这个简单的例子将添加一个Quicktag按钮，当它被点击时调用Javascript函数。。。

<?PHP
function _add_my_quicktags(){ ?>
    <script type="text/javascript">
    QTags.addButton( \'alert\', \'Alert Button\', simple_alert );

        function simple_alert() { 
            alert(\'hello, example callback function\');
        }
    </script>
<?php 
}
add_action(\'admin_print_footer_scripts\',  \'_add_my_quicktags\');
?>

    // Add a button called \'abbr\' with a callback function
    QTags.addButton( \'abbr\', \'Abbr\', abbr_prompt );
    // and this is the callback function
    function abbr_prompt(e, c, ed) {
        var prmt, t = this;
        if ( ed.canvas.selectionStart !== ed.canvas.selectionEnd ) {
            // if we have a selection in the editor define out tagStart and tagEnd to wrap around the text
            // prompt the user for the abbreviation and return gracefully on a null input
            prmt = prompt(\'Enter Abbreviation\');
            if ( prmt === null ) return;
            t.tagStart = \'<abbr title="\' + prmt + \'">\';
            t.tagEnd = \'</abbr>\';
        } else if ( ed.openTags ) {
            // if we have an open tag, see if it\'s ours
            var ret = false, i = 0, t = this;
            while ( i < ed.openTags.length ) {
                ret = ed.openTags[i] == t.id ? i : false;
                i ++;
            }
            if ( ret === false ) {
                // if the open tags don\'t include \'abbr\' prompt for input
                prmt = prompt(\'Enter Abbreviation\');
                if ( prmt === null ) return;
                t.tagStart = \'<abbr title="\' + prmt + \'">\';
                t.tagEnd = false;
                if ( ! ed.openTags ) {
                    ed.openTags = [];
                }
                ed.openTags.push(t.id);
                e.value = \'/\' + e.value;
            } else {
                // otherwise close the \'abbr\' tag
                ed.openTags.splice(ret, 1);
                t.tagStart = \'</abbr>\';
                e.value = t.display;
            }
        } else {
            // last resort, no selection and no open tags
            // so prompt for input and just open the tag
            prmt = prompt(\'Enter Abbreviation\');
            if ( prmt === null ) return;
            t.tagStart = \'<abbr title="\' + prmt + \'">\';
            t.tagEnd = false;
            if ( ! ed.openTags ) {
                ed.openTags = [];
            }
            ed.openTags.push(t.id);
            e.value = \'/\' + e.value;
        }
        // now we\'ve defined all the tagStart, tagEnd and openTags we process it all to the active window
        QTags.TagButton.prototype.callback.call(t, e, c, ed);
    };

您应该编写一个tinymce插件，然后加载它（使用tinymce高级插件）
