How to get input text value in Tizen web application

Problem Understanding

The developer wants to capture user input from a text field in a Tizen web application and access this value in JavaScript. This is a common requirement for forms and user interaction in web applications.

Solution Methods

There are two main approaches to capture input text:

1. Event Listener Method:

   • Listen for the 'change' event which triggers when the input loses focus after being modified
   • This is useful when you want to capture the value after the user finishes typing

2. Button Click Method:

   • Capture the input value when a button is clicked
   • This is useful when you want explicit user action to trigger value capture

Code Examples

1. Event Listener Method:

var input = document.querySelector('#authKey');

function onChange(e) {
    var target = e.target;
    console.log("Input value: " + target.value);
    // Use the value as needed
}

input.addEventListener('change', onChange);

2. Button Click Method:

<input placeholder="Enter text" type="text" id="authKey"/>
<button id="submit-button">Submit</button>

function buttonCallBack() {
    var inputValue = document.getElementById('authKey').value;
    console.log(inputValue);
    // Use the value as needed
}

var submitButton = document.getElementById('submit-button');
submitButton.addEventListener('click', buttonCallBack);

Additional Tips

• If you're working with multiple HTML files, ensure your JavaScript files are loaded after the DOM is ready. Place script tags just before the closing </body> tag or use the DOMContentLoaded event.
• For Tizen web applications, you don't need any special Tizen API for basic input handling - standard web APIs work perfectly.
• If you encounter null reference errors when accessing elements, verify:
  • The element exists in the current HTML document
  • Your JavaScript is executing after the element is loaded
  • There are no typos in your element IDs
