Set Cursor position after nested contentEditable

问题:

I've got this markup

<div contentEditable="true">
    Some other editable content
    <div class="field" contentEditable="false">
        <span class="label">This is the label</span>
        <span class="value" contentEditable="true">This is where the caret is</span>
    </div>
    <!-- This is where I want the Caret -->
</div>

The caret is currently in the .field span.

I need to move it back out after the .field in the parent contentEditable.

How can this be accomplished via javascript (with the use of jQuery if needed) ?

It will be trying to trigger it on a keydown event when the caret is in the .value span as shown.

An update to the previous answer. http://jsfiddle.net/GLzKy/4/

placeCaretAtEnd($(this).parent().nextAll('.field').children('value'));

UPDATE

Updated answer with correct answer in comments

For moving directly after the current field, you might want to use range.setStartAfter and range.setEndAfter: http://jsfiddle.net/GLzKy/5

I am assuming that you want to go to this next section. To make it clear, I added a text "Here!" in a demo to show you that it does goes to the end.

In the below demo, press Enter key from the .field .value to go to the end.

Below is the function from https://stackoverflow.com/a/4238971/297641 which actually does all the work.

$('.field .value').keydown(function (e) {
    if (e.which == 13) { //Enter Key
        e.preventDefault();            
        placeCaretAtEnd($(this).closest('.parent')[0]);
    }
});

function placeCaretAtEnd(el) {
    el.focus();
    if (typeof window.getSelection != "undefined"
            && typeof document.createRange != "undefined") {
        var range = document.createRange();
        range.selectNodeContents(el);
        range.collapse(false);
        var sel = window.getSelection();
        sel.removeAllRanges();
        sel.addRange(range);
    } else if (typeof document.body.createTextRange != "undefined") {
        var textRange = document.body.createTextRange();
        textRange.moveToElementText(el);
        textRange.collapse(false);
        textRange.select();
    }
}

Tested in FF, IE8 and Chrome
