How to read txt file

I gen’d a little mobione app that reads a text file and then saves it to localstorage. I tested this example from Test Center, webapp and native iOS app.

How it works
I know that MobiOne 1.5 improved the form processing and will perform an asynchronous GET or POST form action to a URL that I specify. So I design my UI and generate code using the Run in Test Center action. Next I manually created a data file named data.txt and copied it into my _www folder.
Note: if my app data is structured and I’m using javascript to process it then I typically prefer to structure the data in JSON format. Then I let javascript handle parsing the files content into a structured javascript object which is easy to work with

Contents of data.txt follows

data1 123 abc
data2 456 def
data3 789 ghi

Lastly I configured the Form properties of my UI and add the “Data File” button that is configured with the Submit Form action. And added logic to the form’s postSubmit handler function that will access the string contents of the data.txt file, update the UI with the text and save it to localstorage.

/**
 * Perform custom actions upon return from form submission.
 * 
 * @param {boolean} isSuccess true if all OK; otherwise false
 * @param {Object} data results of form processing; error message if isSuccess == false
 * @return {boolean} true if OK; otherwise false
 */
phoneui.postSubmitForm_m1_load_data = function(isSuccess, data) {
  // add custom postubmission processing code here,
  // e.g., parse and process results & update UI controls with data as needed
  // return false to terminate form processing
  var result = true;
  if (isSuccess) {
    // process data
    displayData(data);
    saveToLocalStorage(data);
    result = true;
  } else {
    // submit failed
    displayData("Unable to load data from text file");
    result = false;
  }
  return result;
}
