Paste content as plain text in summernote editor

Question

I need to copy paste some content in my summernote editor .But when I paste, it takes the style of the page from where I have copied it.I need to paste it as plain text. Is there any solution?

Answer 1

Use the onPaste Callback

Use the onPaste option to define a callback that will strip the tags and manually insert the text.

$editor.summernote({
    onPaste: function (e) {
        var bufferText = ((e.originalEvent || e).clipboardData || window.clipboardData).getData('Text');
        e.preventDefault();
        document.execCommand('insertText', false, bufferText);
    }
});

Solve Firefox Problems:

You may still have problems with Firefox. If so, wrap document.execCommand in a timer function to delay its execution a tiny bit:

setTimeout(function(){
    document.execCommand( 'insertText', false, bufferText );
}, 10);

Update for v0.7.0+

Position of callbacks in options is changed after v0.7.0
After v0.7.0, every callbacks should be wrapped by callbacks object. (source)

This means that the original code should be written as

$editor.summernote({
    callbacks: {
        onPaste: function (e) {
            var bufferText = ((e.originalEvent || e).clipboardData || window.clipboardData).getData('Text');
            e.preventDefault();
            document.execCommand('insertText', false, bufferText);
        }
    }
});

TL;DR: Here's a functional demo

Answer 2

After v0.7.0, every callbacks should be wrapped by callbacks object. http://summernote.org/deep-dive/#callbacks

So if you are using summernote from v0.7.0 or above, jcuenod's answer could now be rewritten as:

$('.summernote').summernote({
    callbacks: {
        onPaste: function (e) {
            var bufferText = ((e.originalEvent || e).clipboardData || window.clipboardData).getData('Text');

            e.preventDefault();

            // Firefox fix
            setTimeout(function () {
                document.execCommand('insertText', false, bufferText);
            }, 10);
        }
    }
});

The onPaste-callback works great but I was having problems with the different handling of linebreaks in different browsers. So I came up with the following solution, which uses html-linebreaks:

    $(".htmleditor").summernote({
      callbacks: {
        // callback for pasting text only (no formatting)
        onPaste: function (e) {
          var bufferText = ((e.originalEvent || e).clipboardData || window.clipboardData).getData('Text');
          e.preventDefault();
          bufferText = bufferText.replace(/\r?\n/g, '<br>');
          document.execCommand('insertHtml', false, bufferText);
        }
      }
    });

Managed to make a horrible hack work for IE11. This will sadly also ask for a paste permission from the user as well. If someone figures out a better suggestion I'm all ears.

var trap = false;
$(document).ready(function () {
    $('#summernote').summernote({
        callbacks: {
            onPaste: function (e) {
                if (document.queryCommandSupported("insertText")) {
                    var text = $(e.currentTarget).html();
                    var bufferText = ((e.originalEvent || e).clipboardData || window.clipboardData).getData('Text');

                    setTimeout(function () {
                        document.execCommand('insertText', false, bufferText);
                    }, 10);
                    e.preventDefault();
                } else { //IE
                    var text = window.clipboardData.getData("text")
                    if (trap) {
                        trap = false;
                    } else {
                        trap = true;
                        setTimeout(function () {
                            document.execCommand('paste', false, text);
                        }, 10);
                        e.preventDefault();
                    }
                }

            }
        }
    })
})
