A guide on dividing an input into various sections

I am looking to create an input field where users can enter coordinates in the format of 2°48'00.2"N 42°12'28.8"W. The input should have multiple fields with hard coded special characters separating them, similar to how a card expiry date is entered online. Rather than using separate inputs for each character, I would like to find a better approach that allows users to easily enter their coordinate information in one cohesive unit. Perhaps using JavaScript to concatenate the values from the different fields while still providing placeholders like [00°00'00.0"N 00°00'00.0"W] to guide users on the expected format. I welcome any suggestions or ideas on how to improve this input design. Thank you!

Answer №1

If you're looking to streamline your input formatting, consider utilizing a library like formatify.js. Check out this code snippet where I demonstrate how to implement it:

var formatifyCustom = new Formatify('.input', {
  delimiters: ['-', '/', '.'],
    blocks: [3, 3, 4],
    capitalize: true
});
<script src="https://cdn.example.com/formatify.js"></script>
<input class="input" placeholder="Enter your data" length="12"/>

Answer №2

Here is the toDegreesMinutesAndSeconds function that will provide you with the desired value. Feel free to manipulate it as needed.

let latitude = 38.898556;
let longitude = -77.037852;
console.log(convertDMS(latitude, longitude));

function toDegreesMinutesAndSeconds(coordinate) {
    var absolute = Math.abs(coordinate);
    var degrees = Math.floor(absolute);
    var minutesNotTruncated = (absolute - degrees) * 60;
    var minutes = Math.floor(minutesNotTruncated);
    var seconds = Math.floor((minutesNotTruncated - minutes) * 60);

    return degrees + " " + minutes + " " + seconds;
}

function convertDMS(lat, lng) {
    var latitude = toDegreesMinutesAndSeconds(lat);
    var latitudeCardinal = lat >= 0 ? "N" : "S";

    var longitude = toDegreesMinutesAndSeconds(lng);
    var longitudeCardinal = lng >= 0 ? "E" : "W";

    return latitude + " " + latitudeCardinal + "\n" + longitude + " " + longitudeCardinal;
}
