**Bug & Tip**

1.  `tip`: `button-hover` 默认为`{background-color: rgba(0, 0, 0, 0.1); opacity: 0.7;}`
2.  `tip`: `bindgetphonenumber` 从1.2.0 开始支持，但是在1.5.3以下版本中无法使用[wx.canIUse][]进行检测，建议使用基础库版本进行判断。
3.  `tip`: 在`bindgetphonenumber` 等返回加密信息的回调中调用 [wx.login][] 登录，可能会刷新登录态。此时服务器使用 code 换取的 sessionKey 不是加密时使用的 sessionKey，导致解密失败。建议开发者提前进行 `login`；或者在回调中先使用 `checkSession` 进行登录态检查，避免 `login` 刷新登录态。
4.  `tip`: 从 2.1.0 起，button 可作为原生组件的子节点嵌入，以便在原生组件上使用 `open-type` 的能力。
5.  `tip`: 目前设置了 `form-type` 的 `button` 只会对当前组件中的 `form` 有效。因而，将 `button` 封装在自定义组件中，而 `form` 在自定义组件外，将会使这个 `button` 的 `form-type` 失效。
