How do I detect whether bold/italic/underline is turned on in a text editor or not so that I can indicate the user whether they are turned on or not? Also how do I know whether a selected text is bold/italic/ underlined or not ?

In WYSIWYG html editors like TinyMCE, there are visual indicators (such as a different colored background) for when a user selects bold, italic etc. You can tell if text is bold, italic etc. because the editor converts text to HTML so bold text would be surrounded with strong tags, italic surrounded with em tags. Or they would have a CSS class applied to it (depends on the editor)
Can you provide some more context/ info on what are you trying to achieve?

HTML:
<button id="bold" href="#" onclick="isBold()">Bold</button>
<p id="informUser"></p>
JS:
function isBold() {
document.getElementById("informUser").innerHTML = "Bold has been clicked";
}

Hope this helps :)
