jQuery-自行更改类

我有以下代码

$('#check-twitter').click(
    function() {                                                                        
        if ($('#ShareTwitterPublish').val() == '0') {                                                               
            $('#ShareTwitterPublish').val('1');                                                                       
            $(this).removeClass('red');                                                                               
            $(this).addClass('green');                                                                                
        } 
        else {                                                                                                    
            $('#ShareTwitterPublish').val('0');                                                                       
            $(this).removeClass('green');                                                                             
            $(this).addClass('red');                                                                                  
        }                                                                                                           
    }
);

它在我的网站上的三个不同的地方运行。在2中，它运行得很好，但在另一个中，在交换了类，值发生了变化，程序进入jQuery核心代码块后，它就全部变回了。当调试时，我可以看到我的代码被执行了，但当核心被执行时，所有的代码都被恢复了，你知道会发生什么吗？

更新：

发现了把它搞砸的代码，我在编码时似乎很粗心，在那里编码了两次，所以它被正确地调用了，但两次，因此它把值设置回了。我要给约翰·斯特里克勒答案，因为只有他发布了一个。
