How To Edit A Link Within A Contenteditable Div

Does anyone have any suggestions on how to edit an link in a contentEditable div? It would be ideal once the link is either clicked with mouse, or the cursor hits the link, that t

Solution 1:

I'm pretty sure this is what you were looking for, however I used jQuery just to make the concept a little easier to mock. jsbin preview available, so go look at it. If anyone is able to convert this to pure JS for the sake of the answer, I have made it a community wiki.

It works by binding to the keyup/click events on the editable div, then checking for the node that the users caret is being placed at using window.getSelection() for the Standards, or document.selection for those IE people. The rest of the code handles popping/handling the edits.

jQuery methods:

functiongetSelectionStartNode(){
  var node,selection;
  if (window.getSelection) { // FF3.6, Safari4, Chrome5 (DOM Standards)
    selection = getSelection();
    node = selection.anchorNode;
  }
  if (!node && document.selection) { // IE
    selection = document.selectionvar range = selection.getRangeAt ? selection.getRangeAt(0) : selection.createRange();
    node = range.commonAncestorContainer ? range.commonAncestorContainer :
           range.parentElement ? range.parentElement() : range.item(0);
  }
  if (node) {
    return (node.nodeName == "#text" ? node.parentNode : node);
  }
}

$(function() {
    $("#editLink").hide();
    $("#myEditable").bind('keyup click', function(e) {
        var $node = $(getSelectionStartNode());
        if ($node.is('a')) {
          $("#editLink").css({
            top: $node.offset().top - $('#editLink').height() - 5,
            left: $node.offset().left
          }).show().data('node', $node);
          $("#linktext").val($node.text());
          $("#linkhref").val($node.attr('href'));
          $("#linkpreview").attr('href', $node.attr('href'));
        } else {
          $("#editLink").hide();
        }
    });
    $("#linktext").bind('keyup change', function() {
      var $node = $("#editLink").data('node');
      $node.text($(this).val());
    });
    $("#linkhref").bind('keyup change', function() {
      var $node = $("#editLink").data('node');
      $node.attr('href', $(this).val());
      $node.and('#linkpreview').attr('href',$(this).val());
    });
});

Solution 2:

I tested it only on chrome

button style

button.cmd {
 ...
}

toolbar button

<button type="button"id="linkEditor" class="cmd">link</button>

modal dialog -> link editor

<divid="optionDialog"class="modal"><divclass="modal-content"><divid="linkOption"><p><label>Indirizzo link</label><br /><inputtype="text"id="linkUrl"value=""placeholder="http://www..." /></p><p><label>Testo link</label><br /><inputtype="text"id="linkData"value=""placeholder="link label" /></p><p><buttontype="button"id="linkDone">apply</button><buttontype="button"id="cancel">cancel</button></p></div></div></div>

javascript, jquery

var cur_range;
var cur_dialog;

$(document).ready(function() {
    $('.editor').focus();

    //on toolbar button mousedown keep current range
    $('.cmd').mousedown(function(event) {
        event.preventDefault();
        try {
            cur_range = document.getSelection().getRangeAt(0);
        }
        catch(error) {
            console.log(error);
        }
    });

    $('#linkEditor').click(function() {
        event.preventDefault();

        //if user select edit link, else insert linkif (!cur_range.collapsed) {
            //if selection is a link set edit valuesif (cur_range.commonAncestorContainer.parentNode.nodeName.toLowerCase() == 'a') {
                $('#linkUrl').val(cur_range.commonAncestorContainer.parentNode.href);
                $('#linkData').val(cur_range.commonAncestorContainer.data);
            }
            else {
                //alert herereturnfalse;
            }
        }
        else {
            $('#linkUrl').val('');
            $('#linkData').val('');
        }
        //open link editor dialog
        $('#optionDialog').show();
        $('#linkOption').show();

        //store current dialog section (link, table, header)
        cur_dialog = $('#linkOption');
    });

    $('#linkDone').click(function() {
        event.preventDefault();
        if (cur_range.collapsed) {
            //insert link at caret positionvar node = '<a href="' + $('#linkUrl').val() + '" target="_blank">' + $('#linkData').val() + '</a>';
            cur_range.insertNode(cur_range.createContextualFragment(node));
        }
        else {
            //replace existing link values
            cur_node = cur_range.commonAncestorContainer.parentNode;
            cur_node.href = $('#linkUrl').val();
            cur_node.innerText = $('#linkData').val();
        }
        //update rangedocument.getSelection().removeAllRanges();
        document.getSelection().addRange(cur_range);
        document.getSelection().collapseToEnd();
        $('.modal-close').click();

        //if you don't use observer some code is nedeed//save_history(1);
    });

    //When the user clicks anywhere outside of the modal, close itwindow.onclick = function(event) {
        optionDialog = document.getElementById('optionDialog');
        if (event.target == optionDialog) {
            $('#optionDialog').hide();
            cur_dialog.hide();
            cur_dialog = null;
        }
    }
});
