I ran some code in Chrome and encountered an unexpected behavior:
document.execCommand("insertBrOnReturn", false, true);
Even though I've tried setting the last parameter to true or false, the outcome remains the same: new <div> elements are always added upon pressing return.
Any suggestions on what might be missing here?
insertBrOnReturn is a specific feature unique to Mozilla browsers, as Chrome does not support it. You can verify this using the following JavaScript code:
document.queryCommandSupported('insertBrOnReturn')
To see this behavior in action, check out this example on JSFiddle. It will return true in Firefox and false in Chrome.
If you need to specifically insert <br>, you can achieve this by using:
document.execCommand('insertHTML', false, '<br><br>');

While browsing, I stumbled upon this solution that addresses an issue with Chrome adding two breaks when the cursor is at the beginning of a paragraph. By replacing the second instance of <br> with \u200C, Chrome behaves as expected, although it may not work as effectively on Safari.
document.execCommand("insertHTML", false, "<br>\u200C");
I was curious about \u200c and found more information about it here.
