javascript - 如何在完成单击事件后禁用另一个事件

Question

我有 4 个 li 元素，我希望当悬停时(mouseenter、mouseleave)，每个元素都会为选择的每个元素更改背景颜色.

我用这段代码完成了这个工作:

<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(点击事件)时，li中的每个人都改变背景颜色并且不工作顶部事件!怎么办呢？？？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');
