Setting Caret at End of Text

<p>To consistently position the caret at the end of the text in all browsers, use the following JavaScript function:

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();
    }
}

Example Usage

<p>To utilize this function, attach an event listener to a button that, when clicked, calls the function to place the caret at the end of the text:

$(document).ready(function()
{
    $('#insert_caret').click(function()
    {
        placeCaretAtEnd($('#content'));
    }
});
