Is it possible for a standard HTML element with defined width and height to manage characters using JavaScript, as shown in the code snippet below?
<div id="text-habdler-with-width-and-height" ></div>
<script>
$("element").getMaxChar()
</script>

Regrettably, there isn't a pre-existing function in JavaScript or jQuery to determine the maximum number of characters that can be accommodated within an HTML element of specified width and height. Nevertheless, this calculation can be achieved with JavaScript.
<div id="text-handler-with-width-and-height" style="width: 200px; height: 100px; font-size: 16px; line-height: 1.2;"></div>
<script>
function getMaxChar() {
var element = document.getElementById('text-handler-with-width-and-height');
var text = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.';
var dummy = document.createElement('div');
dummy.style.display = 'inline-block';
dummy.style.font = window.getComputedStyle(element).font;
dummy.style.lineHeight = window.getComputedStyle(element).lineHeight;
dummy.style.visibility = 'hidden';
dummy.textContent = text;
document.body.appendChild(dummy);
var charWidth = dummy.offsetWidth / text.length;
var maxCharsPerLine = Math.floor(element.offsetWidth / charWidth);
var lineHeight = dummy.offsetHeight;
var maxLines = Math.floor(element.offsetHeight / lineHeight);
document.body.removeChild(dummy);
return maxCharsPerLine * maxLines;
}
console.log(getMaxChar()); // output: 133
</script>
