Remove formatting from a contentEditable div

Question

I have a contentEditable Div and I want remove any formatting especially for copy and paste text.

Answer 1

document.querySelector('div[contenteditable="true"]').addEventListener("paste", function(e) {
        e.preventDefault();
        var text = e.clipboardData.getData("text/plain");
        document.execCommand("insertHTML", false, text);
    });

It is simple: add a listener to the "paste" event and reeformat clipboard contents.

Here another example for all containers in the body:

[].forEach.call(document.querySelectorAll('div[contenteditable="true"]'), function (el) {
    el.addEventListener('paste', function(e) {
        e.preventDefault();
        var text = e.clipboardData.getData("text/plain");
        document.execCommand("insertHTML", false, text);
    }, false);
});

Saludos.
