The fillForm function automates filling out web forms by taking an object of field names and values and using a custom selectDropdown function to populate dropdown menus with the specified values.

Run example

npm run import -- "map object to form"

map object to form

var importer = require('../Core');

function fillForm(obj) {
    const fields = Object.keys(obj);
    return importer.runAllPromises(fields.map(f => resolve => {
        return selectDropdown(f, obj[f])
            .catch(e => console.log(e))
            .then(r => resolve(r))
    }))
}
module.exports = fillForm;

const importer = require('../Core');
const console = require('console'); // Use the built-in console object

/**
 * Fills a form by resolving promises for each field.
 * @param {Object} obj - The object containing field names and values.
 * @returns {Promise} A promise resolving to an array of resolved fields.
 */
function fillForm(obj) {
  // Extract field names from the object
  const fields = Object.keys(obj);

  // Map over fields, creating a promise chain for each
  const promises = fields.map(async (f) => {
    try {
      // Select dropdown value and return it
      return await selectDropdown(f, obj[f]);
    } catch (error) {
      // Log any errors and continue
      console.error(`Error filling field ${f}:`, error);
      return null; // Return a default value to avoid promise chain issues
    }
  });

  // Use Promise.all to wait for all promises to resolve
  return Promise.all(promises);
}

// TODO: Consider using a more robust way to handle errors (e.g., error aggregation)
// TODO: Add input validation for obj to ensure it's a valid object

module.exports = fillForm;

/**
 * Selects a dropdown value (async implementation assumed)
 * @param {string} field - The field name.
 * @param {string} value - The value to select.
 * @returns {Promise} A promise resolving to the selected value.
 */
async function selectDropdown(field, value) {
  // Replace with actual implementation
  throw new Error('Not implemented');
}

This code snippet defines a function called fillForm that automates filling out a form on a webpage. Here's a breakdown:

Dependencies:

• importer: A custom module (not shown) likely providing utility functions and potentially Selenium integration.
• selectDropdown: Another custom function (not shown) presumably responsible for selecting an option from a dropdown menu on a webpage.

Function:

• fillForm(obj):
  • Takes an object obj as input, where keys represent form field names and values represent the desired input values.
  • Extracts an array of field names from the object using Object.keys(obj).
  • Uses importer.runAllPromises to execute a series of promises concurrently, each corresponding to filling a single form field.
  • For each field name f:
    • Calls selectDropdown(f, obj[f]) to select the appropriate option from the dropdown menu associated with the field.
    • Handles potential errors during the selection process using catch(e => console.log(e)).
    • Resolves the promise with the result of the selection using then(r => resolve(r)).

Purpose:

This code automates the process of filling out a form by iterating through a set of field names and values, selecting the corresponding options from dropdown menus on a webpage.
