    Lightbulb When entering text in a comment form; I would like to use the enter key to submit.

    I've tried this jquery code but to no avail.

    Code:
    $('.cmnt_new').on('keyup', function(e) {
        if (e.which == 13 && ! e.shiftKey) {
            alert("send ajax");
        }
    });

    Here's my functions, inside the textarea "cmnt_new" I'm using straight javascript and it allows me to use the enter key to trigger a comment although it's not publishing my comment. It just refreshes and than nothing.

    Here:

    Code:
    // This function retrieves comments
    function get_comments(id ,afterCtl ,ctl) {
        var cmnt = '';
    
        show_loading('.loading_box');
    
        // Create the new row in the database - ajax returns json version.
        var add_url = '/ajax/project_comment_list.php?id=' + id;
    
        var slot = $.getJSON(add_url)
            .done(function(data) {
                // Draw the entire comment-block then display it
                cmnt = '<tr class="cmnts">';
                cmnt += '    <td colspan="11">';
                cmnt += '        <table>';
                cmnt += '            <tr class="cmnt_add">';
                cmnt += '                <td class="cmnt_text">'
                //cmnt += '                    <input type="text" id="cmnt_new" name="cmnt_new" rows="1"></textarea>';
    
                cmnt += '                    <textarea id="cmnt_new" name="cmnt_new" rows="1" onkeydown="if (event.keyCode == 13) { this.form.submit(); return false; }"></textarea>';
                cmnt += '                </td>';
                cmnt += '                <td></td>';
                cmnt += '                <td></td>';
                cmnt += '                <td class="cmnt_save" data-id="' + id + '">Save Comment</td>';
                cmnt += '            </tr>';
    
                $.each(data.ProjectComments, function (index, value) {
                    cmnt += add_comment_row(value.TEXT ,blank_if_undefined(value.EMP_INIT) ,value.ENTER_DATE);
                });
    
                cmnt += '        </table>';
                cmnt += '    </td>';
                cmnt += '</tr>';
    
                remove_comments(ctl);
    
                $(afterCtl).after(cmnt);
                $('#cmnt_new').focus();
    
                $(ctl).addClass('cmnt_active');
                $(ctl).html('&nbsp;-&nbsp;');
    
                //register the event
                $('td.cmnt_save').click(function(){
                    add_comment($(this));
                });
    
                comment_shown = id;
            })
            .fail(function(jqxhr, status, error) {
                hide_loading('.loading_box');
                show_error('There was an error pulling the comments.');
            });
    }
    
    function add_comment_row(text ,init ,dt) {
        var cmnt = '';
    
        cmnt += '            <tr>';
        cmnt += '                <td class="cmnt_text">' + text + '</td>';
        cmnt += '                <td>' + init + '</td>';
        cmnt += '                <td>' + dt + '</td>';
        cmnt += '                <td></td>';
        cmnt += '            </tr>';
    
        return cmnt;
    }
    
    function add_comment(ctl) {
        //todo: remove carriage returns
        //todo: recognize carriage return as clicking the "Save Comment" faux-button
        var cmnt = '';
    
        show_loading('.loading_box');
    
        // Create the new row in the database - ajax returns json version.
        var add_url = '/ajax/project_comment_new.php';
        add_url += '?id=' + ctl.attr('data-id');
        add_url += '&text=' + $('#cmnt_new').val();
        add_url += '&emp_init=' + $('#emp_init').val();
    
        //  find the "cmnt_last" that should change if this AJAX call is successful...
        var lastCmnt = ctl.closest('tr.cmnts').prev().find('span.cmnt_last');
    
        var slot = $.getJSON(add_url)
            .done(function(data) {
                // Draw the entire comment-block then display it
                cmnt = add_comment_row(
                    data.LatestComment.TEXT
                   ,data.LatestComment.EMP_INIT
                   ,data.LatestComment.ENTER_DATE
                );
    
                lastCmnt.text($('#cmnt_new').val());
                //todo: de-register the "expander" that might alredy be in place for the ".long_cmnt"
                lastCmnt.expander('destroy');
                //todo: stop duplicating the call to "expander", at very least, do this: "$.expander.defaults.slicePoint = 120;"
                lastCmnt.expander({
                    slicePoint: 70,
                    expandText: ' >>>',
                    userCollapseText: ' <<<'
                });
    
    
                $('tr.cmnt_add').after(cmnt);
                $('#cmnt_new').val(''); //blank the comment
                $('#cmnt_new').focus(); //put the cursor back there
    
                $(ctl).addClass('cmnt_active');
            })
            .fail(function(jqxhr, status, error) {
                hide_loading('.loading_box');
                show_error('There was an error adding the comment.');
            });
    }


    Any help would be greatly appreciated. Thank you.

    The javascript works sort of but it's not actually processing my data.<textarea id="cmnt_new" name="cmnt_new" rows="1" onkeydown="if (event.keyCode == 13) { this.form.submit(); return false; }"></textarea>';

    I just realized my submit button was targeting the wrong button and my actual button that i need to target is just a styled div... can anyone please help. i tried using the comment function in place of the this.form.submit... like so: this.form.add_comment(); no avail.
