If you're looking to dynamically add messages to the DOM without using loops, there's a simple solution. Instead of continuously appending messages, you can trigger the message addition by pressing Enter on the input field.
Here's a step-by-step guide on how to achieve this:
- Retrieve the value from the text input field.
- Insert this value into a predefined message template (in HTML) and then append it to the DOM.
To implement this functionality, you can either embed a JavaScript snippet within your HTML or include an external JavaScript file containing the necessary function:
function addMessage() {
// Perform XSS sanitization
const $messages = document.getElementById('myForm');
const $textElement = document.getElementById('textField');
const newMessage = '<div class="message-balloon">' + $textElement.value + '</div>';
$messages.innerHTML += newMessage;
return false;
}
<input type="button" id="theButton" value="Send Message!" onclick="addMessage()" />
If you prefer using jQuery, here's how you can achieve the same functionality within the JavaScript scope:
$("#theButton").off('click').on('click', function(e) {
e.preventDefault();
const $messages = $('#myForm');
const $textElement = $('#textField');
const newMessage = '<div class="message-balloon">' + $textElement.value + '</div>';
$messages.html += newMessage;
return false;
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="button" id="theButton" value="Send Message!" />
I hope this explanation has been helpful. Best of luck with your implementation!
