', {create:true, exclusive:false}, function(dirEntry){
dirEntry.getFile('formToSave.json', { create: true, exclusive: false}, saveToJsonFile, onError);
}, onError);
}, onError);
}
function saveToJsonFile(fileEntry){
fileEntry.createWriter(function(writer){
writer.onwrite = function (evt) {
console.log("Wrote to file: " + jsonString);
};
writer.write(jsonString);
}, onError);
}
If you want to restore:
+Read the file and save the read text on a vaiable
Then use some Jquery.
var jsonString;
function getFSToRead(){} //You can find the code in the cordova API http://cordova.apache.org/docs/en/2.5.0/cordova_file_file.md.html
function restoreFormState() {
var newObjectArray ;
newObjectArray = JSON.parse(jsonString);
console.log(newObjectArray.length);
jQuery.each( newObjectArray, function( i, field ) {
$( '#' + field.name).val(field.value);
});
}
Hope that helps
