为什么jQuery在鼠标移动/悬停时切换不断变化(Why is jQuery toggle continually changing on mouse movement/hover)

 通过这里的答案，我刚刚得到了jQuery中的这些代码 -  
$('.folder-items a').hover(function(){
   $(this).siblings('.file-hover').toggle();
});
 
 .folder-items a .folder-items在里面。 我希望能够悬停整个'li'而不仅仅是在实际的<a>上显示.file-hover div。  
 我已经在jsfiddle中创建了它 - http://jsfiddle.net/8Sefc/8/ - 但是当我的鼠标移动到li时，它显示/隐藏像疯了一样...  
 我认为这是我的CSS和显示：块; 宽度：100％; 李和李一个，但不能找出另一种方式来做到这一点...  
 想法？ 

I've just got this bit of code working in jQuery via an answer on here - 
$('.folder-items a').hover(function(){
   $(this).siblings('.file-hover').toggle();
});
 
the .folder-items a is within a li. I want to be able to hover the whole 'li' and not just on the actual <a> to show the .file-hover div. 
I've created this in jsfiddle - http://jsfiddle.net/8Sefc/8/ - but when moving my mouse around the li it's showing/hiding like crazy... 
I think it's something up with my CSS and display: block; width: 100%; of the li and li a but can't work out another way to do this... 
Ideas?

strcpy(t->buffer, file_name);
 
 正在写一个未初始化的指针。 您需要为buffer分配内存。 如果您使用的是Posix兼容系统，最简单的方法是使用strdup  
t->buffer = strdup(file_name);
 
 否则，您需要分配内存然后单独复制  
t->buffer = malloc(strlen(file_name)+1);
strcpy(t->buffer, file_name);
 
 在任何一种情况下，当你为每个node释放内存时，你需要free(t->buffer) 

strcpy(t->buffer, file_name);
 
is writing to an uninitialised pointer. You need to allocate memory for buffer. If you're on a Posix-compatible system, the easiest way to do this is by using strdup 
t->buffer = strdup(file_name);
 
Otherwise, you need to allocate memory then copy separately 
t->buffer = malloc(strlen(file_name)+1);
strcpy(t->buffer, file_name);
 
In either case, you'll need to free(t->buffer) when you free memory for each node
