Jquery显示/隐藏修复[关闭](Jquery show / hide fix [closed])

 我需要修复这个小代码：  
jQuery(document).ready(function() {

    $('.plus').click(function(){
        $('#top:hidden').show('slow');
        $('.plus').click(function(){
            $('#top:visible').hide('slow');

        });
    });
});

I need fix this little code: 
jQuery(document).ready(function() {

    $('.plus').click(function(){
        $('#top:hidden').show('slow');
        $('.plus').click(function(){
            $('#top:visible').hide('slow');

        });
    });
});

 在谷歌搜索解决方案时，我遇到了sql::Driver::threadInit()和sql::Driver::threadEnd() 。 但是，正如我在C ++连接器的1.0.5版本上所做的那样，我无法使用这些功能。 添加driver->threadInit(); 获取驱动程序实例和driver->threadEnd(); 在我的功能结束时，这个问题得到了解决。  
 以下是MySQL 1.1.0更改历史记录中提到的这个线程init和end功能：  
 
  添加了Driver :: threadInit（）和Driver :: threadEnd（）方法。 线程客户端的每个线程必须在线程的最开始时调用Driver :: threadInit（），然后才能使用Connector / C ++执行任何其他操作，并且每个线程在完成时都必须调用Driver :: threadEnd（）。 您可以在examples / pthreads.cpp中找到一个演示用例的示例。 强烈建议不要在线程之间共享连接。 理论上，如果你设置某些（未记录的）互斥锁，但它根本不受支持。 每个线程使用一个连接。 没有两个线程同时使用相同的连接。 请查看MySQL手册中关于线程的C API说明。 Connector / C ++包装了C API。 （劳伦，安德烈，乌尔夫）  
 
 TL; DR：如果您遇到此问题，请确保您的C ++ MySQL Connector版本> = 1.1.0并使用sql::Driver::threadInit()和sql::Driver::threadEnd()方法包围您的连接代码。 

While Googling around for a solutions, I came across mentions of sql::Driver::threadInit() and sql::Driver::threadEnd(). However, as I was on version 1.0.5 of the C++ Connector, these functions were not available to me. Adding a driver->threadInit(); after getting a driver instance and driver->threadEnd(); at the end of my function, this problem was resolved. 
The following is the mention of this thread init and end functionality in MySQL's 1.1.0 change history:  
 
 Added Driver::threadInit() and Driver::threadEnd() methods. Every thread of a threaded client must call Driver::threadInit() at the very start of the thread before it does anything else with Connector/C++ and every thread must call Driver::threadEnd() when it finishes. You can find an example demonstrating the use in examples/pthreads.cpp. It is strongly discouraged to share connections between threads. It is theoretically possible, if you set certain (undocumented) mutexes, but it is not supported at all. Use one connection per thread. Do not have two threads using the same connection at the same time. Please check the C API notes on threading on the MySQL manual. Connector/C++ wraps the C API. (Lawrin, Andrey, Ulf) 
 
TL;DR: If you come across this problem, make sure that your version of the C++ MySQL Connector is >= 1.1.0 and use the sql::Driver::threadInit() and sql::Driver::threadEnd() methods to surround your connection code.
