完成点击事件后如何禁用另一个事件

Question

我有4 li元素，我想当鼠标悬停时（ mouseenter ， mouseleave ），每个人都为选择的每个人更改背景颜色。

我用以下代码完成这项工作：

<script>
        $( document ).ready(function() 
        {
            $('#center-group').children().on('mouseenter',function(){
                    $(this).children('.topmenu').children('.r-part').css('background-color','#810000');
                    $(this).children('.topmenu').children('.r-part').children('.r-part-bot').css('background-color','#980000');
            });
            $('#center-group').children().on('mouseleave',function(){
                    $(this).children('.topmenu').children('.r-part').css('background-color','#404040');
                    $(this).children('.topmenu').children('.r-part').children('.r-part-bot').css('background-color','#4c4c4c');
            });
        });
        </script>

现在我想当选择（ click event ）时，li的每个人都更改背景颜色，并且不进行顶级事件！ 怎么做??? 请指导我。

这个正确的代码：

$(document).on('mouseenter','#center-group li',function(){
                    $(this).children('.topmenu').children('.r-part').css('background-color','#810000').children('.r-part-bot').css('background-color','#980000');;
            });
            $(document).on('mouseleave','#center-group li',function(){
                    $('#center-group').children().not('.selected').children('.topmenu').children('.r-part').css('background-color','#404040').children('.r-part-bot').css('background-color','#4c4c4c');
            });

            $(document).on('click','#center-group li',function(){
                $(this).toggleClass('selected');
                $(this).siblings().removeClass('selected');
                $('#center-group').children('.selected').children('.topmenu').children('.r-part').css('background-color','#810000').children('.r-part-bot').css('background-color','#980000');
                $('#center-group').children().not('.selected').children('.topmenu').children('.r-part').css('background-color','#404040').children('.r-part-bot').css('background-color','#4c4c4c');
