按钮在jquery滑块上的z-index-z-indexforbuttonoverjqueryslider

The way the code is written, the z-index properties aren't really doing anything. Since ui button is a child of lyr1, they don't share the same stacking context.

编写代码的方式，z-index属性并没有真正做任何事情。由于ui按钮是lyr1的子节点，因此它们不共享相同的堆叠上下文。

You'll need to move ui button to be a sibling of lyr1, and then you should see some results.

你需要移动ui按钮成为lyr1的兄弟，然后你应该看到一些结果。

When I tested your original code, the button was on top of lyr1 without extra css. There must be something else in the slider that is effecting the layer stack.

当我测试你的原始代码时，按钮位于lyr1之上，没有额外的css。滑块中必须存在影响图层堆栈的其他内容。
